When people think of Specs Removal, they most often think of LASIK. But there are several options available today. At Eye7, we offer all types of Laser, Lens (ICL) and Other Procedures for Specs Removal.


 

Blade – Less Laser Procedures

In the Blade-Less technique, there are no blades working on the eye. The whole procedure is done by the use of one or combination of two lasers; Femto Laser and Excimer Laser. The precision of Femto Laser is to the levels of 5 microns. Which means that if a human hair is 60 microns, a Femto laser can cut 6 layers in that hair, which is impossible with a blade. Therefore, Bladeless technique gives greater precision, better quality of vision and more safety.

There are three types of Blade – Less Procedures

  1. Contoura Vision
  2. Blade-Less Lasik
  3. Smile

Contoura Vision is the most popular procedure and delivers results better than Lasik & Smile.
Currently Contoura Vision is available only at AIIMS and Eye7 Hospitals in Delhi. In India, it is also available at L.V. Prasad Eye Institute (Hyderabad), Sankara Nethralaya (Chennai) and Narayana Nethralaya (Bangalore)

Blade Lasik Procedures

In Blade procedures, a special blade called microkeratome is used to make the corneal flap and then Excimer Laser is used to correct the spectacle power. Modern microkeratomes are able to create flap almost similar to the ones created by Femto Lasers.

There are four types of Blade Lasik Procedures

  1. SBK (Thin Flap) Lasik with Custom Q
  2. SBK (Thin Flap) Lasik
  3. Aspheric Lasik
  4. Standard Lasik

SBK (Thin Flap) Lasik with Custom Q is the most popular procedure.

Are Laser Procedures/Lasik safe?

Contoura Vision and LASIK are very very safe procedures. These procedures are also US -FDA approved, which means they have been given safety clearance for Human Eyes. However, like any other surgical procedure it can have some complications which are extremely rare if a proper screening check is done prior to the procedure. Some patients might experience mild dryness in eyes which usually relieved by lubricating drops and disappears over time. Some may also experience temporary halos during night time which also reduces with time. Immediately after Lasik one might experience mild heaviness and blurring of vision. These are due to the effects of numbing eye drops used during procedure. All these are very very rare and can be easily managed by your doctor. Nobody in our surgical experience has ever lost sight due to this procedure.

Who is a candidate for Lasik?

To be a suitable candidate for Laser Vision Correction Surgery, you should be:

  • At least 18 years’ old
  • Your specs number should be stable for about a year – minor changes do not disqualify you
  • Your cornea should be of adequate thickness as seen by corneal scanning or ultrasound
  • Ladies should not be pregnant or breast feeding
  • You should not have eye diseases like keratoconus or dry eye syndrome
  • Controlled diabetes is not a contraindication

What if I’m found unfit for Lasik?

98% people are usually found fit for Lasik. If, however you are not suitable for Lasik, your doctor may suggest you alternative procedures for vision correction such as ICL, Advanced Surface Ablation etc.

What is SMILE? How is it different from Femto Bladeless LASIK & Contoura Vision?

Smile and Bladeless Femto Lasik are old technologies and now we have come beyond those with Contoura Vision.Smile involves just Femto Laser while the Bladeless Lasik and Contoura Vision involves two lasers; the Femto laser and the Excimer laser enhancing the precision of these procedure. Contoura Vison and Femto Lasik also offer aspheric treatment of cornea which is not possible in Smile. Aspheric treatment provides better contrast thereby improves overall visual experience. Contoura Vision also corrects corneal surface irregularities, which is not possible in Smile and Bladeless Femto Lasik, so it is able to deliver superior and 40% sharper visual outcomes than these procedures.

I want a Flapless procedure. What are my options?

No Laser Vision Correction procedure i.e Contoura Vision, LASIK, SMILE is completely flapless. The only procedure which is 100% flapless is ICL, where a lens is inserted in the eye.

What is the Protocol for Lasik?

DAY 1 – PRE – OPERATIVE CHECK UP (LASIK SCREENING)

LASIK is not right for everyone. To access your suitability for Lasik, a detailed evaluation has to be done. This is known as “LASIK Screening”. It involves a series of investigative procedures such as pachymetry, refraction, topography, dry eye testing, cornea scanning, retina screening and doctor consultation. These procedures take around 2 hours. if you are using contact lenses, it is best to remove them three days before the procedure.

DAY 2 – LASIK PROCEDURE

This procedure is done under local numbing eye drops only. No injections are used. The LASIK treatment time usually takes around 20 seconds per eye, and the whole procedure takes around 10 minutes per eye. You may leave the hospital 15 minutes after the LASIK procedure.

DAY 3 – FOLLOWUP

A followup is done next to evaluate results.

What happens during Lasik Screening?

Lasik screening is the most important and time consuming part of the whole process of Laser Vision Correction. At Eye7, Lasik screening involves a six step protocol, before he or she can be declared fit for Lasik. The screening process may take almost 2 hours whereas the Lasik procedure itself takes just 15 minutes to treat both the eyes.

The screening process includes the following steps:

1: Refraction:

A correct refraction is the most important part of Laser correction. A doctor may have the best laser equipment, but if the refraction or determining the correct power of the eye is not accurate, the results of laser correction will naturally be not optimal.

A good refraction includes the following:

  • Auto-refractometer testing: This is also popularly referred to as the Computerized eye testing. The patient is asked to bring his head in front of the machine. The chin is supported on the chin rest. The device is focused on the eye while the patient looks at a target in the body of the machine. On press of a button, the machine determines the refractive error of the eye, and the same shows on the computer screen on the machine. Three readings are taken, and the average of the three readings are used as the reference spectacle power of the eye. An auto-refractometer is a fairly accurate measuring device, and is taken as a refractive guide. Complete reliability can never be placed on this form of measurement.
  • Dilated refraction: This is the most important part of the spectacle power assessment of the eye. Pupil dilating eye drops like Tropicacyl eye drops are instilled in the eye two to three times at an interval of 5 minutes, and the patient asked to close his eyes and wait in the waiting area till the pupil dilates. This may take 20 to 30 minutes.

The optometrist now conducts retinoscopy with a retinoscope to determine the power of the eye. The patient is asked to look at a vision testing screen at a distance of 20 feet (6 meters), while the optometrist checks out the power of the eye with the help of a whole tray of miniature lenses. Dilating the pupils puts the ciliary muscle of the eye to rest, and eliminates errors in determining the true refractive power.

  • Post Mydriatic test (PMT): This is also referred to as the dry refraction, or the refraction of the person when the pupils are not in a dilated state. This is also called the true refraction or the final refraction which will be used for vision correction. This test is done atleast 24 hours after the dilated refraction. In this test, trial lenses are placed in the trial frame mounted in front of the eye. The best vision correction with glasses is determined. The dilated refraction is taken as a guide for this dry refraction. It is usually seen that the dry refraction is about 0.25 more than the dilated refraction. This difference in number is due to the relaxing of ciliary muscle of the eye due to the mydriatic effect of pupil dilating drops. NOTE – Though the above protocol is the best way to determine the most accurate refraction, not all situations warrant a dilated refraction. A simple myopia or a myopia with a small astigmatism may be treated with laser without a dilated refraction. The eye specialist decides what works best in his hands.

2: Intra Ocular Pressure (IOP) measurement

 

The human eye ball is in a shape of a globe. The core of the ball is a cavity which is filled with fluid. Fresh fluid is continuously secreted within the eye, replacing the old fluid which flows out of the eye through drainage channels. The inflow-outflow balance is able to maintain a certain pressure in the eye to keep it inflated (prevents the eyeball from collapsing). The normal IOP ranges from 12 to 19 mm of Hg.

The Intra Ocular pressure is determined by:

  • Non-Contact Tonometer (NCT): This is the Air Puff method. A metered Air Puff is directed on the cornea, and the degree of compression or applanation of the cornea is determined to calculate the pressure of the eye. This is a rapid screening method, with a slightly low reliability index.
  • Applanation Tonometer (AT): This is considered the gold standard in measuring the pressure of the eye. This test is done when the rapid screening test as done by NCT gives a suspicious reading of a high IOP. The test involves calculating the amount of pressure required to applanate (press) a portion of the cornea is read off as the IOP of the eye. Since the applanating device has to be brought in contact with the cornea, numbing eye drops have to be used. This test helps to cross check the readings of the NCT.
  • Clinical importance of IOP: Steroid eye drops are almost always used after Lasik for 1 to 4 weeks during the process of recovery. Some people have the tendency to develop a raised IOP as a result of these drops. This raised pressure is referred to a Secondary Glaucoma. A raised IOP can damage the optic nerve of the eye, if the pressure is allowed to stay high for a long time. Such people who respond to steroid drops are referred to Steroid Responders. If the normal pre Lasik eye pressure is known, the early rise in pressure can be detected, and suitable remedial measures taken. These include stopping the steroid drops, and adding IOP lowering medicines to the treatment regime. The pressure tends to regain normal values in about 2 to 3 weeks’ time. If properly managed, it is hardly ever associated with any actual loss of vision. The pressure changes as a response to steroid drops usually happen at about a week or two of instillation of these drops. The incidence of Steroid Responders is very low, still one has to be alert to this situation.

3: The corneal scanning and thickness by Pentacam or ultrasound

  • A normal thickness of an Indian cornea is around 530 microns or 0.53 mm.
  • A cornea which is less than 495 microns is considered thin and should be treated with caution.
  • A cornea which is less than 450 microns is considered very thin and Lasik should not be done on such a cornea.
  • Corneal scanning evaluates the corneal profile of the entire cornea, end to end. It also determines the ratio of the anterior to the posterior curvature of the cornea. This is useful to pick up early corneal deformities, abnormal thinning or weakness of the cornea. It is best to avoid Lasik if an abnormal pattern is seen.

4: Screening for any associated eye pathology

  • Lasik is only done on healthy eyes.
  • If an eye has any associated eye disease like Keratoconus or any other corneal pathology, glaucoma, retinal pathology etc. resulting in decreased vision, then Lasik should preferably be avoided.
  • Systemic diseases like collagen disorders like SLE. Lupus etc. should be considered a contraindication.
  • A well-controlled diabetes is not a contraindication for Lasik.

5: Retina evaluation

In myopia, the eye becomes bigger in size. As a result, the retina inside the eye gets stretched. Stretching beyond a certain limit as seen in high myopia can lead to retinal stretch marks called lattice and may be associated with abnormal thinning of the retina in these areas. Such thinned out areas may also develop a hole. Retinal holes are potentially dangerous as at a later time in life they may extend and cause a retinal tear or detachment resulting in partial or permanent loss of vision. It is important to have the retina checked by a retina specialist to rule out these situations. If a dangerous lattice or a hole is seen, it should be lasered by a retina laser to seal it. The tissue response generated by the laser takes 2 to 3 weeks to seal the hole fully. Lasik should be done after the sealing process in complete. In insignificant lattice or holes, Lasik may be done before, and the lesion may be kept in observation or sealed at a later date.

6: Dry eye testing

Lasik involves cutting and ablation of the tip of the corneal nerves during the process of laser corneal ablation, and this results in dryness. The nerves regenerate in 3 to 6 months’ time, and the dryness likewise, disappears in 3 to 6 months’ time. During this period, lubricating eye drops have to be given. However, if the eyes are dry from before, the dryness post Lasik may get aggravated, and may require more vigorous lubricant treatment or other alternatives. It is therefore important to do dry eye testing before doing Lasik

  • Shirmer’s test is considered a fairly dependable and simple test to access the tear secretions in the eye and determine the grade of dryness. A special filter paper bent at one end, is placed in the eye between the eyeball and the lower lid. After 5 min, the wetting on this strip is seen. If the wetting is 30 mm or more, the tear function is normal. If the wetting is 10 mm or less, this eye may have pre-existing dryness.

 

Tear film breakup time test is another test for evaluating dry eyes. Numbing eye drops with a special stain are put in the eye and the interval between a complete blink and appearance of first random dry spot on corneal is noted. Its normal values range from 15 to 35 seconds. A value less than 10 seconds is indicative of dry eye.

What preparations should be done before Lasik?

Preparations before coming for Lasik

  • Put the anti-biotic eye drops in both the eyes as recommended by your eye doctor, 6 times a day, one day before the procedure.
  • Do not use perfumes, powder, makeup on eyes and face on the day of Lasik.
  • It is preferable to stop using contact lens 1 week before surgery. A small relaxation is permissible in consultation with your doctor
  • Wash your hair on the day of Lasik so that you don’t feel the urge to wash them for next 2-3 days.
  • Take a normal light meal before coming for Lasik.

On reaching the Lasik centre

  • A final re-check on your vision will be done by an optometrist
  • You would be asked to sign a consent form
  • Just before the procedure, an instruction card will be given to you. Read the instructions carefully
  • A Lasik executive will explain the steps of the procedure to you

During Lasik

  • Lasik is done on both eyes in the same sitting
  • It takes about 15 minutes to do Lasik on both the eyes
  • The actual laser time is about 10 seconds per eye
  • If you are undergoing a bladeless Lasik or Contoura Vision, you need to go through two laser machines, a Femto laser and an Excimer laser, however, if you are undergoing any other Lasik type, you need to go through only an Excimer laser
  • Under the Excimer laser, you are to fix your sight to a green blinking light in the machine
  • Numbing eye drops will be instilled in your eyes
  • The procedure is pain free
  • There are no injections used
  • No bandage is used on the eyes

What should be expected immediately after Lasik?

  • It is a walk in – walk out procedure and the person can be sent home 15 minutes after the procedure.
  • Immediately after the laser treatment, you may feel heaviness in eyes because of the numbing eye drops. There is also a little fogging of vision which starts clearing up in about 40 minutes.
  • As the effect of the numbing drops wears off, you may experience some grittiness, irritation and watering from eyes. This may last for a few hours.
  • You are advised to put on dark glasses before leaving the centre. Dark glasses are essentially protective for the eye against dust and from fingers inadvertently rubbing the eyes. No protection is required from room light and day light.

By next day the vision is fairly clear, however some people may experience mild variations due to varying healing patterns of the eye.

What precautions should be taken after Lasik?

    • Do not touch your eyes with fingers. Mop tears with soft tissue paper. Do not use handkerchief
    • Keep your eyes closed as much as possible after laser treatment on the laser day.
    • Eye drops to be started on the laser day. Pull lower lid and place one or two drops on the eye in the gap between the lid and the eyeball
    • Wear dark glasses continuously throughout the day for the first 3 days. On the first three nights, use protective eye shields provided to you by the Lasik centre. From 4th day onwards, use dark glasses only when outdoors up to 15th day. The purpose of dark glasses is to prevent your hands from rubbing the eyes. It also serves as a small protection against dust. Exposure to sunlight or room light is not harmful to the eyes.
    • Stay in clean environment- Avoid kitchen and smoke for 1 week.
    • Mobile phones may be used from the next day
    • Computer use, watching TV, reading etc. can be started from the 2nd day in moderation. There may be strain on eyes initially which is normal.
    • Take a bath neck down for 1 week. During this period, clean your eyelids lightly with boiled cotton once in the morning to remove deposits from the lid margin, taking care not to touch the black portion (cornea) of the eye. Wipe face lightly with a clean towel without rubbing your eyes.
    • From 2nd week onwards, take a normal bath from head downwards with your eyes closed as a precaution. A little water entering your eyes now is a very low risk.
    • After 2 weeks, you can return to normal bathing
    • Light activities can be done the very next day. Do not do heavy exercises for 7 days. Sports activities can be done after 1 month.
    • You can have your normal food after laser treatment.
    • Avoid car driving for 2 days, and driving a bike for 2 weeks.
    • Do not splash water into eyes for 2 weeks. Splashing water into the eyes as a habit is best avoided as it washes away all the natural oils of the eye, inducing dry eyes. Splashing to wash away some dust particle is acceptable
    • Smoking and drinking to be avoided for two weeks.
    • Do not use any eye make up for 2weeks. Threading of eyebrows may be done after 2 weeks taking care to avoid too much pressure on the eye.
    • Facial massage should be avoided on the eye area for 3 months.
    • Avoid vigorously rubbing your eyes for 3 months.
    • Avoid swimming, water diving for 3 months.
    • Cosmetic contact lenses can be used after 3 months.

    After laser surgery, follow-up visits till 6 months are free at your Eye7 centre

Does the procedure hurt?

The laser procedure itself does not hurt. A slight pressure may be felt during the procedure. There is a possibility of some degree of discomfort after the procedure for 3 to 4 hours, which is easily controlled by medication. If discomfort persists, you should contact your eye doctor.

I’m planning to get Lasik done, how many days’ leave should I apply to the office?

Laser vision correction are walk in walk out procedure and in most of the cases both the eyes can be operated the same day. However, before the treatment one has to get a screening workup done which includes 6 investigations and takes about 2-3 hours. After the procedure majority of the people can return to work after 2-3 days. Most of the routine work can be done after 7 days. Jobs that are more physically demanding and involve exposure to liquids or dust might require a more graduated return to full activities, but are best discussed with your surgeon.

Will I be totally free from spectacles?

97% of the people will be totally free from their spectacles. 3% will have mild variation from their zero targeted correction due to varying healing patterns in different individuals, but will have their dependency reduced on spectacles. After 3 to 6 months’ laser enhancement can be attempted to correct these individuals further. People over the age of 45 who opt for distance vision correction, may need reading glasses.

What are Limitations of Lasik?

When we think of correcting vision, we think of Laser or Lasik. Lasik is the ideal procedure for vision correction. Day by day, as the technology is advancing, so are hopes and expectations from Lasik. But even with the latest techniques of LASIK, there are always situations where Lasik cannot be done. Limitations of Lasik can be described as follows:

 

1: Limitation of age:

  • Minimum 18 years:By 18 years, the number tends to become stable in most of the people. However, in a human system, there can be no hard and fast rule. This means that in some people the number may become stable even by 16 years, while in some it may not be stable even at 22 years. Even if the number is stable by 16 years, Lasik should preferably not be done at this stage, because the future cannot be predicted, and if the number increases later, it can only lead to regrets. As a general observation, it is seen that low numbers like -1.0 to -3.0 tend to become stable even before 18 years of age. Numbers from 3.0 to 6.0 may become stable by 18 to 20 years. Number from 6.0 to 9.0 may become stable by 22 years, while numbers beyond 9 may or may not be absolutely stable even beyond 22 years.
  • Maximum age:There is no limit to maximum age. We have done Lasik in people even at the age of 60 years. It is a question of when one decides in life that enough is enough, and that one would like to see the world without these ‘optical crutches’. In our personal experience of 20 years of Lasik, we have seen that Indians usually accept glasses as part of their identity by the age of 40. Rarely have I seen people asking for Lasik beyond this age. However, in the last few years, I have noticed a definite social change. Mothers and father of children, who have got Lasik done successfully, are now asking whether they too can get rid of their glasses at this stage. So, I would now put the Indian mind set at 50, and the western country mind set at 60.
  • Ideal age:There is always an age band when people feel that this is the ideal age for Lasik. We feel that this band is within the age of 20 to 40 years. During this period, there is a strong desire to look good without glasses. Matrimony is a major reason in India, while other reasons like lifestyle freedom, sports, personality enhancement and self confidence booster play an important role.

 

2: Limitation of pregnancy or breast feeding:

Lasik is not advisable during pregnancy or breast feeding. During this period, the hormonal levels in the female body are high, and there is an associated relaxing of tissues and increase in spectacle power. Even though this increase in spectacle power may happen in only 10 % of the ladies, still this number is pretty high to caution against Lasik during this period. In those females where the number increases during pregnancy, it is observed that the change is usually between 0.5 to 1.0 D spectacle power. It is also observed, that if the spectacle power increases in first pregnancy, there may be a similar increase in the subsequent pregnancy.

 

3: Limitations of corneal thickness:

Cornea should be adequately thick to perform Lasik. Too thin a cornea becomes is a limiting factor. A normal Indian cornea has a central thickness of 530 microns or 0.53 mm. In this thickness, one can safely correct a number of -8.0 by SBK (thin flap Lasik) or the Bladeless Femto lasik. A cornea which is less than 495 microns is considered thin, while a thickness of less than 450 microns is a ‘no go’. The natural assumption from these figures is that if the cornea is thicker than 530 microns, then more spectacle number can be corrected. This is not correct as treatment of more than -8.0 leads to excessive flattening of the cornea and resultant disturbances in vision called spherical aberration. It is therefore recommended that the ideal upper limit is -8.0, while the acceptable upper limit is -10.0. Beyond this number, Lasik should be avoided, and a better way would be to go in for an ICL. The upper limit of correction by Lasik for a plus number i.e. hypermetropia is +5.0.

 

4: Limitations of corneal curvature:

Too flat a cornea or too steep a cornea can also be a limiting factor.

  • Flat Cornea:A normal human cornea has a curvature of 44.0 D. A cornea with a curvature of 41.0 D or less is considered a flat cornea. Since Lasik involves lifting up of a cornea flap, in a very flat cornea, the size of the flap lifted may be too small. This means that the area of cornea available for laser treatment may have to be reduced, which may result in visual problems like halo’s and glare around lights at night. Femto Second Laser made flaps do better even in flat cornea.
  • Steep Cornea:A cornea which is more than 48.5 D is considered a steep cornea. In such steep corneas, lifting the flap may result in button holing of the flap, or an irregular thickness of the flap. This happens in only a very small percentage of steep corneas. In case of button holing of the flap, the flap is re-positioned bask without doing the laser treatment, and allowed to heal. The flap may be re-lifted after 3 months, preferably with a Femto Second Laser, as the latter gives more dependable flaps in extremes of corneal curvatures.

5: Limitations in corneal pathology:

Keratoconus is a corneal condition where the corneal tissue is inherently weak. Due to the normal eye pressure within the eye ball, the cornea starts bulging out. This makes the cornea steep and irregular. Rays of light entering the eye through such corneas get irregularly scattered thereby resulting in loss of quality of focus and decrease in vision.
Lasik involves ablating the cornea to change its curvature. Ablating the cornea makes the cornea thin. Acceptable level of thinning does not weaken a healthy cornea. However, in an inherently weak cornea, the Lasik induced thinning may weaken the cornea to an extent that it will start to bulge causing optical distortions and decrease of vision. This abnormal bulging of the cornea may then be stopped by ‘C3R’ or what is called Collagen Cross Linking.
The importance of cornea screening is to detect sub-clinical or hidden Keratoconus, and reject these cases, so that the rest of the eyes undergoing Lasik treatment are safe. With modern methods of corneal scanning like Pentacam, it is possible to detect most of these hidden Keratoconus cases, thereby making lasik very safe. However, very rarely, one may still have to face a tricky situation, and Collagen Cross Linking may then have to be done to arrest the progress of the disease.

For how long will I have to put medications?

Usually a patient is on medicated eye drops for 4 weeks and has to use lubricating eye drops for at-least three months

Can I wear spectacles or contact lenses after surgery?

If the need arises they can be used. Cosmetic contact lenses can be used three months after Laser surgery after consulting your eye doctor.

Can I use eye makeup/ cosmetics after surgery?

Eye makeup can usually be used after two week of treatment. However, one should consult a doctor before for the same.

Will I ever get glasses after Laser treatment?

After Laser treatment, eye behaves like a normal eye. This means that you may require glasses for reading after 40 due to normal ageing process of eye.

Will this treatment have any effect when I undergo a Cataract Surgery later in life?

When you plan to undergo a cataract surgery later in life, one should inform the doctor about any previous procedures so that the treatment plan can be modified accordingly.

I wear contact lenses regularly; do I have to take any extra precautions?

Usually the contact lens wear has to be discontinued for 3 days before you can undergo Laser treatment. However such should be discussed with your doctor who can suggest you the precautions in advance.

Are the results achieved from Lasik permanent?

The effects of Lasik on the cornea are permanent. Sometimes, internal changes within an eye may come with age and these may have some effect on the overall visual status. For example, myopia may progress even in later years, or a person may require reading glasses with normal ageing process usually seen after 40 years of age.

What is the worst possible complication?

Infection is a serious complication and could lead to deterioration of the cornea. Infection is usually rare and can be well controlled with medications with little or no loss of quality of vision. At our Centre, we have had no case of infection till date.

How would the eye behave after 30 years?

The medical community can only speak of the future by accessing the data from the surgeries performed within the last 20 years. The data reveals a very positive healing response of the eye giving doctors no reason to be concerned about effects beyond 30 years.

Can both eyes be done the same day?

Yes, in most of the cases. However, one eye may be done at a time by choice.

Have any doctors had Lasik correction themselves?

Yes, many in India as well in several other countries. We have also operated on several doctors including eye specialists.

Will I get dry eyes after Lasik?

Before every Laser Procedure, a detailed examination is done for dry eyes to ensure you have a comfortable experience after surgery. Some patients might experience mild dryness in eyes after the procedure, which usually relieved by lubricating drops and disappears over time. If however you are found to have dry eyes before procedure, your doctor may suggest you alternative procedures such as ICL which are considered best in such situations. These are best discussed with your doctor.

Can I drive home after Lasik?

No. Even though vision is fairly clear after Lasik, one might experience heaviness and blurring immediately after the procedure. These are due to the numbing eye drops used during the surgery. Also one might experience sensitivity to light and watering. It is best to ask you friend or a family member to take you safely back home. Also you will be required to wear protective glasses to prevent touching the eyes accidently and avoid any exposure to dust etc. During the next follow up the doctor will check your vision suggest accordingly. A patient is legal to drive when one eye is seeing 6/9 (20/30) or better. In practical terms, drive when you are comfortable with the newly set vision.

What is cost of Lasik?

Lasik laser is synonymous with eye sight correction. People today have become so much aware about laser vision correction from the net and other sources that they are directly asking for Lasik on entering an eye centre. For many, cost of lasik is a determining factor

 

But before we come to cost, it is important to understand that Lasik is not the only method of vision correction but there are many other options such as Surface ablation procedures, ICL, RLE, Intacts. In Laser Vision correction only there are 7 options as mentioned above.

 

The cost of all the above are so varied, and the reasons for choice of these procedures so different, that giving cost of all the procedures is bound to confuse a person. Also, not all centres offer all procedures, and many centres offer just 2 or 3 options. The fact that there are soo many options for vision correction means that there is no one option which suits all.

 

The first step in deciding the cost is to find out which procedure is the most suitable for a given eye. For this, a detailed eye evaluation is needed, which takes about an hour. Then the doctor evaluates the data and gives the appropriate option to the person wanting vision correction. The choice will again depend on what options the doctor holds in his premises.

 

Blade – Less Laser procedures are considered premium procedures as the offer high safety and best visual outcomes, therefore bladeless procedures are prized marginally higher than Blade Procedures.

For somebody very low on budget, it can be said that basic Lasik at an Eye7 centre costs Rs 20,000/-. Contoura Vision is the costliest and the best, while SBK is placed in-between the two options.

How long does LASIK take?

The laser treatment itself usually takes around one minute. The whole procedure takes about 10 minutes for one eye.

Can Lasik also correct reading vision?

Lasik is usually done to correct vision for distance. For correction of near vison in Elderly/Presbyopia please read vision correction in special cases.

How many checkups will I need after Lasik?

Followups after Lasik are usually done the next day, next week and then monthly for 2 months. However these are best suggested by your doctor.

When can I return back to work?

After the procedure majority of the people can return to work after 2-3 days. Most of the routine work can be done after 7 days. Jobs that are more physically demanding and involve exposure to liquids or dust might require a more graduated return to full activities, but are best discussed with your surgeon.
