What is the spectacle number that can be corrected by Lasik?

-1.0 to -18.0
+1.0 to +8.0
This includes spherical and cylindrical combinations. The limits of correction will vary in different individuals depending on the thickness of the cornea.

What are the minimum requirements?

The person should be at least 18 years of age and should have a near stable spectacle power for one year.

How is Lasik laser performed?

Lasik requires extensive pre-operative computer analysis of the eye. The spectacle user is then asked to come on the scheduled day for the laser treatment. Local anaesthetic eye drops are instilled in the eye to achieve a pain free procedure. The patient is now made to lie under the laser machine and asked to fix his gaze at a red light. The data of the patient is fed into the computer memory of the laser. A special machine called the microkeratome is used to pick up a thin corneal flap of 160 microns. Laser is delivered to the cornea under this flap to correct the spectacle number. It takes 20 to 60 seconds to complete the laser delivery to one eye. The corneal flap is placed back in position where it holds strongly within two minutes due to its natural bonding properties. The entire procedure takes about 10-15 minutes.

Is this procedure painful ?

No, a sight pressure on eyes may be felt during procedure. Some people may feel slight discomfort for 2-3 hrs after the procedure which can easily be controlled by medicine.

Will I be totally free from spectacles?

95% of the people will be totally free from their spectacles. 5% 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.

Will I never have to use spectacles again?

Your eye will behave like any other normal eye. It will also undergo age related changes like a normal eye. Hence after the age of 45 you may need reading glasses.

When can I return to work?

After 2 to 3 days

How safe is this procedure?

Lasik is a very safe procedure but like any other surgical procedure it can have some complications which are extremely rare and usually insignificant. Nobody in our surgical experience has ever lost sight due to this procedure.

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.

How long will I be on medications?

Generally speaking a patient is on eye drops for 3 to 6 weeks. This is dependant of the level of correction attempted and the individual healing response.

Have any doctors had Lasik correction themselves?

Yes, many in India as well in several other countries. This also includes several eye specialists.

Can I wear spectacles or contact lenses after Lasik surgery?

If the need arises they can be used.

What are the other procedures for the removal of spectacles?

The first popular procedure was radial keratotomy (R.K.). In this radial cuts were given on the cornea by diamond knife which compromise the strength of cornea permanently. This procedure was able to correct 3 to 6 diaopters of myopia only. Many times mild to total reversal of spectacle number occurs. With introduction of excimer laser P.R.K. came into practice. It was more safe and predictable (accurate) for lower spectacle number but there is discomfort for 3-4 days requiring bandage. It requires prolonged (upto 6 months) medication after procedure. It may leave some haze on central cornea. Lasik overcomes all these problems thus making it safest and more predictable even in higherspectacle numbers.
