LASIK is currently the best method of correction of refractive errors. It is accurate, effective and safe.
In LASIK, a very thin (110 to 160 micron) layer of the cornea (the transparent part of the eye) is raised using computer controlled ultra precision microkeratome. * The cornea is then reshaped into a predetermined curvature using the state of art and extremely precise VISX Star S4 IR Lasik laser. This leads to the correction of myopia, hyperopia and astigmatism. The procedure is short and simple, and being computer controlled, is highly accurate.
Computer-controlled pulses of light energy or laser is used to reshape the cornea. Visx Star S4 IR Lasik Laser resurfaces the cornea to a desired corneal resurfacing. It's able to remove tissue with accuracy of up to 0.25 micron with each pulse.
The corneal flap is then repositioned and allowed to dry for a few minutes. The flap self seals without the need of any stitches.
Only protective glasses are to be used, bandages are not required.
A contact lens is placed on the eye as a bandage in the eyes. A medical professional will remove the "bandage" contact lens once the epithelium heals.

PRK is performed when there is no adequate thickness to raise the flap for LASIK.
PRK is also widely done and practised as LASIK.
Here, corneal epithelium is removed instead of taking a corneal flap and an excimer laser is applied to reshape the cornea.
It will take a minimum 3 days to get a complete epithelial healing.
You can have light sensitivity, watering, foreign body sensation in the eyes.
Microkeratome related difficulties are not there for PRK.

It is extremely important to determine who is a suitable candidate. The important criteria are:

Refractive error:
- Myopia between -1 to -8.50 diopter
- Hypermetropia up to 6 diopter
- Astigmatism up to 6 diopters
Minimum Age: 18 years
Refraction: Should have been stable for the last one year.

Prior to your LASIK, your doctor will review your medical history and perform a thorough eye examination to:

Your doctor may also give you the following preoperative instructions:

LASIK/PRK is a painless procedure that is performed under local anaesthesia and usually takes about 15 minutes. No injection is required.

Your surgeon will first numb your eye with anaesthetic eye drops.
An eyelid holder will be placed on your eye to prevent the eye from blinking.
You will be asked to focus on a target light so that the eye remains still.
In PRK, the outer layer of epithelial cells from the cornea is removed using an alcohol solution.
In LASIK, the microkeratome will raise the outer epithelium (this refers to creating the flap).
The laser is applied to reshape the cornea.

LASIK is done as a day care procedure, with no need to get admitted in the hospital.

You may experience sensitivity to light, blurred vision, or tearing.
There will be some discomfort - photophobia (light sensitivity), watering in the eyes on the first day.
