This procedure involves first creating a thin flap of cornea with an instrument called the microkeratome. Followed by lifting of the flap and laser treatment to reshape the cornea. The flap is then repositioned in its original place. Improvement in vision is noted right from the next day. The beam profile of Wave light laser has been wave front optimized, hence it removes lesser amount of corneal tissue when compared to other laser machines, thus making the treatment more safer for your eyes. Wavefront optimization also ensures that you do not experience any glare or halos during the night while looking at bright lights. Wavelight laser allows multiple options for customized treatments, such as wave front guided, topography guided, Q factor guided treatments. Such treatment modalities are far superior when compared to those with other lasers such as zyoptix, custom vue, or custom cornea

• Am I eligible for LASIK?
• While most patients are eligible for LASIK, not everyone is.
• An ideal candidate for refractive surgery ?
• Must be atleast 18 years of age with stable refraction for 1 year.
• No associated eye diseases.
• No connective tissue disorders.
• Must discontinue contact lens wear 2 weeks prior to refractive surgery.

Eligibility also depends on the amount of refractive errors , the curvature and thickness of the cornea and a number of other factors that an ophthalmologist must evaluate. Proper patient selection is vital for successful refractive surgery and a satisfied patient.

Will my vision improve immediately?
There is a considerable improvement in unaided vision following the treatment. Following PRK the vision improves 3-4 days later once the surface healing in complete. Following LASIK this improvement is noted right from the next day. However a slight fluctuation of vision may occur over the next few months as the healing process continues. 

What are the possible side effects?
Usually most patients are quite comfortable following LASIK. There is a moderate amount of pain following PRK on day 1, which reduces subsequently. There may be transient light sensitivity, glare & foreign body sensation, or dryness in the treated eye. Sometimes there may be a slight under correction or over correction following the procedure.

Will I need to wear glasses or contact lenses after the procedure?
Both PRK and LASIK are designed to allow you to discontinue the use of corrective lenses for routine daily work. In some patients with higher refractive errors corrective lenses of lower power may still be required following the treatment. In some individuals this residual refractive error can be corrected by a second refractive procedure

When can I resume normal activities?
You can return to work after 3 days if PRK has been performed. Following LASIK you can return to work the following day. While most activities can be resumed, it is better to avoid swimming, contact sports etc at least for a one-month duration.

Are the results of LASIK permanent?
LASIK permanently removes corneal tissue to reshape the eye in order to improve refraction. The physical results are permanent. However, you should be aware that since the eyes can still change with time, LASIK does not prevent presbyopia or affect this condition once it does occur.

Should I undergo LASIK?
Ophthalmologists all over the world have been reshaping the cornea using the excimer laser since the 1980s. LASIK has been performed internationally for approximately 10 years now. While refractive surgery does not promise perfect vision, it does hold the promise of reducing one's dependence on contacts or glasses. For many people the reduction will allow them to more freely pursue their hobbies, sports activities or career options.
