What LASIK does to the eye

LASIK ( Laser assisted in Situ-keratiomiulesis) is a surgical procedure that corrects the common eye defects with the help of laser aids . A laser or blade is used to create a thin flap in the cornea and remove certain tissues which in turn helps in redirecting the light to fall on it and improve vision .

Types of LASIK

Depending on the preference of a patient and the available technique a LASIK may be Conventional , IntraLasik or a PRK form of surgery .
In each case a different procedure is adopted to correct the defect .
On one hand where the IntraLasik technique allows a person to opt for blade free treatment , PRK hasn’t gained too much popularity due to its low success rate . This technique May tend to work better with people who have thin corneas or who May suffer from chronic dry eye . Also this technique uses the longest recovery time . The blade free LASIK on the other hand is more popular since it avoides any incision and post surgery discomfort.

Recovery time :
The healing process starts almost immediately after the surgery . People often get discharged within a few hours and also return to their usual routine within 24 hours .

Risk factors :
Fortunately LASIK eye surgery does not have any adverse effects . So far the patient satisfaction and success rates have been significant and sight threatening reports, if any have been extremely rare .
Also if side effects occur in a particular case , they too can be treated via advanced surgical procedures or medical treatment
