When is the best time for lasik?i'm about to turn 21 and use high power lenses.when is the apt time.and please do mention side effects if any.

23 years: Generally age 23 is the usual cut off as the eyes change too much prior to that age to allow for stability of the eye power. Lasik can be quite effective although there are limits to the power (usually -10 or above). The usual side effects are not quite enough power and eye dryness and a few more rare issues usually reversible. Discuss with a lasik surgeon in your area.

Timing for LASIK: The time for lasik is when the eye stops changing. For girls this can be as early as 18 and for boys may be as late as 22 or 23. By that time, essentially everyone has stopped growing. http://www.doctorsforvisualfreedom.com/questions-lasik.html.
