I am 18 years old. My right eye and left eye powers are -7.25 and -6.50 respectively. I wear specs from very childhood. For last 1 and half year, power is changing very slightly between 0.25 to 0.5. I have gone through pre test for lasik surgery few days before and found that the cornea is fit for surgery. Pl give me expert opinion whether I need to wait for some more years or go for lasik.
