It is a fact that after lasik laser operation in the yr 2000, I got much relief , now that I have again got almost the same condition with regard to ref error in both eyes (+3.5 cyl no.near,+2.5 cyl far), will it be completely safe (without any long term or permanent damage or side effects)for me to go for second lasik laser or should I keep on using glasses (which I feel difficult),If it is yes for Lasik then which lasik is the best?Any other advanced. ref. error correction techniques / solutons may also be suggested Pl. I will be very thankful sir.
