Indian army/air force accepts refractive surgery but there are certain conditions. The principal criteria are that the individual must be older than 20 years before undergoing surgery, and that it ought to have been done 6 months or 1 year before the medical examination. Individuals with high refractive errors (>6D) prior to LASIK are to be excluded. Candidates must not suffer from colour or night blindness. Candidates who have undergone LASIK/SMILE fulfilling above criteria may be considered for joining defence forces. (Ref: http://www.careerairforce.nic.in)
