Ans. Dry eyes need to be examined before LASIK. If one does LASIK on a pre existing condition like dry eyes, yes, the dryness can get aggravated. However, many centres do not do a detailed analysis of this prior to LASIK. If we find you having dry eye from our quantitative tests and qualitative Tests like Schirmers and TBUT (Tear Break Up Time), then you are graded and marked as mild, moderate or severe dry eyes with a scoring and a certain TBUT time is specified. Then the treatment is planned accordingly. If moderate or severe dry eye, then LASIK can definitely not be done first. This needs to be first treated and then monitored to see if the score is improving after the treatment.
If there is mild dry eye, or you have an occupational situation wherein we find that you are in a high probability of getting dry eye in future, then EpiLASIK (a modification) in initial steps of LASIK is then advised.
Dr Shroff will be conducting this examination himself and will be in the position to tell what is best only after this initial checkup. In LASIK, the reason for aggravating dryness is because there is necessity to create a ‘flap’ on the cornea. This disturbs the corneal nerve supply and may cause dry eyes post treatment, usually temporary.
However, in cases where we would not like to aggravate an already existing dry eye situation which is in control, then we prefer doing LASIK with no flap being made (No cut, no flap LASIK- Bladeless),.
The only downside being a longer time period in recovery, about 4 days more than LASIK and need to use specific eye drops for 3 months.
