###Human: Is applying MMC in LASEK surgery safe enough? ###Assistant: Hello. Applying MMC (Mitomycin-C) in LASEK is safer and in many studies, it has not caused any problems. So, you need not worry. Coming to your second question, LASIK with 370 µm left, is very safe as we take the safety level as 250 µm. Hence I feel LASIK risk is lower.
