LASEK with MMC prevents haze in patients unsuitable for LASIK

LONDON — Mitomycin-C can allow surgeons to perform LASEK in patients who are unsuitable for LASIK, according to a surgeon speaking here.

Iwona Liberek, MD, of the Medical University of Warsaw, Poland, reviewed her 2-year results of 968 patients treated with LASEK and with 0.02% mitomycin-C (MMC) for medium to high refractive errors. She presented her findings at the European Society of Cataract and Refractive Surgeons annual meeting.

Patients had been selected for LASEK because of insufficient corneal thicknesses for LASIK, Dr. Liberek said. MMC was applied with a Spongostan film for 0.5 to 1 minute after ablation.

At 28 months' follow-up, late haze had appeared in just 61 patients, she said, noting no patients required re-operation.

"For the LASEK procedure, the use of mitomycin-C allows for qualifying patients with large errors for whom it would be dangerous to undergo the LASIK procedure," Dr. Liberek said.

"Based on 2 years of observation, the use of mitomycin-C seems to be a safe method to prevent such complications as haze, which is confirmed by confocal microscope examination," she said.
