Clinical observation of cutting fluctuations on central corneal thickness after laser subepithelial keratomileusis

Abstract

AIM:To evaluate the percentage of cutting fluctuations of central corneal thickness(CCT)intraoperative used low concentration(0.02%)mitomycin C(MMC)after laser-assisted subepithelial keratomileusis(LASEK). METHODS: In this prospective study, low and medium myopia group(spherical equivalent≤6.0DS)has 138 patients(276 eyes). Low concentration MMC used topically in 69 patients(138 eyes)randomized after excimer laser ablation; the another traditional LASEK as control. High myopia group(6.0DSt test and their repeatability was assessed using the coefficient of variation(CV).RESULTS: At 3mo after operation, the difference of central corneal thickness and cutting value between different treatment groups was statistically significant(PPPPCONCLUSION: The study on percentage of cutting fluctuations of central corneal thickness, further confirmed low concentrations MMC in reducing postoperative corneal stromal proliferation reaction, inhibition of haze production.
