高度近视LASIK术后5年屈光回退的多因素分析
Multiple factors analysis on refractive regression five years after laser in situ keratomileusis for high myopia
摘要
Abstract
Objective To evaluate the regression relevant factors of laser in situ keratomileusis ( LASIK) for high myopia. Methods The prospective study involved 80 patients (136 eyes) with high myopia who received LASIK treatment. They were divided into two groups according to preoperative diopters: Group A ( - 6. 00D ~ - 8. 00D, 93 eyes) and Group B ( > -8. 00D, 43 eyes). The visual acuity, refractive diopter, central corneal thickness, the ocular axis length, intraocular pressure and corneal curvature were collected at baseline, and 5 years after operation. Results Within the first 5 years after LASIK, the total incidence of regression was 16. 9% , while the regression incidences in the Group A and Group B were 11. 8% and 27. 9% , respectively, with significant difference between them (P <0. 05). The preoperative central corneal thickness of regressed eyes was lower than that of normal eyes, as the thickness difference between pre -and post - operation was correlated with the onset of regression. Furthermore, the ocular axis length of regression eyes was longer than that of normal eyes pre - or post - operation, though between them, there was no significant difference in the axis length difference between pre - and post - operation. There was no significant correlation between intraocular pressure or corneal curvature and onset of regression. Conclusion The preoperative refraction and the central corneal thickness difference were correlated with the refractive regression.关键词
