Clnical analysis of laser in situ keratomileusis for compound myopic astigmatism / 中国基层医药

ABSTRACT

Objective To evaluate the curative effect of LASIK for correcting compound myopic astigmatism.Methods One hundred and sixteen eyes in 68 patients with compound myopic astigmatism had been corrected with LASIK.All patients were followed up for more than 12 months.Meanwhile,all eyes were divided into two groups according to the preoperative astigmatismgroup I (-2.25～ -3.00D),group Ⅱ (-3.2.5～ -6.00D).Results In group Ithe average refractive cylinder was (- 2.51±0.68) D preoperafion, and had the average of (- 0.51±0.25) D residual astegmatism postoperation.In group Ⅱthe average refractive cylinder was (- 3.85±0.46) D preoperation, and had the average of (- 0.52±0.22)D residual astigmatism postoperation.There was no statistical difference in astigmatism between the two groups after 12 months.In group Ⅰ and Ⅱ the visual acuity after operation was better than the corrected visual acuity before operation.Conclusion For compound myopic astigmatism LASIK was safe and effective.
