Clinical Analysis of Laser in Situ Keratomileusis for Compound Myopic Astigmatism

Objective: To evaluate the efficacy and predictability of LASIK for correcting compound myopic astigmatism. Methods: One hundred and ten eyes in 60patients with compound myopic astigmatism had been corrected with LASIK.All were followed up more than 12months.Meanwhile,all eyes were divided into two groups according to the preoperative astigmatism:Group A(-2 25～-3 00D),Group B(-3 25～-6 00D). Resutls: In group A: the average refractive cylinder was (-2 51±0.68)D preoperation,and had the average of (-0 5±0 25)D residual astegmatism postoperation. In group B: the average refractive cylinder was -3 25～-6 00 D preoperation,and had the average of (-0 5±0 22)D residual astigmatism postoperation. There was no statistical difference in astigmatism between the two groups after 12 months.In A and B groups the visual acuity after operation was better than the corrected visual acuity before operation. Conclusion: For higher myopic with moderate and higher astigmatism LASIK can provide better accuracy and predictability.
