框镜与角膜接触镜矫正对人眼光学性能的影响比较

Contrast observation of the effect of frame mirror and corneal contact lens correction on the optical properties of the human eye

目的 比较框镜与角膜接触镜矫正对人眼光学性能的影响.方法 选择2014年9月-2015年9月宁波市眼科医院收治需行视力矫正的120例近视眼患者,随机分为对照组和观察组,各60例.对照组佩戴框镜,观察组佩戴角膜接触镜,比较2组人眼光学性能.结果 观察组矫正视力与对照组对比差异无统计学意义;2组中心凹屈光值对比差异无统计学意义;2组中心凹屈光值对比差异无统计学意义;观察组T30°周边屈光度为（1.00±0.21）D、N30°周边屈光度为（0.34±0.08）D,均显著低于对照组（P〈0.05）.观察组舒适度良好率显著高于对照组,角膜并发症发生率显著低于对照组（P〈0.05）.结论 采用框镜与角膜接触镜均可良好矫正视力,其中角膜接触镜矫正周边远视性离焦具有的一定优势,能够有效减少周边远视性离焦量,延缓近视,进而提高舒适安全性.

Objective To explore the effect of the contrast frame mirror and the corneal contact lens correction on the optical properties of the human eye.Methods120 cases of myopia patients from 2014 September to September 2015 in our hospital for vision correction were randomly divided into two groups： control group, observation group wearing frame mirror, wearing contact lens, the optical properties of the eye were compared between the two groups.ResultsThe corrected visual acuity of observation group hadno significant difference compared with the control group;no significant difference in the values of refractive foveal contrast;foveal refractive value contrast in the two groups had no statistical difference;the observation group T30 degrees for peripheral refraction was （1.00±0.21） D, N30°peripheralrefraction was （0.34±0.08） D,were significantly lower than the control group （P〈0.05）.The good rate of observation group was significantly higher than the control group, the incidence of corneal complications was significantly lower than that of the control group （P〈0.05）.ConclusionThe frame and the corneal contact lens can be well corrected visual acuity, the corneal contact lens for the correction of certain peripheral hyperopic defocus has advantages, can effectively reduce the peripheral hyperopic defocus, delaying myopia, and improve the comfort and safety.
