摘要
目的探讨角膜接触锐对眼屈光的影响。方法利用SEED自动电脑验光仪观察测定160名（320眼）近视患者戴软性及送气性硬性角膜接触镜一年之中角膜屈率半径、角膜激光度及眼球镜度的变化。结果戴软性角膜接触镜一年后，眼屈光状态与裁镜前比较，无显著性变化。戴透气性硬性角膜接触镜一年后，眼屈光状态与戴镜前比较，有显著性变化；角膜曲车半径值平均增加0．12mm（P＜0．0005），角膜散光度平均降低0．65D（P＜0．0005），眼球镜度近视降低0．49D（0．005＜P＜0．01）。结论由此推断透气性硬性角膜接触锐对近视、散光有一定防治效果。
To investigate the innuence on ocular refraction of wearing contact lenses. Method The changes of the corneal curvature, astigmatism and ocular spherical refraction of l6o patients with myopia(320 eyes), wearing soft contact Ienses and rigid gas permealbe contact lenses for one year were measured by using SEED Auto REF - KERATOMETER. Results The results reveals that there are no significant changes in the ocular refraction after wearing soft contact lenses. There are significant changes in the ocular refraction after wearing rigid gas permeable contact lenses. After rigid gas permeable contact lenses were worn for one year, the mean radius of corneal curvature in creased 0. 12mm(P < 0. 0005 ); the mean corneal astigmatism degree decreased 0. 65D(P < 0. 005); the mean ocular spherical refraction degree decreased 0.49D (0.005 < P <0.01 ). Conclusion It can be concluded that myopia and astigmatism can be prevented and cured by wearing rigid gas permeable contact lenses.
