对比分析了44例(51眼)4~38岁的水平斜视患者术前、术后不同时期的角膜屈折力。斜视手术、尤其是儿童,在同一只眼行水平直肌后徒加缩短,手术后7周内角膜水平径线屈折力有变化,7周后这种变化恢复原状;而儿童在一只眼行水平直肌后徒和成人水平肌加强、减弱手术,对角膜屈折力无影响。本文还探讨了引起角膜屈折力变化的可能因素,并对术后验光配镜时间提出看法。
The corneal refractive power of 44 cases (51 eyes) 4 ~ 38 years old with horizontal strabismus before and after surgery were compared and analyzed. Strabismus surgery, especially in children, only shortened horizontal rectus muscles in the same eye and changed the refractive power at the corneal horizontal axis within 7 weeks after surgery. After 7 weeks, this change reverted to the original condition; while in one eye Horizontal rectus abductor and adult level muscle strengthening, weakened surgery, no effect on the corneal refractive power. This article also discusses the possible causes of changes in the refractive power of the cornea, and postoperative optometry glasses time put forward their views.
