Abstract

Retinal surgery can induce significant refractive errors. These errors include spherical changes caused by alterations in axial length after scleral buckle placement, astigmatic changes induced by a scleral buckle or pars plana vitrectomy, and focal alterations in corneal curvature that can significantly limit postoperative visual acuity. The adjunctive use of silicone oil can impose alterations directly, by the oil's interaction with the other refractive elements of the eye, and indirectly, through its effects on intraocular lens power calculations for subsequent cataract surgery.

摘要

视网膜手术可导致显著的屈光不正。这些误差包括巩膜扣带放置后眼轴长度改变引起的球镜变化、巩膜扣带或玻璃体切割术引起的散光变化，以及角膜曲率的局部改变，这些改变可显著限制术后视力。硅油的辅助使用可直接通过其与眼内其他屈光元件的相互作用，以及间接通过其对后续白内障手术人工晶状体屈光度计算的影响来引起改变。
