摘要

既往角膜屈光手术病例的白内障手术可能是眼科医生的一个主要挑战。这种病例的屈光预后应在术前计划过程中特别注意,应针对既往屈光手术类型进行调整:在皮瓣下或角膜表面上切开,消融。这些病例白内障手术后屈光不满意的避免主要取决于眼内晶体计算的精度以及每例病例适当生物统计公式的选择。白内障手术的现代技术可帮助外科医生把白内障手术作为屈光不正病例无需屈光手术的一个目标前进。我们为白内障外科医生治疗这些挑战性病例提供实用指南。

Cataract surgery in cases with previous corneal refractive surgery may be a major challenge for the ophthalmologist. The refractive outcome of the case deserves special attention in the preoperative planning process, which should be tailored for the type of prior refractive procedure: incisional, ablative under a flap, or on the corneal surface. Avoiding refractive surprise after cataract surgery in these cases is principally dependent on the accuracy of the intraocular lens calculation, together with the selection of the appropriate biometric formula for each case. Modern techniques for cataract surgery help surgeons to move toward the goal of cataract surgery as a refractive procedure free from refractive error. We give practical guidelines for the cataract surgeon in the management of these challenging cases.
