Clear lens extraction is a surgical procedure to correct high axial myopia. The authors explain how this technique may lead to serious vitreoretinal complications.
The study included 41 eyes of 39 patients aged 25 to 58 years (mean, 37.5 years) with high axial myopia (14-29 diopters; mean, 19.5 diopters) operated on for retinal detachment after clear lens extraction. Retinal detachment occurred 1 month to 4 years after lens extraction, except for two eyes that also had intraoperative choroidal hemorrhages.
Twenty-six of the 41 eyes had undergone 360 degree prophylactic retinopexy on preequatorial areas; in four eyes, the retinal breaks occurred along the edge of the prior circumferential photocoagulation. Seventeen eyes exhibited proliferative vitreoretinopathy of various grades. The retina was reattached in 36 eyes. Only nine eyes achieved final visual acuity of 20/60 or better.
Although the authors do not report the actual incidence of retinal detachment after clear lens extraction, they indicate that potentially blinding complications can occur after this surgical procedure, despite prophylactic treatments.
透明晶状体摘除术是一种矫正高度轴性近视的手术方法。作者解释了该技术如何导致严重的玻璃体视网膜并发症。
本研究纳入了39例年龄在25至58岁（平均37.5岁）的高度轴性近视患者（14 - 29屈光度；平均19.5屈光度）的41只眼，这些患者在透明晶状体摘除术后因视网膜脱离接受手术。除了两只术中发生脉络膜出血的眼睛外，视网膜脱离发生在晶状体摘除术后1个月至4年。
41只眼中的26只眼在赤道前区域进行了360度预防性视网膜光凝；4只眼中，视网膜裂孔沿先前环形光凝边缘出现。17只眼表现出不同程度的增殖性玻璃体视网膜病变。36只眼的视网膜重新复位。只有9只眼最终视力达到20/60或更好。
尽管作者未报告透明晶状体摘除术后视网膜脱离的实际发生率，但他们指出，尽管进行了预防性治疗，该手术仍可能发生导致失明的并发症。
