The prevention of aphakic retinal detachment by cryotherapy is controversial. No study up to now has compared results. We performed a retrospective study of two groups of patients: both groups consisted of patients with mature cataract and certain risk factors for retinal detachment (myopia, previous retinal detachment in the eye in study or in the fellow eye etc.) in the first group (n = 299) circumferential cryopexy has been performed prior to cataract extraction while in the second group (n = 149) no prophylaxis has been done. Comparison between the two groups did not reveal any protection afforded by prior cryotherapy: despite the prophylactic cryotherapy, 7 patients (2.3%) in the first group developed a retinal detachment post cataract extraction; two patients (1.3%) in the second group developed a retinal detachment; both were high-risk patients. These results lead us to conclude that prophylactic treatment does not necessarily prevent this complication. The best prophylaxis appears to be careful regularly performed examination of the peripheral retina both pre- and post-operatively.
冷冻疗法预防无晶状体性视网膜脱离存在争议。目前尚无研究对结果进行比较。我们对两组患者进行了一项回顾性研究：两组均为患有成熟白内障且有视网膜脱离某些危险因素（近视、研究眼或对侧眼既往有视网膜脱离等）的患者。第一组（n = 299）在白内障摘除术前进行了环形冷冻治疗，而第二组（n = 149）未进行任何预防措施。两组之间的比较未显示出先前冷冻治疗有任何保护作用：尽管进行了预防性冷冻治疗，但第一组仍有7例患者（2.3%）在白内障摘除术后发生了视网膜脱离；第二组有2例患者（1.3%）发生了视网膜脱离；两者均为高危患者。这些结果使我们得出结论，预防性治疗不一定能预防这种并发症。最佳的预防措施似乎是在术前和术后定期仔细检查周边视网膜。
