Myopic patients, in particular, should be carefully observed by contactglass examination prior to and after cataract surgery, in order to be able to perform prophylactic photocoagulation. In cases of vitreous loss, the risk of having an aphakic retinal detachment will be 20 times as high; that is to say, in one of every five cases cataract extraction with vitreous loss can be expected to produce a retinal detachment. It can be said, therefore, that the best cataract procedure- as far as aphakic retinal detachment is concerned-will be that in which we can expect the lowest rate of vitreous loss. Whether an extensive anterior vitrectomy will reduce the number of aphakic detachments, we cannot yet say defintely, because in these cases we have only routinely performed vitrectomy during the past 2 years.
特别是近视患者,在白内障手术前后应通过接触镜检查仔细观察,以便能够进行预防性光凝治疗。在发生玻璃体丢失的情况下,无晶状体性视网膜脱离的风险将高出20倍;也就是说,每五例玻璃体丢失的白内障摘除病例中,预计有一例会发生视网膜脱离。因此可以说,就无晶状体性视网膜脱离而言,最佳的白内障手术方法将是玻璃体丢失率最低的方法。至于广泛的前部玻璃体切除术是否会减少无晶状体性视网膜脱离的数量,我们目前还不能肯定地说,因为在过去两年中,我们仅在这些病例中常规进行了玻璃体切除术。
