Cataract facoemulsification with continuous anterior capsulorhexis and foldable intraocular lens implantation into the capsular bag has become basic, standard method in cataract surgery and curvilinear capsulorhexis s the most common technique for opening the anterior lens capsule. The opening, made during the operation, within several months of postoperative evolution gradually constricts and in extreme cases it may even close completely. That course of healing is not desirable because of evoking a noted impairment of vision. Decreasing in the anterior capsule opening is observed mostly in eyes with weakened lens zonules. It happens in high myopia, retinitis pigmentosa, diabetes mellitus, retinopathia diabetica, pseudoexfoliation syndrome, uveitis and people of well advanced age. Inspired by observation of a particular, quite drastic case of capsule contraction syndrome, we attempted to analyze the causes, pathogenesis, risk factors, clinical course, prevention and treatment of options for that syndrome.
白内障超声乳化联合连续环形撕囊及可折叠人工晶状体植入囊袋内已成为白内障手术的基本标准方法,而曲线形撕囊是打开晶状体前囊的最常用技术。手术中形成的开口在术后几个月的演变过程中会逐渐收缩,在极端情况下甚至可能完全闭合。由于会引起明显的视力损害,这种愈合过程是不理想的。前囊开口缩小主要见于晶状体悬韧带薄弱的眼睛。发生在高度近视、色素性视网膜炎、糖尿病、糖尿病视网膜病变、假性剥脱综合征、葡萄膜炎以及高龄人群中。受一例特别严重的囊袋收缩综合征病例观察的启发,我们试图分析该综合征的病因、发病机制、危险因素、临床过程、预防措施及治疗选择。
