Pseudoexfoliation is a ubiquitous syndrome of multifactorial origin affecting elderly people by increasing the risk of cataract and secondary glaucoma development. Despite modern techniques and technologies for cataract surgery, pseudoexfoliation syndrome represents a challenge for surgeons because of the increased weakness of the zonular apparatus and limited pupil dilation. Due to the inherent difficulties during surgery, the risk of vitreous loss in these patients is several times higher than in cataract patients without pseudoexfoliation. Using currently available surgical devices (ophthalmic viscosurgical device, iris retractors and ring dilators, capsular tension ring, etc.), the risk of intraoperative complications may be much reduced, allowing the surgeon to handle difficult cases with greater confidence and safety. This review analyzes the methodologic approach to the patient with zonular laxity with the aim of providing useful advices to limit the risks of intraoperative and postoperative complications. From the preoperative planning, to the intraoperative management of the small pupil and phacodonesis, and to the postoperative correction of capsule phimosis and intraocular lens dislocation, a step approach to the surgical management of pseudoexfoliation patients is illustrated.
假性剥脱是一种多因素起源的普遍综合征,通过增加白内障和继发性青光眼的发生风险影响老年人。尽管有现代白内障手术技术和设备,但由于悬韧带装置变弱加剧以及瞳孔扩张受限,假性剥脱综合征对外科医生来说仍是一项挑战。由于手术过程中存在固有困难,这些患者玻璃体丢失的风险比无假性剥脱的白内障患者高出数倍。使用目前可用的手术器械(眼科粘弹剂、虹膜牵开器和环形扩张器、囊袋张力环等),术中并发症的风险可能会大大降低,使外科医生能够更有信心和安全地处理困难病例。本综述分析了针对悬韧带松弛患者的方法学途径,旨在提供有用建议以限制术中及术后并发症的风险。从术前规划,到小瞳孔和晶状体震颤的术中处理,再到术后囊膜挛缩和人工晶状体脱位的矫正,阐述了假性剥脱患者手术管理的分步方法。
