A major concern in pediatric intraocular lens implantation surgery is the high incidence of posterior capsule opacification. The purpose of this article is to investigate a surgical technique for maintaining a clear visual axis after pediatric cataract and intraocular lens surgery.
In a prospective evaluation, posterior capsulorhexis with optic capture as a surgical technique for preventing secondary membrane formation after pediatric cataract extraction is investigated. This technique involves capture of an intraocular lens optic through a posterior curvilinear capsulorhexis opening. Perioperative complications and incidence of secondary cataract are presented. Results will be compared to an historic cohort of patients with pediatric cataract-intraocular lens who did not have posterior continuous curvilinear capsulorhexis with optic capture.
In 13 consecutive eyes operated on in children aged 2 to 12 years (mean, 5.8 years), there was no opacification of the visual axis at a mean follow-up of 19 months after surgery (range, 8-30 years).
Posterior capsulorhexis with optic capture holds promise as a technique for preventing secondary membrane formation. This maneuver ensures centration of the posterior chamber intraocular lens while eliminating the need for an anterior vitrectomy. Apposition of the anterior and posterior capsule leaflets anterior to the optic may limit the migration of Elschnig pearls, reducing the incidence of secondary membranes and the need for additional procedures.
小儿人工晶状体植入手术中的一个主要问题是后囊膜混浊的发生率很高。本文的目的是研究一种在小儿白内障和人工晶状体手术后保持视轴清晰的手术技术。
在一项前瞻性评估中，研究了以光学捕获后囊连续环形撕囊作为预防小儿白内障摘除术后继发性膜形成的手术技术。该技术包括通过后囊连续环形撕囊开口捕获人工晶状体光学部。介绍了围手术期并发症和继发性白内障的发生率。结果将与一组未进行光学捕获后囊连续环形撕囊的小儿白内障人工晶状体植入患者的历史队列进行比较。
在13例年龄为2至12岁（平均5.8岁）儿童的连续手术眼中，术后平均随访19个月（范围8至30个月）时视轴未出现混浊。
光学捕获后囊连续环形撕囊作为一种预防继发性膜形成的技术具有前景。该操作可确保后房型人工晶状体居中，同时无需进行前部玻璃体切除术。在光学部前方使前后囊瓣贴合可能会限制Elschnig珠的迁移，降低继发性膜的发生率以及额外手术的必要性。
