Pediatric cataract surgery has seen several advances in techniques, technologies, and conceptual practices. Pediatric cataract management heavily depends on a combined effort, not only from the ophthalmologist, but also the parents, the anesthetists, and the supporting staff members (eg, optometrists, orthoptists, patient coordinators). Surgical management, though critical, is not the only consideration for these children. Continuing visual rehabilitation and monitoring for complications remain key elements even after the surgery is done. Pediatric cataract surgery is a complex issue best left to surgeons who are familiar with the surgical paradigms and its long-term complications. Key components of surgery are management of posterior capsule and anterior vitreous and intraocular lens (IOL) implantation. It is a preferred practice today to perform a primary posterior capsulorhexis with anterior vitrectomy in younger children (up to 3 to 5 years old). Even in older children (up to the age of 8 years), performing a posterior capsulorhexis without anterior vitrectomy is the preferred approach. Above the age of 8 years, the posterior capsule can be left intact. In-the-bag IOL implantation is almost becoming a norm for children above the age of 1 year. Though there is no universal consensus regarding the earliest age for primary IOL implantation, many surgeons increasingly prefer primary IOL implantation even in infants. Alternate approaches that can avoid anterior vitrectomy like optic capture through the posterior capsulorhexis and bag-in-the-lens are also gaining more and more popularity.
小儿白内障手术在技术、工艺和概念实践方面取得了多项进展。小儿白内障的治疗很大程度上依赖于多方共同努力,不仅需要眼科医生,还需要家长、麻醉师以及辅助工作人员(如验光师、视光师、患者协调员)。手术治疗固然关键,但对于这些患儿来说并非唯一需要考虑的因素。即使手术完成后,持续的视觉康复和并发症监测仍是关键环节。小儿白内障手术是一个复杂的问题,最好由熟悉手术模式及其长期并发症的外科医生来处理。手术的关键组成部分是后囊膜和前部玻璃体的处理以及人工晶状体(IOL)植入。如今,对于年幼儿童(3至5岁以下),首选在进行前部玻璃体切割术的同时行一期后囊膜撕开术。即使对于年龄较大的儿童(8岁以下),不进行前部玻璃体切割术而行后囊膜撕开术也是首选方法。8岁以上,后囊膜可保持完整。对于1岁以上儿童,囊袋内人工晶状体植入几乎已成为常规做法。尽管对于一期人工晶状体植入的最早年龄尚无普遍共识,但许多外科医生甚至越来越倾向于在婴儿期就进行一期人工晶状体植入。通过后囊膜撕开术进行光学捕获和晶状体囊袋内植入等可避免前部玻璃体切割术的替代方法也越来越受欢迎。
