To assess risk factors and incidence of retinal complications after cataract extraction in patients with high myopia.
Retrospective, noncomparative case series.
One hundred eighteen patients with highly myopic eyes who had an axial length of 26 mm or more (mean axial length, 30.13 +/- 2.08 mm) and who underwent cataract surgery over a period of 6 years were studied.
Patients underwent cataract extraction either by extracapsular cataract extraction (ECCE) or phacoemulsification. Prophylactic argon laser photocoagulation was performed in 13 eyes for retinal tears recognized before surgery and in 13 eyes after surgery; neodymium:YAG (Nd:YAG) laser capsulotomy was performed for patients with posterior capsule opacification (PCO) that affected the vision.
Incidence of retinal detachment and PCO and percentage of prophylactic argon laser or of Nd:YAG laser treatments.
Of the 118 eyes, 73 (61.9%) underwent ECCE and 45 (38.1%) underwent phacoemulsification. Posterior capsule opacification was the most common complication and was found in 30 eyes (25.4%). Thirteen patients (11%) received prophylactic laser treatment for retinal tears before cataract operation, and 13 more patients (11%) had postoperative retinal tears requiring laser treatments. None of these patients developed retinal detachment. Two patients (1.69%) developed retinal detachment within 6 months after their operations. There were no intraoperative complications, and postoperative Nd:YAG capsulotomy was not performed in these two patients.
Active searching and prophylactic laser treatments for retinal tears developed before and after cataract extraction in patients with high myopia are recommended. This may lower the incidence of postoperative retinal detachment.
评估高度近视患者白内障摘除术后视网膜并发症的危险因素及发生率。
回顾性、非对照病例系列研究。
对118例高度近视眼患者进行研究,这些患者眼轴长度为26mm或更长(平均眼轴长度为30.13±2.08mm),并在6年期间接受了白内障手术。
患者接受白内障囊外摘除术(ECCE)或超声乳化白内障吸除术。对术前发现的13只眼和术后13只眼的视网膜裂孔进行预防性氩激光光凝;对影响视力的后囊膜混浊(PCO)患者进行钕:钇铝石榴石(Nd:YAG)激光后囊切开术。
视网膜脱离和PCO的发生率以及预防性氩激光或Nd:YAG激光治疗的百分比。
118只眼中,73只眼(61.9%)接受了ECCE,45只眼(38.1%)接受了超声乳化白内障吸除术。后囊膜混浊是最常见的并发症,在30只眼中发现(25.4%)。13例患者(11%)在白内障手术前接受了视网膜裂孔的预防性激光治疗,另外13例患者(11%)术后视网膜裂孔需要激光治疗。这些患者均未发生视网膜脱离。2例患者(1.69%)在术后6个月内发生视网膜脱离。术中无并发症,这2例患者未进行术后Nd:YAG后囊切开术。
建议对高度近视患者白内障摘除术前和术后出现的视网膜裂孔进行积极检查和预防性激光治疗。这可能会降低术后视网膜脱离的发生率。
