简介：目的评价小切口白内障囊外摘除人工晶状体植入联合小梁切除术治疗急性闭角型青光眼合并白内障患者的安全性和有效性.方法对29例（29眼）急性闭角型青光合并白内障患者,在眼压控制正常、稳定,皮质类固醇局部抗炎,葡萄膜炎症得到显著控制后,行小切口白内障囊外摘除人工晶状体植入联合小梁切除术,术后随访6～12个月.结果术后眼压正常,视功能较术前有不同程度的改善.术中并发症有剪除周边虹膜时少量出血,术后并发症有角膜水肿（后弹力层皱褶）、葡萄膜炎、人工晶状体表面渗出膜等,无暴发性脉络膜出血、前房延缓形成、角膜失代偿、睫状环阻滞性青光眼等并发症发生.结论急性闭角型青光眼合并白内障患者,在眼压正常、葡萄膜炎症控制后,行小切口白内障囊外摘除人工晶体植入联合小梁切除术,对控制患眼眼压,减少术后前房延缓形成,角膜失代偿等并发症的发生,以及不同程度的保护和恢复视功能方面有积极的意义和较好的临床效果.本手术是安全和有效的,且费用低廉,尤其适合基层开展.

简介：目的：探讨手法小切口联合负度数人工晶状体植入术治疗白内障合并超高度近视眼的临床疗效。方法：对因白内障合并超高度近视眼行小切口联合负度数人工晶状体植入术的75例98眼患者进行回顾性研究,记录术前眼轴长度和术后视力、屈光度数及其与预期屈光度数的偏差值（屈光度数偏差值）,观察手术并发症和术后眼部情况。术后随访6～12mo。结果：术前平均眼轴长度为32.05±1.78mm。术后最佳矫正视力≥0.2者66眼（67.3%）;≥0.5者43眼（43.9%）,术后屈光度数偏差值〈±1.00D者48眼（49.0%）;〈±2.00D者78眼（79.6%）。术中后囊膜破裂3眼。术中出现后弹力层部分脱离1例。术后角膜不同程度水肿21眼。术后6mo有13眼出现后囊混浊,经Nd：YAG激光切开后视力恢复。未见发现视网膜脱离、继发性青光眼、黄斑囊样水肿、人工晶状体移位等并发症。术后2眼出现双眼干扰症状,经过3mo后行另一眼人工晶状体植入术,术后症状消除。结论：手法小切口白内障摘除负度数人工晶状体植入术是治疗白内障合并超高度近视眼安全、有效的方法。
