目的:观察白内障超声乳化及非超声乳化小切口摘出人工晶状体植入术后糖尿病视网膜病变(DR)的光凝治疗效果，进一步探讨光凝治疗的时机及影响光凝的因素。 方法:对60例108 眼行超声乳化或非超声乳化小切口白内障摘出人工晶状体植入术后的糖尿病视网膜病变患者在眼底荧光血管造影(FFA)指导下根据DR分期，早期予局限性视网膜光凝、格栅样光凝或标准全视网膜光凝治疗。 结果:术后随诊1a，所有患者视力提高30眼(27.8%),视力不变71眼(65.7%),视力下降7眼(6.5%)，光凝术后FFA随访检查显示，视网膜水肿消退，新生血管大部分萎缩，出血、渗出部分吸收，18例合并有黄斑水肿眼光凝术后完全消退。 结论:白内障术后合理及时的进行氩激光视网膜光凝治疗，能有效控制糖尿病视网膜病变的进展，对于改善糖尿病视网膜病变的视功能，稳定视力有重要作用。

AIM:To observe photocoagulation treatment effect on diabetic retinopathy (DR) after phacoemulsification or non-phacoemulsification small incision cataract extraction and intraocular lens implantation, to further explore the timing and influencing factors of photocoagulation treatment. METHODS:Totally 60 cases (108 eyes) with DR after phacoemulsification or non-phacoemulsification small incision cataract extraction and intraocular lens implantation underwent local retinal photocoagulation, grid photocoagulation or standard panretinal photocoagulation treatment at early stage according to DR staging under the guidance of fundus fluorescein angiography (FFA). RESULTS:After 1 year follow-up, visual acuity improved in 30 cases of all patients (27.8%), unchanged in 71 eyes(65.7%), decreased in 7 eyes(6.5%).FFA follow-up examination showed retinal edema vanished, most neovascularization shrinked, bleeding and exudation partly absorbed,the complicated macular edema in 18 cases completely vanished after photocoagulation. CONCLUSION: Reasonable and timely conduct of argon laser retinal photocoagulation therapy after cataract surgery can effectively control the progress of DR,and plays an important role in the improvement of visual function and stabilization of vision.
