摘要
目的:探讨准分子激光非穿透小梁切除术对角膜屈光的影响。方法:将我科近6年收治的开角型青光眼患者82例(154眼),按随机原则分为准分子激光非穿透小梁切除术(A组78眼),非穿透小梁切除术(B组76眼)。在术前1天、术后1天、1周、1月和3月进行视力、眼压、角膜地形图检查。结果:A、B组术前散光分别为(0.51±0.27)D、(0.52±0.31)D。术后1天、1周、1月和3月,A组的散光分别为(0.74±0.31)D、(0.69±0.29)D、(0.61±0.27)D、(0.54±0.26)D;B组分别为(1.11±0.33)D、(1.02±0.30)D、(0.89±0.31)D、(0.78±0.28)D。术后各阶段散光均高于术前。A组的散光较B组低(P<0.05)。术后第一天散光最大,以后逐渐减小。术后1天、1周、1月和3月,A组的SIA分别为(0.69±0.51)D、(0.64±0.40)D、(0.65±0.38)D、(0.59±0.33);B组的SIA分别为(1.19±0.74)D、(1.08±0.60)D、(0.87±0.49)D、(0.77±0.40);术后1天,A组SIA较B组小(P<0.05);两组SIA均随时间推移而减小,但A组SIA始终小于B组。结论:准分子激光非穿透小梁切除术对角膜屈光的影响小于非穿透小梁切除术,术后早期视力恢复好。
Objective:To observe effect on corneal refraction after primary open angle glaucoma treated by excimer laser non-penetrating trabeculectomy.Methods:Eighty-two patients(154 eyes)of primary open angle glaucoma in the past six years,according to the randomized principle they were divided into excimer laser non-penetrating trabeculectomy(A)and non-penetrating trabeculectomy(B).The visual acuity,IOP,corneal topography were observed 1day,l week,1 month and 3 months after surgery.Results:After surgery,the astigmat...
