【摘要】：目的观察分析双眼白内障超声乳化人工晶状体植入手术患者主视眼的转变及对视觉质量的影响。方法选取符合入选标准的双眼行白内障手术患者46例,年龄(65.8±1.3)岁。按术前屈光度分为:A组(27例),双眼等效球镜度数差异2D;B组(19例),双眼等效球镜度数差异≥2D。所有患者均行术前及术后3个月屈光度检查,使用盲法行术前及术后1、3个月主视眼测量检查,术后3个月行对比敏感度检查和视觉满意度问卷调查。结果术后1个月13例(28.3%)发生主视眼转变,A组9例,转变率33.3%,B组4例,转变率21.1%,2组间转变率差异无统计学意义(P0.05)。术后3个月11例(23.9%)患者发生主视眼转变,A组7例,转变率25.9%,B组4例,转变率为21.1%,主视眼转变率组间差异无统计学意义(P0.05)。术前主视眼较非主视眼近视屈光度低(P=0.01),术后主视眼与非主视眼屈光度差异无统计学意义(P0.05)。术后主视眼发生转变与未发生转变的患者对比敏感度及视觉满意度问卷调查差异均无统计学意义(P0.05)。结论白内障术后存在主视眼转变,但主视眼转变对视觉质量无影响。不同程度的屈光参差患者白内障术后主视眼转变无明显差异。
[Abstract]:Objective to observe the change of main eye and its influence on visual quality in patients undergoing phacoemulsification and intraocular lens implantation. Methods 46 binocular cataract patients, aged (65.8 卤1.3) years, were selected. According to the preoperative diopter, the patients were divided into two groups: group A (n = 27), group B (n = 19) with binocular equivalent spherical degree, and group B (n = 19) with Binocular equivalent degree 鈮，
