摘要 目的比较角巩膜隧道切口及透明角膜切口白内障超声乳化术对患者角膜散光的影响。方法单纯白内障患者88例(122眼)。按切开入路不同随机分为两组:透明角膜组(A组):40例(60眼);角巩膜隧道组(B组):48例(62眼),观察术前、术后1天、1周、1个月时平均角膜散光度手术源性散光、视力、及最佳矫正视力的情况,并进行统计学分析。结果A.B两组:术后1天、1周、1月平均角膜散光度比较的差异均有统计学意义(P〈0.05);术后1天、1周SIA值差异有统计学意义(P〈0.05),术后1月SIA值比较的差异无统计学意义(P〉0.05);术后1天、1周裸眼视力≥0.5及最佳矫正视力≥0.8比较的差异均有统计学意义(P〈0.05),术后1月两组之间比较的差异无统计学意义(P〉0.05)。结论角巩膜隧道切口白内障超声乳化摘除联合人工晶体植入术对角膜散光改变较小。 Objective To study the change of corneal astigmatism after phacoemulsification through different incision. Methods 88 cases(122 eyes) were randomly divided into two groups. 40 cases(60 eyes) underwent clarity corneal incision in group A,and 48 cases (62 eyes) through sclera tunnel incision in group B. Mean corneal astigmatism, surgically induced astigmatism, uncorrected Visual acuity(UCVA) and best correct vision acuity(BCVA) ,were recorded in pre-and post-operation (1d, 1w, 1 m). Results The Mean astigmatism show significant statiatic difference in all postoperation stages (P〈0.05) ;The SIA 1 days and 1 weeks was significant different in 1d and1w after operation (P〈0. 05) ,the 1 m outcomes P〉0.05. UCVA ≥0.5 and BCVA≥0.8 of 1 d and 1 w after operation had significant difference(P〈0.05) ,while the lm had no significant difference(P〉0.05). Conclusion The sclera tunnel incision cause less adverse effects on corneal astigmatism.
