透明角膜切口位置选择对白内障术后患者视功能生存质量的影响

Effects of different position of clear corneal incision of cataract surgery on visual function and quality of life

目的:探究透明角膜切口不同位置的选择对白内障手术后视功能和生活质量的影响。方法:选择2013-04/2014-04在我院接受透明角膜切口超声乳化白内障吸除人工晶状体植入治疗术的老年性白内障患者126例126眼。以数字法随机分为观察组和对照组各63例,其中观察组选择最大角膜屈光力子午线轴向做透明角膜切口,对照组透明角膜切口位于颞上方(左眼位于鼻上方)。对比两组患者术后的视功能(VF)和生活质量(QOL),并对裸眼视力进行统计。结果:观察组术后视功能与生活质量总分依次为80.3±5.63,80.9±0.79分,显著高于对照组(74.9±5.24,76.5±0.76分)。并且观察组术后裸眼视力患者总比例少于对照组,而≤1.0患者多于对照组,差异有统计学意义(P<0.05)。结论:在进行白内障手术选择角膜最大屈光力经线上的透明角膜作为切口能有效提高治疗效果,对患者视功能以及生活质量的改善更明显。

AIM： To study the effects of different position of clear corneal incision of cataract surgery on visual function and quality of life. METHODS： ln this study, 126 cases （126 eyes） in our hospital from April 2013 to April 2014 were selected, who were accepted the transparent corneal incision phacoemulsification and intraocular lens implantation in treatment of senile cataract patients. With digital method were divided into observation group and control group with 63 cases in each group, included the observation group selected the maximum refractive power of the cornea radial axial transparent angle incision, and the control group in the temporal clear corneal incision, compared the two groups of patients with postoperative visual function （ VF） and quality of life （ QOL） , and made statistics of uncorrected visual acuity. RESULTS： ln the observation group, postoperative visual function and the scores of quality of life were 80. 3±5. 63 and 80. 9±0. 79, was significantly higher than the control group （74. 9±5. 24） and （76. 5±0. 76）. And the postoperative uncorrected visual acuity of patients in the observation group was less than that of the control group, while ≤1. 0 of patients than that in the control group. There was statistically significantdifference （P〈0. 05）. CONCLUSION： Transparent cornea in cataract surgery to choose the largest cornea diopter longitude as incision can effectively improve the therapeutic effect, especially on the visual function of patients and to improve the quality of life.
