目的 观察老年性白内障患者植入黄色非球面人工晶状体AcrySof IQ术后对比敏感度和眩光敏感度.方法 前瞻性临床对照研究.56例(56只眼)老年性白内障患者,随机分为三组,分别植入非球面人工晶状体AerySof IQ(SN60wF)及球面人工晶状体Acrysof Natural(SN60AT)、Acrysof (SA60AT).术后2月行最佳矫正视力、像差及对比敏感度检查.结果 三组患者术后最佳矫正视力≥20/30.IQ组与球面晶状体组比较,球差均显著性减少(P<0.05),高阶像差及彗差无统计学意义(P0.05).在非眩光状态下,低频时IQ组的对比敏感度(10g值)显著高于球面晶状体组(P<0.05),中频2.5deg时IQ组的对比敏感度显著高于SA60AT组(P<0.05).在眩光状态下,低频时IQ组的对比敏感度也显著高于球面晶状体组(SN60AT组:P<0.01,SA60AT组:6.3degrees P<0.01,4.0degrees P<0.05).结论 非球面人工晶状体可以减少球面像差,提高低频尤其是眩光状态下的对比敏感度从而获得更好的视觉质量.滤蓝光晶状体与普通晶状体比较对比敏感度差异无统计学意义,不能明显改善视功能.

Objective To compare contrast sensitivity and glare sensitivity in pseudophakic eyes with a yellow-tinted aspherical intraocular lens (IOL) and conventional spherical IOL. Methods Fifty six patients who had phacoemulsification in a prospective trial were randomized to receive an AcrySof IQ SN60WF IOL,AcrySof Natural SN60AT IOL,or AcrySof SA60AT IOL. At 2 months postoperatively,best corrected visual acuity,high-order aberration and contrast sensitivity were examined. Results All of the eyes had best correct-ed visual acuity (BCVA) 20/30. The AerySof IQ IOL showed statistically significant less induction of spheri-cal aberration (P <0.05 ) when compared with the AerySof Natoral IOL and AcrySof SA60AT IOL,but had no difference in high-order aberration and coma (P 0.05 ). Without glare, the AcrySof IQ group had significantly higher contrast sensitivity at 6.3 degrees,4.0 degrees, 2.5 degrees compared to SA60AT group (P <0.05 ); and had significantly higher contrast sensitivity at 6.3 degrees,4.0 degrees compared to SN60AT group (P <0.05 ).With glare, the AerySof IQ group had significantly higher glare sensitivity at 6.3 degrees,4.0 degrees ( SN60AT group: P<0.01 ,SA60AT group: 6.3 degrees P<0.01,4.0 degrees P<0.05). Conclusion Implantation of an a-spherical IOL resulted in reduced ocular spherical aberration and improved contrast sensitivity and led to better subjective quality of vision. The yellow-tinted IOL has similar spherical aberration and contrast sensitivity with standard IOL, and so has similar vision performance.
