非球面衍射型多焦人工晶状体临床应用观察

Clinical observation of the effects of Acrysoft IQ ReSTOR +3D IOL

目的观察非球面衍射型多焦人工晶状体(Acrysoft IQ ReSTOR+3D IOL)的临床效果。方法2011年10月至2012年10月间,白内障超声乳化吸除Acrysoft IQ ReSTOR+3 D IOL植入患者在排除影响术后视力的因素共55例(83只眼)作为观察组,并在观察组标准基础上选取同期植入Alcon Acrsoft SN60AT IOL 33例(42只眼)作为对照组。观察患者术后反应、主观感觉、远、近视力、对比敏感度(CS),随访时间均在6个月以上。结果二组术后反应基本相同,视觉异常出现率ReSTOR组在术后2周高于对照组(P<0.05),术后1个月、6个月差异无显著性(P>0.05),术后1个月、6个月观察组裸眼远视力≥0.6者为96.39%、96.00%,≥1.0者为45.78%、46.67%,与对照组比较无明显差异(P>0.05)。术后1个月、6个月观察组裸眼近视力≥0.6者为96.39%、97.33%,≥1.0者为21.69%、22.67%,明显优于对照组6.25%、7.14%、0%、0%(P<0.001)。在术后1个月和6个月时,对照组在各空间频率均高于观察组。仅高空间频率(18 c.d-1),1个月时观察组CS值明显低于对照组,2组之间差异有统计学意义(P<0.05)。观察组CS随时间延长而提高,1个月和6个月之间差异有统计学意义(P<0.05)。结论非球面衍射型多焦人工晶状体(Acrysoft IQ ReSTOR+3D IOL)可为患者提供良好的裸眼远、近视力,术后视觉异常出现率低。

Objective ToobservetheeffectsdAcrysdtIQReSTOR ＋3DIOL. Methods All patients were di- vided into two groups： Aerysdt IQ ReSTOR ＋ 3D IOL group recruited 55 patients （ 83 eyes ） eyes that received phacoemul- sitication and were implanted with Acrysoft IQ ReSTOR ＋ 3D IOL from October 2011 to October 2012. Another 33 patients （42 eyes） received phacoemulsification and were implanted with A]con Acrsoft SN60AT IOL served as a control/8nmp. Postoperative subjective visual functlonality, distant and near visual acuifies, and contrast sensitivity （ CS ） were followed up for at least 6 mceths and were analyzed. Results Subjective visual functionality and uncorrected distant visual acuilies were not diffexent between the two groups （ P 〉 0. 05 ） at 1 month and 6 months after the treatment. Uncorrected near visu- al acuities were markedly improved in patients implanted with Acrysoft IQ ReSTOR ＋ 3D IOL. By 1 month and 6 months, contrast sensitivity was better in Acrysdt IQ ReSTOR ＋ 3D IOL group at all spatial frequencies. The only exception was at 1 month CS at high upatlal frequency （ 18 c/d） was lower in cizervafional group. CS tended to improve with time in pa- tients implanted with Acrysoft IQ ReSTOR ＋ 3D IOL, with a sign/ficantly better CS at 6 month than at 1 month （ P 〈 0. 05 ）. Conclusion Acrysoft IQ ReSTOB ＋ 3D IOL can provide a high level outcomes in both distant and near uncorrected visions with low incidence of visual symptoms
