Abstract

PURPOSE

To evaluate the modulation-transfer function (MTF) in eyes implanted with a conventional intraocular lens (IOL) and 2 IOLs designed for microincision cataract surgery (MICS).

SETTING

Research, Development, and Innovation Department, Instituto Oftalmológico de Alicante, Alicante, Spain.

METHODS

This prospective nonrandomized consecutive series comprised 30 eyes implanted with 1 of the following IOLs: conventional acrylic foldable (AcrySof MA60BM, Alcon Laboratories) or the UltraChoice 1.0 ThinOptX (ThinOptX Inc.) or the Acri. Smart 48S (Acri.Tech) MICS IOL. The 0.5 MTF and 0.1 MTF following MICS were calculated 3 months after implantation with the Optical Quality Analysis System (OQAS) for a 5 mm pupil. The differences were statistically analyzed with the Mann-Whitney U test.

RESULTS

The values of 0.5 MTF for AcrySof, UltraChoice, ThinOptX, and Acri. Smart IOLs were, respectively, 2.647 cycles per degree (cpd) +/- 0.833 (SD), 2.601 +/- 0.986 cpd, and 3.453 +/- 0.778 cpd. The mean 0.1 MTF values for the same IOLs were 8.720 +/- 3.074 cpd, 8.814 +/- 4.380 cpd, and 11.418 +/- 2.574 cpd, respectively. Statistical analysis did not show significant differences in 0.5 MTF and 0.1 MTF between the conventional IOL and MICS IOLs.

CONCLUSIONS

Microincision cataract surgery IOLs showed excellent MTF performance when implanted after cataract surgery, equal to that of conventional IOLs. An in vivo MTF study may be an excellent option to evaluate IOL performance in the eye.

摘要

目的

评估植入传统人工晶状体（IOL）以及专为微切口白内障手术（MICS）设计的两种IOL的眼睛的调制传递函数（MTF）。

设置

西班牙阿利坎特市阿利坎特眼科研究所研发与创新部。

方法

这项前瞻性非随机连续系列研究纳入了30只植入以下IOL之一的眼睛：传统丙烯酸可折叠IOL（爱尔康实验室的AcrySof MA60BM）或UltraChoice 1.0 ThinOptX（ThinOptX公司）或Acri. Smart 48S（Acri.Tech）MICS IOL。植入后3个月，使用光学质量分析系统（OQAS）针对5mm瞳孔计算MICS后的0.5 MTF和0.1 MTF。采用曼-惠特尼U检验对差异进行统计学分析。

结果

AcrySof、UltraChoice、ThinOptX和Acri. Smart IOL的0.5 MTF值分别为2.647每度周数（cpd）±0.833（标准差）、2.601±0.986 cpd和3.453±0.778 cpd。相同IOL的平均0.1 MTF值分别为8.720±3.074 cpd、8.814±4.380 cpd和11.418±2.574 cpd。统计学分析未显示传统IOL与MICS IOL在0.5 MTF和0.1 MTF方面存在显著差异。

结论

微切口白内障手术IOL在白内障手术后植入时显示出优异的MTF性能，与传统IOL相当。体内MTF研究可能是评估IOL在眼中性能的极佳选择。
