Abstract

PURPOSE

The purpose of this study is to compare the contrast sensitivity function (CSF) between eyes of age-matched individuals with aspheric intraocular lens (IOL) and emmetropia.

METHODS

A prospective hospital-based case-control study in South India was conducted to study the CSF in the eyes of patients between the ages of 50-60 years. The CSF was compared between those with emmetropia and those implanted with an indigenous aspheric IOL. Twenty-five consecutive patients were recruited in both groups. The independent sample -test was used for analysis.

RESULTS

The mean age was 53.08 ± 1.96 years and 57.68 ± 2.85 years in normal emmetropes and emmetropic pseudophakic with aspheric IOL, respectively. The mean CSF showed a statistically significant difference ( < 0.000) between the normal emmetropic eyes and pseudophakic eyes with the values being 1.91 and 1.572, respectively.

CONCLUSION

The CSF was significantly better in the eyes of age-matched normal emmetropes when compared to those with an aspheric IOL implanted.

摘要

目的

本研究旨在比较年龄匹配的非球面人工晶状体（IOL）眼与正视眼之间的对比敏感度函数（CSF）。

方法

在印度南部进行了一项基于医院的前瞻性病例对照研究，以研究50至60岁患者眼中的CSF。比较了正视眼患者与植入国产非球面IOL患者的CSF。两组均连续招募了25名患者。采用独立样本t检验进行分析。

结果

正常正视眼和植入非球面IOL的正视人工晶状体眼的平均年龄分别为53.08±1.96岁和57.68±2.85岁。正常正视眼和人工晶状体眼的平均CSF显示出统计学上的显著差异（P<0.000），分别为1.91和1.572。

结论

与植入非球面IOL的患者相比，年龄匹配的正常正视眼患者的CSF明显更好。
