Abstract

OBJECTIVE

To compare visual outcomes after cataract surgery using three intraocular lenses (IOL) of different prices but similar properties.

METHODS

A comparative study with retrospective data of patients operated for phacoemulsification with monofocal IOL implants was carried out at Al-Ibrahim Eye Hospital (AIEH) from April 2021 to Feb 2022. Patients with diabetes, any preoperative ocular morbidity and unclear diagnosis were excluded from the study. Pre and post-operative best corrected visual acuity (BCVA) on 1 day, 7 day and 4-6 weeks were analyzed. IOLs were categorized on the basis of price into economical, standard and premium lenses. To minimize surgical bias, data was further stratified on the basis of surgical expertise.

RESULTS

Data of 3237 patients was analyzed. Economical lens (A) was implanted in 2647, standard (B) in 254 and premium (C) in 336 patients. On average BCVA (6/6 to 6/12) was achieved in 88.2% of patients. No significant difference was found at third follow up among BCVA of three IOls operated by senior surgeon, χ = 3.216, p = 0.20, with median (IQR) is 0.2(0.2) logMAR for Group-A, 0.1(0.2) logMAR for Group-B and 0.2(0.1) logMAR for Group-C. When results of the rest of the surgeons was considered, significant difference was found among BCVA at 3 follow-up, χ = 6.661, p = 0.036, with median (IQR) is 0.3(0.2) logMAR for Group-A, 0.2(0.1) logMAR for Group-B and 0.2(0.3) logMAR for Group-C.

CONCLUSION

When surgical factors mainly, surgeon bias is removed, all three types of monofocal IOL had similar visual outcomes.

摘要

目的

比较使用三种价格不同但特性相似的人工晶状体（IOL）进行白内障手术后的视觉效果。

方法

于2021年4月至2022年2月在易卜拉欣眼科医院（AIEH）开展一项对接受单焦点IOL植入的白内障超声乳化手术患者的回顾性数据进行的比较研究。患有糖尿病、任何术前眼部疾病及诊断不明确的患者被排除在研究之外。分析术后1天、7天和4 - 6周的术前及术后最佳矫正视力（BCVA）。IOL根据价格分为经济型、标准型和高端型镜片。为尽量减少手术偏差，数据进一步根据手术专业水平进行分层。

结果

分析了3237例患者的数据。2647例患者植入了经济型镜片（A），254例植入了标准型（B），336例植入了高端型（C）。平均88.2%的患者实现了BCVA（6/6至6/12）。在资深外科医生操作的三种IOL的BCVA中，第三次随访时未发现显著差异，χ = 3.216，p = 0.20，A组的中位数（IQR）为0.2(0.2) logMAR，B组为0.1(0.2) logMAR，C组为0.2(0.1) logMAR。当考虑其他外科医生的结果时，在三次随访的BCVA之间发现了显著差异，χ = 6.661，p = 0.036，A组的中位数（IQR）为0.3(0.2) logMAR，B组为0.2(0.1) logMAR，C组为0.2(0.3) logMAR。
