Abstract Details

Purpose:

To compare the intraoperative aberrometry (IA) versus ASCRS online calculator for intraocular lens (IOL) power calculation, in eyes undergoing cataract surgery after prior myopic LASIK procedure.

Setting:

Department of Ophthalmology, Centro Hospitalar e Universitário de Coimbra, Portugal

Methods:

Retrospective analysis of 9 patients undergoing cataract surgery with prior myopic LASIK procedure. Patients underwent intraoperative aberrometry and ASCRS online calculator for IOL power estimation. Comparative effectiveness analysis was done to evaluate the accuracy of IOL power determination of these two methods.

Results:

In 9 eyes, the IA achieved a median absolute error of 0.38 (0.03 – 0.83) and a mean absolute error of 0.40 ± 0.28. The ASCRS online calculator showed a median absolute error of 0.36 (0 - 1.25) and a mean absolute error of 0.39 ± 0.34. The IA and ASCRS online calculator did not reveal significantly different capability to determine the estimated IOL power (p = 0.96). However the IA showed a minor range of median absolute error.

Conclusions:

The IOL power estimation in patients with prior myopic LASIK was predicted with similar accuracy using the IA or ASCRS calculator online.
