Abstract Details

Purpose:

This study is to consider the effect of Artisan phakic intraocular lens implantation on ocular higher-order aberrations (HOAs) taking into account of incision location.

Setting:

Department of Ophthalmology, School of Medicine, Pusan National University & PNU Hospital, Pusan, South Korea.

Methods:

Thirty-eight eyes of 38 patients who had undergone Artisan PIOL implantation and followed up for at least 6 months were included. Artisan PIOL implantation was performed through a scleral tunnel (sclera group) or a clear corneal (cornea group) incision. Visual acuity, special equivalents, astigmatism, HOAs, predictability, and corneal endothelial counts were analyzed between preoperative and postoperative 6 month.

Results:

All patients from both groups achieved uncorrected visual acuity of 16/20 or better. Predictability at 6 months was 96% in the sclera group, and in the cornea group it was 94%. Spherical equivalents improved significantly in both groups. Preoperative astigmatism decreased significantly in cornea group at postoperative 6 month. The HOAs increased significantly at postoperative 6 months compared to the preoperative values in both groups. The total RMS and trefoil wavefront aberration at postoperative 6 months of cornea group was significantly higher that of sclera group. Corneal endothelial cell count remained unchanged in both groups.

Conclusions:

Although corneal incision significantly reduces preexisting astigmatism, the total RMS and trefoil aberration of postoperative corneal change may be deteriorated in the visual quality after Artisan PIOL implantation.
