Abstract Details


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.


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


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.


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.


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.
