Abstract

Purpose: To implant a posterior chamber intraocular lens (PC-IOL) in aphakic eyes without capsular support, transscleral suturing of the intraocular lens (IOL) is commonly performed. However, this procedure is difficult and time-consuming. An intrascleral posterior chamber IOL fixation technique has recently been developed, and the purpose of this study was to compare the outcomes after the use of these two techniques.

Methods: The medical records of 18 consecutive aphakic eyes of 16 patients (mean age; 72.0±9.2 years) who had an intrascleral PC-IOL fixation (IS-IOL group) and 15 consecutive aphakic eye of 13 patients (72.6±18.5 years) who had transscleral suturing of the PC-IOL (TS-IOL group) were retrospectively reviewed. All surgeries were performed by a single surgeon (SK). The surgical time, changes in best-corrected visual acuities (BCVAs), changes in corneal endothelial cell density, surgical-induced astigmatism, and postoperative high-order aberrations (HOAs: assessed by Topcon KR-9000PW, Topcon Corporation, Tokyo Japan) were compared for the two groups

Results: The postoperatively BCVAs improved by >0.2 logMAR units or were unchanged in all eyes in the 2 groups. Between the 2 groups there were no significant differences in the changes in the BCVAs, surgical-induced astigmatism, and different HOA values except for ocular total HOAs (0.221 μm root mean square (RMS) in IS-IOL group, 0.496 μm RMS in the TS-IOL group, P=0.031, unpaired t-test). The mean surgical time to fixate the IOL was significantly shorter in the IS-IOL group (28.3 min) than in the TS-IOL group (37.6 min, P=0.001, unpaired t-test). In the IS-IOL group, one fixated IOL dislocated 2 months after the surgery. The patients were followed for 2.8 months in the IS-IOL group and 4.5 months in the TS-IOL groups.

Conclusions: Although further investigations with larger number of patients and longer follow-up are necessary, intrascleral PC-IOL fixation may provide better PC-IOL fixation with shorter surgical time compared with transscleral suturing of a PC-IOL.
