Abstract

Purpose

To report the surgical results of transscleral fixation of foldable acrylic intraocular lens with a unique haptic shape (CORNEALⓇ, ACR6D, France).

Methods

We analyzed the medical records of 18 patients (19 eyes) who had transscleral fixation of posterior chamber intraocular lens implantation from July 2004 to July 2006.

Results

According to the cause of operation, there were five eyes with complicated cataract, eight with trauma, and six with aphakia associated with a previous operation. The mean age of the patients was 55.9±21.2 years. The mean preoperative best-corrected visual acuity was 0.31±0.35, and the postoperative value was 0.63±0.29 (p<0.05). The mean preoperative spherical refractive equivalent was 6.58±5.33 diopter, and the postoperative value was -1.77±1.59 diopter. The mean refractive error was -1.13±1.57 diopter. This showed a myopic shift (p<0.05). The mean astigmatism decreased with time, and it stabilized two months after the operation. The trend was toward mild against-the-rule astigmatism. The mean follow-up duration was 11.0±7.6 months.

Conclusions

In eyes with inadequate capsular support, transscleral fixation of posterior chamber intraocular lens implantation with CORNEALⓇ lenses is a safe and effective procedure for visual correction.
