Abstract Details

Purpose:

To report 9 cases of visual acuity improvement after phakic anterior chamber intraocular lens (IOL) implantation in high myopic adult patients with anisometropic amblyopia.

Setting:

Department of Ophthalmology of Hospital Pedro Hispano, Matosinhos, Portugal

Methods:

Nine eyes of nine patients (8 women and 1 man) with high myopia and anisometropic amblyopia were operated with implantation of phakic anterior chamber IOL (2 Artisan and 7 Artiflex, Ophtec®, with 5 toric IOL) and followed for more than six months. Uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), manifest refraction, biomicroscopy, tonometry, central endothelial cell count (ECC) and complications were evaluated.

Results:

The mean age of patients was 34.89±6.83 years. The median follow-up time was 11 months. Preoperative mean refraction (spherical equivalent, SE) was -10.06±3.13 diopters (D), and improved to a mean of -0.32±0.31D postoperatively. Mean preoperative BCVA was 0.25±0,11 logarithm of the minimum angle of resolution (logMAR) and improved to a mean BCVA of 0,05±0,06 logMAR at last follow-up (Wilcoxon test, p=0,007). The BCVA improved 2 lines or more in all eyes. The mean endothelial cell loss was 2.02% at last follow-up. Development of cataracts, glaucoma and pupil abnormalities were not demonstrated in any case.

Conclusions:

This study indicates that anterior chamber intraocular lens implantation may be an effective surgical alternative for the correction of high myopic adult eyes with anisometropic amblyopia. However, long-term studies are necessary to assess possible complications and safety.
