Abstract Details

Purpose:

To determine the efficacy of Artisan toric iris-fixated lens implantation to correct high ametropia and astigmatism in keratoconus

Setting:

International Eye Center , Gaza ,Palestine

Methods:

Artisan toric lens implantation was performed in 20 eyes of 13 patients who were contact lens intolerant or were unable to wear glasses because of anisometropia, high astigmatism. Manifest refraction, uncorrected and spectacle-corrected visual acuity were performed before surgery and 1 week, 1 month and 12 months after surgery . Efficacy, percent reduction of refractive astigmatism, astigmatism correction index were determined..

Results:

The mean +/- standard deviation of the preoperative refractive cylinder was -4.06+/-2.36 diopters (D; range, -4.0 to -10.0 D), which was reduced to -1.5. Spherical equivalent was reduced from -4.24+/-4.37D before surgery to -0.75 at the final follow-up. The uncorrected and best-corrected visual acuities were >/=20/40 in 42% and 100% of eyes, respectively. There was no loss of best-corrected visual acuity and a gain of at least 2 lines in 50% of eyes.

Conclusions:

Artisan toric lens was effective for reduction of refractive astigmatism and ametropia . A longer follow-up and a larger number of patients are needed to assess the safety and the effect of the lens.
