Artisan Toric Lens Implantation for Treatment of Post-Keratoplasty Astigmatism

Abstract

Abstract: : Purpose:to determine the safety and efficacy of Artisan toric lens implantation after penetrating keratoplasty to correct high ametropia and astigmatism. Methods:Eight eyes of 8 patients who were contact lens intolerant received Artisan toric lens implantation after penetrating keratoplasty. The amount of preoperative refractive astigmatism ranged from -4.0 to -13.0 D (mean -7.0 ± 2.87) and the spherical component of manifest refraction ranged from -9.0 to +7.5 D (mean 1.38 ± 5.82). Follow-up ranged from 12 to 2 months. Results:At the last follow-up refractive astigmatism was reduced to a mean of -1.97 ± 2.0 D (range 0.0 to -6.0 D). The mean percent of reduction was 75 ± 19%. The mean sphere was -0.56 ± 1.36 (range -3.0 to +1.25 D). LogMAR UCVA increased from 1.23 ± 0.46 preoperatively to 0.50 ± 0.17 postoperatively. BCVA was not reduced in any eye and increased by 2 or more lines in 6 of 8 eyes (75%). No procedure complications were noted. Conclusion:Artisan toric lens implantation after penetrating keratoplasty was effective for reduction of refractive astigmatism and increased postoperative UCVA. The procedure was safe and increased BCVA by 2 or more lines in 75% of cases.
