PURPOSE: To evaluate the outcomes of pseudophakic toric intraocular lens (IOL) implantation in eyes with stable keratoconus and cataract.
METHODS: Retrospective, noncomparative, case series of 12 eyes from 9 patients (mean age: 63.4±3.5 years) with stable mild to moderate keratoconus and cataract who underwent pseudophakic toric IOL implantation (AT TORBI 709M, AcriTec). Uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), manifest refraction, keratometric findings, adverse events, and postoperative complications were recorded for all eyes.
RESULTS: Mean postoperative follow-up was 9.0+8.8 months. At last postoperative follow-up, UDVA was 20/40 or better in 75% and CDVA was 20/40 or better in 83.3% of eyes. Postoperative mean refractive sphere (pre- vs postoperative: -4.80±5.60 vs 0.30±0.50 diopters [D]) and cylinder (pre- vs postoperative: 3.00+1.00 D vs 0.70+0.80 D) were significantly better (P<.01 for both). No intra- or postoperative complications occurred. No eyes had progression of keratoconus or significant IOL rotation at postoperative follow-up.
CONCLUSIONS: Pseudophakic toric IOLs are an effective option and provide good vision in eyes with stable mild to moderate keratoconus and cataract.
