Clinical outcomes of complex and uncomplicated cataractous eyes after lens replacement with the AcrySof toric IOL.

摘要

PURPOSE: to compare outcomes for uncomplicated versus complex eyes after implantation of AcrySof toric intraocular lenses (IOLs) (Alcon Laboratories Inc) in a retrospective series of cataractous astigmatic eyes. METHODS: toric IOLs were implanted in 230 eyes of 162 adult patients. Approximately half (52%, n=120) the eyes had no complications (uncomplicated group). The other 110 (48%) eyes (complex group) had a variety of complexities, including retinal or macular problems (eg, age-related macular degeneration), angle or pressure problems (eg, glaucoma), or high astigmatism that required adjunctive limbal relaxing incisions (LRIs). Outcomes were retrospectively assessed approximately 6 weeks after surgery. RESULTS: preoperative corneal astigmatism was 1.60 +/- 1.20 diopters (D) overall (1.40 +/- 0.70 D in the uncomplicated group and 1.90 +/- 1.60 D in the complex group). Residual cylinder was 0.40 +/- 0.60 D overall (P<.01 compared to baseline) and was significantly lower (P<.01) for the uncomplicated group (0.30 +/- 0.40 D) than for the complex group (0.50 +/- 0.80 D), which contained the adjunctive LRI subgroup (residual cylinder 0.80 +/- 0.70 D). A larger percentage of uncomplicated eyes (26%) than complex eyes (16%) had at least 20/20 uncorrected distance visual acuity (UDVA) (P=.05). Excluding eyes with intentionally targeted myopic postoperative spherical equivalent, no eyes lost Snellen lines of UDVA, and the average improvement in UDVA was 0.8 +/- 0.6 logMAR. Corrected distance visual acuity of the retinal/macular subgroup was poorer than the uncomplicated group pre- and postoperatively but was significantly improved by the surgery (P<.001; average improvement approximately 3 Snellen lines). CONCLUSIONS: AcrySof toric IOLs reduced cylinder and improved UDVA in both complex and uncomplicated eyes with cataractous astigmatism.
