BACKGROUND: The aim of this stud was to assess clinical outcomes after implantation of a hydrophobic toric intraocular lens (IOL) in patients undergoing cataract surgery.
PATIENTS AND METHODS: 22 eyes (16 patients) with at least 0.8 diopter (D) of corneal astigmatism having routine cataract surgery were included. After marking the final axis of the IOL, phacoemulsification, implantation and alignment of a toric IOL was performed. Uncorrected distance visual acuity (UDVA), best corrected distance visual acuity (BDVA), manifest refraction, and keratometry were measured 5 to 19 months postoperatively. Individual patient satisfaction was also recorded. The cylinder axis of the toric IOL was determined at a slitlamp examination.
RESULTS: The mean UDVA postoperatively was 0.3 logMAR±0.23 (SD) and was 0.3 logMAR or better in 63.6% of eyes. The mean refractive cylinder decreased significantly postoperatively, ranging from -3.3±1.5 D to -1.3±0.7 D. The mean absolute IOL misalignment was 7.5 degrees (range 0 to 21°). The good UDVA resulted in high levels of patient satisfaction.
CONCLUSIONS: Implantation of a toric IOL during cataract surgery was an effective and safe method to manage corneal astigmatism in this series of patients.
