A toric IOL used in refractive lens exchange not only addressed spherical and cylindrical refractive errors, but also delivered good visual acuity, with nearly 85% of patients having 20/25 or better uncorrected visual acuity, according to a prospective study.

The nonrandomized, observational case series examined 32 eyes of 19 consecutive patients. Study subjects had more than 1 D of pre-existing corneal astigmatism. All patients were implanted with the AcrySof toric IOL (Alcon).

After surgery, patients took a questionnaire measuring satisfaction, quality of vision and spectacle dependency.

Researchers found that at 6 months follow-up, UCVA was 20/32 or better in 100% of the eyes studied. For best corrected visual acuity, 100% of patients achieved 20/25 or better. In addition, after surgery, one eye lost one line of vision, and 16 eyes had no loss. Four eyes gained one line, and 11 eyes gained two lines or more.

The survey found good patient satisfaction, "without reporting severe visual phenomena (from none to moderate)," according to the study authors.
