AcrySof toric IOL offers spectacle independence

September 11, 2007

The AcrySof toric intraocular lens (IOL) (Alcon) offers greater spectacle independence than the monofocal AcrySof SA60AT single-piece IOL (Alcon).

The AcrySof toric intraocular lens (IOL) (Alcon) offers greater spectacle independence than the monofocal AcrySof SA60AT single-piece IOL (Alcon), according to Paul Ernest from Jackson, USA.

Dr Ernest enrolled 480 patients and randomized them to receive either the control lens, AcrySof SA60AT single piece IOL (n=237), or the AcrySof toric IOL (n=243). Each patient had at least 0.75 D of regular astigmatism and age-related cataracts in one or both eyes.

The toric IOL patients reported a significantly greater rate of spectacle independence than controls (p<0.0001). Compared with controls, the percentage of toric patients achieving an uncorrected distance visual acuity (UDCVA) of 20/20 or better (19.4% versus 40.7%, respectively) or 20/25 or better (41.4% versus 63.7%, respectively) was significant (p<0.0001).

The comparison of the lenses demonstrates that the AcrySof toric IOL offers a much greater level of spectacle independence than its monofocal counterpart.
