Comparison of clinical and patient-reported outcomes with bilateral AcrySof toric or spherical control intraocular lenses

Abstract

Purpose: To compare clinical and patient-reported outcomes with bilateral implantation of AcrySof toric or spherical control (Alcon Laboratories Inc) intraocular lenses (IOLs).

Methods: Patients with cataract and corneal astigmatism who previously received either an AcrySof toric IOL or an AcrySof spherical control IOL were offered implantation of the same IOL in the fellow eye. Six-month assessments included visual acuity, refractive cylinder, spectacle use, and patient satisfaction.

Results: The study included 62 patients (toric, n=40; control, n=22). All corneal incisions were temporal, with final mean incision sizes of 3.0 mm for the toric IOL and 3.1 mm for the spherical control IOL. A significantly greater proportion of patients with toric IOLs achieved spectacle independence for distance vision and did not require prescription glasses for near or distance vision (P=.0190). Patients with toric IOLs had significantly less residual refractive cylinder (P<.0001) and better binocular distance uncorrected visual acuity (UCVA) (P=.0014) than those with spherical control IOLs.

Conclusions: Patients with bilateral AcrySof toric IOLs achieved superior spectacle freedom, residual refractive cylinder, and distance UCVA compared to patients with bilateral spherical control IOLs.
