In clinical trials of a 1-piece acrylic toric IOL, data provided by the FDA indicated uncorrected acuity of greater than 20/40 in 93.8% of 198 patients implanted with the IOL (all sizes combined). With the plate-haptic IOL, postoperative astigmatism was less than 0.50 D in 48% of patients and less than 1.00 D in 75%–81% of patients; results were 61.6% and 87.7%, respectively, for the 1-piece acrylic toric IOL.
For those patients with corneal astigmatism greater than that correctable by toric IOLs, surgeons may opt to simultaneously or sequentially correct residual astigmatism with incisional or laser procedures.
