To evaluate the visual performance after bilateral implantation of a toric diffractive aspheric multifocal intraocular lens (IOL) with a +2.17 diopters (D) (60 cm) intermediate and a +3.25 D (40 cm) addition (add) power.

The sample of twenty-five patients (50 eyes) received bilateral implantation of the toric PanOptix IOL (AcrySof IQ PanOptix; Alcon Research LLC) before enrollment. Examination included manifest refraction; monocular and binocular uncorrected distance (UDVA) and distance-corrected (DCVA) visual acuity at 4 m and 80, 60, and 40 cm; and slit-lamp examination. At 3 months all factors were evaluated.

Mean refractive spherical equivalent was 0.12 ± 0.380 D and mean refractive cylinder was −0.21 ± 0.237 D at 3 months postoperatively. A significant decrease in refractive cylinder was observed postoperatively (P < .05), with 98% showing a postoperative astigmatism below 0.75 D. Monocular UDVA was better than 0.14 logMAR in all distances. Binocular defocus curve showed peaks at 0.00 D (−0.09 logMAR) and −1.50 and −2.00 D (−0.02 and 0.00 logMAR). The worst values between far (4 m) and near (40 cm) distance were 0.04 logMAR at −1.00 D. Despite some optical phenomena, 92% of patients would choose the same IOL again and recommend it to others.

The study concluded that the visual performance of the toric PanOptix IOL showed good visual acuity at all distances; more than 90% of the people who received the treatment achieved a decrease of refractive cylinder below 0.75 D, high patient satisfaction despite some optical phenomena, and high spectacle independence 3 months postoperatively.
