Presbyopia correction in astigmatic eyes using a toric trifocal intraocular lens with quadrifocal technology
Journal of Refractive Surgery Oct 14, 2020
Kohnen T, Lwowski C, Hinzelmann L, et al. - Researchers performed this prospective single-arm study to assess 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. This investigation was carried out at the Department of Ophthalmology, Goethe University, Frankfurt, Germany. Before registration, 25 patients (50 eyes) received bilateral implantation of the toric PanOptix IOL (AcrySof IQ PanOptix; Alcon Research LLC). At 3 months postoperatively, mean refractive spherical equivalent was 0.12 ± 0.380 D and mean refractive cylinder was −0.21 ± 0.237 D. The visual performance of the toric PanOptix IOL demonstrated good visual acuity at all distances; more than 90% obtained a reduction of the refractive cylinder below 0.75 D, high patient satisfaction despite some optical phenomena, and high spectacle independence 3 months after surgery.
