Kohnen T. Optical quality and refractive outcomes after implantation of toric and non-toric version of a quadrifocal intraocular lens. Presented at: European Society of Cataract and Refractive Surgeons winter meeting; Feb. 19-21, 2021 (virtual meeting).

Kohnen reports he is a consultant to Alcon.

A prospective comparative case series of 50 patients implanted bilaterally with either the toric or non-toric version of the AcrySof IQ PanOptix aspheric quadrifocal IOL from Alcon showed comparable outcomes.

“At 3 months, uncorrected VA for distance (4 m), intermediate (80 cm and 60 cm) and near (40 cm) was equally good with both the toric and non-toric multifocal at all distances. Distance corrected VA outcomes were even better. The defocus curve showed very similar outcomes, with only a slight difference at intermediate,” Thomas Kohnen, MD, PhD, said at the virtual European Society of Cataract and Refractive Surgeons winter meeting.

Spherical equivalent was also comparable, with 78% of patients in the non-toric group and 66% of patients in the toric group within +0.25 D of intended correction. Contrast sensitivity outcomes were comparable and only slightly inferior as compared with those of the aspheric monofocal version of the same IOL.

Lens rotation at 3 months was evaluated in the toric group, in which rotational stability is a critical parameter.

“In 49 eyes, lens rotation was less than 5°. Only one eye showed a difference of 7°. No lens needed to be repositioned,” Kohnen said.

Patients were asked to answer a quality of vision questionnaire in which daily life activities were rated from 1 (good) to 6 (bad).

“With both versions of the lens, very good outcomes were reported for TV, theater, home cooking, using PCs and reading newspapers, with a grading between 1 and 2. The weaker point was night driving, which still had a grading of 3, identical with both the toric and non-toric version of the IOL,” Kohnen said.
