Purpose: To evaluate visual performance after implantation of a quadrifocal intraocular lens (IOL).

Design: Prospective, non-comparative case series

Methods: Setting: Department of Ophthalmology, Goethe University, Frankfurt, Germany.

Patient or study population: Twenty-seven patients (54 eyes) received bilateral implantation of the PanOptixIOL (AcrySof^® IQ PanOptixTM, Alcon Research, Fort Worth, TX, USA) pre-enrollment. Exclusion criteria were previous ocular surgeries, corneal astigmatism of >1.5 diopter (D), ocular pathologies or corneal abnormalities.

Intervention or observational procedure(s): Postoperative examination at 3 months included manifest refraction; uncorrected (UCVA) and distance-corrected (DCVA) visual acuity in 4 m, 80 cm, 60 cm and 40 cm slit-lamp examination; defocus testing, contrast sensitivity (CS) under photopic and mesopic conditions; and a questionnaire on subjective quality-of-vision, optical phenomena and spectacle independence were performed.

Main outcome measure(s): At 3 months postoperative UCVA and DCVA in 4 m, 80 cm, 60 cm and 40 cm (logMAR), defocus curves, CS and quality-of-vision questionnaire results.

Results: Mean spherical equivalent was -0.04 ± 0.321 D 3 months postoperatively. Binocular UCVA at distance, intermediate (80 cm, 60 cm) and near was 0.00 ± 0.094 logMAR, 0.09 ± 0.107 logMAR, 0.02 ± 0.112 logMAR, and 0.01 ± 0.087 logMAR, respectively. Binocular defocus curve showed peaks with best VA at 0.00 D (-0.07 logMAR) and -2.00 D (-0.02 logMAR).

Conclusions: Visual performance of the PanOptix IOL showed good VA at all distances; particularly good intermediate VA (logMAR>0.1) with best VA at 60 cm rather than like other trifocal IOLs at 80 cm; high patient satisfaction and spectacle independence 3 months postoperatively.
