Abstract

Purpose: The purpose of this study was to investigate the visual results and patient satisfaction after implantation of an extended depth-of-focus (EDOF) intraocular lens (IOL) in the second eye of patients implanted previously with a monofocal IOL in the first eye. Methods: The medical records and self-reported questionnaires from patients who were implanted with monofocal IOLs in the first eye and EDOF IOLs in the second eye (group A) and from patients implanted bilaterally with EDOF IOLs (group B) were compared for visual acuity (VA), spectacle independence, patient satisfaction, and photic phenomena. Results: Group A (23 eyes of 23 patients) had similar distance uncorrected VA and intermediate uncorrected VA compared with group B (72 eyes of 36 patients) (0.03±0.05 vs. 0.04±0.16; P=0.136 and 0.660, respectively). There was a tendency toward a better near uncorrected VA in group A compared with group B (0.15±0.14 vs. 0.23±0.17; P=0.074). Patients' perception of their VA was similar between groups. Spectacle independence for distance vision was reported by 16/17 (94.1%) and 35/36 (97.2%) patients (P=0.543), 13/17 (76.5%) and 32/36 (88.9%) patients (P=0.252) for intermediate vision, and 4/17 (23.6%) and 22/36 (61.1%) patients for near vision (P=0.011), in groups A and B, respectively. There was no difference in complaints of photic phenomena between groups. Conclusions: Patients previously implanted with a monofocal IOL in 1 eye who are interested in improving their spectacle independence can be considered for an EDOF IOL implantation in the second eye and may have similar results to those implanted bilaterally with EDOF IOLs.
