Abstract Details


To assess the 1-month and 12-month postoperative visual performance and subjective patient satisfaction following combined implantation of an extended depth of focus and trifocal intraocular lens (IOL).


Cathedral Eye Clinic, Belfast, Northern Ireland, UK


The refraction, uncorrected (UDVA) and corrected distance visual acuities, uncorrected intermediate (UIVA) and near (UNVA) visual acuities, distance-corrected intermediate and near visual acuities, and a quality of vision (QoV) questionnaire were evaluated 1 month and 12 months after implantation.


The study enrolled 100 eyes of 50 patients. The mean binocular UDVA was -0.07 logMAR ± 0.07 at 1 month and -0.10 ± 0.12 logMAR at 12 months (P= .061). The mean binocular UIVA was 0.16 ± 0.13 logMAR and 0.11 ± 0.11 logMAR, respectively (P = .009). The mean binocular UNVA was 0.19 ± 0.13 logMAR and 0.14 ± 0.10 logMAR, respectively (P = .003). The mean nighttime and day QoV scores were 8.04 ± 1.56 and 9.08 ± 0.94 at 1 month, and 8.19 ± 1.35 and 9.31 ± 0.66 for night and day at 1 year.


This combination of IOL implantation provided excellent unaided vision in near, intermediate, and distance vision 1 month and 12 months postoperatively. However, near and intermediate vision significantly improved at 1 year. There was a high overall subjective night and day QoV score which improved at the second assessment.
