Visual Outcomes and Patient Satisfaction for Trifocal, Extended Depth of Focus and Monofocal Intraocular Lenses.

Abstract

PURPOSE:

To assess visual outcomes and patient satisfaction for trifocal and extended depth of focus (EDOF) intraocular lenses (IOLs) compared to monofocal IOLs with and without monovision.

METHODS:

Consecutive patients underwent bilateral cataract extraction surgery and implantation of either monofocal IOLs, monofocal IOLs using monovision, EDOF IOLs, or trifocal IOLs. Patients with preoperative biometric data, postoperative refraction, and visual acuity who completed a questionnaire regarding satisfaction and side effects were included. Visual outcome, spectacle independence, patient satisfaction, and subjective photic phenomena were assessed.

RESULTS:

Each group comprised 50 patients (100 eyes). The mean postoperative uncorrected distance, intermediate, and near visual acuities (logMAR) were: 0.17 ± 0.14 (Snellen 20/30), not applicable, and not applicable for monofocal; 0.08 ± 0.12 (Snellen 20/24), not applicable, and 0.07 ± 0.12 (Snellen 20/23) for monovision; 0.03 ± 0.08 (Snellen 20/21), 0.08 ± 0.12 (Snellen 20/24), and 0.23 ± 0.17 (Snellen 20/34) for EDOF; 0.07 ± 0.09 (Snellen 20/23), 0.08 ± 0.11 (Snellen 20/24), and 0.02 ± 0.06 (Snellen 20/21) for trifocal. Spectacle independence was reported by 36%, 70%, 74%, and 92% of patients, respectively. Postoperative halos and/or glare were experienced by 2%, 6%, 14%, and 38%, respectively, of which 2%, 0%, 6%, and 10%, respectively, were functionally disturbing. A total of 64%, 72%, 78%, and 76%, respectively, would choose the same IOL again.

CONCLUSIONS:

Patient satisfaction rates were high in all groups. Trifocal IOLs were more effective in improving unaided whole range of vision, but were associated with a higher rate of photic phenomena. The EDOF IOL and monovision provided partial spectacle independence with less photic phenomena. [J Refract Surg. 2019;35(7):434-440.].
