A conventional multifocal IOL and an add-on multifocal IOL yielded similar visual outcomes and safety profiles, according to a study.

The prospective, randomized study included 29 eyes of 19 patients implanted simultaneously with a monofocal IOL in the capsular bag and an additional multifocal IOL in the sulcus (group A). Twenty-five eyes of 15 patients were implanted with a single posterior chamber multifocal IOL in the capsular bag (group B).

Visual acuity, contrast sensitivity and defocus curve were evaluated at 1 year postoperatively. Patients who received the same IOL in both eyes completed a questionnaire designed to gauge satisfaction.

Study results showed logMAR uncorrected distance visual acuity was 0.1 or better and uncorrected intermediate and near visual acuity were 0.3 or better in all patients.

Monocular uncorrected intermediate visual acuity and distance corrected intermediate visual acuity were significantly better in group A, according to the researchers. Binocular distance corrected near visual acuity was significantly better in group B.

Group A had slightly better contrast sensitivity at high spatial frequencies under almost all lighting conditions.

Patient satisfaction scores were higher in group B. However, fewer patients in group A reported disruptive light phenomena.

Macular edema was identified in one eye in group B.
