The overall satisfaction with visual performance was high among patients who underwent refractive lens exchange and implantation with a diffractive multifocal IOL despite significant reported glare, halo and starburst issues, according to a study.
“Despite a high percentage of patients experiencing moderate to severe halo and some loss of vision, the overall satisfaction with visual performance was high. This outcome suggests that many patients are willing to sacrifice some of their existing ‘normal distance vision’ for potential spectacle independence,” the study authors said.
The nonrandomized, unmasked, retrospective chart review included 45 eyes of 29 patients who were implanted with a Tecnis multifocal IOL (ZMA00, Abbott Medical Optics) in one or both eyes. All patients had presbyopia of at least 1.5 D and preoperative uncorrected or corrected distance visual acuity of at least 20/20. All procedures were performed by a single surgeon.
Postop follow-up was conducted at 1 day, 1 week, 1 month, 3 months and 6 months. A subjective questionnaire assessing satisfaction and visual symptoms was completed by 27 patients.
Twenty-five patients (89%) reported overall satisfaction with the surgery. All patients who underwent bilateral surgery were spectacle-free at all distances postoperatively, compared to 50% of patients who underwent unilateral surgery. The highest satisfaction was reported among those with habitual preop spectacle use who underwent bilateral surgery.
Postoperative halos were reported by 78% of patients, starbursts by 48%, and night glare by 26%.
Among 13 patients who underwent unilateral surgery, mean uncorrected distance visual acuity was significantly worse in operated eyes than fellow eyes (P = .012), as was mean corrected distance visual acuity (P = .029), assuming that visual acuity in fellow eyes did not change over the course of the study.
