Purpose: To report physical and psychometric outcomes in a cohort undergoing the combined implantation of a ReSTOR +2.5 and +3.0 multifocal IOL.
Setting: Private ophthalmic day surgery centre in Sydney, Australia
Methods: 56 patients underwent implantation of ReSTOR +2.5 in dominant eye and +3 IOL in non-dominant eye. †Visual acuity (VA), refraction, contrast sensitivity (CS) under photopic and mesopic conditions, and subjective quality of vision were assessed at 1, 3, 6 and 12 months.
Results: Mean pre-operative SE was 0.70 ± 2.52D. Mean post-operative SE was 0.00 ± 0.3D at 1 year. 88.9%, 63% and 100% of patients achieved bilateral uncorrected visual acuity of 6/6 or better at distance, intermediate and near respectively. CS was within normal age-related limits at all visits. VF-14 score was 83.49 ± 18.02 at 1 year. Glare and haloes were listed as severe in 33.3% of patients at 1 month. 65% of patients listed the phenomena having a mild to severe impact upon daily activities at 1 month. No patient described phenomena with impact greater than slight by 1 year.
Conclusion: The combination of multifocal IOL’s appears to provide an extended range of unaided VA without compromising visual quality. Most patients noted the presence of visual phenomena however this appeared to have minimal impact upon daily activities after an early adaptation period. Patient selection remains essential for optimal refractive and subjective outcomes.
