Retrospective Comparison Of New Edof Iol With Monofocal Iol For Both Ucdv, Ucnv And Patient Satisfaction

To demontrate comparative clinical outcomes of distance and near uncorrected visual acuity and patient satisfaction with an Extended Depth of Focus acrylic IOL and a monofocal acyrlic IOL following cataract surgery in patients with low astigmatism. 

Private practice and Ambulatory Surgical Center, Western New York, USA

28 patients were implanted with the extended depth of focus RayOne EMV (Rayner) IOL and 28 patients were implanted with the monofocal PreVue (Bausch + Lomb) IOL. All patients were calculated for a plano to -0.25 spherical target and had less than or equal to one diopter of preoperative astigmatism on both refraction and pre-operative placido topography. Inclusion criteria include patients with visually significant cataracts over the age of 45 with no history of ocular comorbidities,  active inflammation, or amblyopia. Refractions, distance, and near measurements at 4-to-6- week postop surgery. Subjective patient satisfaction questionnaires were filled out at 4 to 6 weeks postop appointments. 

98% of patients with the EMV achieved monocular UDVA of 20/40 or better and 100% had 20/40 or better binocular UDVA. UNVA in EMV cohort showed 83% of patients with 20/40 (J3) or better monocularly and 93% of patients achieved 20/30 (J2) binocular UNVA. PreVue, 90% of patients achieved monocular UDVA of 20/40 or better and 96% had 20/40 or better binocular UDVA. UNVA in the PreVue cohort showed 53% or patients with 20/40 (J3) or better monocularly and 64% of patients achieved 20/30 (J2) or better binocular UNVA. For Subjective patient satisfaction with ability to perform intermediate (18 to 20 inches) or near (10-12 inches) tasks uncorrected, EMV had an 80% satisfaction compared to 50% in PreVue.

This study suggests that the RayOne EMV provides greater depth of focus and higher patient satisfaction at intermediate and near ranges with no increase in dysphotopic side effects or loss of distance visual acuity compared to the standard PreVue monofocal IOL.
