Initial Visual Outcomes With A Non-Diffractive, Extended Depth Of Focus Intraocular Lens (Iol) In Patients Targeted For Micro-Monovision

To assess the visual outcomes following bilateral implantation with a non-diffractive, extended depth of focus IOL. A monovision approach was taken with myopia of <-1.25D targeted in the non-dominant eye

BMI Southend Private Hospital

This is an ongoing, case series of 50 patients implanted bilaterally with this EDOF IOL. Subjects underwent routine phacoemulsification and IOL implantation by a single experienced Consultant Ophthalmic Surgeon and will attend post-operative study visits 3 to 6 months post-operatively and after 12 months. Visual outcomes including unaided and best distance corrected distance visual acuity(UDVA and BCDVA)(6m), intermediate visual acuity (UIVA and BCIVA)(70cm) and near visual acuity (UNVA and BCNVA)(40cm). Monocular and binocular defocus curves were plotted and Pelli-Robson contrast sensitivity testing was performed.

In the dominant eye, UDVA was 0.11± 0.05 LogMAR, improving to 0.00± 0.04 BCDVA. In the non-dominant eye, BCDVA was 0.05 ± 0.05 with mean spherical equivalent of -1.03± 0.59. Binocular UDVA, UIVA and UNVA were 0.09 ± 0.05, 0.16 ± 0.18, 0.32 ± 0.19 LogMAR respectively. Best corrected monocular defocus curves showed VA>0.20LogMAR from +0.50 to -0.50, however binocular uncorrected shows an extended range from +0.50 to -1.50D of defocus

Our initial results show high patient satisfaction and spectacle independence. The optical design of the lens appears to provide patient with an enhanced range of focus which is further augmented by a micro-monovision approach.
