Interim Analysis Of Functional Outcomes After Implantation Of Monofocal+ Intraocular Lenses Inducing Positive Spherical Aberration Without Monovision

To evaluate the functional outcomes including visual performance and patient reported outcomes after implantation of the enhanced monofocal lenses RayOne EMV and RayOne EMV toric RAO210T (Rayner, UK).

International Vision Correction Research Centre (IVCRC), Department of Ophthalmology, University Hospital Heidelberg, Germany.  

This ongoing prospective study examines the visual outcomes of phacoemulsification combined with RayOne EMV and RayOne EMV toric RAO210T intraocular lens (IOL) implantation in 9 patients (13 eyes) and 8 patients (16 eyes) respectively, with an average age of 72 ± 9 years. Postoperative assessments at 1, 3, 6, and 12 months include uncorrected and corrected distance visual acuity (UDVA, CDVA), uncorrected and distance corrected intermediate visual acuity (UIVA, DCIVA) at 66 cm, and uncorrected and distance corrected near visual acuity (UNVA, DCNVA) at 40 cm. Binocular best-corrected defocus curve analysis ranging from +2 to -4 diopters was performed at 3 and 6 months post-surgery.

At 1 month postoperative, mean monocular visual acuity in logMAR was UDVA/CDVA (0.07/-0.01), UIVA/CIVA (0.19/0.20), and UNVA/CNVA (0.41/0.44). At 3 months follow-up, mean monocular visual acuity in logMAR was UDVA/CDVA (0.02/-0.05), UIVA/CIVA (0.23/0.22), and UNVA/CNVA (0.48/0.46). At 6 months, mean monocular visual acuity in logMAR was UDVA/CDVA (0.03/-0.04), UIVA/CIVA (0.19/0.21), and UNVA/CNVA (0.44/0.45). By 12 months, mean monocular visual acuity in logMAR was UDVA/CDVA (0.00/-0.10), UIVA/CIVA (0.27/0.29), and UNVA/CNVA (0.30/0.31).

Preliminary findings suggest satisfactory visual acuity outcomes and reduced photopic phenomena. IOL power calculation and implantation procedures for RayOne EMV and RayOne EMV toric lenses appear straightforward. Ongoing evaluation will further elucidate visual outcomes at 6 and 12 months postoperatively.
