Three-Month Visual And Refractive Outcomes For A Novel Refractive Partial Range Of Field Extended Intraocular Lens

To outline the postoperative objective visual and refractive outcomes and subjective quality of vision following bilateral implantation of a new refractive partial range of field extended (PRoF-Ex) intraocular lens (IOL).

Cathedral Eye Clinic, Belfast, Northern Ireland, UK

The study enrolled 39 patients bilaterally implanted with the Tecnis PureSee IOL (Johnson & Johnson). The refractive aim in the first eye (dominant eye) was the first myopic target, and a micro-monovision offset up to -0.75 D for second nondominant eye. Refraction, binocular uncorrected distance (UDVA), intermediate (UIVA) and near (UNVA) visual acuities, binocular defocus curves and quality of vision questionnaires (QoV) were evaluated 3 months postoperatively. 

The mean binocular UDVA was -0.07 ± 0.07 logMAR (range, -0.20 to 0.08) 3 month postoperatively. The mean binocular UIVA was 0.07 ± 0.0 (range, 0.10 to 0.5) logMAR, and the binocular UNVA was 0.23 ± 0.10 (range, 0.10 to 0.60) logMAR. High subjective satisfaction was reported, with a day QoV score of 8.45 ± 1.02 (range, 6 to 10) and a night score of 7.86 ± 1.13 (range, 6 to 10). Minimal dysphotopsias were reported. Sixty-nine percent of patients reported complete spectacle independence.

This new refractive partial range of field extended IOL provides a satisfactory range of vision with minimal visual side effects and high patient satisfaction. The potential need for reading glasses should be outlined to the patient preoperatively. Outcomes from a longer postoperative follow-up and with greater numbers will be reported at the conference.
