Visual outcomes in patients with bilateral early to moderate primary open-angle glaucoma following wavefront-shaping partial-range of field-extend intraocular lens implantation.

BACKGROUND/AIMS: To assess binocular visual performance, visual acuity at different contrast levels and visual disturbances in patients with primary open-angle glaucoma (POAG) undergoing bilateral cataract surgery with the placement of wavefront-shaping partial-range of field-extend (PROF-Ex) intraocular lens (IOL).

DESIGN: Prospective, descriptive, single-arm study with 3 months of follow-up.

METHODS: Patients diagnosed with bilateral early-to-moderate POAG were included and underwent cataract surgery with implantation of a PROF-Ex IOL (AcrySof IQ Vivity, Alcon Healthcare) bilaterally. Postoperative outcomes were measured in binocular conditions for visual acuity (uncorrected and corrected at varying distances and contrast levels), contrast sensitivity and visual disturbances assessed through light distortion analysis in terms of the light distortion index (LDI) and best-fit circle radius.

RESULTS: 27 patients were included, with a mean age of 74.2±8.1 years. Three months after surgery, binocular corrected visual acuities at 100% contrast were -0.01±0.06, 0.11±0.08 and 0.26±0.13 LogMAR for far, intermediate and near distance vision, respectively. Those at 25% contrast were 0.57±0.11 and 0.65±0.12 LogMAR for intermediate and near distance vision, respectively. The mean binocular contrast sensitivity was 1.63±0.11, and the mean LDI was 13.28±7.06. No significant adverse events were recorded.

CONCLUSIONS: The wavefront-shaping PROF-Ex IOL technology shows positive outcomes in terms of visual acuity, contrast sensitivity and visual disturbances for patients with bilateral early-to-moderate POAG. Thus, wavefront-shaping PROF-Ex technology lenses can be a viable and effective option for patients with POAG seeking spectacle independence.
