Clinical Report: Bilateral Enhanced Monofocal IOLs With Targeted Mini-Monovision

Overview

This retrospective observational study assessed bilateral RayOne EMV enhanced monofocal IOL implantation using a planned mini-monovision target: emmetropia in the dominant eye and approximately −0.50 D in the non-dominant eye. The supplied article excerpt reports that 25 consecutive patients (50 eyes) were included and that Month 6 outcome data were complete, but it does not provide the study’s outcome results.

Background

Conventional monofocal IOLs generally provide strong distance vision, while intermediate and near vision may remain limited. Diffractive multifocal and EDOF lenses can extend functional vision, but their light-splitting optics have been associated with reduced contrast sensitivity and photic phenomena such as glare and halos. Enhanced monofocal IOLs are designed to modestly extend depth of focus while retaining characteristics of conventional monofocal lenses. Mini-monovision targets emmetropia in the dominant eye and mild myopia in the fellow eye; the article identifies limited evidence for this strategy with bilateral RayOne EMV implantation.

Data Highlights

Key Findings

• The study reviewed records for 25 consecutive patients who underwent bilateral RayOne EMV implantation under a planned mini-monovision protocol.
• The intended refractive target was emmetropia in the dominant eye and approximately −0.50 D in the non-dominant eye.
• All patients met eligibility criteria; none were excluded or lost during follow-up, and Month 6 data were complete for all 25 patients.
• The article describes enhanced monofocal IOLs as non-diffractive lenses intended to modestly increase depth of focus while retaining distance visual acuity and optical quality associated with conventional monofocal lenses.
• The article states that prior evidence suggests enhanced monofocals improve intermediate acuity and, to a lesser degree, near acuity compared with conventional monofocals, without clinically significant reduction in distance acuity.
• The supplied excerpt does not report this cohort’s visual acuity, refractive, contrast-sensitivity, dysphotopsia, or patient-reported outcome results; therefore, the study’s clinical outcomes cannot be summarized from the provided material.

Clinical Implications

The study design and refractive targets may inform discussion of bilateral RayOne EMV implantation with mild mini-monovision, but the supplied excerpt does not provide outcome data to assess effectiveness or safety in this cohort. The article frames IOL selection and mini-monovision as relevant to patients’ visual priorities and spectacle-use expectations.

Conclusion

The supplied material describes a complete six-month cohort of 25 patients treated with bilateral RayOne EMV and targeted mini-monovision. Because study outcome results are absent from the excerpt, no conclusion about the cohort’s clinical or refractive results can be drawn here.
