Clinical Scorecard: Outcomes and Visual Performance Following the Use of Mini-Monovision Extended Depth of Focus Intraocular Lenses
At a Glance
Category
Detail
Condition
Presbyopia and cataract in elderly patients with myopia
Key Mechanisms
Extended depth-of-focus (EDOF) intraocular lenses (IOLs) using wavefront-shaping technology to elongate focal range; mini-monovision strategy inducing slight anisometropia (<1.00 D) to enhance near vision
Target Population
Adults aged ≥18 years undergoing bilateral cataract surgery with Vivity EDOF IOL implantation
Care Setting
Ophthalmology surgical and postoperative outpatient care
Key Highlights
Mini-monovision with Vivity EDOF IOL involves targeting emmetropia in dominant eye and mild myopia (0.5–1.0 D) in non-dominant eye to improve near vision.
Anisometropia less than 1.00 D can enhance near vision without significant loss of distance visual acuity or visual quality.
Monovision may reduce contrast sensitivity, stereopsis, and depth perception if anisometropia exceeds tolerance, potentially causing discomfort.
Determine ocular dominance using Mile’s test to guide mini-monovision design.
Management
Bilateral cataract phacoemulsification with implantation of Vivity EDOF IOLs.
Apply mini-monovision strategy by targeting emmetropia in dominant eye and near addition power of 0.5 to <1.0 D in non-dominant eye to enhance near vision.
Use standardized surgical technique and postoperative anti-inflammatory and anti-infective eye drops.
Monitoring & Follow-up
Postoperative follow-up at 1 day, 1 week, and 1 month to assess uncorrected distance, intermediate, and near visual acuity.
Objective visual quality measurements including modulation transfer function (MTF) and Strehl ratio (SR) at 1 month postoperatively.
Risks
Potential reduction in contrast sensitivity, stereopsis, and depth perception with monovision if anisometropia exceeds 1.00 D.
Patient discomfort such as asthenopia, dizziness, and headache related to anisometropia.
Exclude patients with concurrent ocular pathologies or history of ocular surgeries to minimize complications.
Patient & Prescribing Data
Adults undergoing bilateral cataract surgery with Vivity EDOF IOL implantation, stratified by visual preference and ocular dominance.
Mini-monovision with anisometropia between 0.5 and <1.0 D in non-dominant eye improves near vision and spectacle independence without clinically meaningful decline in distance vision or visual quality.
Clinical Best Practices
Careful patient selection excluding those with ocular comorbidities or prior ocular surgeries.
Preoperative determination of ocular dominance to guide refractive target setting.
Maintain anisometropia below 1.00 D to balance near vision improvement and minimize adverse effects on binocular vision.
Standardized surgical technique and postoperative care to optimize outcomes.
Comprehensive postoperative visual acuity and quality assessments to monitor efficacy and patient satisfaction.
