Visual and patient reported outcomes provided by a refractive multifocal intraocular lens based on continuous...

Area of Science:

• Ophthalmology
• Optometry
• Biomedical Engineering

Background:

• Presbyopia correction is a significant challenge in refractive surgery.
• Multifocal intraocular lenses (IOLs) aim to restore both distance and near vision.
• Assessing visual quality and patient satisfaction is crucial for IOL outcomes.

Purpose of the Study:

• To evaluate the visual quality and performance of the Precizon Presbyopic multifocal intraocular lens (IOL).
• To analyze patient-reported outcomes regarding visual disturbances after bilateral IOL implantation.

Main Methods:

• Prospective multicenter study involving 56 patients (mean age 65.0 ± 8.7 years).
• Bilateral implantation of the Precizon Presbyopic multifocal IOL.
• Assessment included a quality of vision questionnaire, eye examination, visual and refractive measurements, defocus curve, and contrast sensitivity at 6 months post-implantation.

Main Results:

• Absence of severe glare and haloes reported by all patients.
• Non-symptomatic glare, haloes, and starbursts reported by 75%, 68%, and 55% of subjects, respectively.
• Excellent uncorrected distance visual acuity (0.00 ± 0.09 logMAR) and near visual acuity (0.20 ± 0.13 logMAR) at 6 months.

Conclusions:

• The Precizon Presbyopic NVA IOL demonstrates a suitable quality of vision.
• It induces a low rate of photic phenomena, such as glare and haloes.
• The IOL provides excellent visual performance, meeting the visual demands of most patients.
