Synchrony dual-optic accommodating intraocular lens. Part 2: pilot clinical evaluation

Area of Science:

• Ophthalmology
• Biomedical Engineering
• Retinal Science

Background:

• Cataract surgery often results in a loss of natural accommodation.
• Intraocular lenses (IOLs) aim to restore visual function after cataract removal.
• Accommodating IOLs are designed to mimic the eye's natural focusing ability.

Purpose of the Study:

• To assess the clinical performance of the Synchrony dual-optic accommodating intraocular lens (IOL).
• To compare the accommodative range of the accommodating IOL with a control group.

Main Methods:

• A prospective case series with a retrospective control group was conducted.
• 21 patients received the Synchrony dual-optic accommodating IOL, compared to 10 patients with a monofocal IOL.
• Visual acuity and accommodative range via defocus curves were measured at multiple follow-up intervals.

Main Results:

• All eyes achieved a best-corrected distance visual acuity of 20/40 or better.
• Uncorrected near visual acuity was 20/40 or better in all patients.
• The accommodating IOL group showed a significantly greater mean accommodative range (3.22 D) versus the control group (1.65 D).

Conclusions:

• The Synchrony dual-optic IOL shows potential for restoring accommodative function in pseudophakic eyes.
• This accommodating IOL represents a promising option for patients seeking improved near vision after cataract surgery.
