Steven Dell, MD, of Dell Laser Consultants, spoke with Ophthalmology 360 at the American Society of Cataract and Refractive Surgery Annual Meeting about the first-in-human study of the OmniVu IOL.
Steven Dell, MD:
Hi, I’m Steven Dell, an ophthalmologist in Austin, Texas. The OmniVu IOL from Atia Vision is a dual-optic accommodating IOL. It features a fixed-power front optic, and then a deformable posterior fluid-filled optic that’s designed to mimic the natural accommodating function of the human lens.
Really, the best candidates for this IOL, it’s kind of hard to think of a bad candidate for this lens because it has the optical quality of a monofocal, and we want to certainly appeal to people who are seeking to avoid the absolute presbyopia of pseudophakia, but maybe want to avoid some of the dysphotopsias that might be seen with some of the multifocal or EDOF lenses. But this lens has demonstrated a very high level of near-vision performance while still maintaining superb quality distance and intermediate vision.
Today, I presented 24-month data from the first-in-human implantations of this lens, and I was really gratified to see extremely precise and accurate refractive predictability. We had very, very good uncorrected distance vision, which binocularly was 20/16, and even the intermediate vision was 20/16 binocularly with or without correction. Then at near, these patients were seeing 20/25 or J1 binocularly, either uncorrected or through the distance correction.
The level of subjective visual complaints was extremely low and comparable to any monofocal IOL, and we found that the results were sustained throughout the 24-month observation period.
We’ll continue to follow these patients. There were 19 subjects, 29 eyes in this first in human trial, and we’ll continue to follow these patients, but the next steps will involve larger and more comprehensive studies, ultimately resulting in a US FDA clinical trial.
The structure of this lens is designed to more closely mimic the natural physiological anatomy of the phakic human lens, so it occupies more volume and holds open the capsular bag in a fashion that achieves a few different things. Number 1, it allows for excellent effective lens position predictability. Number 2, it keeps the anterior capsular leaf away from the posterior capsule, which reduces the incidence of posterior capsular opacification. Number 3, it may provide a safety advantage by preventing the anterior vitreous face from migrating forward, which may provide safety from a vitreoretinal standpoint.
