U Vision Group · Research

Evidence we generate, not just follow.

Research isn’t a side pursuit at U Vision Group — it’s how every recommendation gets made. Our surgeons and clinicians have authored more than 300 peer-reviewed publications, including Canada’s largest published series in refractive laser-assisted cataract surgery. That body of work, much of it our own, is what stands behind the care each patient receives.

Landmark Study

Canada’s largest published ReLACS series.

When U Vision Group surgeons asked whether refractive laser-assisted cataract surgery truly outperforms conventional manual surgery, they answered it the only credible way — at scale, with their own outcomes.

The result, published in the American Journal of Ophthalmology, compared efficacy and safety across 3,144 eyes — one of the largest such series in the world, and the foundation of how we counsel cataract patients today.

Research Areas

Where our questions come from.

Our research follows our patients. Each focus area below reflects a clinical problem our specialists meet in practice — and a body of published work built to answer it.

01

Cataract & ReLACS Outcomes

Efficacy, safety, astigmatic outcomes and lens-formula accuracy across thousands of laser-assisted and manual cataract procedures.

02

Retinal Disease & Surgery

Macular hole and detachment surgery, intravitreal injection safety, biosimilar therapies, and high-resolution retinal imaging.

03

Glaucoma

Micropulse laser therapy, minimally invasive glaucoma surgery, and population-level prevalence research across Canada.

04

AI in Eye Care

Artificial-intelligence interpretation of clinical images and AI-supported post-operative monitoring — published in JAMA Ophthalmology and beyond.

05

Cornea & Anterior Segment

Surgically induced astigmatism, corneal incision morphology, and anterior-segment outcomes after refractive surgery.

06

Access & Health Systems

Barriers to eye care for newcomers and rural patients, and the economics of community-based surgical delivery.

Selected Publications

A representative sample.

A selection from more than 300 peer-reviewed papers authored by U Vision Group specialists, spanning our core subspecialties. Each links to its PubMed record.

Trials & Training

Research that renews itself.

Active clinical research

Our specialists lead and participate in clinical trials and prospective studies across cataract, retina and glaucoma — including AI-supported post-operative monitoring and new intraocular lens and pharmacologic therapies. Findings feed directly back into the recommendations our patients receive.

Teaching the next generation

U Vision Group surgeons hold academic appointments and train residents and fellows through their university and hospital affiliations. Many of our publications are co-authored with the trainees we mentor — a measure of a research culture that doesn’t just generate evidence, but passes on the discipline of generating it.

Academic & Hospital Affiliations

Credibility, institutional and earned.

Our surgeons and clinicians hold teaching and staff appointments across leading Ontario academic and hospital institutions.

The evidence is ours. So is the responsibility to use it well.

Every patient who enters the U Vision Group network benefits from care grounded in our own outcomes — and a clear next step within the network, always.
