Occupation: Ophthalmologist, Gimbel Eye Centre; Associate Professor, University of Calgary

In 2024, Adam Muzychuk implanted a lens that had never been used commercially anywhere in the world into the eye of a Calgary patient.

Since then, this lens — the enVista Envy intraocular lens made by Bausch + Lomb — has been used in more than 10,000 surgeries worldwide. “It’s a tremendously exciting time. It’s also a challenging time to be a surgeon in that technologies are coming out so fast,” Muzychuk says.

That’s just one of the ways that Muzychuk, an ophthalmologic surgeon at the Gimbel Eye Centre, is driving innovation in ophthalmology and making sure Calgarians have access to the latest technology.

Muzychuk was born and raised in Winnipeg. Just two weeks into medical school, he decided to make Calgary his home.

“It’s a very welcoming city,” he says. “That allows people to lay down roots and become part of the community very quickly.”

He was drawn to eye surgery because of the dramatic change it makes in patients’ lives. After opening his practice, he became interested in new technologies and machine learning — things that were beginning to transform the field — and started to participate in research.

In 2021, he led the key clinical trial of the then-unnamed enVista Envy lens, part of a new generation of lenses that correct vision at near, medium and far distances with reduced side-effects compared to previous lenses that did the same thing. This led to Health Canada’s 2024 approval of the lens.

This spring, he implanted Canada’s first TECNIS Odyssey lens, another new intraocular lens, into a Calgary patient.

Muzychuk performs more than 1,000 procedures a year, teaches in UCalgary’s ophthalmology program, and works with industry partners to launch new technologies.

He does all this while being strict about his work hours.

“I built my schedule into something that was sustainable, because it would be really hard if I was away all the time,” he says.
