Honoured to spend last Wednesday at the University of Ottawa to deliver Visiting Professor Grand Rounds, then resident and fellow teaching rounds.

Grand Rounds covered a wide range of topics spanning modern cataract and refractive surgery, including biometry and formulas, IOL calculations, evidence-based management of astigmatism, contemporary full-visual range IOLs, and advanced phaco techniques on a venturi platform. With ~120 slides in 50 minutes, I have zero academic chill.

In teaching rounds we reviewed IOL material science, spherical and chromatic aberration, MTF and defocus curves, challenging cases in surgical planning, as well as management of refractive surprises and adverse effects of contemporary full-visual range IOLs.

One of the highlights was spending time at the Ottawa Eye Institute with Mona Koaik, MD, and Setareh Ziai, MD, two star surgeons I’ve collaborated with at meetings in the past.

Always energizing to connect with colleagues who are passionate about pushing cataract and refractive surgery forward while investing deeply in education and mentorship. Thanks again to the entire University of Ottawa ophthalmology program for the warm welcome and hospitality.

Featured throughout this month’s Review of Ophthalmology cover story on the newest premium IOLs: TECNIS PureSee, enVista Envy, TECNIS Odyssey, Clareon PanOptix Pro, and FineVision HP, alongside my US colleagues George O. Waring IV, MD; John Hovanesian, MD; Richard Davidson, MD; Karl Stonecipher, MD; and Joseph Christenbury, MD.

In this interview, I weigh in on:

TECNIS PureSee. A purely refractive, pupil-independent EDOF that has shown no significant decrease in contrast sensitivity compared to monofocal controls in studies to date, including the recent FDA IDE. Given the uncompromised quality of vision, coupled with impressive tolerance to residual refractive error, I share excellent experience in post-refractive eyes (which we’ll present at ESCRS 2026) where exact targets are harder to hit.

enVista Envy. A continuous full-visual-range (FVR) IOL with no significant difference in bothersomeness to glare, halos, or starbursts compared to monofocal controls on a directed, validated, open-source questionnaire (QoV) in our prospective, multi-centre, Canadian clinical trial. With smoothed-edge, submicron diffractive echelettes and a distance-dominant design under mesopic conditions, the profile might appear to suggest a near vision tradeoff, but this was demonstrated not to be the case, as 84.3% of patients in the Canadian trial reported “no” or only “a little” difficulty seeing objects up close in poor or dim light.

Clareon PanOptix Pro. The most compelling data so far comes from a contralateral-eye study of 83 subjects comparing Pro to the original PanOptix. Visual acuity was non-inferior at distance, intermediate, and near, but the real differentiator was patient preference: nearly 2:1 in favour of the Pro eye, with most patients also preferring it for reduced halos and starbursts.

It’s an extraordinary moment in surgical vision correction technology. The options and side-effect profiles we have now are remarkable. My advice to colleagues: don’t be afraid to branch out beyond the platforms you’ve historically used.

Thanks to Liz Hunter and the Review of Ophthalmology team.

Spent an incredible weekend in Florida at one of my favourite annual courses: the Bausch + Lomb Surgical Mentoring Resident Program 🌴

This year we had 86 residents from across North America, a 4-hour immersive wet lab covering key anterior segment techniques, plus small-group case discussions and surgical planning.

I’m blown away. These resident physicians are working on skills I didn’t have until after graduation.

Huge thanks to Medical Affairs, the amazing faculty, and especially the residents, whose energy and skill level raise the bar every year.

With advances in technology and the skills of the surgeons of tomorrow, the future of surgical eye care is incredibly bright.

Fresh off flights from Asia, I had the opportunity to join the Johnson & Johnson Surgical Vision US National Sales Meeting in Wildhorse Pass 🌵 to discuss the future of advanced technology IOLs.

Great reconnecting with friends and industry partners, and finally meet after collaborating from a distance.

The pace of innovation is staggering.

Six perfect days in India 🇮🇳 my favourite country I’ve ever visited. Thank you AIOS for the invitation.

Incredible and busy days of lectures, instructional courses, and learning from colleagues on another continent doing unbelievable work in surgery.

I’ll always remember the warmth of the All India Ophthalmology Society, being welcomed into their professional community and rich cultural traditions, and coming away with new friendships and professional relationships.

Not pictured: me at one of the galas in full Indian National Dress.

NEW PUBLICATION - 16 March 2026

We know from the work of Julie and Steve Schallhorn that just 0.50D of residual astigmatism is visually significant and deserves attention in surgical planning. This paper demonstrates that with basic equipment already available in your office and OR, you can reliably reduce even the smallest amounts of visually-significant astigmatism with ultra-low cylinder power toric IOLs, and further supports that the rule-of-thumb that we should only treat >1.00D of pre-operative cylinder is not supported by contemporary evidence.

For surgeons: The treatable population is larger than keratometry alone suggests. Even a near-plano eye on keratometry can be predicted to benefit from a 0.90D or 1.00D toric IOL once posterior corneal astigmatism and surgically induced astigmatism are accounted for. Run contemporary toric calculators on every eye. This data supports routine toric IOL planning using only the basic equipment already in your practice. An IOLMaster 500, a placido-disk topographer, and manual marking were sufficient to achieve 0.59D of cylinder reduction in a real-world consecutive case series. No intraoperative aberrometry. No digital toric alignment. The barrier is lower than you think.

For industry partners: Regardless of which platform you support, your surgeons may be systematically underutilizing your ultra-low (

This weekend, we welcomed Julie Schallhorn, MD (UCSF) and Kamran Riaz, MD (Dean McGee Eye Institute, OKC) to Banff as guest faculty for our provincial society meeting. Two of the most influential surgeon-scientists in the world whose work continues to shape modern cataract and refractive surgery. Thank you, Julie and Kam 🙏

Full circle moment.

Featured in the alumni publication of St. Paul’s College at the University of Manitoba, where it all began in undergrad. Grateful for the friends, mentors, and opportunities that shaped the early chapters.

Fun fact: during my year as head of the Students’ Association, our team started the beer gardens that still run every fall 🍻

18 years since I last walked into the Manitoba Club, never thought I’d be invited here to discuss surgery. Thanks to Johnson & Johnson Surgical Vision for the invitation, my good friend and industry partner Sam Chang, and my colleagues in Manitoba for braving the winter storm.

2h45 minutes straight of presentations, discussion and Q&A, a career record. In spite of the song by Winnipeg’s fourth best band, I love this city.
