Message from the Chair

February 2021


The majority of us were taken aback by the Ford government’s announcement of the plan to fund for-profit cataract surgery centers across Ontario. This was a hastily conceived initiative that is being implemented quickly without any consultation of ophthalmology leadership across the province. Many hospitals across the province are not at capacity with their cataract surgery volumes; in fact, they have been asking for more cases year in and year out.  Why is the government abandoning these centers in favour of for-profit centers.  Most of us are very familiar with the private centers in the GTA.  Many of the owners are good ophthalmologists, some of whom are on our faculty and there are some of us who hold clinics and operate there.  There are those that are saying “what’s the fuss? The standards are upheld at these centers”.  The big concern is that with privatization of our health care and a move of surgery into these private centers, they will be perceived as lucrative investments.  The ophthalmologist-owner may quickly sell to private investors and walk away with their nest egg.  The private investors will then manage the hiring and firing of surgeons and be responsible for quality, safety, education and patient care.  They will oversee the tests ordered by each surgeon, the number of specialty lenses (I dislike the term “premium lenses” and I think we shouldn’t use it with patients, preferring “specialty lenses” instead) inserted by each surgeon and the number of cases each completes daily.  Remember, their responsibility is to the shareholders and their bottom line is to maximize return to investors and owners.  This will impact ophthalmology in many ways and raises important questions:
  1. Privatization jeopardizes education and residency training.  Teaching our young surgeons takes time and effort and the return on investment will be seen as poor by investors.  A private center in Kingston is asking for 2/3 of the volume performed at the Kingston Hospitals.  If they receive this volume, the Chair of the program says that will leave very few teaching cataracts at the hospital and will ultimately lead to closing of the Queen’s Ophthalmology Residency training program.  Who will teach our new generation of ophthalmologists?
  2. Private centers will credential their own surgeons and these ophthalmologists will not be required to have hospital privileges or take call.  Who will deal with complications and who will cover the emergency rooms and inpatient consults?
  3. What checks and balances will be in place to prevent inappropriate “up-charging” of patients with private fees that can increase out of pocket costs for patients who are often seniors on a fixed income?
  4. Who will do the complex and difficult cases that could slow down surgery at a private center?
  5. Will private centers allocate OR access based on surgical speed, revenue generation and the surgeon’s ability to upsell “premium” options as opposed to quality, education and patient care.
I believe that ophthalmology provides excellent service, education and research in this province.  If we were given the appropriate resources to increase our case volumes in the current setting, waitlists could be quickly reduced.  A well thought out plan can look to shift surgeries out of hospitals into non-profit-IHFs and hospital ambulatory centers in the intermediate term. This would enhance efficiency and reduce costs while being minimally disruptive.  I do hope the policy makers clearly examine the options before sending Ontario Ophthalmology on a path towards privatization.

Report on EDI

by: Dr. Nupura Bakshi, Director of EDI
After a year like no other, a year that that highlighted striking inequities in society, culture, and medicine – this new year is an apt time for reflection and making an active commitment to fostering an environment of inclusion and practicing allyship in. The EDI Committee has been hard at work behind the scenes on initiatives to enhance and uplift a culture of equity, diversity, and inclusion in the DOVS.
DOVS Code of Conduct
In April 2020, the Faculty of Medicine (FOM) revised and approved new Standards of Professional Behaviour for Clinical (MD) Faculty. In alignment with this policy, as well as other existing U of T and CPSO policies, the EDI Committee is in the process of drafting a DOVS Code of Conduct. This policy document will serve to highlight the expectations regarding professional behaviour for faculty and learners, as well as formalize a commitment to creating a learning and work environment of inclusion and equity. Once finalized and approved, this Code of Conduct will become part of appointment and reappointment processes.
DOVS EDI Interdisciplinary Grand Rounds
The EDI Committee is pleased to announce two EDI Grand Rounds scheduled for this year. These sessions will be held jointly with the Department of Anaesthesia and Pain Medicine, and the Department of Obstetrics and Gynecology. The speakers are highly sought-after leaders in their fields, and are known for their engaging and thought-provoking sessions. Please bookmark these dates and join for a stimulating discussion!

Update on FOM Learner Experience & Learner Mistreatment Disclosure Tool
In 2020, the FOM created an Office of Learner Experience, directed by Dr. Reena Pattani from the Department of Medicine. With a goal of addressing barriers to reporting learner mistreatment, guidelines for managing disclosures of learner mistreatment are currently being finalized.  Residents, fellows, and elective PGME trainees will have access to an anonymous online disclosure tool via the Office of Learner Experience.  While this disclosure tool is already available for medical students, the anticipated rollout for PGME learners is spring/summer 2021, once broad consultation has been completed by the FOM regarding the investigation, resolution, and appeals processes.

Dr. Harold Stein

It is with great sorrow that we inform you of the sudden passing of Dr. Harold Stein on January 31st, 2021. Dr. Stein will always be remembered as a wonderful person and a great ophthalmologist.  He will be missed by his colleagues and patients.

On behalf of the Department of Ophthalmology & Vision Sciences, our sincere condolences to the entire Stein family at this time.
It is with great sadness that we announce the death of Harold Aaron Stein on January 31, 2021, beloved husband of Anne Stein. Loving father of Ray (Nancy), Laurie (Bob), and Gary (Debra). Treasured grandfather of Rebecca (Michael), Emma (Jake), Maxwell, Teddy, Kelsey, Elliott, Alexa, Casey and Olivia. Dear brother and brother-in-law of Richard and Pam Stein. Dr. Harold Stein was a brilliant, kind, warm, and generous man with a great sense of humor. He was larger than life, a talented ophthalmic surgeon, an innovative and creative thinker, a renaissance man with a wide range of interests, and a storyteller with a twinkle in his eye. He loved to recount his adventures of working in developing countries, discovering new surgical techniques and to share his many ideas for academic studies. Harold practiced ophthalmology for over fifty years and was well known to doctors around the globe for his academic achievements and for pioneering the profession of Ophthalmic Assistants. During his career, he received many distinguished awards including the Lifetime Achievement Award from The Canadian Society of Ophthalmology. He enjoyed teaching residents and authored over thirty-five textbooks. He was very proud to co-found The Bochner Eye Institute named for his former partner and father-in-law, Dr. Maxwell Bochner. Harold's most constant companion was his loving wife, Anne, and their bond was exceptionally strong. She supported him in every adventure, accomplishment and challenge that came along. He was an adoring father to his three children and a treasured grandfather of nine. Harold left his mark on his family, his patients, and on the ophthalmic community worldwide. He will be deeply missed by all who knew him. A family graveside service was held on Tuesday, February 2, 2021. Memorial donations may be made to The Dr. Harold Stein Memorial Fund, c/o Benjamin Foundation,, 416-780-0324.
