Recruiting for a new contact lens study!

We are planning to conduct a research study within our practice to compare two different contact lenses that correct astigmatism and presbyopia (difficulties with close focusing): Biofinity Toric Multifocal and Ultra Multifocal for Astigmatism.

You may be eligible to participate in this new study.

What are we trying to learn?

We are aiming to find out which of these two lenses is easier to handle and also which one suits you the best. You will be asked to wear each lens for a 1-month period.

About the study

The study has several study visits over approximately a 3-4 month period:

  • Visit 1 – Screening visit to determine eligibility and initial lens fit – 1.5 hours
  • Visit 2 – Lens fitting, continued (for some, additional visits may be required) – 1.5 hour
  • Visit 3 – Provide lens pair #1 (may be combined with Visit 2) – 0.5 hour
  • Visit 4 – Review & optimize contact lens prescription, after 3-7 days – 0.5 hour
  • Visit 5 – End of month follow-up visit  – 1 hour
  • Visit 6 – Provide lens pair #2 (may be combined with Visit 5) – 0.5 hour
  • Visit 7 – Review & optimize contact lens prescription, after 3-7 days – 0.5 hour
  • Visit 8 – End of month follow-up visit  – 0.75 hour
  • Visit 9 – Exit study  – 0.25 hour

Total visit time commitment – estimated 7 hours

The visits will include standard clinical procedures that you might encounter when you attend a routine contact lens eye exam. There are some questionnaires to be completed between study visits, estimated maximum time commitment of 1 hour spread across the study period.


  • Age ≥42 years, needing a prescription for astigmatism (at least -0.75 cylinder) and needing additional help for close focus (at least +0.75DS).
  • Generally in good health.
  • Currently wear some type of soft contact lens, but do not habitually wear either of the study contact lenses.
  • Anticipate being able to wear the study lenses for at least 8 hours a day, 5 days a week.
  • Can be fit with the two study lens types (sphere +4 to -6, cylinder -0.75 to -1.75, ADD +0.75 to +2.50).


In appreciation of your time, you will receive at least $160 for completing all questionnaires and study visits. This may increase of you require additional lens fitting visits, prorated at $20 per hour. All study products will be provided.

If applicable, parking tokens will be provided.

World Sight Day Challenge

A child should never be limited by poor vision

we care about protecting your vision

As optometrists, we also care about people around the world who lack access to quality vision care. Because of this, Spadina Optometry is participating in the World Sight Day Challenge during October.

Now in its 14th year, the World Sight Day Challenge is the largest annual global fundraising campaign to address avoidable blindness caused by uncorrected refractive error –simply the need for an eye exam and glasses. The campaign is run by global charity, Optometry Giving Sight.

There are more than 1.2 billion people in the world who are blind or vision impaired because they do not have access to an eye exam or glasses.

Preventable blindness is a solvable problem and we are proud to help give better vision to those in need. Most people are inspired to learn that as little as $5 can help give an eye exam and a pair of glasses to someone living in an under-served community to transform their lives. Everyone can make a huge difference and we are thrilled to be contributing to Optometry Giving Sight.

On October 8, Spadina Optometry will fundraising and matching donations from our patients. We’d love our patients to get their eyes tested during the Challenge to help raise awareness and funds for this great cause. We invite you to join us in making a donation at

COVID-19 Update: Urgent Care Only

May 14, 2020

We are currently working remotely to fulfill online contact lens orders. You can contact us directly about your prescription and ordering a new supply of contact lenses. We are working to make sure our contact lens catalogue and pricing is accessible. We’re also available to help you with your prescription and finding the right option for your current needs.

Spadina Optometry is not yet open for in-person, non-urgent business. We are providing only URGENT CARE in-person at this time.

On May 14, 2020, the provincial government announced it was moving forward with Phase I of its framework to return to business, however, the directive that prevents optometrists and other health care providers from providing non-urgent (routine) care in person is still in place. Optometry offices are not yet open for in-person, non-urgent business. Optometry offices are starting to prepare for the eventual return to non-urgent care, and the College has provided optometrists with guidance to help with this transition.

College of Optometrists of Ontario

We are providing in-person urgent care. Please contact us to make arrangements for a tele-optometry consultation.

Our offices are preparing for the eventual return to non-urgent care, following the guidance provided by the College of Optometrists to help with this transition back to seeing patients.
