We specialize in diseases affecting the retina and vitreous such as macular degeneration, retinal detachments, and diabetic eye disease. Retina doctors are fully trained ophthalmologists who have chosen to do additional formal training in diseases affecting the back of the eye.
This added expertise makes retina physicians able to expertly manage many diseases behind the lens such as: an eye that has filled up with blood, a retina that has separated from the back of the eye, aging changes of the retina, many eye injuries, and some tumors affecting the eye.

Dr. Johnston received his medical degree in 1992 at the University of Toronto. He then went on to do an internship in internal medicine followed by a residency in Ophthalmology at the University of Toronto. After completing his residency, he accepted a 2-year fellowship in Diseases and Surgery of the Retina and Vitreous at the Doheny Eye Institute, University of Southern California.
The retina is a thin membrane (like wet tissue paper) that lines the back of the eye. Its purpose is to turn the light into a picture that can be sent to the brain through the optic nerve. It must be attached to the back of the eye to function properly. In front of the retina sits the vitreous humour.
The retina is a thin membrane (like wet tissue paper) that lines the back of the eye. Its purpose is to turn the light into a picture that can be sent to the brain through the optic nerve. The retina is divided into 2 parts - a central part, called the macula, and an outside or peripheral part. The central part is the most important as we look straight ahead to see most things.
You should not eat or drink anything including water, after midnight the night before surgery. If you are on heart or blood pressure medications, please take them as usual before the surgery with the tiniest sip of water possible. You will need someone to bring you home from the hospital, and you should not stay alone that night.
Gas or oil bubbles are used in retina surgery to either close holes or help keep the retina attached. The gas bubbles rises up and press against the highest position of the eye. Depending on the area of damage to the retina, your doctor may ask you to position on your left side, right side, face down, or upright, or some combination of these positions.

If you have the opportunity to go somewhere else, please do. The front desk was overtly condescending in a difficult situation. The facilities seem haphazard (eye test in one corner while another patient is getting an eye injection behind a screen literally 2 feet away). I was not really listened to ("how are you?" "not good" "great- can my assistant examine you?") and was not treated with any degree of skill when difficult news was delivered. Will not return.

My wife and I were devastated to learn that she had a recurrence of the detached retina Dr. Johnston repaired a few months ago. Both he and our regular ophthalmologist, Dr Scott Schafer, were very supportive, timely and comforting. She had cataract removal that day, followed by the retinal surgery the next. Dr. Johnston is very skilled, personable, and responsive to our questions and concerns. Fingers crossed!

I was told to expect to spend 2hrs at the clinic prior to making appt.s so I knew that going in, and on occasion I have waited more than an hour. I would wait all day if necessary. I have a hereditary condition that caused eye damage and vision loss and it was very scary for me. My regular eye specialist felt I needed greater expertise for my condition and sent me to Dr. Johnston. Because of his willingness to see me the next day and because of his surgical skill, I can now see better than I have ever seen. I am so very grateful to him for giving me new and better vision.

Dr. Johnston & the technicians are fantastic, However - the woman at the front desk was rude & snapped at me because I didn't have all of my insurance cards- I don't carry the one with the payment schedule ..I've shown exactly the same card to all of my other physicians with no problem whatsoever & they can see the payment schedule when they run the card. She's just rude. I did not have to wait too long at all. But Dr. Johnston is highly recommended & I can deal with the front desk for excellent care.
