Q: What exactly is astigmatism?
A: Usually it is related to the shape factor of the front surface of the eye called the cornea. Instead of being shaped spherically like a ball bearing or a marble, it is shaped like a football, being more curved in one direction than the other. This brings light to focus at more than 1 point. The root word stigma means point and the prefix A means without a point focus in the eye.
Q: What are cataracts and how can they be treated?
A: Cataracts are a clouding of the lens inside the eye. They are common with age, certain medications and medical conditions. Patients usually feel like they are looking through a dirty window, cannot see colors the way they used to or have increased difficulty with glare. Currently, the treatment is surgery to remove the cloudy lens. Stay tuned for medical advances in cataract treatment in the future!
Q: I was just diagnosed with diabetes in August. I had glasses before and I try and use them now, but they don't help me see any better. What should I do?
A: Diabetes can have many effects on the eyes, including changes in vision. Because you are diabetic you are now covered under OHIP for an eye exam once per year with a Doctor of Optometry. These yearly exams are very important when you are diabetic as your Doctor of Optometry will ensure your prescription is stable as well as monitor the health of your eyes for any changes related to your diabetes. We watch for bleeding at the back of the eye, as well as other ocular diseases such as glaucoma. Please call our office to book your eye exam as soon as possible.
