keratoconus-from our comments section

Keratoconus is a condition where the structure of the cornea loses its “stiffness”, and it begins to warp. This results in irregular astigmatism, which is difficult to correct with standard glasses and contact lenses. As the changes progress, the visual acuity decreases. If keratoconus develops at a young age (ie teenage years into the 20′s), the eye is more pliable, thus the changes are more dramatic. In later years, especially after 40, the structure is more rigid, so the condition is more stable. Fortunately, a new treatment called cross-linking has been developed recently that is of great benefit. Riboflavin and UV light are used to increase the links between the collagen fibers in the cornea. This reinforces the structure, and keeps it stable. So, age is a major factor as to how far the disease will progress, but technology is now allowing us to treat those that will evolve to the worse outcomes.

children’s vision

Often we are asked: “When should my child have their 1st eye exam?”. We usually like to see children at about age 3-4, just before they start school. There are times where we find blurred vision in one or both eyes, which if left untreated can cause permanent “lazy eye” (amblyopia), and learning difficulties. The earlier these problems are detected, the more effective the treatments will be. Luckily, children are covered under OHIP for yearly eye exams until they turn 20. This way, we can keep regular tabs on how things evolve as they grow, and ensure optimal vision for optimal learning.
