Corneal Inlays and Onlays

Corneal inlays and onlays are corneal implants that are used to correct presbyopia, a common condition for individuals over age 40 in which the eyes have difficulty focusing on near objects. Presbyopia occurs as the lens of the eye begins to age and weaken, reducing the ability to focus on close objects without the assistance of reading glasses or another visual aid.

Corneal implants, such as inlays and onlays, offer a treatment solution to correct presbyopia as an alternative to using reading glasses or multifocals to obtain clear vision at a close range. Corneal inlays and onlays are like tiny contact lenses that are inserted into the cornea which reshape it to improve the refractive power and thereby improve near vision. Unlike corrective laser surgery such as PRK or LASIK the actual corneal tissue isn’t touched, but rather the shape of the cornea is changed by the transplanted lens.

Corneal inlays are placed in the stroma, the middle layer of the cornea (thus the name “in-lays”), while onlays are implanted closer to the surface of the cornea, under the epithelium, which is the thin outer layer of the cornea. The procedures for both inlays and outlays are relatively simple and quick, with minimal recovery.

Corneal Inlay and Onlay procedures are still in the early stages of development and with a number of clinical trials in progress, the technology should only improve in coming years.

To our valued Patients:

To reduce the spread of Coronavirus Covid-19, The College of Optometrists of Ontario has recommended that our office sees urgent care cases only. As a result, we are on an “On Call” status and will see urgent care patients as necessary by appointment. If you have an eye emergency and require urgent care please contact info@bayblooroptometry.com or call the office and state: what your emergency/urgent eye issue is; when the issue began; and any symptoms you are experiencing. For all other inquiries, including new contact lens orders for existing patients, messages may be left in the same manner as above, and will be responded to as soon as possible.

We will be checking voicemail and email daily.

We thank you for your understanding and continued support and wish you all the best in good health.
