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.

A Message to Our Patients

Although the Governor has rescinded the mask mandate, we have been advised by the Texas Optometry Association that Optometrists follow Infection Control Guidance for Healthcare Professionals recommended by the Centers of Disease Control (CDC). In addition, most, but not all, of our employees are vaccinated. We are hoping to have our entire staff vaccinated by May 1st, 2021.

Until all staff members are vaccinated, the continued safety and well-being of our patients and staff is our number one focus. Masks will be required to be worn by all patients, visitors, and staff while in our practice. We will also continue to follow the CDC’s guidelines and recommendations throughout the practice.

We thank you for your understanding and helping us protect our patients, families, and staff.
