What You Need to Know: Corneal Inlays

As you age, your eyes undergo several changes that may affect your vision. One change is presbyopia, which literally means “old eyes.” This means that the eye’s clear lens, which expands and contracts as you view objects close to you and from a distance becomes increasingly harder. Without its flexibility, you strain to see items – generally text – within a few feet of your face. In the past, patients were told they just had to live with presbyopia. Today, Magruder Laser Vision has several solutions for patients who suffer from presbyopia, including one of the newest technologies, corneal inlays. Read below how we are able to transform your vision so you can focus better near and from afar.

A corneal inlay is refractive, meaning it changes the angle of light as it enters the lens. In presbyopia, the angle of light is incorrect, and the point of focus is behind the retina. The retina is where vision occurs, and when the point of focus lands beyond it, the image is blurry at best.

Nearly two billion people around the world suffer from presbyopia. Most compensate for the loss of close-vision by wearing “readers” or prescription glasses. For others, glasses or contacts to improve their vision is not the best answer. Instead, they would prefer a permanent method of vision stabilization such as a corneal inlay.

What exactly is a corneal inlay? A round, transparent microlens implanted inside the cornea in front of your lens. As light refracts through the inlay, the light bends differently and is able to focus squarely on the retina to produce sharper images.

Of the three types of corneal implants currently available, only one, KAMRA, has been approved by the Food and Drug Administration. Doc Brock and his staff have been offering KAMRA inlays to presbyopic patients since 2016. KAMRA’s technology relies on tiny apertures (holes) puncturing the center of the microlens. The apertures allow gases and nutrients to flow through to the lens. A larger central aperture measuring 1.6mm brings information close to the eye in sharper focus while maintaining binocular visual acuity for items in the distance. Using a femtosecond laser during the procedure reduces the risk of corneal nerve damage and post-operative dry eye.

In 1996, Orlando ophthalmologist, Dr. Magruder, opened his practice and introduced locals to Central Florida’s first refractive surgery center. Since then, he has continued to innovate by introducing game-changing technology and pursuing ongoing education to master the latest techniques.
