Lens Implants Can Permanently Restore Your Vision

Dr. Cavanaugh is one of the area’s leading refractive surgeons specializing in a variety of implant types, including Refractive Lens Exchange (RLE), to eliminate glasses or contacts

Similar to LASIK, Refractive Lens Exchange (RLE) and Implantable Contact Lens (ICL) surgeries are elective procedures designed to reduce or eliminate dependency on glasses or contact lenses. These procedures treat your nearsightedness, farsightedness, or presbyopia (near vision difficulty). Depending on the treatment, your natural human lens may be removed and replaced with an artificial lens implant or a supplemental lens implant may be used to optimize your vision. This is similar to what occurs during cataract surgery, when the cloudy human lens is replaced with an artificial lens re-establishing the clear focusing power of the eye.

Refractive Lens Exchange and Other Lens Implants

The lens of the eye is located behind the pupil. Its function is to focus light through the pupil and back to the retina so that we can see. The inherent power of the human lens largely determines the prescription of one’s eye and is partially responsible for making a patient myopic (nearsighted) or hyperopic (farsighted). In addition, the human lens can accommodate or flex to change its shape in order to focus at near and distant objects. Presbyopia describes the condition in which the human lens stiffens over time and causes difficulty reading for patients over 40 years old. Refractive lens Exchange (RLE) replaces the aging lens with a bio-compatible collamer lens, restoring your vision and eliminating the future possibility of cataract development.

Multi-Focus lens implants are the implants of choice for patients with presbyopia wanting the greatest freedom from glasses for a full range of vision — so they can see distance and near objects simultaneously quite well in both eyes without glasses, in most cases.
