Presbyopia Correction Treatment Options
Presbyopia is a common visual disorder that usually affects adults in their 40s and 50s. The disease gradually robs a person of their ability to focus clearly on objects nearby (without affecting their distance vision). Dr. Samer Khosrof of Leading Lasik is the ophthalmologist of choice for individuals struggling with the effects of presbyopia in Brooklyn. He offers several ways to correct presbyopia and restore sharp near vision.
What Causes Presbyopia?
The eye’s lens is responsible for refracting (or bending) light rays that enter the eye; the light is focused on the retina, which converts the light into messages that are sent to the brain to interpret. A youthful, healthy lens is soft and elastic, so it can shift easily to focus on objects that are close and distant.
With age, the lens hardens and becomes more rigid, affecting the eye’s ability to focus light on the retina. The aging process also changes the muscle fibers around the lens that help it to shift and focus on objects close by. These changes are what lead to presbyopia. Individuals with presbyopia tend to have problems with tasks like reading, sewing and sending a text message. They usually must hold reading material at an arm’s distance.
Reading glasses – The simplest way to correct presbyopia is with a pair of glasses with bifocals. Bifocal means the lens of the glasses provide focusing power at two distances (near and far). Usually the lower portion of the lens has a stronger prescription for near vision and the rest of the lens has a weaker prescription for distant vision. The prescriptions are differentiated with tiny lines.
Another type of eyeglasses that can correct presbyopia feature progressive addition lenses, which have a more gradual transition between the different prescriptions. On the other hand, some people with presbyopia opt for traditional reading glasses, which are worn only while reading or performing other tasks up close. Reading glasses can be purchased over-the-counter in a drugstore, or obtained through a prescription with Dr. Khosrof.
Contact lenses – Individuals with presbyopia may choose to wear multifocal contact lenses instead of eyeglasses. These contacts are designed to restore clear vision at multiple distances. Another way to correct presbyopia through contact lenses is to wear one lens with a prescription for distance vision and the other with a prescription for near vision; the eyes then work together for different tasks. This tactic is known as monovision.
Surgical correction – Presbyopia can also be corrected through surgery. A procedure known as conductive keratoplasty (CK) uses radio energy to improve the curvature of the cornea and improve near vision. CK is performed on only one eye and provides temporary results.
Laser vision correction with LASIK, which involves using laser energy to reshape the curvature of the cornea, can correct one eye for near vision, leaving the other eye untreated for distance vision.
Kamra inlay – The Kamra inlay is a small device surgically placed in the cornea to help the eye focus light. It is placed in one eye (the non-dominant eye), leaving the other untreated. The eyes work together to focus on objects at all distances.
