Your eye contains a specific elastic protein that is responsible for the rapid ability of your lens to change shape. This is how your eye focuses. The elasticity of this protein pulls and relaxes around the perimeter of the lens, causing it to stretch or relax. The change in the lens’s shape is responsible for our ability to see far away and close within a fraction of a second. As we age, the lens elasticity decreases and focusing ability decreases as well. Most of us notice this change when we try in vain to focus on a prescription bottle, a magazine, or a book and cannot make the words come into focus. This condition is called presbyopia (literally “old eyes”) and affects more than a billion people around the world. How does this relate to needing readers? The Orlando ophthalmology experts at Magruder Laser Vision explain.
Less than 30 years ago, Americans had no choice when their vision became presbyopic; their doctors prescribed “readers,” or bifocals, to correct their vision. Doc Brock and the staff at Magruder Laser Vision want you to know that this condition is now treatable with a number of outpatient vision correction procedures that will make your life easier. Treatments may include KAMRA corneal inlay, LASIK, PRK, or refractive lens exchange. The first – KAMRA is the latest procedure specifically designed for people suffering from presbyopia. Knowing the health and structural integrity of your eye will determine which of these Orlando ophthalmology procedures is the correct one for you.
This is probably a procedure you are not familiar with because it is quite new. Working much like the lens of a camera (hence the name), this cutting-edge device controls the amount of light entering your eye and focuses it to give you enhanced visual clarity. This allows a greater focal range so you can see both distant and near objects without difficulty. Patients between the ages of 45 and 60 who have stable far vision but trouble seeing close up are the best candidates for this procedure.
LASIK is available for nearsighted, farsighted, astigmatic, and presbyopic patients. By changing the shape of the eye, the focal plane, which is too short in myopia and too long in hyperopia, is redirected to the fovea in the back of the eye where sharp vision is most easily recognized.
Photorefractive keratectomy is quite similar to LASIK except the laser focuses on the surface of the cornea rather than behind it. Recovery from PRK may be longer than LASIK recovery, however. PRK is well suited for military personnel and athletes with nearsightedness, farsightedness, astigmatism, and presbyopia.
In this procedure, the natural lens is replaced with an intraocular lens that has your prescription. Similar to cataract surgery, refractive lens surgery is a good choice for people with nearsightedness, farsightedness, or presbyopia. A multifocal intraocular lens allows patients to see a broad range of vision under many different lighting conditions and is preferred for close-up vision. An accommodating intraocular lens is more specific to far vision, and monovision correction has one focusing distance; your physician may recommend monovision correction with one eye focusing on far objects while the other eye accommodates near vision.
