Presbyopia (Aging Eyes)

	Presbyopia makes it difficult to focus on close objects

Presbyopia, the most common eye condition in America, affects millions of people after age 40 and everyone to some extent by age 51.  Within the next 10 years, eye-health experts estimate 90 million baby boomers will have or will soon develop this age-related eye condition. 

Presbyopia is a vision condition in which the lens loses its flexibility, making it difficult to focus on close objects. During the early and middle years of life, the crystalline lens of the eye has the ability to focus both near and distant images by getting thicker for near objects and thinner for distant objects. When this ability is lost, presbyopia results.

Symptoms of presbyopia:

• Blurry close vision that starts after age 40
• Difficulty adjusting focus when switching from near to distance vision
• Eye fatigue along with headaches when doing close work

Causes of presbyopia:

• Age: As we age, the lenses in the eyes lose some of their elasticity, and without elasticity they lose some of their ability to change focus for different distances. Presbyopia may seem to occur suddenly, but the actual loss of flexibility takes place over a number of years. Long before an individual is aware that seeing close up is becoming more difficult, the lenses in the eyes have begun losing their ability to flatten and thicken. Only when the loss of elasticity impairs vision to a noticeable degree is the change recognized. Presbyopia usually becomes noticeable in the early to mid-forties.

Diagnosing presbyopia:

A comprehensive examination will include testing for presbyopia. Your eye doctor can conduct a refractive evaluation to determine whether your eyes focus light rays exactly on the retina at distance and near. A visual acuity test will determine your ability to see sharply and clearly at all distances. Your eye doctor will also check your eye coordination and muscle control, as well as your eyes' ability to change focus. All of these are important factors in how your eyes see.

Treatment of presbyopia:

Reading glasses and contact lenses are used by many for the temporary treatment of presbyopia. However, there are a number of vision correction procedures that can surgically reduce or eliminate the effects of presbyopia.

The first and only FDA approved procedure for presbyopia is NearVision CK (Conductive Keratoplasty).  In this treatment, radio waves gently strengthen the focusing power of the eye to give back the ability to read.  It is a painless, 3 minute procedure that is performed in the SureVision offices with just eyedrop anesthesia.  The results are immediate and lasting.  most people only need treatment of one eye to produce blended vision.   With blended vision you use both eyes to see together at all distances.

Some presbyopic patients like monovision, which allows them to see distance clearly in one eye and close-up clearly with the other eye.   The difference here is that each eye sees separately at different distances where blended vision has you seeing at all distances using both eyes.

Presbyopia can be present in combination with other types of refractive errors such as nearsightedness, farsightednes and astigmatism.
