Presbyopia

Presbyopia is a vision condition in which the eye’s natural 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 changing its shape…. thicker to focus on near objects and thinner to focus on distant objects. When this ability is lost, presbyopia results.

Symptoms of presbyopia:

  • Blurry close vision that starts around the age of 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.  Only when the loss of elasticity impairs vision to a noticeable degree is the change realized. Presbyopia usually becomes noticeable in the early to mid-forties.

Diagnosing presbyopia:

A comprehensive examination will include testing for presbyopia. Your Vold Vision doctor will 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. Our doctors 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. Some presbyopic patients might try monovision or blended vision with contact lenses to allow them to see distance clearly in one eye and close-up clearly with the other eye. For patients who are presbyopic and have the beginnings of a cataract, Dr. Vold may recommend having a Refractive Lens Exchange which is similar to Advanced Cataract Treatment. With Refractive Lens Exchange surgery, Dr. Vold will remove your natural lenses that have become dysfunctional and replace them with one of the advanced IOLs such as the AcrySof ReSTOR IOL, TECNIS Multifocal IOL or Crystalens IOL that will provide you with a full range of vision from near to distance.

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