Presbyopia And Treatments For Presbyopia Eye Care And Treatment Information

Presbyopia is an eye condition that will most likely happen to everyone to some degree over the course of a lifetime

. Presbyopia can be described as a difficulty in focusing on objects up close, best displayed by someone holding reading material at arms length to focus. Presbyopia can cause headaches and eyestrain when a person suffering from it is required to do their work close up.

As we age, the lens of the eyes loses its flexibility and becomes rigid, losing its ability to focus well. The exact cause of presbyopia is still unknown, but one theory is that the fibers in the lens become stiffened and are unable to change shape as well. Other factors that can cause presbyopia include trauma, occupation habits, and lifestyle choices. While there is no cure for presbyopia, there are a lot of procedures that can help correct presbyopia and allow improved near vision.

Different types of eyeglasses and contact lenses are available for the treatment of presbyopia. Reading glasses can be worn for work and reading done close up. Bifocal eyeglasses can improve both near vision and distant vision. Trifocals have three focusing points; one for near vision, one for immediate vision, and one for distant vision. Monovision glasses corrects near vision in one eye and distant vision in the other. The brain will then gradually adapt to using one eye for certain tasks depending on distance. These types of lenses can also be created as contacts.

Surgeries for presbyopia includes Laser assisted in situ keratomileusis, or LASIK, and Conductive keratoplasty, also known as CK. LASIK involves permanently changing the shape of the cornea in one eye allowing better near vision. CK uses a hand held probe to apply radio frequency energy at low levels to spots on the cornea, changing the eyes surface curvature improving focus.

Individuals who arent good candidates for LASIK can choose intraocular lenses, or IOLs as an alternative treatment. IOLs are similar to contacts, but are implanted to replace the eyes natural lens. There are three types of IOLs to treat presbyopia: ReSTOR, ReZoom, and crystalens. All will help presbyopic individuals see better at all distances.

To determine what treatment or method will work best for you, please visit an eye specialist to get a complete exam.
