Presbyopia

Presbyopia is not a static condition but an evolutionary problem associated with reduced vision concerning nearby objects.

Causes of Presbyopia

 

presbyopiaPresbyopia normally occurs during the 40th to the 45th year of an individual's life. Usually the individual has difficulty focusing on various objects that are in close proximity, and everyday tasks such as reading a newspaper, looking at a computer screen, can lead to the feeling of pressure and weight in the eyes as well as increased headaches. Presbyopia is caused by changes to the lens within the eye.

TREATMENT:

 Prescription reading glasses. If you have no other vision problems, you can use glasses with prescription lenses for reading only. You will need to remove these when you're not reading.
Bifocals. These lenses have a visible horizontal line that separates your distance prescription, above the line, and your reading prescription, below the line.
Trifocals. These glasses have corrections for close-up work, middle distance vision — such as for computer screens — and distance vision. Trifocals come with two visible horizontal lines in the lenses.
Progressive multifocals. This type of lens has no visible horizontal lines, but has multiple powers for distance, middle distance and close-up corrections. Different areas of the lens have different focusing strengths.
Office progressives. These lenses have corrections for computer-distance and close work. You generally use these at a computer or for reading and remove them for driving or walking around.
Contact lenses
People who don't want to wear eyeglasses often try contact lenses to improve their vision problems caused by presbyopia. This option may not work for you if you have certain conditions related to your eyelids, tear ducts or the surfaces of your eyes such as dry eye.

 

Refractive surgery
Refractive surgery changes the shape of your cornea. For presbyopia, this treatment can be used to improve close-up vision in your nondominant eye. It's like wearing monovision( one eye seeing better for far and the other eye seeing beter for near) contact lenses. Even after surgery, you may need to use eyeglasses for close-up work.

Talk with your doctor about the possible side effects, as this procedure is not reversible. You might want to try monovision contact lenses for a while before you commit to surgery.

Lens implants

This is the preffered method of our doctor. This is called an intraocular lens replacement.

The simplest way to deal with presbyopia is with the use of presbyopic glasses (bifocal or multifocal) as well as the use of multifocal contact lenses. In cases where there is also a cataract that should be removed, the optimal solution is the implantation of a multifocal lens after surgical intervention. One of the main advantages of using multifocal intraoculars, compared to traditional single focal lenses, is the possibility of have better focus (long-intermediate-close) and not having to wear glasses.

Multifocal implants in no way affect the shape, and size of the eyes. They are not advised for individuals with retinal detachment (such as macular degeneration, detachment, etc.) though.

A placement procedure lasts only a few minutes (just 8-12 minutes for each eye) with the use of eye-drops for local anesthesia. With today's technology, the success rate from the insertion of a multifocal intraocular is extremely high. We must mention though, the end result does depends on the general condition of the eye.
