Not every patient is a good candidate for the presbyopic intraocular lenses.
Your physician will discuss with you the appropriateness of these based on your individual visual needs and on your eye examination. Accommodating IOLs are also designed to provide a continuous range of vision for distance, intermediate, and near, eliminating or reducing patients’ dependence on reading glasses or bifocals.
As the internal muscles of the eye contract during periods of reading, the visual portion of the lens is moved forward shifting ones’ focus to the near tasks.
With the latest advances, having clear vision at only one distance is no longer the only option.
Presbyopic IOL technology can not only correct impaired distance vision, but also maintain the eye’s focusing power for reading and computer work.
The second type of IOL, more commonly known as a phakic intraocular lens (PIOL), is a lens which is placed over the existing natural lens, and is used in refractive surgery to change the eye's optical power as a treatment for myopia, or nearsightedness.
Most IOLs fitted today are fixed monofocal lenses matched to distance vision.
These developments include presbyopia-correcting IOLs which provide a treatment option for presbyopic patients who do not qualify for laser refractive surgery and do not want to rely on reading glasses.
