Intraocular lenses are eye implants used as surgical treatments to correct some very common eye problems. Due to great advances in medicine and technology, Intraocular Lenses are currently made from standard materials. Thus, these implants are very flexible, require no or a few stitches, and implementing them causes the least postoperative complications.
Intraocular Lenses Uses
Myopia, astigmatism, presbyopia, and cataract are all conditions in which the natural lens of the eye has some abnormality. Therefore, the vision will be affected and there will be troublesome sight problems interfering with normal daily activities. Intraocular lenses are the best solution to correct these abnormalities (in severe conditions).
These lenses come in different varieties with various characteristics that adapt to the needs of each patient.
ü "Phakic" intraocular implants (pIOL) for instance are used for the correction of strong myopia and hyperopia as well as defects inaccessible to LASER. There are mainly three different types of Phakic intraocular implants.
ü Bifocal implants: for correcting far vision and near vision or far vision and intermediate vision
ü Trifocal implants: for correcting far vision, intermediate vision, and near vision
With an intraocular implant, the visual result will be of good quality and the accuracy of the correction is remarkable.
A cataract is a serious condition in which the eye lens has become blurred and thus the vision is disturbed. In cataract surgery, the natural eye lens will be replaced with intraocular lens implants.
With cataract surgery, in most cases, we will no longer need glasses and thus gain comfort in doing everyday activities.
Why not laser surgery?
Myopia, astigmatism, and presbyopia, are all visual defects that can be corrected by some form of laser surgery such as LASIK. However, in severe conditions and for cataract problems, in particular, the best treatment to consider would be the replacement of the natural eye lens with an implant, that is intraocular lenses (IOL)
