An intraocular lens (IOL) is a lens implanted in the eye usually as part of a treatment for cataracts or for correcting other vision problems such as near-sightedness (myopia) and far-sightedness (hyperopia); a form of refractive surgery.
The lens is implanted in the eye's lens capsule, where the contractions of the ciliary body, which would focus the eye with the natural lens, are used to focus the implant, instead. [2] [38] IOLs used in correcting astigmatism have different curvature on two orthogonal axes, as on the surface of a torus: for this reason, they are called toric ...
A phakic intraocular lens (PIOL) is an intraocular lens that is implanted surgically into the eye to correct refractive errors without removing the natural lens (also known as "phakos", hence the term). Intraocular lenses that are implanted into eyes after the eye's natural lens has been removed during cataract surgery are known as pseudophakic.
The eye is usually patched on the day of surgery and use of an eye shield at night is often suggested for several days after surgery. [52] In all types of surgery, the cataractous lens is removed and replaced with an artificial lens, known as an intraocular lens, which stays in the eye permanently. Intraocular lenses are usually monofocal ...
People who have a multifocal intraocular lens after their cataract is removed may be less likely to need additional glasses compared with people who have standard monofocal lenses. [2] People receiving multifocal lenses may experience more visual problems, such as glare or haloes (rings around lights), than with monofocal lenses. [2]
Osteo-odonto-keratoprosthesis (OOKP), also known as "tooth in eye" surgery, [1] is a medical procedure to restore vision in the most severe cases of corneal and ocular surface patients. It includes removal of a tooth from the patient or a donor.
She underwent emergency surgery for lens removal due to severe injury to the lens and received a sutured IOL, which was specific for such cases. After 1 month, when the child came for follow up, it was found that there was a decenteration of the IOL. The parents had noted the child's difficulty in performing activities using the right eye.
The absence of this lens left the patient highly hyperopic (farsighted) in that eye. For some patients the removal was only performed on one eye, resulting in the anisometropia / aniseikonia. Today, this is rarely a problem because when the lens is removed in cataract surgery, an intraocular lens, or IOL is left in its place. [citation needed]
