A lens made of plastic or other synthetic material used to replace an abnormal eye lens, as in the removal of a cataract.
An artificial lens implanted inside the eye.
Artificial lens implanted into the eye after surgical cataract removal to replace the cataract-damaged natural lens.
An artificial lens for the eye, implanted in the eye’s capsule after surgical extraction of the cloudy lens (cataract).
An artificial lens made of acrylic or silicone; the lens may be placed posterior to the iris (PCIOL) or anterior to the iris (ACIOL). Posterior chamber lens may be mono-focal or multifocal and can also correct an astigmatic error. A lens is removed because of abnormalities such as cataracts. If the original lens capsule is present and an IOL is placed inside it, the surgical procedure is called posterior chamber IOL implantation. If the capsule has been removed in a previous surgical procedure, the IOL may be placed in front of the iris, directly adjacent to the cornea. This is called anterior chamber IOL implantation. In another procedure, the IOL is implanted behind the iris. Which method of IOL implantation produces the best results is being investigated.
An artificial lens, typically composed of silicone or plastic, implanted inside the eye. It is utilized for corrective purposes.
