IOL
Intra-Ocular Lens: A small optical lens implanted inside the eye, typically as a part of modern cataract surgery. Without IOL implantation, very thick “coke-bottle” lenses would be necessary to restore vision. With IOL implantation, it is possible not only to clear up the blurring and distortion caused by the cataract, but also to correct any existing refractive error (nearsightedness, farsightedness, etc.).
