Anomalies include, but are not limited to:
Posterior Capsule Opacification (PCO) (pathological condition) - delayed clouding of the lens capsule after cataract surgery.
Glistenings - fluid-filled micro-vacuoles that form within the intraocular lens (IOL) optic when the IOL is in an aqueous environment. They may appear to be on the lens surface.
Artifacts - glares, halos, starbursts and/or shadows caused by IOLs.
Fibrosis - the formation of fibrous connective tissue, as in a scar.
Glare - undesirable sensation produced by brightness that is much greater than that to which the eyes are adapted. Causes annoyance, discomfort, or loss in visual performance.
Halos (symptom) - the appearance of hazy ring(s) around light.
