Cataract Clinical Trial
Official title:
Post-Implant Performance of the EC-3 IOL ADDENDUM TO THE PROTOCOL: Clinical Evaluation of the EC-3 Hydrophobic Acrylic Posterior Chamber Aphakic Intraocular Lens
The purpose of this study is to obtain data on the performance of the EC-3 lens at an interval of two years (and beyond) from subjects who were implanted. The primary aim of the study will be to evaluate the presence, if any, of PCO, lens glistening, and other anomalies in the subjects.
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.
