Abstract
A method for determining the propensity of an intraocular lens material to prevent posterior capsule opacification is disclosed. The method involves incubating replicate samples of an IOL material with collagen IV, washing off any loosely bound collagen IV. Following the washing step, one sample is counted to determine the amount of collagen IV that remains adhered to the IOL material. A second sample is further processed prior to counting by subjecting it to a desorption step and a further washing step.
