We evaluated the opacification of posterior cap-sule after intraocular lens (IOL) implantation using quantitation study type Ⅱ. Objects of the study were 193 eyes treated by extracapsular cataract extraction with IOL implantation. A total of 24 types and sizes of IOLs were used.

Posterior capsular opacification developed in 12 eyes, 6.2%, of which 4 eyes had to be treated by capsulotomy. Incidence of posterior capsularopacification was greater in eyes with posterior synechia (33%) or with IOL 13 mm in diameter (21%) (p<0.05). Posterior capsular opacification was also positively correlated with the angle of haptics, diameter of optics, presence of pseudoex-foliation syndrome or corneal nubecula. In order to prevent posterior capsular opacification, it is essen-tial to use IOLs that would suppress proliferation of the lens epithelium either chemically or physically. Removal of the lens epithelium during surgery is also another contributing factor.
