Using a white rabbit model, the effect of the haptic portion of the intraocular lens (IOL) and intracapsular ring on the development of posterior capsular opacification (PCO) after extracapsular cataract extraction (ECCE) with phacoemulsification was studied. Implantation of both the intracapsular ring and IOL developed less PCO than implantation of the IOL alone. ECCE followed by implantation of the intracapsular ring alone also developed less PCO than ECCE alone. Through this experimental work in a rabbit model, it could be conceived that the haptic portion of IOL and the intracapsular ring can prevent the development of PCO.
