New posterior chamber lens with open circular haptic for a small capsular opening: preliminary report

This report describes a single-piece poly-(methyl methacrylate) posterior chamber lens for implantation through a small capsular opening. It has open circular loops with an eyelet at each loop end. The optic is 6 mm in diameter and the overall diameter of the intraocular lens (IOL) is 11 mm. The lens diameter can be reduced to 7 mm by grasping the eyelets at both open loop ends with a specially designed holding forceps. The IOL is inserted in the capsular bag after circular capsulorhexis or through a linear capsulotomy in the intercapsular technique. This IOL is adaptable to a small capsular opening and maintains the usual shape of the capsular bag, similar to a disc lens.
