ABSTRACT:
A posterior chamber intraocular lens is usable as an implant in patients having both cataracts and glaucoma. The lens includes an optic portion which is capable of performing the focusing function of a human lens. Two haptics are connected to the optic. At least one of the haptic includes a blocking segment. The blocking segment has a length and width sufficient to prevent tissue posterior to a trabeculectomy fistula from occluding the fistula. The blocking segment thus creates a barrier to prevent the posterior chamber and other eye structures from interferring with proper drainage of aqueous humor from an eye.
