A first year's experience with intraocular lens implantation.

A microsurgical modification of Binkhorst's "open sky" technique of extracapsular cataract extraction was developed for intraocular lens implantation. Clear visualization of both anterior and posterior capsule is stressed and risky aspiration is minimized. Thirteen cases operated upon in the first year are described. Synechiae to the haptics occurred when mydriasis was not prompt. All but one obtained useful naked acuity. Binocularity depended chiefly upon the acuity of the opposite eye. Pre-calculation of lens power reduced the spread of postoperative refractive errors although deviation was greater than expected and myopia overaccentuated. High astigmatic errors occurred in three patients.
