title: Quality control, and changing indications for lens implantation. The Seventh Binkhorst Medal Lecture-1982.
abstract: A total of 776 specimens yielded significant data on quality control and manufacturing defects in lens implants and on the biodegradation of lens implant and suture materials. Improved quality and an understanding of durability of materials in vivo has permitted wider safe use of intraocular lenses.
