ABSTRACT
The problems originating in sulcus implantation of posterior chamber intraocular lenses in the late 1970s and early 1980s caused the members of today’s American Society of Cataract and Refractive Surgery (ASCRS), to discuss and favor the idea of intraocular lens (IOL) implantation into the capsular bag to achieve a better centration of the implants and accordingly a reduction of postoperative complications. The Simcoe loops (modified C-loop), a new design of that time, provided a considerable improvement in intracapsular centration compared to the generally used J-loops. However, decentration remained common.
