title: Experiences with implantations of the semiflexible McGhan/3M, style 70 anterior chamber lens.
abstract: A non-selected group of patients totalling 174 eyes without contraindicating eye diseases had the semiflexible McGhan/3M, style 70 anterior chamber lens implanted as either a primary or a secondary procedure following intracapsular cataract extraction via a corneal incision. Three patients simultaneously underwent a penetrating keratoplasty. Vitreous loss and/or rupture of lens capsule did not contraindicate the lens implantation, and anterior vitrectomy was always performed when vitreous loss occurred. Initially lens implant diameter was calculated too high, causing a lens axial corneal astigmatism in 11 patients. In the remaining patients a reduced anterior chamber lens diameter was used, and corneal astigmatism was accordingly comparable to those of non-anterior chamber implanted controls and did not differ significantly. Technical problems experienced in the procedure are reported and discussed. None of the implants had to be removed due to complications.
