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 intra‐capsular 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.
