The author reports on experience gathered in retinal detachment surgery in 7 of his own cases with intraocular lens implants. The paper deals with pre-operative diagnosis, intraoperative management and xenon or argon laser coagulation. It is pointed out that the image quality of the intraocular lens implants needs to be improved for successful diagnosis at the periphery of the fundus. After 7 episcleral buckling procedures (Custodi's technique) and 2 encircling procedures (Schepens) reattachment was accomplished in all 7 cases. The detachment surgery in these cases was more difficult than in eyes without intraocular lens implants, not least as a result of the poor image quality of the artificial lenses.
