title: Preliminary report on the rigid disc lens.
abstract: Theoretically, a circular and lenticular implant is the most appropriate for implantation in the capsular bag. Various prototypes have led to a single-piece model in polymethylmethacrylate with a bioconvex 7-mm optic and a 9-mm total diameter. This so-called disc lens has been implanted in 61 eyes. The longest follow-up is 18 months. Thus far, the clinical results are excellent. It appears that this 9-mm disc lens permits centration without acting as a spring in the capsular bag. A large mydriasis and the use of viscoelastic material are mandatory for inserting the rigid disc lens. A circular implant appears to be an advance in IOL design adapted to the capsular bag configuration. A greater number of cases and longer follow-up are necessary to evaluate the rigid disc lens.
