Characteristics and implantation of Maudgal compressible disc lens.
A 10 mm overall diameter one-piece compressible-disc lens was developed for in the bag implantation after cataract surgery performed by envelop technique or by phacoemulsification. The lens consists of an outer ring connected to a 6 mm diameter optical zone by two compressible loops. The loops and the outer ring are 10 degrees angulated with respect to the optic. The lens can be implanted through a 6 mm tunnel incision and a 5 mm diameter capsulorrhexis. In cadaver eyes, this lens was found to fit snugly in the capsular bag after implantation, leaving no room for decentration. The lens is also suitable for implantation in cases of anterior capsule radial tears. When sectorial zonulolysis is present, the introduction of this lens into the capsular bag stretches the detached bag to the periphery, thus facilitating the lens implantation.
