Secondary lens implantation.

A retrospective study is presented of a series of anterior chamber lens implantation in 64 eyes of 54 patients after an earlier cataract extraction. Best corrected final post-operative visual acuity was better or the same of best corrected pre-operative vision in 93.8% of eyes. Vision deteriorated significantly in 4 eyes, in 3 eyes cystoid macular oedema was suspected clinically, and in 1 because of open angle glaucoma. Patients requiring anterior vitrectomy had the least favourable outcome with retinal complications in 33%. Secondary lens implantation is safe. However, great caution is recommended for patients who will require anterior vitrectomy on account of the higher rate of retinal complications.
