Lens implantation combined with trabeculectomy.

The results in seventeen cases of combined trabeculectomy and posterior lens implantation after extracapsular surgery are presented with a follow-up of three to 17 months. The mean reduction of intraocular pressure was 13 mmHg. There was no relationship between the histological localisation of the filter site and the effectiveness of the operation. As the postoperative inflammation is increased as compared to simple lens implantations, a combined operation is only indicated where no alternative to a filtering operation is possible. The use of an iris suture after iridotomy will prevent a later retraction of the iridectomy limbs.
