Trabeculectomy, cataract extraction and intra-ocular lens implantation.

Seventeen cases of open-angle glaucoma requiring cataract extraction underwent intracapsular cataract extraction, trabeculectomy posterior to the scleral spur, and MK9 intraocular lens insertion. Approximately 50 per cent of the patients achieved intraocular pressures of 18 mm Hg or less without medication two years later. Though implantation reduces the surgical success of the combined operation, it is safe, easy to perform and does not worsen pre-operative levels of intraocular pressure and/or control.
