Large soft contact lenses in the management of leaking blebs

To investigate the efficacy of a new large permanent wear soft contact lens in the management of leaking blebs following trabeculectomy. Twenty-four patients with leakage from a trabeculectomy bleb, both fornix based and limbal based, with and without mitomycin adjuvant, were treated with a 78% water content soft contact lens of 17.5 mm diameter, fit according to each patient's keratometry readings. The leakage from a conjunctival trabeculectomy bleb was successfully treated in 22 out of 24 patients. The 17.5 mm 78% water content permanent wear soft contact lens is a preferred method of management of leaking blebs when specifically tailored to the patient's corneal curvature.
