A slit-lamp needling filtration procedure for uncontrolled glaucoma in pseudophakic and aphakic eyes.

In one aphakic and one pseudophakic patient without previous filtration surgery, a transconjunctival needling procedure similar to that used for failed filtration procedures was performed to create a filtering bleb. In both cases, intraocular pressure was successfully lowered for 6 months until the occurrence of bleb encapsulation, which was relieved by transconjunctival needling. There were no complications. In selected cases, this minimally invasive slit-lamp needling procedure provides successful filtration.
