[A technical simplification of Barkan's goniotomy]

The Barkan goniotomy is more effective as the anterior chamber is longer maintained during the operation. The authors succeeded in good angular debridation, maintaining the chamber using a metilcelulosis solution from a 2 cc syringe and abandoning any other tubulature for infusion liquids. There were good results at 5 years, with lowering and the reducing of the corneal diameters, by a unique goniotomy.
