Healon was the easiest and quickest to remove from the anterior chamber. Healon GV was also removed easily in a short time; however, in two patients very small particles of the iris pigment were mobilized by the Healon GV. Visco adhered to the intraocular structures and was difficult to remove from the eye; Methocel was difficult to remove from the corneal endothelium
