title: Results of a clinical trial of sodium hyaluronate in lens implantation surgery.
abstract: The results from a four-year clinical trial on the use of sodium hyaluronate (Healon) are presented. Six hundred three consecutive primary lens implantations were performed: 500 after extracapsular cataract extraction and 103 after intracapsular cataract extraction. The safety and efficacy of Healon were analyzed by examining postoperative ocular hypertension, uveitis, visual acuity, and endothelial cell loss. The results of the trial confirm that Healon is safe and effective and, provided it is not used in excessive quantities, free from serious side effects.
