BACKGROUND: Excimer laser (VISX) photorefractive keratectomy was performed using nitrogen flowing through the ocular fixation ring. It was felt that eliminating nitrogen flow may provide faster early visual rehabilitation. METHODS: Two groups of 50 c

The surgical treatment of choledocholithiasis has traditionally relied on the exploration of the common bile duct. The advent of laparoscopic cholecystectomy now permits the surgeon direct access to the common bile duct. Currently, one fourth to one
