Armrest support for the slit-lamp delivery argon laser system.
We designed a new armrest for use at the argon laser. The arm support can be used on either the right- or left-hand side of slit-lamp tables of varying thicknesses. The continuous screw adjustment allows for easy height adjustment of the arm support. The construction of the armrest facilitates the adjustment and manipulation of a fundus contact lens, which is so necessary to the successful performance of argon laser photocoagulation.

A simple device to improve blinking.
A blink beeper was devised to remind patients with incomplete or infrequent blinking to blink completely and at normal intervals; the beeper worked by transmitting an audible tone every ten seconds through an earphone. In three postkeratoplasty patients, this simplistic approach not only resulted in a complete blink at regular intervals, but seemed to condition this response to continue when the blink beeper was taken away; this resulted in healing of large chronic epithelial defects. The blink beeper has also proved valuable in patients with either punctate epithelial erosions or those who wore hard contact lenses unsuccessfully because of infrequent or incomplete blinking.
