Paper Abstract

This study was to determine the feasibility and reproducibility of laser welding of cornea with a CO2 laser system capable of real times infrared fiberoptic radiometric control of tissue temperature. A fiberoptic radiometric temperature control system for the CO2 10.6 micrometers laser was developed that enabled a real time nontactile temperature measurement of welding surface. The system was tested on the cornea in 40 in vitro bovine eyes, and also in 6 in vivo corneas of rabbit eyes. Welds performed at a set point temperature of 65 degree(s)C, with or without adjuvant 50% albumin solder. Leaking pressure, surgical time and histologic evaluation were determined for welding and for suturing controls of 6 mm central corneal perforating cuts.
