Appliance for treatment of glaucoma controls treatment beam based on measurement beam reflected light from Schlems canal

摘要

In addition to the light UV laser (8) for treating the glaucoma second UV source (11) is provided as a measurement light having a wave length which is clearly different from that of the treatment laser. The second beam passes through a partly transparent mirror (10) to be reflected by a second mirror (9) into the treatment catheter (4). Based on the light reflected back from the Schlems canal to a detector (12) a computer (13) automatically controls the main laser according to the treatment stage reached.
