Abstract
An environmental chamber that can be fixed to the eye during laser refractive surgery. The chamber is held in place by a suction ring or the like and contains a window that is transparent to necessary ultraviolet radiation, visible light and infrared radiation wavelengths. The chamber is connected to a control system that controls the temperature and humidity within the chamber and provides for the evacuation of ablation by-products from the surgical site.
Claims9
A chamber for laser refractive surgery, comprising:
- a) a housing having an interior;
- b) a suction ring attached to the proximal end of the housing, the suction ring adapted to seal the housing on an eye;
- c) a window on the distal end of the housing opposite the suction ring, the window sealing the distal end of the housing;
- and
- d) an environmental control system in communication with the interior, the control system capable of maintaining desired environmental conditions in the interior.
