Abstract
A compact excimer laser system is provided that includes argon fluoride laser gas, electronic, and laser head all compactly arranged such that the patient bed can rotate over all of these components. This allows the patient bed to be rotated for easy egress of the patient without striking the head against an optical extension through which the excimer laser is fired onto the patient's eye. Further, an automated lamellar keratoplasty system is incorporated into the electronics and components of the laser system so that laser in situ keratomileusis can be easily performed.
Claims19
A system for laser eye surgery, the system comprising:
- a laser head for providing a laser beam suitable for removing tissue from an eye;
- a power supply connected to the laser head for powering the laser head;
- an aiming system for providing an optical path from said laser head and for aiming the laser beam along the optical path to the eye, said aiming system further comprising:
- a final beam directing portion extending horizontally over a patient in an operational position, the final beam directing portion directing the laser beam substantially perpendicular to the patient's eye when the patient is in the operational position;
- a patient bed positioned rotatably below the final beam directing portion, said patient bed rotatable from a first position wherein the patient is in the operational position below said final beam directing portion, to a second position in which the patient is moved away from below said final beam directing portion, whereby the patient can easily sit up without striking his or her head against the final beam directing portion.
A laser system for performing laser in situ keratomileusis, the laser system comprising:
- a laser head providing a laser beam for ablation of stromal tissue;
- an aiming system providing an optical path from said laser head for the laser beam and for aiming the laser beam along the optical path to the eye;
- a computer system coupled to said aiming system and said laser head, said computer system controlling the firing of said laser head and the aiming system and displaying data on a display, said computer system coupled to said automated lamellar keratoplasty system and displaying vacuum and power data from said automated lamellar keratoplasty system;
- an integrated automated lamellar keratoplasty system comprising:
- a vacuum source for vacuum port for providing a vacuum to a microkeratome source
- a power source for providing power to a port for providing power to the microkeratome.
A compact laser surgery system comprising:
- a patient bed enclosure with a patient surface and a patient height, said patient bed enclosure surrounding an open space;
- a laser gas container disposed in said open space towards a first side of said patient bed;
- an electronics package for providing computer control disposed in said open space adjacent to said laser gas container towards a second side of said patient bed;
- a laser head located adjacent to said patient at a height less than said patient height, said laser head connected to laser gas container for receiving laser gas and connected to said electronics for receiving power.
