APPARATUS FOR OPHTHALMOLOGIC SURGICAL PROCEDURE USING FEMTOSECOND FIBER LASER

摘要

PROBLEM TO BE SOLVED: To provide an apparatus for fast refraction-correction ophthalmologic surgery in order to change the corneal curvature in a controlled way.

SOLUTION: The apparatus is composed of: a pulse laser device 110 having an optical fiber gain medium and giving a pulse repetition rate larger than 100,000 pulses per second and a per-pulse length of less than a few picosecond; and an optical path including a scanning head operably coupled to receive laser light 129 from the pulse laser device and operable to scan an output light pattern suitable to sculpt tissue for a surgical procedure using at least 100,000 pulses in less than 10 seconds.
