An economical computer-controlled non-invasive
laser apparatus and method to perform anterior segment
surgery in an eye are disclosed. The
laser source may include a pumping
laser, a Nd:YAG laser cavity
gain media, a
stimulated Raman converter
crystal, intracavity
beam diameter-reducing
optics, and an intracavity Q-switching
crystal. The laser pulses have a selected
wavelength for anterior segment
surgery. A laser pulse delivery and treatment control mechanism and method for the practicing surgeon are also provided. The laser pulses and
delivery system may be used in anterior segment
surgery for
cataracts, where the laser pulses may be used to form the
capsulotomy, to form the corneal incision or to disintegrate contents of the
capsule before removal. The laser and
delivery system may also the used to treat a
capsule and lens for correcting or preventing
presbyopia and to treat a
cornea to correct visual deficiencies in an eye.
