摘要
An electronic SLO/OCT ophthalmoscope is equipped with a femtosecond (fs) laser for intra- or preretinal therapeutic use in the posterior segment of the eye. In one application the retina photoreceptor mosaic or Bruch's membrane is disrupted in such pattern that minimizes loss of visual functioning but reduces metabolic load of the outer retina. Using a beam splitter, one embodiment combines the SLO/OCT scanning beams with the therapeutic fs beam and an aiming beam. The therapeutic channel uses an independent x/y positioner and micro-deflector. Because the duty cycle is appropriate, a second embodiment can use the SLO/OCT scanners to also simultaneously scan a modulated therapeutic laser beam. A biometric OCT probe can be integrated in both configurations for focusing purpose.;Another embodiment can selectively and systematically disrupt or ablate the vitreous body of an eye in a predetermined (programmed) 3-D pattern that minimizes the risk of inadvertently damaging the retina or anterior segment of the eye.
