摘要: A device for isolating a lenticle in the cornea of an eye. The device includes: a laser beam source to emit pulsed laser radiation having a pulse frequency of 1.2 MHz to 10 MHz, a pulse energy of 1 nJ to 200 nJ and a wavelength penetrating the cornea; a beam-forming unit having beam optics with an image field and that bundles pulsed laser radiation into a focus located inside the image field, and which has a maximum diameter of less than 3 μm; a beam-deflection unit shifting the focus in the cornea and inside the image field, the focus moving along a path when the image field is resting; and a control unit to control the source and the beam-forming unit to isolate the lenticle by specifying the path. The lenticle is delimited by a cut surface which is curved with regard to a front surface of the cornea.

摘要: Methods and apparatus to improve or restore vision by causing a rebooting of the visual system of an eye with modification of visual search, sampling and stimulation away from the preferred retinal locus of fixation of an eye to enhance neural integration and perception of visual information from within the field of view are described herein. Some embodiments cause transient, reversible or repeatable redirection of environmental light away from the preferred retinal locus of fixation of an eye to multiple retinal locations that are not the preferred retinal locus of fixation. Some embodiments reduce exposure of environmental light at the preferred retinal locus of fixation of an eye for a determinable interval at a determinable rate. Some embodiments cause a defocusing of environmental light at the preferred retinal locus of fixation in an eye with a visual impairment or loss.

摘要: Methods and related apparatus for real-time process monitoring during laser-based refractive index modification of an intraocular lens. During in situ laser treatment of the IOL to modify the refractive index of the IOL material, a signal from the IOL is measured to determine the processing effect of the refractive index modification, and based on the determination, to adjust the laser system parameters to achieve intended processing result. The signal measured from the IOL may be a fluorescent signal induced by the treatment laser, a fluorescent signal induced by an external illumination source, a temporary photodarkening effect, a color change, or a refractive index change directly measured by phase stabilized OCT.

摘要: Transcorneal and fiberoptic laser delivery systems and methods for the treatment of eye diseases wherein energy is delivered by wavelengths transparent to the cornea to effect target tissues in the eye for the control of intraocular pressure in diseases such as glaucoma by delivery systems both external to and within ocular tissues. External delivery may be affected under gonioscopic control. Internal delivery may be controlled endoscopically or fiberoptically, both systems utilizing femtosecond laser energy to excise ocular tissue. The femtosecond light energy is delivered to the target tissues to be treated to effect precisely controlled photodisruption to enable portals for the outflow of aqueous fluid in the case of glaucoma in a manner which minimizes target tissue healing responses, inflammation and scarring.

摘要: In certain embodiments, an ophthalmic surgical system for adjusting a dimension of an eye includes a camera and a computer. The camera generates a surgical image of the eye in contact with a patient interface, which distorts the cornea. The surgical image includes the pupil with a real pupil diameter. The computer accesses a diagnostic image of the eye with the cornea having a natural curvature. The natural curvature affects the real pupil diameter to yield a diagnostic pupil diameter of the diagnostic image that is different from the real pupil diameter of the surgical image. The computer adjusts the real pupil diameter of the surgical image using an eye model to yield a refracted pupil diameter that takes into account the curvature of the cornea and uses the refracted pupil diameter to compensate for the difference between the diagnostic and real pupil diameters.
