Abstract: A full depth ophthalmic surgical system includes a femtosecond laser source and an optical coherence tomographer. The system is capable of performing surgical procedures along the entire length of the eye from the cornea to the retina. The optical system of the ophthalmic surgical system is optimized to focus the laser beam and imaging light in the vitreous humor of the eye. In some embodiments, the illumination light source and the scanning mirrors are imaged by the system's objective lens and the patient interface lens to locations near the pupil, to increase the volume of the vitreous humor reachable by the illumination light and laser beam. For procedures performed posterior to the lens, a method for calibrating the full depth ophthalmic surgical system is also provided. The system can be used to perform treatment in the vitreous humor, including treating floaters and liquification of the vitreous humor.

Abstract: The XYZ beam position of an ophthalmic laser system is calibrated by measuring a fluorescent signal induced by the focused laser beam in a thin glass coverslip via multiphoton absorption. A video camera measures the XY position and intensity of the fluorescent signal as the focused laser beam strikes the coverslip. The Z position of the focus is determined by scanning the targeted z position and identifying the Z scanner position of peak fluorescence. An OCT system measures the real space Z location of the coverslip, which is correlated with the Z scanner position. Other laser system parameters are assessed by repeatedly scanning a lower energy laser beam in a piece of IOL material, and observing damage (scattering voids) formation in the IOL material. Based on the rate of damage formation, laser system parameters such as beam quality, numerical aperture, pulse energy, and pulse duration, etc. can be assessed.

Abstract: A laser surgical method for performing a corneal incision while maintaining iris exposure below a predetermined exposure limit includes determining an initial iris exposure based on an initial treatment scan, determining whether the initial iris exposure is less than the predetermined exposure limit, generating a revised treatment scan comprising one or more treatment scan modifying elements when the initial iris exposure is greater than the predetermined exposure limit, and scanning the focal zone of a pulsed laser beam according to the revised treatment scan, thereby performing the corneal incision, wherein the one or more treatment scan modifying elements causes the iris exposure to be smaller than the predetermined exposure limit.

Abstract: 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.

Abstract: A method of altering a refractive property of a crosslinked acrylic polymer material by irradiating the material with a high energy pulsed laser beam to change its refractive index. The method is used to alter the refractive property, and hence the optical power, of an implantable intraocular lens after implantation in the patient's eye. In some examples, the wavelength of the laser beam is in the far red and near IR range and the light is absorbed by the crosslinked acrylic polymer via two-photon absorption at high laser pulse energy. The method also includes designing laser beam scan patterns that compensate for effects of multiphone absorption such as a shift in the depth of the laser pulse absorption location, and compensate for effects caused by high laser pulse energy such as thermal lensing. The method can be used to form a Fresnel lens in the optical zone.
