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.

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 system includes a video camera with a tunable lens before it to image the entire length of the eye. 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: A narrow angle illumination light source for an ophthalmic surgical laser system includes multiple light emitting diodes (LEDs), multiple corresponding ball lenses, multiple corresponding upper apertures located between the LEDs and the lenses (optional), and multiple corresponding lower apertures located below the lenses. The light passing through each upper aperture and corresponding lens forms a light cone having a defined divergence angle and cone axis angle; the light cone only illuminates the corneal and sclera of a docked eye without illuminating the patients nose and orbit. The lower apertures may have distinctive shapes to aid video focusing. The multiple LEDs are distributed uniformly in the circle, and may be divided into multiple independently controllable segments which allows directional illumination. The LEDs also have controllable brightness to allow images of darker and brighter illuminations to be taken in short succession.

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.
