    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. In one embodiment, the system uses a removeable focal point extension assembly to extend the reach of the focal point location of the laser beam to the vitreous humor of the eye. In another embodiment, 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. For procedures performed posterior to the lens, a method for calibrating the full depth ophthalmic surgical system uses the focal zone of the optical coherence tomographer beam as a proxy for the focal zone of the femtosecond laser source to. The system can be used to perform treatment in the vitreous humor, including treating floaters and liquification of the vitreous humor.

    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.

    Abstract: One embodiment is directed to a patient interface system for ophthalmic intervention on an eye of a patient, comprising: a housing; an optical lens coupled to the housing and having a focal axis; a eye surface engagement assembly coupled to the housing and comprising an inner seal having an inner seal diameter and being configured to circumferentially engage the eye, an outer seal having an outer seal diameter and being configured to circumferentially engage the eye, and a tissue migration bolster structure configured to be positioned circumferentially between the inner and outer circumferential seals and to prevent migration of tissue of the eye toward the eye surface engagement assembly when a vacuum load is applied within the assembly to cause vacuum engagement of the inner and outer seals against the eye.
