Abstract: A system/method allowing hydrophilicity alteration of a polymeric material (PM) is disclosed. The PM hydrophilicity alteration changes the PM characteristics by decreasing the PM refractive index, increasing the PM electrical conductivity, and increasing the PM weight. The system/method incorporates a laser radiation source that generates tightly focused laser pulses within a three-dimensional portion of the PM to affect these changes in PM properties. The system/method may be applied to the formation of customized intraocular lenses comprising material (PLM) wherein the lens created using the system/method is surgically positioned within the eye of the patient. The implanted lens refractive index may then be optionally altered in situ with laser pulses to change the optical properties of the implanted lens and thus achieve optimal corrected patient vision. This system/method permits numerous in situ modifications of an implanted lens as the patient's vision changes with age.

Abstract: An ophthalmic laser treatment system and method providing for a liquid optical interface (LOI) with a patient eye surface (PES) using an elliptical ocular suction ring (OSR) is disclosed. A disposable ocular patient interface (OPI) provides for simultaneous differential vacuum mating of the PES, OSR, OPI, and an optical window retainer (OWR). The PES, OSR, OPI, and OWR form an enclosed volume in which liquid may be interjected to cover the PES during laser treatment. A vacuum suction pump (VSP) provides controlled vacuum to the OPI ensuring proper differential vacuum mating (DVM) between the PES, OSR, OPI, and OWR during laser treatment. The OWR connects to a laser objective bracket (LOB) via an ocular force sensor (OFS) and an optical separator bracket (OSB). The OFS senses applied pressure to the PES and provides data to a computerized control device (CCD) that limits applied pressure to the PES during laser treatment.

Abstract: A system/method allowing intraocular lens (IOL) fabrication using a femtosecond laser is disclosed. The system and method generate a stream of pulses at a rate of at least 1 million pulses per second and a pulse length of 300 femtoseconds or less to sculpt a polymeric material blank (PMB) to form an IOL. The high repetition rate and short pulse length combine to permit IOL fabrication in less than 10 minutes. During this fabrication procedure a lens may be formed within the IOL by incorporating a refractive index shaping (RIS) structure within the IOL. Additionally, IOL haptics may be formed during this IOL formation process. This combination of physical feature generation and RIS structure generation permits per-patient customization of the IOL as it relates to sphere, cylinder, asphericity, multifocality, and/or higher optical aberrations (HOAs).

Abstract: A lens for placement in a human eye, such as intraocular lens, has at least some of its optical properties formed with a laser. The laser forms modified loci in the lens when the modified loci have a different refractive index than the refractive index of the material before modification. Different patterns of modified loci can provide selected dioptic power, toric adjustment, and/or aspheric adjustment provided. Preferably both the anterior and posterior surfaces of the lens are planar for ease of placement in the human eye.

Abstract: A system and method for determining the shape of a cornea of an eye illuminates at least one of the interior surface, the posterior surface, and the interior region of the eye with infrared light of a wavelength that can generate fluorescent light from the portion of the cornea illuminated. The generated fluorescent light is then detected. The step of illuminating can comprise focusing the infrared light in a plurality of different planes substantially perpendicular to the optical axis of the eye. From the detected light it is possible to create a map of at least a portion of the interior surface, at least a portion of the posterior surface, and/or portion of the interior region of the cornea. Clarity of vision can be determined by generating autofluorescence from proteins in the pigment epithelial cells of the retina.

Abstract: A system and method for altering the shape of a lamina of transparent material (e.g. the cornea of an eye), as it is being subjected to a transverse pressure differential, requires a computer controlled laser unit. In accordance with specified input parameters, the computer directs the laser unit to perform LIOB over predetermined surfaces within the lamina. This weakens the material for a desired reshaping of the lamina in response to the pressure differential. With respect to a perpendicular axis that is defined by the lamina, surfaces parallel to the axis (e.g. cylindrical surfaces) are separated from each other by about two hundred microns. For surfaces perpendicular to the axis, the separation is about ten microns. In each instance, the cuts that result from LIOB are only about two microns thick.
