摘要： A system and method for improving the accommodative power of a focusing unit (e.g. an eye) involves increasing the flexibility of a first optical element in the unit (e.g. the cornea of the eye). Specifically, the needed flexibility is determined from diagnostic data, and the first optical element is structurally weakened according to the data. With this weakened structure (i.e. increased flexibility), the first element is better able to comply with configuration changes in a second optical element in the focusing unit (e.g. the lens of the eye). The consequence is, improved accommodation. For the present invention, the improved compliance to achieve optimal accommodation is accomplished either by performing appropriate LIOB on stromal tissue in the eye, or by application of a topical medium to selected areas on the anterior surface of the eye.

摘要： A device for establishing a desired alignment between a patient's eye and a laser system to facilitate an engagement therebetween includes a light source to illuminate the eye. A moveable platform is provided to move the patient relative to the laser system. To establish alignment between the eye and the laser system, a reference marker is based on the laser system. An image of the marker, along with reflections from the illuminated eye, is then transmitted to the system controller. There, the image and reflections are processed to determine a measured alignment that is then compared to the desired alignment. An error signal that is indicative of an alignment difference is then generated and used to incrementally move the platform, or the patient, in an appropriate direction.

摘要： A system for using a pulsed laser beam to process materials includes a selector for varying the pulse repetition rate of the laser beam. Also included is a control unit for identifying an optimal pulse repetition rate that is compatible with the required pulse energy level for processing the material. Variations in the pulse repetition rate can be made during a procedure pursuant to either pre-programmed instructions, or in response to closed loop feedback controls.

摘要： A comprehensive multi-mode system for performing ophthalmic laser surgery on selected tissue inside an eye includes a laser unit for generating and focusing a laser beam to perform Laser Induced Optical Breakdown (LIOB) at a focal point in selected tissue. Also included is a selector for defining an operational mode according to characteristics of the tissue to be altered by LIOB. In combination, the operational mode specifies value ranges for configuration parameters for a pulsed femtosecond laser beam, establishes a base reference datum in the eye, and identifies a scanning procedure for the focal point of the laser beam to customize the system for a particular surgical procedure. A computer that is connected to the laser unit is responsive to the selector for implementing the operational mode.
