      Ophthalmic instrument alignment apparatus and method of using same

      An ophthalmic instrument for use with a subject's eye, comprising an interferometer having a test arm in which the subject's eye is to be positioned and a reference arm, the reference arm including a mirror adapted to be positioned such that the reference arm has a predetermined length, and an ophthalmic apparatus coupled to the interferometer such that, by altering a test arm length, a length between the ophthalmic apparatus and the eye is also altered. The mirror is positioned to achieve the predetermined length and a length of the test arm is adjusted such that interference between ...

    2. Customized corneal profiling

      A customized corneal profile is provided by combining corneal topography data with captured wavefront aberration data to form a course of refractive treatment of the eye. In one embodiment, the captured wavefront data is employed within the area of a pupil, while the corneal topography data is employed in the area outside of the pupil. In other embodiments, the topography data is adjusted based on the wavefront data, a course of refractive treatment is simulated and displayed upon the topography data, and an initial evaluation of the suitability of a patient for treatment is performed based on the topography data.

    3. Iris recognition and tracking for optical treatment

      A system and method are provided in which an iris or eye image is taken during a refractive diagnostic analysis. The image is employed for aligning data from the analysis with data from other refractive analysis instruments, as well as aligning a refractive surgical tool, such as a laser, with the eye for treatment. Further, the stored iris image is compared with the patient's iris before treatment, verifying that the correct eye is to be treated with a developed treatment pattern. A variety of refractive instruments can be used, such as corneal topography systems and wavefront aberration systems.

    4. System and method for predictive ophthalmic correction

      A system and method for providing a predictive outcome in the form of a predictive best instruction for a therapeutic ophthalmic correction of a patient's vision defects. The predictive best instruction is derived from prospective therapeutic-outcome-influencing, new information that is analyzed in conjunction with optimized, historical therapeutic-outcome information. The instruction is preferably an optimized, custom, photoablative algorithm for driving a photoablative, excimer laser. The instruction can be provided on a fee basis.

    5. Method and system for improving vision

      Methods and apparatus for improving vision incorporate the effects of biodynamical and biomechanical (biological) responses of the eye. The eye produces a biological response to trauma, such as a LASIK keratectomy or other necessary traumatic procedure in preparation for refractive surgery. By observing the biological response, a prospective treatment to correct higher order aberrations is adjusted to compensate for the biological effects. An improved photorefractive surgery system incorporates one or more suitable diagnostic devices that provide biological response information in such a manner that the patient need not change position from that assumed for the surgical procedure.

    6. Laser vision correction apparatus and control method

      A device readable medium for use in controlling a laser vision correction system includes a storage structure having stored therein a pre-programmed first, readable, corrective instruction reference that corresponds to an encoded customized corrective instruction determined by a calculation module external to the medium. The encoded customized corrective instruction is executable by a laser vision correction laser platform for correction of a refractive defect when the corrective instruction reference is properly recognized. A laser vision correction system including the device readable medium is described. A remunerative model relating to the device readable medium is disclosed.
