20090160075 | METHODS FOR FABRICATING CUSTOMIZED INTRAOCULAR LENSES - In one aspect, the present invention provides methods for custom fabrication of IOLs. In some embodiments, such methods call for measuring one or more aberrations of a patient's eye, and determining the profile of at least one surface of an IOL that would ameliorate, and control those aberrations. The surface profile can then be imparted to a surface of a starting lens (or a lens blank) via ablation, e.g., by utilizing an excimer laser beam. In some other embodiments, the measured aberrations can be utilized to determine the profile of at least one surface of a wafer mold. A wafer mold having that surface profile can then be fabricated, e.g., by ablating a slab or an existing wafer of appropriate material, and the mold can be used to fabricate an IOL suitable for implantation in the patient's eye. | 06-25-2009 |
20090230580 | Systems and Techniques for Reducing Group Delay Ripple in a Dispersion Compensating Grating - A technique is described for reducing group delay ripple in a fiber dispersion compensation grating. The grating is mounted into a trimming setup that includes a trimming device and a scanning assembly for causing a region of the grating to be scanned along its length by the trimming device output. The grating is sensitive to the trimming device output, such that exposure to the trimming device output causes a change in the effective refractive index of the scanned region, the amount of change varying as a function of scanning velocity. A region of the grating to be trimmed is selected, and a scanning velocity profile is programmed into the scanning assembly that is calculated to modify the effective refractive index of the selected grating region along its length so as to smooth out group delay ripple in the selected grating region. | 09-17-2009 |
