20130282115 | DUAL-FILTER OPHTHALMIC LENS TO REDUCE RISK OF MACULAR DEGENERATION - An improved dual-filter lens for protective eyewear that combines a first filter for blocking essentially 100% of UV light, and second filter for filtering blue light. The first filter may comprise a multi-layered dielectric mirror layer 14 or Rugate filter 50, and the second filter may comprise dye-impregnated lens layer(s) 16, 18 or Rugate filter 50. The first filter blocks essentially 100% of UV light, while the second filter establishes an increasing transmission profile that cuts on sharply at approximately 415 nm, and establishes an increasing transmission profile between approximately 415 nm to about 475 nm. The cut-on slope rises approximately 0.15% in transmissivity for every nanometer of increasing wavelength change, with a maximum filtering effect within the 440-465 nm range. These dual filters provide a balanced light transmission profile that reduces harmful tight transmission and prevents macular degeneration, cataracts and other ocular injuries, while still preserving visual acuity. | 2013-10-24 |
20130282116 | APPARATUS, SYSTEM AND METHOD TO ACCOUNT FOR SPHERICAL ABERRATION AT THE IRIS PLANE IN THE DESIGN OF AN INTRAOCULAR LENS - The present invention includes at least an intraocular lens, and a system and method of customizing at least one characteristic for an intraocular lens, in accordance with a regression that indicates the postoperative spherical aberration at the iris plane of a patient aphakic eye, in order to obtain a desired postoperative condition. The lens, system and method of customizing at least one characteristic of an intraocular lens may include measuring at least one biometric parameter of an eye at a desired light level, determining a desired postoperative condition of the eye, obtaining a corneal spherical aberration and an anterior chamber depth of the eye, and empirically calculating a spherical aberration at an iris or pupil plane of the eye, based on a regression formula comprising at least the corneal spherical aberration and the anterior chamber depth, and cross products thereof. | 2013-10-24 |
