Title: Soft translating contact lens for presbyopia
Inventor: ZHANG XIAOXIAO
IPC: G02C7/04
Filed: 2001-08-16
Abstract: A contact lens has an optical zone with a distance vision zone and a near vision zone. The distance vision zone also has a first area that is sufficie nt to overlay a substantial portion of a pupil of a user and is disposed in a first position within the optical zone so that the user's pupil is substantially subtended by the distance vision zone when the user is gazing at a substantially horizontal point. The near vision zone is substantially concentric with the rotational axis and extends radially outward from the distance vision zone. The near vision zone has a second radius of curvature that provides near vision correction and has a second area that is sufficien t to overlay a substantial portion of the pupil of a user. The near vision zon e is disposed in a second position within the optical zone so that the user's pupil is substantially subtended by the near vision zone when the user is gazing at a near vision point below the substantially horizontal point. A ridge zone enables engagement with a lower eyelid of a user so as to provide  vertical translation support, and a transition zone provides a smooth transition from the ridge zone to the optical zone.

Patent CA-2455607-A1 (CA)
Inventor: LEBO ROGER V
IPC: C12Q1/68
Filed: 2002-07-09
Abstract: Independently assaying a control sequence for each modified DNA  sequence tested by a single laboratory assay of individual genomic DNAs optimizes molecular test accuracy. To minimize control assay complexity and cost and optimize accuracy, this application teaches the selection and synthesis of four or more control sequences on one or more DNA fragments that are sufficiently long to be tested by the selected test format. Synthesized controls with many tested sequences are superior to controls selected from individual DNAs with unpredictable, limited, randomly occurring mutations and polymorphisms that must be obtained, identified, selected, added and tested using more complex strategies. All desired controls are readily synthesized from polynucleotide sequences using artificially synthesized primers with modified nucleotide sequences and flanking primers to extend the sequence length between the primer sites on template polynucleotides that can all be derived from a single normal individual's sample.
