| 20090303442 | CORNEAL AND EPITHELIAL REMODELLING - This invention relates to methods of shaping the anterior surface of the eye for controlling the progression of refractive error of the eye, in particular, myopia. The method employs the fitting of orthokeratology lenses having a precisely shaped posterior surface adapted to accurately shape the peripheral region of the eye. The method includes the steps of assessing central and peripheral refractive error parameters for the eye, determining the optimal anterior surface profile for the eye, including at both the optical centre of the cornea and at a selected optical periphery of the cornea, which would result in a desired refractive correction to achieve good vision for the eye and the desired peripheral refraction (curvature of field) for the eye for controlling progression of myopia. Accurate measurement of the shape of the pre-treated eye is important, thereby enabling a corresponding lens profile to be designed or selected so that the treatment process achieves a post-treatment peripheral profile which optimally focuses peripheral rays anteriorly of the retina, thereby controlling the progression of myopia. The invention extends to a lens manufactured so as to optimally treat the peripheral region of the eye. | 12-10-2009 |
| 20100225883 | CHARACTERISING EYE-RELATED OPTICAL SYSTEMS - An instrument and method for characterising eye-related optical systems, including the live human eye involves scanning an illuminating light beam from a light source and light detector unit from element to element of a beam deflector array of elements arranged laterally across the optical axis of eye. At each successive element the illuminating beam is deflected to form an interrogating beam that is directed into the eye at a peripheral angle that depends upon the lateral location of the deflector element. A return beam is reflected or back-scattered from the cornea and returned via the same deflector element to the light source and detector unit. This allows the interrogating beams to be scanned sufficiently rapidly into the eye to greatly reduce the variation of eye fixation and gaze that accompany other methods of measuring peripheral refraction or aberration of a natural eye. In addition to or instead of scanning the illuminating beam over each element of the array, all or multiple elements of the array can be illuminated simultaneously and the multiple interrogating rays thus generated can be gated by the use of an LCD aperture plate. Alternatively, an LCD aperture plate can be interposed between a wide illuminating beam and operated to selectively illuminate the beam deflector | 09-09-2010 |
| 20110051079 | MYOPIA CONTROL MEANS - Sets, kits or stocks of anti-myopia contact or spectacle lenses, along with methods for their use, that do not require a clinician to measure peripheral refractive error in the eyes of myopic patients. Extensive surveys have shown that lenses having peripheral powers or defocus set in accordance with central corrective power will cover almost all normal myopes not worse than −6D central refractive error. In one example, a kit or set of lenses ( | 03-03-2011 |

| 20090122264 | Methods and Apparatuses for Enhancing Peripheral Vision - Methods and apparatuses are disclosed for improving peripheral vision by positioning the peripheral image points at a pre-determined and precise position relative to the retina to achieve optimal performance according to one or more pre-selected criteria parameters for optimal peripheral vision performance. | 05-14-2009 |
| 20090161065 | Methods and Apparatuses for Altering Relative Curvature of Field and Positions of Peripheral, Off-Axis Focal Positions - A method and apparatus are disclosed for controlling optical aberrations to alter relative curvature of field by providing ocular apparatuses, systems and methods comprising a predetermined corrective factor to produce at least one substantially corrective stimulus for repositioning peripheral, off-axis, focal points relative to the central, on-axis or axial focal point while maintaining the positioning of the central, on-axis or axial focal point on the retina. The invention will be used to provide continuous, useful clear visual images while simultaneously retarding or abating the progression of myopia or hypermetropia. | 06-25-2009 |
| 20100110371 | Method and Apparatus for Controlling Peripheral Image Position for Reducing Progression of Myopia - A method and apparatus are disclosed for controlling optical aberrations to alter relative curvature of field by providing optical devices and methods comprising the repositioning of peripheral off-axis focal points relative to the retina to produce stimulus for influencing the progression of refractive error while simultaneously controlling the position of the central focal point near to the retina to provide clear central vision and simultaneously providing zones of controlled peripheral defocus and other optical aberrations to improve peripheral vision for select directions of gaze. | 05-06-2010 |

| 20090076602 | EYE TREATMENT - The present invention relates to a method of determining the IOL refractive index for an ocular replacement material for replacing tissue in the capsular bag comprising combining a neutral (non-correcting) reference refractive index (“NRRI”) of between 1.421 and 1.450 with a refractive index correction factor (“RICF”) ascertained by reference to the refractive power required to correct the patient's refractive error. The present invention also relates to methods of treating presbyopia, myopia and hyperopia using the above method. | 03-19-2009 |

| 20100292631 | Control flow device - The present invention relates to a flow control device for phacoemulsification procedures. The flow control device is valve which limits the vacuum surge that can occur when an occlusion in the phacoemulsification aspiration line is dislodged. The flow control device comprises; a body; a chamber formed therein; at least one inlet in communication with the chamber; and at least one outlet in communication with the chamber; wherein the chamber has at least a first portion and at least a second portion that are substantially divided by a member where the member has at least one restricted flow passage, and wherein the member is adapted to adjust a flow rate through the body by adjusting a flow resistance through the body responsive to the flow rate through the restricted flow passage within the device. | 11-18-2010 |
