20090211586 | DISPOSABLE COVER FOR CONTACT-TYPE LENS PIECE - In one embodiment, a pliable film adapted to conform to parts of an optical examination device and provide a barrier between the eye of a patient being examined and the optical examination device. | 08-27-2009 |
20100110378 | ENABLING MEASUREMENT WITH A HANDHELD EYE IMAGING DEVICE - An apparatus and method is disclosed that enables an existing handheld eye imaging device to do direct measurement on images taken from the patient eye. In a preferred embodiment, a reticle is arranged in the handheld eye imaging device so that a reticle image is superimposed on the object image. In addition to allowing the user to make measurements, the reticle superimposed eye image can also be used to align the eye with the handheld eye imaging device, be used for registering images taken at different times, and also be used for finding previously recorded points on the images for comparison purposes. | 05-06-2010 |
20100110379 | OPTIMIZING VISION CORRECTION PROCEDURES - In one embodiment, an apparatus for optimizing vision correction procedures comprising: a narrow beam of light directed to a patient's retina; a dynamic defocus and compensation offsetting device configured to offset the defocus of a wavefront from an eye, a wavefront sensor configured to measure the local tilt of a number of subwavefronts sampled around an annular ring (the diameter of which can be dynamically changed) over the wavefront with the defocus offset; and a display device configured to display a two dimensional (2D) data points pattern in real time with each data point location representing a corresponding local tilt of the sampled subwavefronts. A proper defocus offset, not passive compensation, can reveal the predominant feature(s) of other wavefront aberration component(s), thus enabling a refractive surgeon to fine tune the vision correction procedure and minimize the remaining wavefront aberration(s) in real time. Meanwhile, by sampling the wavefront around annular rings and displaying the local tilt of the sampled subwavefronts on a monitor in the form of a 2D data points pattern, a refractive ophthalmic surgeon can easily correlate the measurement result to the two major refractive errors, namely spherical and cylinder refractive errors, including the axis of astigmatism. | 05-06-2010 |
20100118269 | SPLIT VIEW ADAPTER FOR A MICROSCOPE - This invention discloses an apparatus that is attached to the objective lens of a microscope to split its field of view into at least two. In one embodiment, a mirrored gonio lens is snapped to the objective of an ophthalmic surgical microscope to provide a view of the eye's anterior surface and a view of the eye's anterior chamber. | 05-13-2010 |
20100118270 | ADAPTOR FOR MOUNTING A GONIO LENS ONTO A HAND-HELD EYE EXAMINATION DEVICE - An apparatus and method is disclosed that provides a means for mounting a separate optical element, such as a gonio lens, to a hand-held eye imaging device. In this way, the doctor only needs to use one hand to hold the imaging apparatus while the other hand can be freed to open the patient eye lid and also maintain a safe relative distance of the gonio lens with respect to the patient's eye. The gonio lens and adaptor can each or both be made disposable and also mechanically switchable relative to each other as well as relative to the handheld eye imaging device so that different portions of the patient eye can be imaged sequentially without the need to rotate the hand held eye imaging device. | 05-13-2010 |
20100121442 | OPTICAL COUPLING GEL FOR EYE IMAGING - The invention discloses an optical coupling gel that has a set of desired features for application in eye imaging, including being approved for eye contact, optically transparent, able to maintain normal hydration of the ocular surface, flexible and capable of maintaining a distinct shape, minimal in breakdown/change during use, and easily dispensable/applicable. In one embodiment, the gel is made of Sodium Carboxy Methylcellulose (SCMC), where the amount of the cellulose determines the viscosity of the gel for its particular application. The right amount of gel is contained in an applicator for application to one or two eyes. | 05-13-2010 |
20120188506 | OPTIMIZING VISION CORRECTION PROCEDURES - In one embodiment a wavefront sensor is configured to measure real time aberration values of a wavefront returned from the eye of a patient while an image of the eye of the patient is being viewed by a surgeon during an on-going vision correction procedure and for providing an output signal indicating real time aberration values and a display, coupled to the wavefront sensor, is configured to show a dynamic display indicating the real time aberration values to the surgeon and configured to be viewed by the surgeon while also viewing the image of the eye of the patient during the on-going vision correction procedure. | 07-26-2012 |
20130265541 | OPTIMIZING VISION CORRECTION PROCEDURES - In one embodiment, a wavefront sensor is combined with a slit lamp eye examination device so that real time aberration values of an eye being examined can be viewed during a slit lamp eye examination session. | 10-10-2013 |
20140368794 | OPTIMIZING VISION CORRECTION PROCEDURES - In one embodiment, a wavefront sensor is combined with a slit lamp eye examination device so that real time aberration values of an eye being examined can be viewed during a slit lamp eye examination session. | 12-18-2014 |
