Abstract: An ophthalmic information system for long-term management of pathological conditions, in which, upon receipt of patient identification information and examination data from an ophthalmic examination apparatus, a server of the system specifies a medical institution terminal corresponding to the patient identification information, and sends the patient identification information and the examination data received to the medical institution terminal specified. Further, upon receipt of the patient identification information and a report based on the examination data from the medical institution terminal, the server stores at least part of the report in a patient information storage area associated with the patient identification information, and sends at least part of the report to a patient terminal corresponding to the patient identification information.

Abstract: An ophthalmic apparatus capable of selectively performing a first imaging mode in which imaging of a subject's eye is performed in a first state where an attachment unit is not attached, and a second imaging mode in which imaging of the subject's eye is performed in a second state where the attachment unit is attached. The ophthalmic apparatus includes: an operation unit; an attachment state determination unit to determine whether or not the attachment unit is attached; a correspondence determination unit to determine whether or not the correspondence between the imaging mode designated by a use of the operation unit and an attachment state of the attachment unit obtained by the attachment state determination unit is appropriate; and a controller to perform control for prohibiting imaging in at least the designated imaging mode when the correspondence determination unit has determined that the correspondence is not appropriate.

Abstract: Devices, systems, and methods for treating and/or determining appropriate prescriptions for one or both eyes of a patient are particularly well-suited for addressing presbyopia, often in combination with concurrent treatments of other vision defects. High-order spherical aberration may be imposed in one or both of a patient's eyes, often as a controlled amount of negative spherical aberration extending across a pupil. A desired presbyopia-mitigating quantity of high-order spherical aberration may be defined by one or more spherical Zernike coefficients, which may be combined with Zernike coefficients generated from a wavefront aberrometer. The resulting prescription can be imposed using refractive surgical techniques such as laser eye surgery, using intraocular lenses and other implanted structures, using contact lenses, using temporary or permanent corneal reshaping techniques, and/or the like.

Abstract: The present invention relates to a transparent optical article comprising at least one dye at least partially inhibiting light having a wavelength ranging from 400 to 460 nm and at least one selective optical brightener that emits light by fluorescence at a wavelength ranging from 400 to 460 nm. The optical brightener acts as a means for at least partially balancing the color imparted to the transparent optical article by the dye, thus allowing for perception of said optical article as less yellow, and even colorless to an user or an observer.

Abstract: Systems and methods for providing enhanced image quality across a wide and extended range of foci encompass vision treatment techniques and ophthalmic lenses such as contact lenses and intraocular lenses (IOLs). Exemplary IOL optics can include an aspheric refractive profile imposed on a first or second lens surface, and a diffractive profile imposed on a first or second lens surface. The aspheric refractive profile can focus light toward a far focus. The diffractive profile can include a central zone that distributes a first percentage of light toward a far focus and a second percentage of light toward an intermediate focus. The diffractive profile can also include a peripheral zone, surrounding the central zone, which distributes a third percentage of light toward the far focus and a fourth percentage of light toward the intermediate focus.

Abstract: Wavefront measurements of eyes are often taken when the pupil is in a first configuration in an evaluation context. The results can be represented by a set of basis function coefficients. Prescriptive treatments are often applied in a treatment context, which is different from the evaluation context. Hence, the patient pupil can be in a different, second configuration, during treatment. Systems and methods are provided for determining a transformed set of basis function coefficients, based on a difference between the first and second configurations, which can be used to establish the vision treatment.
