Abstract: Methods and systems for assessing a visual field of a person are provided. Information can be presented to a person undergoing a visual field testing in a manner that utilizes the person's natural tendency to look at an object that is displayed so that it attracts the person's attention. A fixation target can be displayed on a display viewed by a user. Once it is determined that the user has viewed the fixation target and the person's eye(s) location is determined, a test target is displayed on the display in a location corresponding to a location on the user's visual field. The test target is determined to be either detected or missed based on user input acquired as the user is viewing the display.

Abstract: Methods and systems for assessing and/or treating visual disorders, such as discorder in accommodative ability and/or vergence ability, of a person are provided. Assessment and training exercises can be performed utilizing a computerized system in communication with a head-mountable display (HMD), such as a virtual or augmented reality display, which can display visual targets at various vergence and accommodative demands. Lenses, such as inverted bifocal lenses, may be used in combination with the HMD to mimic natural accommodative demand during viewing or to enable assessment and treatment of accommodation disorders. Corrective factors can be calculated and utilized for generation of visual targets to account for lens characteristics and/or interpupillary distance mismatch.

Abstract: Systems and methods for assessing vision and correcting vision problems are provided. A head-mountable virtual reality display controlled via a computing device can be worn by a user to display virtual reality images to the user. The images can be displayed as part of an interactive and engaging activity that can be used to determine a value of a certain parameter of the user's eyes. The activity can also be intended as a treatment procedure during which user's eyes are trained to perceive objects having certain properties that unassisted eyes of the user are normally not able to perceive. User input is acquired to determine user's perception of the displayed virtual reality images. The computing device can be a smartphone configured to perform the vision tests or treatment under control of a remote computing device operated by a trained clinician.

Abstract: A computer system is provided. The system includes a computing device including at least one data processor and at least one computer readable storage medium storing computer-executable instructions. The system further includes a device configured to communicate with the computing device and having a display. The at least one data processor is configured to execute the computer executable instructions to perform operations. The operations including displaying, using the at least one data processor and on the display, a first eye condition assessment or eye condition correction activity of a plurality of eye condition assessments or correction activities configured to measure one or more visual skills of a user. The operations further include receiving, by the at least one data processor, user input with respect to the first eye condition assessment or eye condition correction activity. The operations further include determining whether a target value of at least one parameter has been reached.

Abstract: A femoral caliper having one or more anatomical referencing members for placement against portions of the femur, such as the anterior cortex and posterior portion of the femoral condyles, to measure the femur for sizing of the femoral component. A reference mark positioning guide of the femoral caliper is connected to the anatomical referencing member and is capable of guiding placement of a reference mark on the femur that facilitates positioning of the femoral component. The femoral caliper includes an adjustment mechanism capable of displacing the reference mark positioning guide relative to the anatomical referencing member. This allows adjustment of the position of the reference mark (and hence the femoral component) on the femur to account for the up or down sizing of the femoral component. Preferably, the adjustment mechanism adjusts the reference mark positioning guide in the anterior-posterior direction to allow balancing of the tightness or laxity of the selected component.

Abstract: An illuminated masonry block that includes a hollow open-topped substantially parallelepiped-shaped housing, a substantially rectangular-shaped translucent lid, and a light source. The hollow open-topped substantially parallelepiped-shaped housing has a bottom with an outer surface and an inner surface. A pair of short sides extend upwardly from the bottom and each of which have an outer surface with a lower portion, an inner surface, and a top surface with a centrally disposed aperture. A pair of long sides extend upwardly from the bottom and each of which have an outer surface and an inner surface. The bottom, the pair of short sides, and the pair of long sides of the hollow open-topped substantially parallelepiped-shaped housing define an internal chamber with an open top.
