Computer aided contact lens design and fabrication using spline surfaces
A method of computer-aided contact lens design and fabrication uses spline-based mathematical surfaces without restrictions of rotational symmetry. The spline encompasses any piecewise function with any associated constraints of smoothness or continuity. The method comprises some or all of the following steps: data acquisition, three-dimensional mathematical surface model construction, posterior surface description, ray tracing for anterior surface, and peripheral edge system (PES) design. The result is a mathematical or algorithmic description of a contact lens. Based on the more powerful mathematical representation of splines, these contact lenses can have posterior surfaces that provide a good fit to corneas having complicated shapes. This enables the design and fabrication of lenses (including soft lenses) with good optics for irregularly shaped corneas.

A system and method for repairing an area of defective tissue reduces the removal of healthy tissue at the margins of the defect. During excision of diseased or damaged tissue, the system tracks the movement and function of a tissue resection tool within a monitored surgical space. This movement is continuously recorded to create a three-dimensional set of data points representative of the excised volume of tissue. This data set is then communicated to a custom implant forming device which creates a custom implant sized to fit the void created by the excision. The system and method of the present disclosure allows a surgeon to exercise intraoperative control over the specific shape, volume and geometry of the excised area. Moreover, the surgeon may utilize a “freehand” resection method to excise only that tissue deemed to be diseased and / or damaged, because the custom-formed implant will accommodate an irregularly-shaped resection volume.

A bathroom floor panel for use in an airtight and water tight space is configured to be efficiently dried in a few hours under ambient conditions. When water drops onto the floor panel, the surface tension of the water is broken by irregular-shaped portions and the water spreads without forming waterdrops. Also, the irregular-shaped portions reduce the flow velocity of the water due to a gradient of the panel, so as to prevent the water flowing in channels to a drain from being discontinued. With this, although the drain velocity of the water is low, substantially no water remains as isolated drops. Further, even if some water remain on the irregular-shaped portions after the water flows out the channels to the drain, any amount of water remaining in the channels is evaporated in a relatively short period of time because the amount of the remaining water is very small.
