摘要:
In one aspect, the present invention provides a method for correcting vision that employs two lenses, at least one of which is a multifocal lens, with different focusing characteristics for use in the two eyes of the patient. The visual performance of each lens (e.g., visual contrast or acuity) is selected in accordance with a predefined relation so as to optimize the binocular visual performance provided by the combination of the lenses.
摘要:
A system for top-down evacuating and rinsing of a user-mounted colostomy bag has a valve assembly affixed through one wall of the colostomy bag, the valve assembly having a first coupling interface and an interiorly protruding stem, at least one solution reservoir for containing an aqueous solution, and a second coupling interface attached directly to or indirectly to at least one of the at least one solution reservoir, the coupling interface for connecting the reservoir to the valve for communication of the aqueous solution from the reservoir to the bag.
