Abstract: The present invention is directed to new and improved packaging systems for storing ophthalmic devices such as contact lenses and to methods for packaging such ophthalmic devices with solutions to improve the comfort of the lenses during wear. In particular, the present invention is directed to a packaging system for storing an ophthalmic device in an aqueous packaging solution comprising hyaluronic acid or a salt thereof. Such solutions are retained on the surface of an unused lens for extended periods of time, resulting in surface modification that persists in the eye, which may provide significant improvement in the wetting properties of fresh contact lenses used for the first time and, moreover, even several hours after lens insertion, thereby preventing dryness and improving lubricity.

Abstract: Spring teeth for a harvesting machine are each constructed of spring wire having a square cross section and being wound so as to define a coil torsion spring section terminating in a tine, with the tine having a leading flat surface, considered relative to the engagement of tine with the crop during pick-up operation, and having a trailing flat surface disposed parallel to said leading flat surface. The coil torsion spring is mounted to a tooth bar formed as a channel member such that the outer surface of the coils make a relatively large area contact with the tooth bar at location spaced approximately 180° from where the tine joins the coil torsion spring. This together with the fact that the contact area of the flat sides of the wire in the coil region is also quite large leads to a damping action that lessens stress in the tooth assembly.
