International Classification:

A61N 1/30
A61K 38/48

US Classification:

424 9463

Abstract:

The present invention is directed to a method to prevent or reduce postoperative corneal subepithelial haze after excimer laser photorefractive keratectomy (PRK), laser in situ keratomileusis (LASIK) surgery. According to the method, a therapeutically effective amount of one or more plasminogen activators, most preferably urokinase (uPA), is administered topically to the surface of the affected eye at levels between 0. 1 and 2,500 IU/ml, about eight to twelve times on the day of surgery, and four to eight times per day for about the next six to twelve days thereafter. The most preferred therapeutic amount is from about 0. 1–1 IU uPA/ml, and also 1–10 IU/ml. Plasminogen activators that can be used in the inventions include urokinase, prourokinase, streptokinase and mutants thereof. The invention also covers topical ophthalmic compositions that include one or more plasminogen activators, most preferably uPA, to prevent or reduce postoperative corneal subepithelial haze.

International Classification:

A61B 3/00
A61B 3/10

US Classification:

351246, 351221

Abstract:

A light source is situated on a headgear device and placed to direct light toward the pupil of the eye at an intensity that causes the iris to constrict, resulting in a smaller pupil. This prevents the light scattering due to ophthalmic surgery or eye injury from entering the eye, thereby reducing or eliminating visual aberrations.

US Classification:

709229, 709245

Abstract:

Embodiments of the invention provide systems and methods for validating ownership of a domain name. According to one embodiment, a validating ownership of a domain name can comprise retrieving one or more domain name ownership records. For example, the one or more domain name ownership records comprise Who Is records. Validity of the one or more domain name records can be confirmed with a designated domain manager. According to one embodiment, confirming validity of the one or more domain name records with the designated domain manager can comprise authenticating the designated domain manager based on a certificate provided by the designated domain manager.

International Classification:

F17C 112

US Classification:

220445

Abstract:

A single-stage cryogenic tank support system is disclosed having a large-radius support tube surrounding an internal storage tank, both of which are enclosed by an external shell. The attachment tube is secured to the internal storage tank and external shell by cold and hot support rings, respectively, in a manner that inhibits thermal conductivity, provides low bending stress to the system, and avoids resonant vibrations of the system at low frequencies.
