Patent number: 11497766Abstract: Methods and compositions for treating various indications by lessening oxidative stress in a patient are provided. A pharmaceutical composition comprises between about 0.001% to about 10.0%, or more specifically between about 0.015% to about 5%, sodium iodide or catalase by weight. The iodine ion or the catalase dissociates hydrogen peroxide into water and molecular oxygen to interrupt biological events that result in negative side effects. The pharmaceutical composition further comprises in some cases a reducing agent or various carrier materials. The pharmaceutical composition is in some cases formulated for a variety of delivery methods.Type: GrantFiled: August 3, 2020Date of Patent: November 15, 2022Assignee: CXL OPHTHALMICS, LLCInventors: Roy S.

Patent number: 10575986Abstract: A first sponge device for use to manipulate and prepare the surface of the epithelium of an eye prior to application of an ophthalmic solution has a handle and a sponge head secured to the handle. The head is made of an absorbent, wicking sponge material and has a non-sharp, tissue preparation surface of predetermined shape for rubbing across the surface of the epithelium layer in order to manipulate the tissue. After the surface is prepared, a second, holding sponge is placed over the eye to act as a reservoir and to hold ophthalmic solution against the eye surface.Type: GrantFiled: May 12, 2014Date of Patent: March 3, 2020Assignee: CXL OPHTHALMICS, LLCInventors: Roy S.

Publication number: 20150088231Abstract: Systems and methods of ophthalmologic or ocular phototherapy treatment are provided herein. In some embodiments, the systems and methods of ophthalmic or ocular phototherapy treatment comprise applying a treatment light beam in a predetermined wavelength or wavelength range corresponding to gold (yellow to orange), red, or at least part of both the gold and red visible light wavelength ranges to at least a portion of an eye. The treatment light beam may be applied to an entire eye. In some embodiments, the selected treatment area is irradiated with light in the selected gold and/or red wavelength range at a predetermined dose for a selected time period as a primary treatment in order to treat various eye conditions and reduce eye pain or discomfort, or help to promote eye wound healing following injury or surgery, or as a secondary treatment to augment eye treatment using light in different phototherapy treatment ranges.Type: ApplicationFiled: March 26, 2013Publication date: March 26, 2015Applicant: CXL Ophthalmics, LLCInventors: Roy S.
