Summary for Patent: 6,218,428
Title: Ophthalmic composition
Abstract:The current invention is an ophthalmic composition that combines multiple agents necessary to perform a routine eye examination. Preferably, the composition is a mixture of a topical local anesthetic, a pupillary dilating agent, and a dye, all in solution. The composition may also include a preservative, a wetting agent, a diluting agent, and/or a buffer. The preferred composition provides a means to: 1) anesthetize the cornea to allow for pain relief, manipulation and the measurement of intraocular pressure, 2) dye the cornea and conjunctiva to allow for the detection of pathology and for the measurement of intraocular pressure, and 3) dilate the pupil to allow for examination of the optic nerve, macula, retina, retinal vasculature, and peripheral fundus. In addition, the invention includes a method of using the inventive composition and a method of using currently available compositions that allow for a more rapid eye examination by eliminating or reducing a waiting period that follows the administration of dilating agents according to the present state of the art. Moreover, the inventive composition may be used pre-operatively before ophthalmic surgery, thereby conferring many of the same advantages as described above.
