  • Publication number: 20140296890
    Abstract: An iris scraping surgical method using an iris scraping tool treats secondary pigmentary glaucoma. The iris scraping tool is inserted through an incision in the sclera made with a separate surgical instrument. The iris is lifted away from the lens and pigmentary debris and cellular debris gently scraped from the backside of the iris to relieve pressure buildup caused by the debris blocking fluid flow between the iris and the lens. An iris scraping convexly curved dull edge of the iris scraping blade conforms to the underside of the lifted iris. A lens clearing concavely curved dull edge conforms to the shape of the adjacent lens surface.

  • Publication number: 20110213394
    Abstract: An iris scraping surgical method and tool to treat pigmentary glaucoma by making an incision in the sclera, lifting the iris and scraping away the pigment and debris attached to the backside of the iris thereby relieving the pressure buildup caused by the pigment blocking fluid flow between the iris and the lens and allowing the fluid to flow, and closing the sclera. The tool comprises a pointed sharp tipped double edged flat blade and handle surgical tool two opposing dull non cutting scraping blade edges extending back from the front tip, the entire aluminum handle and aluminum blade including the tip, and scraping blade edges having a durable plastic coating to withstand operating conditions and all forms of sterilization procedures.

  • Patent number: 7854741
    Abstract: An iris scraping surgical method treats pigmentary glaucoma in which the pigment attaches to the underside of the iris. An incision is made in the sclera. The iris is lifted and pigment and/or cellular debris is scraped with a scalpel from the bottom layer (pigment epithelium) of the iris. The iris lifted up from the lens to remove the build up of escaping pigment on that layer to let the fluid flow out at a normal rate to drain out of the trabecular meshwork and then the iris is lowered and the incision in the sclera is closed.

  • Publication number: 20090112240
    Abstract: An iris scraping surgical method and The Iris “T” Aluminum Scraping Scalpel Surgical Glaucoma Treatment Tool to treat pigmentary glaucoma by scraping away the pigment and debris attached to the underside of the iris thereby relieving the pressure buildup caused by the pigment blocking fluid flow between the iris and the lens. An incision is made in the sclera. The iris is lifted and pigment and/or cellular debris is scraped with The Iris “T” Aluminum Scraping Scalpel Surgical Glaucoma Treatment Tool, a double edged flat handle surgical tool from the natural bottom layer (pigment epithelium) on the underside of the iris. The fluid can then flow out at a normal rate between the iris and the lens to drain out of the trabecular meshwork to prevent pressure buildup. The iris is lowered and the incision in the sclera is closed.
