October 2000 –Tufden, Inc., trademarks, proprietary software, claims business, and its many hundreds of customers’ software licenses and service contracts were purchased by Vision Service Plan (VSP), the largest eye care insurance company in the U.S. At the time of the acquisition, prominent customers included the current president, current past president and other board members of the American Optometric Association (AOA), which represents more than 32,000 doctors of optometry across the country, as well as numerous optometric practices in various states. Tufden provided turnkey office automation computer systems that allowed doctors to efficiently maintain billing and marketing relationships with their patients.
December 1999 –Received sign-off on delivery of a fully functional business processing system to Vision Care, Inc., the second largest eye care insurance company in the U.S. This system, primarily designed and architected by Peter Kellner, managed the primary business functions of VCI. These functions included claims management, group and broker management and sales commissions as well as provider and lab payments. The final product was a three-tier solution involving both thick and thin clients running against an Oracle 8i server.
January 1996 –Created a business-to-business exchange so eye care doctors could send third party insurance claims through Tufden to the appropriate carriers. The architecture of this exchanged allowed customers to aggregate claims to different carriers based on server-based rules. At the time of the acquisition in October of 2000, more than 15,000 claims per month were being routed through Tufden’s servers to the appropriate insurance carriers.
June 1993 –Received sign-off on delivery to University of Houston’s College of Optometry on an 18- month project to extend our core doctors office product to handle the special processing required to manage a university clinic scheduling environment. Primary design and architecture by Peter Kellner included the capability to manage complex relationships necessary to pair teaching professors and students, in a complex scheduling environment. This environment included up to 40 appointments at any given time in the clinic. The solution used a fast ISAM database including two-phase commit logic.
January 1986 – First company in the eye care industry to market a multi-user, Intel-based, practice management software to medical offices. The solution, designed and architected by Peter Kellner ran on 8 bit Z80 processors using ISAM files and included two phase commit logic which had minimal underlying OS support. This product was later migrated to SCO Unix on Intel as well as HPUX and Solaris. The product received the exclusive endorsement of both the Florida Optometric Association and the Kentucky Optometric Association.
