Zeiss' Humphrey Systems Partners with MicroMed to Provide Information Solutions for Eye Care Practices — MicroMed's NextGen(R) to Integrate With Humphrey's New Ensemble(R) Product

HORSHAM, Pa., Apr 30, 2001 (BUSINESS WIRE) — MicroMed Healthcare Information Systems Inc., a division of Quality Systems Inc. (Nasdaq:QSII), announced an alliance with Zeiss Humphrey Systems today at the American Society of Cataract and Refractive Surgeons (ASCRS) meeting in San Diego.

Under the agreement, Zeiss Humphrey and MicroMed will integrate Zeiss' Ensemble product with NextGen EPM and NextGen EMR, MicroMed's practice management and electronic medical records systems. In addition to other specialty, multi-specialty and primary care practices, NextGen is currently installed in the offices of hundreds of eye care professionals.

Ensemble(R) is designed to enable more efficient clinical analysis and decision-making and to facilitate a more comprehensive ophthalmic diagnosis and treatment plan. Ensemble aggregates diagnostic data from multiple instruments such as the Humphrey(R) Field Analyzer and ATLAS(TM) Corneal Topographer into one database. The software suite then provides full analysis protocol processing and unique data presentations, allowing eye care professionals to better track disease progression and treatment over time.

MicroMed will offer the integrated products through its national sales force, and Zeiss Humphrey will contribute marketing support. Attractive pricing for the integrated solution may also be provided when it is purchased in conjunction with certain Zeiss Humphrey products.
