Autonomous Technologies Receives
Favorable FDA Panel Recommendation for
LADARVisionx Laser Surgery System

ORLANDO, Florida (February 17, 1998) - Autonomous Technologies Corporation (NASDAQ NM: ATCI) today announced that the Ophthalmic Devices Advisory Panel of the U.S. Food and Drug Administration (FDA) voted unanimously, last Friday afternoon, to recommend approval of the company's LADARVisionx System for excimer laser vision correction.

The recommendation for approval is for myopia with astigmatism up to -8.00 Diopters spherical equivalent including up to -4.00 Diopters of cylinder, although -10.00 and -6.00 were sought respectively. The cylinder range is equal to the highest degree approved to date and the total range of spherical equivalent addresses approximately 95% of the myopia market.

The multicenter (six sites in the U.S.) clinical trial data for the recommended range is as follows:

Vector analysis showed 96% of the pre-operative astigmatic cylinder was corrected at 6 months while refractive stability was achieved for both spherical and astigmatic patients by 3 months.

Commenting on the Panel's announcement, Randy Frey, President and CEO of Autonomous Technologies, stated,

"We are delighted that the FDA Ophthalmic Panel has recommended the LADARVisionx System for approval. Our clinical trials team delivered greater than 95% accountability, which I believe helped the panel feel comfortable with their recommendation."

The FDA Ophthalmic Advisory Panel reviews a PMA application for approvability. The FDA accepts the advice of the Panel, but is not necessarily bound by its decision.

The company's LADARVisionx system (formerly known as T-PRK, tracker-assisted photorefractive keratectomy) is a fully integrated, user-friendly and compact laser surgery system for use by ophthalmologists on an outpatient basis to improve visual quality and clinical outcomes for low to moderate myopia. This high speed, laser radar eye tracking system utilizes a precisely controlled narrow beam shaping technology to form its new and proprietary technology platform. This sophisticated system was designed to track and compensate for the extremely rapid involuntary and random eye movements that occur during surgery and hinder conventional LVC predictability and quality. LADARVisionx provides high accuracy ablation by virtually eliminating the errors resulting from this movement. Additionally, the narrow beam excimer provides for smooth ablation at high speeds, less than 10 seconds per diopter, minimizing surgical duration while retaining the high pointing accuracy required for predictable shaping.
