## Device Story

EyeSys Vista is a non-invasive corneal topography system; measures and records corneal curvature. Operated by doctors and technicians in ophthalmic/optometric offices. Provides corneal topography maps for patient screening, surgical planning, and contact lens fitting. Output used by clinicians to document corneal health and guide clinical decision-making for refractive surgery and contact lens management.

## Clinical Evidence

No clinical data provided; substantial equivalence based on technological and intended use comparison to existing topography systems.

## Technological Characteristics

Non-invasive corneal topography system; measures corneal curvature. Designed for use in ophthalmic and optometric clinical environments. Technical specifications and materials not detailed in provided documentation.

## Regulatory Identification

A keratoscope is an AC-powered or battery-powered device intended to measure and evaluate the corneal curvature of the eye. Lines and circles within the keratoscope are used to observe the corneal reflex. This generic type of device includes the photokeratoscope which records corneal curvature by taking photographs of the cornea.
