Introduction
The Wave Analyzer Medica 700 is a multifunctional eye diagnostic device. There are several
operation modes combined in a single platform: aberrometer, autorefractometer keratometer,
corneal topographer, tonometer, pachymeter and retro illumination.
The wavefront aberrometer uses the Shack-Hartmann principle and is used as an advanced
autorefractometer that measures both lower and higher order aberrations of the refraction of
the eye. The aberrometer principle can measure the maximum pupil size of the pupil or the
default pupil size specified in the settings.
The corneal topographer uses 24 Placido disks to measure the shape of the anterior surface
of the cornea. It shows a detailed description of the shape of the cornea that can be
presented as corneal aberrometry. The placido rings also function as a keratometer.
The Scheimpflug pachymeter analyzes the anterior chamber of the eye (thickness of the
cornea, irido corneal angles, anterior chamber analysis and kappa angle) by illuminating it
with a slit of light and a camera using the Scheimpflug technique.
The air-puff non-contact tonometer measures the intraocular pressure.
Retro illumination imaging captures the light reflected from the eye to help identify dark spots
on camera. It is designed to take images of eyes with pupils of a diameter of 2-8mm
The device is fully automated and a number of different measurements can be performed by a
single command including alignment and focusing.
This guide explains how ophthalmologists, optometrists, and other eye-care professionals can
use the Wave Analyzer Medica 700. It includes instructions on how to setup, operate and
maintain the unit.
Caution: Federal (U.S.) Law restricts this device to sale by or on the order of a
physician.

Indications for Use
The Wave Analyzer Medica 700 is a multi-function diagnostic device combining wavefront aberometer,
corneal topographer, retro-illuminator, tonometer and pachymeter, indicated for:
Measuring the refraction of the eye giving both lower and higher order aberrations
Measurement of the shape of the cornea
Retro-illumination imaging of the eye
Measuring the intraocular pressure without contacting the eye for glaucoma evaluation.
Photographing the eye and taking images of the eye to evaluate the thickness of the central
cornea.Anterior chamber imaging.
