Wave Analyzer Medica 700 User Guide

1. Introduction

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.

1. 1 Indications for Use

Keratoconus Table

The Keratoconus table displays the following data:

KPI: Index of the probability of keratoconus

CAUTION: Keratoconus indices are designed to be an adjunct to a clinical examination, and should never be used as a sole assessment tool in the diagnosis of Keratoconus.

Results of a clinical trial of the Keratoconus Prediction Index (KPI) are described in reference 1 and more details of the mathematics are given in reference 2.

Eccentricity Table

The Eccentricity table shows the eccentricity of the cornea (P, e, or q as selected in the settings menu) at various predefined positions. The positions are defined by the meridian and by the angle from the keratometric measurement axis. R0 is the apical position (corneal apex) and the angles are 10º, 15º, 20º, 25 º, and 30º. The meridians used are the nasal, temporal, inferior, and superior semi-meridians and the horizontal and vertical meridians. The mean is the average of the horizontal and vertical meridians.

Sagittal Radius Table

The Sagittal Radius table shows the radius of the curvature of the cornea at various predefined positions. The positions are defined by the meridian and by the angle from the keratometric measurement axis. R0 is the apical position (corneal apex) and the angles are 10º, 15º, 20º, 25 º, and 30º. The meridians used are the nasal, temporal, inferior, and superior semi-meridians and the horizontal and vertical meridians. The mean is the average of the horizontal and vertical meridians.

4. 9 Coeff. Aberr.

The Aberration Coefficients tab shows the values of the Zernike coefficients in units of mm for:

Ocular Corneal Internal

There are three options for the aberration coefficients to be displayed:

Main Values: Shows a selection of the most common aberrations; defocus, astigmatism, total lower order (LOA), total higher order (HOA), coma, spherical aberration, fourth order astigmatism, trefoil and tetrafoil. Aberrations are shown in value and axis form.

Wave Analyzer Medica 700 User Guide

Overview of the Software

LOA: Shows the values of the lower order aberrations, total LOA, tilt, defocus and astigmatism.

HOA: Shows the values of the common higher order aberrations, total HOA, trefoil, coma,

tetrafoil, fourth order astigmatism, spherical aberration, pentafoil, fifth order trefoil and fifth order coma.

The Optical Path Difference (OPD) is defined as the difference between the aberrated and the ideal unaberrated wavefronts. The OPD is positive if the aberrated wavefront leads the ideal unaberrated wavefront. Also, if the aberrated wavefront curves in more than the unaberrated wavefront, the OPD is positive. Therefore, a negative focal shift will introduce a positive aberration.

OPD and WFE modes relate in the following way:

OPD(x,y)= -WFE(x,y)

The chosen mode is marked on the left side of the coefficient chart above the table.
