WAM 800

Overview

WAM 800 is a fully automatic anterior segment screening instrument for optometrists and eye care practices. In a single sequence of about two minutes it can perform up to nine types of measurement: objective refraction, aberrometry, corneal topography, keratometry, non-contact tonometry, pachymetry, retro-illumination, pupillometry and monocular accommodation assessment. It replaces several separate pre-test stations, so practices gather the key data on every patient quickly and consistently, then spend chair time on the conversation that matters. WAM 800 is the current successor to the WAM 700+.

Comprehensive anterior segment screening

• Intraocular pressure: non-contact tonometry with a fixation point, measured as one of the risk factors for glaucoma.
• Anterior chamber analysis: Scheimpflug imaging gives pachymetry and a precise measurement of iridocorneal angles.
• Keratoconus screening: Placido ring topography analyses more than 100,000 corneal points and gives a keratoconus probability index.
• Contact lens data: a 3D simulation of corneal curvature, combined with pupillometry, supports contact lens fitting.
• Cataract screening: infrared retro-illumination gives a detailed view of crystalline lens opacity.

Objective vision evaluation

Pupil behaviour and ocular aberrations are key reasons why vision quality drops in changing light. Using Shack-Hartmann wavefront technology, WAM 800 measures objective refraction and pupil size in photopic and mesopic conditions and at near.

• Day and night vision simulation based on the point spread function shows patients how they see.
• Monocular accommodation assessment evaluates objective refraction in real time while the patient focuses on near objects.
• Accommodative effort is displayed automatically by reading distance in centimetres, useful when discussing visual fatigue and presbyopia.

Efficiency and patient engagement

An intuitive interface on a 10.1-inch multitouch screen gives quick access to predefined protocols, so trained staff can run the screening and the practitioner reviews the results. Detailed reports set out each patient’s objective vision performance in clear graphics. These support patient education on presbyopia, visual fatigue and day and night vision, and help explain why a particular lens solution is recommended. WAM 800 connects to the practice network through LAN, USB, RS232 and VGA outputs and includes an integrated printer.
