### 3.4 Device description
An AC-powered slit lamp biomicroscope is an AC-powered device that is a microscope intended for use in eye examination that projects into the patient's eye through a control diaphragm a thin, intense beam of light.
This Keeler Slit Lamp has an XYZ translation base that is either mounted onto a custom table top supplied by Keeler or can be mounted on a third parties table top (refraction unit) by suitably trained technicians.
Fitted to the XYZ base is the illumination and observation system; fitted to the table top is the chinrest assembly with fixation target.
The illumination system rotates around its mounting axis and has a number of filters and graticules allowing the user to control precisely the characteristics of the examination light. The magnification body has a magnification change systems and eyepieces adjustable for the user's individual pupillary distance and distance correction.
The patient is seated in front of the slit lamp with his/her chin in the chin rest and forehead against the forehead rest. The chin rest can be adjusted in height to align the eyes of the patient with the optics/light beam.
With the control lever the instrument can be moved back and forward until the slit appears in focus on the cornea. The image can be observed through the microscope. The base unit has a rheostat to control the illumination level.
Various magnifications can be selected on the microscope. For different observations the slit width can be changed, the slit can be tilted horizontally, and the angle between the illumination unit and the microscope can also be varied horizontally.
### 3.5 Indications for Use
The Keeler Slit Lamp is an AC-powered Slit lamp biomicroscope and is intended for use in eye examination of the anterior eye segment, from the cornea epithelium to the posterior capsule. It is used to aid in the diagnosis of diseases or trauma which affects the structural properties of the anterior eye segment
This device is intended to be used only by suitably trained and authorised healthcare professionals.
