Keeler Symphony Zeiss Z-Style Slit Lamps – Exceeding performance expectations

The Keeler Slit Lamp facilitates an examination of the anterior segment, or frontal structures and posterior segment, of the human eye, which includes the eyelid, sclera, conjunctiva, iris, natural crystalline lens and cornea.

The binocular Keeler Symphony Zeiss Z-Style Slit Lamps provide stereoscopic magnified view of the eye structures in detail, enabling anatomical diagnoses to be made for a variety of eye conditions.

The KSL Digital Slit Lamps come with many additional features outside the scope of the traditional Slit Lamp. As well as benefiting from a selection of integrated cameras and beam splitters (optional for the Digital Ready version), additional features include a background illuminator, auxiliary diffuser, blue filter, and control buttons on the Slit Lamp base for the camera and review control.

Manage the camera exposure and Slit Lamp illumination from the base mounted buttons, and capture the perfect image using the joystick camera trigger for still images or videos, depending on the software package purchased.

External illumination can be controlled independently of the main illumination to ensure image contrast levels are optimised.

The Z series Keeler Slit Lamps share all the great qualities and features of the K series but with lower illumination.
