AI Technical Summary

Technical Problem

Existing ophthalmic microscopes, particularly slit-lamp microscopes, are difficult to operate due to the lack of haptic feedback from touch-sensitive displays, making it challenging to control various functions effectively.

Method used

Incorporating a joystick with a rotatable wheel and a control unit that includes a joystick handle and a rotatable wheel below the joystick, allowing for intuitive control through rotation and click functions, along with a touch-sensitive screen that ignores unintended touches during joystick operation.

Benefits of technology

Enhances user interaction by providing haptic feedback and reducing accidental screen touches, resulting in a more intuitive and efficient operation of the microscope.

Abstract

The invention relates to an ophthalmic microscope, in particular a slit-lamp microscope, comprising a microscope unit, a control unit for controlling the microscope, and an input device for entering control commands by a user. Said input device comprises a joystick (10) with a joystick handle and a rotatable wheel (19) arranged below said joystick handle (15). Both the joystick (10) and the rotatable wheel (19) are adapted to enter control commands. The rotatable wheel 19 allows the user to select menu options or setting values in a comfortable way.
