Abstract
In a corneal surgical apparatus for incising a cornea of a patient's eye in a layered form, a blade is movably supported to a main body for lateral oscillation and rectilinear movement. Discrete motors are located within the main body for the lateral oscillation and the rectilinear movement of the blade, respectively. One of the motor is coupled to the blade through a feed screw, an attaching member threadingly engaged with the feed screw, and a hollow connecting member connected to the attaching member, whereas the other of the motor is coupled to the blade through gears, a spline shaft rotatably supported by the inside of the hollow connecting member and non-rotatably but slidably connected to one of the gears, and a converting mechanism for converting the rotation of the shaft to the lateral oscillation of the blade.
