Abstract
The present invention relates to apparatus for radial ketatotomy. A support (1), having a reference surface (3) adapted to fit the cornea (2a) of an eye (2) and in which opens slits (19) disposed in planes including an axis (4) adapted to coincide with the optical axis (105), carries blades (22) of which each is associated with a respective slit (19), and means for simultaneously moving the assembly of blades (22) for a movement in the associated slits (19) towards or away from the axis (4); the blades (22), projecting with respect to the reference surface (3), then simultaneously cut the cornea (2a), advantageously pressed pneumatically against the reference surface (3). The simultaneous making of all the incisions is rapid, and the blades work in identical conditions so the incisions have reproducible geometric characteristics and the risks of perforation of the cornea are reduced.
