ABSTRACT:
A lense for keratometry and a keratotome for making an incision for receiving such a lense. The lense comprises an optical zone and an anchoring zone with a sloping shape such that this zone can be inserted under a strip disengaged from the cornea of the receiving eyeball via a tapering incision diverging from the cornea. The keratotome according to the invention is adapted to perform such an incision. The result is that the lense is anchored in the cornea in a more efficient, less traumatic and more aesthetic manner.
