Abstract
A keratotomy incision is formed in a cornea manipulating an RK knife so that its blade extends a preselected depth into a preselected point on the cornea. Sufficient force is applied by a surgeon's fingers to the knife to advance its blade in a preselected direction. Advancement of the blade is halted when resistance of the cornea against the blade exceeds a certain level. A signal representative of the resistance is produced by a strain gauge or transducer in or on the knife. The level of the resistance is indicated on a display or audibly in response to the signal.
