A corneal punch: feasibility and accuracy.
Abstract
A corneal punch used for making circular holes in the aorta was tried on pig eyes to check for efficacy and accuracy. This approach was rejected as being clinically useless because the incision necessary to introduce the punch was larger than the diameter of the cut, intraocular trauma was felt to be inevitable due to the large amount of effort necessary to punch, the tissue removed was oval and the internal diameter was much larger than the external diameter of the tissue cut.
