Evaluation of the effects of circular Descemet's membrane incision on the biomechanical, topographic and optical properties of rabbit corneas.

Background:   Prospective interventional animal case series to investigate quantitatively changes in corneal light-scattering, corneal hysteresis, keratometry and pachymetry induced by circular Descemet's membrane incision.

Methods:   Thirty mature New Zealand White rabbits were divided into three study groups: (i) surgical intervention with circular Descemet's incision; (ii) surgical control; and (iii) medical control. Group 1 eyes had two paracenteses placed 120 degrees apart and an 8.
