Clinical and ultrastructural analysis of variable speed corneal trephination.
An automated, variable speed trephine was utilized to study the effects of rotation velocity on corneal trephination. Scanning electron microscopy revealed that the higher velocity (800 RPM) specimens had less stromal lamellar disruption, producing a smoother interface than either the lower velocity (100 RPM) automated trephinations or manual trephinations.
