Abstract
An improved microkeratome includes a guide ring assembly for placement on the ocular globe and means for temporarily fixing the guide ring to the ocular globe. A cutting head contains an improved cutting blade having an arcuate cutting edge suitable for corneal resections. A vertical support assembly is connected to the guide ring and supports the cutting head for rotation about a horizontal axis such that rotation of the cutting head about the horizontal axis moves the cutting blade along an arcuate cutting path into engagement with the cornea of the ocular globe, whereby the arcuate cutting edge of the cutting blade cuts a substantially rounded corneal disk. An improved method related to the use of the arcuate cutting blade is also provided.
