  • Patent number: 9125731
    Abstract: A microkeratome cutting head includes a head structure, an applanation plate, and a stromal plate. The head structure may include a blade cavity for receiving a blade and a blade opening through which the blade extends. The blade is configured for creating a corneal flap at a corneal flap thickness. The applanation plate is disposed at an elevation above the stromal plate plane. The elevation difference is approximately equal to the corneal flap thickness. An artificial anterior chamber (AAC) system is used to hold the donor eye for interfacing with the microkeratome. The AAC system includes an optional pressure valve and pressure gauge in a closed loop system for the user or surgeon to control line pressure applied to the donor eye during the procedure.

  • Patent number: 8070764
    Abstract: A microkeratome that includes a latch assembly that couples a head to a hand piece. The latch assembly allows the head to be readily detached from the hand piece and sterilized. There is no need to also sterilize the hand piece. The microkeratome also has a ring assembly that is coupled to the head and the hand piece. The ring assembly may include a fastener that can be unfastened to allow the hand piece and head to be detached from the ring, even while the ring assembly is fixed to a cornea. The hand piece includes a motor that moves the blade across the ring. The microkeratome may have an aspiration connector with a collar that limits the travel of the blade the and thickness of a resulting lamella flap. The aspiration connector can be replaced with a collar of a different diameter to produce a flap with a different thickness.
