METHOD AND APPARATUS FOR FACILITATING REMOVAL OF A CORNEAL GRAFT |
摘要 |
An artificial chamber that can support and pressurize a donor cornea to extract a corneal graft. The artificial chamber has a stationary stem that is adapted to support a cornea. The stem has an inner channel that allows air to pressurize the cornea. The artificial chamber has an outer cap that can be moved in a downward direction to secure the cornea. The cap has an opening that exposes a portion of the cornea to allow for the extraction of a corneal graft. The outer cap is attached to an outer sleeve that is moved by rotation of a cam. The chamber includes a spring that exerts a clamping force onto the cornea. The clamping force can be adjusted by rotating an adjustment wheel. The adjustable spring force allows an operator to set a desired clamping force that is then repeated for each grafting procedure.
