The trapezoid shaped incision can be altered to a rectangular shape by reintroducing the sapphire blade into the incision and extending the proximal shoulders into the anterior chamber. This eliminates the need for a second sapphire knife for enlarging and creates a reproducible incision, which is not always possible when using a freehand technique.


(1)Immediately after each use,the blade should be thoroughly rinsed with distilled water,taking care not to touch

the blade with anything other than the fluid.

(2)With the blade exposed from the handle,it should then be submerged into a container holding an acceotable agent,such as any ammoniated cleaner,the blade should then be gently moved around in the solution for 30 seconds,being careful not to touch the blade on the sides or bottom of the container.

(3)Inspect the blade under microscope to insure cleanliness and the condition of the blade.Standard sterilization procedures are considered acceptable by the manufacturer.
