As soon as anybleeding stops the patient looks down, the sur-geon again fixes the globe, the cystotome is intro-duced and crucial scratches are gently and care-fully but firmly made through the anterior lenscapsule on the cataract surface. 3IIC COMMONER DISEASES 01 T11K EYE The fourtli step. After the cystotomy the lenswill probably present in the wound, and itscomplete delivery may be accomplished (thepatient looking down) by gently pressing, mid-wax between the center and the lower edge of thecornea, with the rubber or metal spoon usuallyattached to the other end of the cystotome Cataract Extraction.
