A scissors is described which has two features of advantage for enlarging corneal or limbal incisions in cataract extraction. First, it has an unusually heavy shank with short blades, patterned after a wirecutting scissors (Figure).* This design insures easy and clean cutting of corneal or corneoscleral tissues without springing of the blades and crushing of tissues, which is frequently encountered with the longer, more slender blades of many scissors. Secondly, the blades are wide, with rounded tips, which push the iris away from the cutting edges. Buttonholing of the iris, a not infrequent complication with the more conventional, slender blades, is thereby prevented. Although the blades may appear unnecessarily heavy and cumbersome to casual inspection, it must be remembered that only the terminal 4 to 6 mm. of a blade is inserted into the eye for cutting purposes. No disadvantage therefore accrues.
The scissors come in a set of two
