Iris scissors are designed for eye surgery and not for skin surgery and hence the name. Iris scissors are used for remove necrotic tissue. These are very sharp, pointed scissors, available with either curved or angular cutting blades. Straight scissors are for flat surfaces. They are fine, curved scissors that follow the contours of tissue in a small area. They are rather handy multipurpose scissors for cutting dressings, gauze, tape, and curved ones are especially good for cutting duoderm and ostomy wafers. They are considered to be good starting scissors for beginners in dissection. Besides being used as operating scissors, iris scissors are very useful for fine cutting in embroidery as well.
