Abstract
A capsulorhexis forceps is described which includes a unique removable hub and handle. The hub allows the use of the forceps as a cystotome in addition to a forceps. The hub design comprises a coaxial wire inside a cannula which provides minimal trauma when the forceps is opened and closed for repositioning during the capsulotromy. The hub is also replaceable and disposable after use. This flexibility in hub replacement allows the surgeon to use the forceps either in the initial open or closed position. The handle also may provide a constant grip force to the corneal flap independent of manual actuation force of the forceps.
