Abstract
Abstract An ophthalmic template that is used for cutting an opening in the anterior capsule of the eye. It comprises a first member that has the same shape as the opening that is to be cut. A vacuum selectively retains the first member on the anterior capsule. A conduit introduces irrigating fluid into the anterior chamber to keep it formed. A method of making an opening in the anterior capsule of the eye including the steps of placing a template on the anterior capsule in the place where the opening is to be made, retaining the template in place, and removing the portion of said anterior capsule adjacent to the template.
