Probably ALL ophthalmic surgeons have thought of the use of strong convex lenses to assist in operating. To those who have reached that stage of maturity that brings presbyopia, something of the kind is a necessity; and for those who have not, the possible advantages to be gained by working with magnified images may have occupied time spent in waiting for practice.

The first attempt in this direction is made by putting a pair of strong convex lenses in a trial-frame. But such an arrangement, even with lenses permanently mounted in spectacle frames, has proven unsatisfactory. It shuts off distinct vision, except by looking around the glasses, does not give sufficient magnification, and brings the surgeon's eyes too close to the eye he is operating on.

See Commentary on page 868

Another method has been to employ a strong magnifying lens, held close to the eye to be operated on.
