To the Editor.
—In the August 1988 issue of the Archives, Rostron et al1 reported successful experimental epikeratophakia in rabbits with the use of a biological adhesive, eliminating the need for any suturing.My colleagues and I2 have been able to obtain similar results with synthetic epikeratophakia in monkeys, using type IV collagen lenses of human placental origin. A larger disparity between the diameter of the collagen lenticule (7 mm) and the diameter of the trephination (4 mm) permitted successful epikeratophakia without suture and without adhesive.
