Various methods, other than the use of spectacles, have been advocated to correct ametropia. The corneal contact lens has become well known and is widely accepted. Other methods, such as scleral resection, refractive keratoplasty, and insertion of lenses into the anterior or posterior chamber, have been less successful in clinical application. A relatively new procedure is the insertion of an intracorneal lens.

The purpose of this study was to explore further, experimentally, the feasibility of correcting ametropia with an intracorneal lens. An attempt was made to determine (1) the most suitable material for such a lens, (2) the most suitable surgical technique for its placement, and (3) the change in the refraction of the eye produced by the lens.

Reporting in 1949 on experimental work with refractive keratoplasty, Barraquer Moner of Barcelona mentioned that a plastic lens inserted in the bed of a lamellar graft should correct hypermetropia, although he
