摘要： The intrastromal corneal ring is adjustable in thickness and has an elongated, flexible, preferably transparent or translucent body which forms a circle. The intrastromal corneal ring is of a size such that it can be inserted into a human eye and is comprised of a material which is compatible with human ocular tissue. The thickness of the ring can be adjusted so that it is not necessary to stock a plurality of different rings of different sizes to be used in connection with a method of adjusting the shape of the cornea of the eye. A plurality of different embodiments of intrastromal corneal rings, including a spiral shaped intrastromal corneal ring, are disclosed each of which are adjustable in terms of their thickness. The thickness may be adjusted prior to the insertion of the intrastromal corneal ring into the cornea and may not be further adjustable after insertion. However, in accordance with preferred embodiments the intrastromal corneal ring is inserted at a thickness which is believed to be proper and may thereafter be further adjusted in order to precisely define the desired thickness and thereby more precisely adjust the shape of the cornea and focus the light entering the eye on the retina.

摘要： A method for refractive correction of the eye in order to improve the vision of the eye while not adversely affecting its natural asphericity is described. The method involves determining the amount of correction necessary, selecting an intrastromal corneal ring (ICR) of appropriate thickness to obtain the necessary correction from a selection of ICRs of varying thickness, and inserting the ICR into the corneal stroma. The method may be useful for the correction of mypoia and excessive astigmatism.

摘要： A mask configured to be implanted in a cornea of a patient to increase the depth of focus of the patient includes an anterior surface, a posterior surface, and a plurality of holes. The anterior surface is configured to reside adjacent a first corneal layer. The posterior surface is configured to reside adjacent a second corneal layer. The plurality of holes extends at least partially between the anterior surface and the posterior surface. The holes of the plurality of holes are configured to substantially eliminate visible diffraction patterns.
