Dimensional Stability Of The Ultracon Contact Lens.

The new non-toric UltraCon contact lens may be the most significant breakthrough in contact lens technology in over twenty years. It offers an alternative to better and easier fitting of astigmatic patients with the characteristics of both RGP' s and hydrogel contact lenses. UltraCon is a non-water based, flexible, high Dk lens soon to be introduced in Canada and will be available in the U.S.A. by 1995, pending FDA approval. This lens has been the product of five years of joint research and development by Specialty Contact Lens of Calgary, Alberta, Rasor Associates of Sunnyvale, California and the University of Alabama, College of Optometry and has yielded a remarkable new contact lens material. This study is part of the continuing clinical trials to test the dimensional stability of the UltraCon lens in a variety of commercial contact lens solutions.
