SF Bay-Area Optometrist Announces a New Clinical Trial of a Novel Contact Lens for Treating Hyperopia in Children

(PRWEB) March 18, 2015

Internationally known optometrist and vision researcher Dr. Thomas Aller is proud to announce a new clinical trial of a contact lens for treating hyperopia in children. Dr. Aller is now recruiting 20-40 subjects, ages 5 to 12 who have moderate to high levels of hyperopia. The study will seek to establish that hyperopia can be reduced through the use of soft contact lenses with specialized optical designs.

Myopia, also known as nearsightedness, results when either the eye is too long or the power of the eye is too strong, resulting in blurred distance vision. Hyperopia, or farsightedness, on the other hand, results when the eye is too short or the eyes power is too weak, causing blurred or uncomfortable vision at near distances.

Dr. Thomas Aller has been researching the use of bifocal and multifocal contact lenses for the treatment of progressive myopia in children for over twenty years. Dr. Aller presented the results of his randomized controlled clinical trial at the recent American Academy of Optometry annual meeting in Denver, CO. The control study, currently in prep, showed that certain types of bifocal soft contact lenses reduced myopia progression and axial elongation in children and adolescents by over 80% as compared to standard single vision contact lenses.

While it is yet to be proven what precise mechanisms are behind the myopia control found with bifocal contact lenses, it is commonly argued by researchers that it relates to the reduction in blurred vision in the periphery that is typically found in people with myopia, particularly when their vision is corrected by conventional glasses or contact lenses.

As a clinician, scientist and inventor, I just think it would be very cool to prove that the same contact lens, prescribed a bit differently, could either cause a myopic eye to slow its excessive growth or could encourage a shorter, hyperopic eye to grow to a more normal size, says Dr. Aller.

In over twenty cases of adults trying such lenses, Dr. Aller found little to no effect.

This may have to do with the fact that adults with hyperopia have very stable prescriptions and very stable eye length, says Dr. Aller. There have, however, been some intriguing results with children, enough so to prompt this new clinical trial.
