Choose the vision problem that interests you

People who are nearsighted have what is called a refractive error. This means that the light rays bend incorrectly into the eye who transmit images to the brain. In people with myopia, the eyeball is too long or the cornea has too much curvature, so the light entering the eye is not focused correctly. Light rays from images focus in front of the retina, the light-sensitive part of the eye, rather than directly on the retina, causing blurred vision.

Myopia is the most common visual problem in the world. Is becoming increasingly and throughout the world about a quarter of the adult population is nearsighted and this percentage increases from 30% in countries like Spain and 70% in Taiwan, where one each three adults is myopic.

DRL Lenses for Myopia treatment are higly effective up to -6.00 Diopters.

The main problem in children and adolescents is the progress of the condition. The major development to sow down the progresion comes from the field of orthokeratology lenses. For decades, practitioners actively fitting this modality reported anecdotal evidence that myopia appears to develop at a much slower rate in children wearing an overnight orthokeratology modality than in children wearing soft lenses or glasses. For years this clinical belief was disregarded because it was thought to be due to corneal change rather than to slowing of axial elongation. Corneal flattening alone would not yield a potentially permanent slowing of myopia progression, but recent work has proven that there is indeed a significant slowing of axial elongation in kids wearing overnight orthokeratology versus other correction methods.

The studies, from totally different parts of the world—the United States, Hong Kong, and Australia—all show fairly similar results: a reduction in the progression of myopia Pauline Cho and co-workers in 2005;Dr Hellen Swarbrick in 2010 and Dr Jeff Walline in 2009. Two investigations compared axial elongation of orthokeratology contact lens wearers to historical control groups of single vision spectacle wearers (Cho et al 2005) or soft contact lens wearers (Walline et al, 2009). For more than two years, these studies found approximately a 50 percent reduction in axial elongation. Recent data reported by Hellen Swarbrick and co-workers in 2010 showed slowed eye growth for eyes wearing orthokeratology contact lenses compared to the contralateral eyes wearing alignment fit GP contact lenses.

Orthokeratology may offer the most effective technique for myopia control, and it is well tolerated by children. Typically, comfort is not a problem; the lenses are much more comfortable with closed lids, as compared to the constant blinking associated with daytime gas-permeable lenses.

That is why the main indication for ortho-k in a myopic child aims to stop the progression of myopia. This is of high importance because as the refraction increases biggest is the possibility of developing eye diseases associated with myopia.
Making the miracle
Can you imagine waking up in the morning and not having to wear glasses or contact lenses during the day? It would free you up for a host of activities that you may otherwise avoid because your need to wear glasses or contact lenses.

Your nearsightedness improve dramatically the day after your first overnight use, with the new Ortho-K therapy. The Ortho-K procedure is achieved in a unique way, with the wearing of specially designed contact lenses. These lenses are custom designed to gently change the shape of your cornea ( the front curvature of your eye) to safely and quickly improve your vision. The best analogy for Ortho-K is "orthodontics for the eye".

This new method of vision improvement is accomplished most often over a period of days or several weeks to attain better vision. Ortho-K is safe, effective, and best of all, non-surgical and reversible.
