Studies have indicated that Orthokertalogy lenses may be a viable myopia treatment option to slow the progression of nearsightedness in children.Otherwise known as nearsightedness or shortsightedness, myopia is a condition in which your near vision is clear but distant objects appear blurred to an uncorrected eye. This is due to the eyeball elongating as we grow during early adolescence. The result is a mismatch between the length of the eye and its optical power causing light entering the eye to focus in front of the retina rather than directly on it.
Using iSee Ortho-k corneal reshaping lenses to gently reshape the cornea re-aligns the optical focal point onto the retina allowing patients with prescriptions as high as -10.50 to see clearly all day. Although the use iSee Ortho-k corneal refractive therapy lenses are not FDA approved for myopia progression control, there are many studies that suggest that Ortho-k therapy may reduce the progression of myopia(nearsightedness) in many children and adolescent Ortho-k therapy patients.In addition to Ortho-K corneal reshaping lenses providing nearly immediate results in correcting myopia, several studies also indicate that Ortho-K corneal refractive therapy lenses may help prevent myopia from worsening significantly in future.
Traditionally, glasses and conventional daytime contact lenses have been prescribed to correct temporarily myopia. However, for children, and many young adults, this correction does not prevent their myopia from worsening over time thus requiring stronger prescription lenses to achieve the necessary level of correction.Visit http://www.isee.com/ for more information on the advantages of ortho-k lenses.
Ortho-K is a non-surgical procedure that helps to correct nearsightedness by reshaping the cornea, which is quite popular nowadays. However, there are still both advantages and disadvantages. On the one hand, ortho-k lenses can provide good vision without surgical procedure and it is not painful and relatively less expensive than surgery. On the other hand, ortho-k treatment is time consuming, needing several visits to the eye-care doctor as well as several lens change and wearing retainer lenses will become imperative to ensure that the cornea does not revert to its original shape. Besides, the exact decrease in myopia cannot be guaranteed and the initial costs are higher compared with soft contact lenses. To sum up, you should weight the advantages and disadvantages careful by yourself.
Compared with other contact lenses, the Ortho-K lenses are so special at one point. That is its function of reshaping the shape of corneal. Through doing this can this type of special contact lenses help the nearsighted people see clearly and help them correct the short sighted symptom to some degree. In a word, the amazing reshaping function can be called the most powerful advantage of Ortho-K lenses.
