Advantages of wearing Menicon Alpha Ortho K lens

Since the corneal reshaping impact is impermanent, little danger is included, and you can stop wearing the lenses at any time — provided you are eager to start wearing glasses or contacts again when your myopia returns!

Children and young adults who want to be glasses-free but are too young for LASIK or are not good candidates for refractive surgery due to reason such as dry eyes often are good candidates for ortho-k. People who participate in contact sports or work in dusty environments that can pose problems for contact lens wear also can be good candidates.

Lens structure

Menicon Alpha Ortho K

The base curve (BC) is the part that presses the anterior surface of the cornea to flatten it in accordance with the target power of the patient compression of the cornea by the base curve is responsible for this effect. The alignment curve (AC) is responsible for centering the lens and achieves a competent refractive effect. The reverse curve (RC) is the part responsible for reshaping the comeal epithelial cell layer. The peripheral curve (PC) encourages tear exchange and smooth removal of the lens.

When the Alpha ortho k fit is finished, the next night the wearer should sleep while wearing the lens, and have a consultation on the next morning following the first night of lens wear.

Fitting assessment

When the lens fitting evaluation has been finished, the lens ought to be taken out for corneal topography to be performed to survey corneal changes. Despite the fact that the corneal topography on the early morning following the first night of over night wear will give important data about the lens fit, the outcomes from the following three weeks of lens wear is crucial too as it will direct whether the lens fit is satisfactory.
