Night lenses

Monday, 1 June 2020

You have decided to try Corneal Refractive Therapy! The use of night lenses is a new method, which basically stops the development of myopia and prevents the development of the accommodation spasm.

Night lenses are special therapeutic lenses, which gently and temporarily, by soft gliding, change the curvature of the corneal surface during sleep. The effect achieved by refractive therapy, with the help of night lenses, is similar to the result of laser correction. The use of night lenses allows short-sighted people to see well without glasses and contact lenses. Night lenses are indicated for the correction of myopia up to -6.5D with astigmatism not more than -1.75D.

Night lenses have two different surfaces depending on their action. The external-optical-active surface refracts light and offers the possibility to have 100% visual acuity with them. The internal surface is of a compound structure and actively acts on the corneal epithelium, forcing it to gradually migrate from the center to the periphery. Thus, the refractive power of the cornea changes to the exact required size. When the patient removes the night lens, the effect is maintained for another 48 hours, the image is formed on the retina and the patient sees well.

Night lenses are made of a special material that is permeable to oxygen and this permeability reaches 100%.

The lenses should be applied at night, 5-10 minutes before bedtime. Oculus Prim Medical Center recommends the night lenses, and once chosen correctly, they ensure full comfort with your eyes closed.

The final stable effect (100% vision during 24 hours) will be achieved in about 4-7 days (depending on the degree of myopia). The average time to wear the night lenses is 6-8 hours.

Caring for night lenses is simple. They should be mechanically washed using a contact lens solution after each wear and stored in a special lenses container.
