WHAT DOES THE PROCEDURE INVOLVE?

At the first appointment a full eye examination and computerized corneal topographical scan is performed. This gives us a chance to assess the general condition and health of the eyes and allows us to determine the likely effectiveness of the procedure. If required, a trial fitting will be done, this involves checking the patient in the morning and afternoon of the same day.

A series of ortho-k contact lenses, made from a highly oxygen-permeable rigid material, are then fitted to gently reshape the cornea towards a flatter shape. This reduces myopia and astigmatism whilst dramatically improving unaided eyesight. Excellent vision and comfort are normally maintained whilst wearing these ortho-k lenses.

Most of the visual changes occur rapidly in the first few days. The programme length varies from between 1 and 3 months depending on the degree of visual error. During the first 3 months the patient will have to make 4 to 6 visits to check on their progress. The lenses are worn during sleep for a minimum of 4 hours up to a maximum of 20 hours. This results in good vision for at least all waking hours. Some patients will be able to wear their lenses every second night, and the best case scenario is wearing the lenses every third night.
