Orthokeratology is called by different names such as Ortho-K, Corneal Refractive Therapy, CRT, Vision Shaping Treatment, VST, Gentle Shaping System, The Gentle Vision Shaping System, Corneal Molding, Wave Front Corneal Molding, and Gentle Molding. It is a process of using specially designed GP contact lenses to temporarily reshape the contour of the cornea in order to reduce myopia (nearsightedness). This technique of Ortho-K is now a viable and it is the reversible alternative to refractive surgery. The main reason of Ortho-K is that one should be free of both contact lenses and spectacles for the majority of, or possibly all, waking hours. It is a non surgical process which reshapes the cornea of the eye by using custom designed RGP lenses.

Orthokeratology is for people of any age who are suffering from nearsightedness. Ortho-k suits best to the people particularly who participate in sports, or who work in dusty, dirty environments that can cause problems for regular contact lenses.

After a full eye examination and computerised corneal topographical scanning, then determining that the person is eligible for this procedure, a series of Ortho-K contact lenses which is made from highly oxygen permeable rigid material, are fitted in progressive stages to gently reshape the cornea towards less curvature and a more spherical shape. This will reduce myopia and astigmatism whilst dramatically thus improving unaided eyesight. Hence, excellent vision and comfort are normally maintained whilst wearing Ortho-K lenses.

Advantages of Ortho-K:

• Good vision without spectacles or contact lenses for possibly most of the day.
• It is not a surgical procedure
• It may slow down the increase in myopia in children
• Using well established contact lens fitting techniques hence there will be very few risks.
• Time consuming

After Conductive keratoplasty (CK), some of the precautions have to be taken such as, one should avoid exercising for a week to prevent the sweat from dripping into the eye, one should avoid getting soap in their eyes for at least one week after the procedure and avoid make-up for a week after the surgery and also should not rub your eyes for two weeks after surgery.
