Contact LensCorrective contact lens, or corrective contacts, can provide temporary compensation for nearsightedness.Orthokeratology or Ortho-K is a non-surgical process that uses corrective contact lens, to reshape (flatten) the cornea to temporarily compensate or correct myopia (nearsightedness). You wear the special corrective contact lens that gently reshapes your eye so when you take the corrective contacts out you can see clearly for part or all of the remainder of the day. Ortho-K has been used, by some eyecare professionals for decades with mixed results. Today's new corrective contact lens designs have enables ortho-k to acheive much higher success rates than in the past. Some other names and variations of this process include CRT - Corneal Refractive Therapy, AOK - Accelerated Orthokeratology, CCC - Corneal Corrective Contacts and GVSS - Gentle Vision Shaping System among others. Children as well as adults can be treated with ortho-k since the principle of using corrective contact lens or corrective contacts to flatten the cornea works for both. Children may also benefit with a reduction in nearsightedness over time. Ortho-K and CRT both use ridig gas permeable (RGP) contact lens to reshape the cornea. CRT is approved, by the FDA, for overnight wear which allows you to wear the corrective contact lens at night and remove them n the morning for the benefit of improved vision throughout part of all of the remainder of the day. Although extended wear contacts present some additional safety concerns over daily wear contacts, it may be helpful to consider the fact that daily wear contacts are typically worn 10 to 16 hours per day, extended wear contacts are worn 24 hours per day (usually for 7day or 30 day periods) and CRT (or Ortho-K overnight) contact lens are worn for approximately 8 hours per day.
