Ortho-K: Vision Correction While You Sleep
Finally, there is an alternative to glasses and daytime contact lenses without surgery
Therapeutic Ortho-K contact lens, an advanced corneal refractive therapy contact lens designed to gently reshape the cornea while you sleep.
Orthokeratology (Ortho-K) is a non-surgical procedure that involves the wearing of a series of specially designed rigid contact lenses to progressively reshape the curvature of the cornea over time. The results of the painless procedure are not permanent; thus, retainer contact lenses must be worn periodically to maintain improvements made in vision. Ortho-K is used to treat low to moderate nearsightedness and low degrees of astigmatism.
Ideal Orthokeratology Candidates
- Children and adults who are active and involved in sports
- Patients looking for an alternative to lasik surgery
- Patients who are too young for lasik surgery
- Patients who want to correct their myopia without the use of traditional daytime contacts or glasses
- Children whose parents want a chance to slow and possibly prevent the progression of their myopia
- Patients who have difficulties wearing traditional contact lenses because of dry eyes or allergies
Too young or looking for an alternative to Lasik
While surgical vision correction offers the convenience of not having to wear contact lenses or glasses, it is not for everybody:
- Like any surgery, there is no guarantee of a perfect outcome with LASIK or other vision correction procedures.
- Like any surgery, there are risks of complications from LASIK and other vision correction procedures. Possible complications include glare and halos around lights, persistent dry eyes and reduced visual acuity or contrast sensitivity.
- You must be over 18 for most surgical vision correction procedures, eliminating LASIK and related surgeries as options for younger athletes.
Ortho-K, on the other hand, is safe, non-surgical, non-invasive and reversible. In fact, Ortho-K is so safe that many eye care doctors are comfortable performing corneal refractive therapy for children as young as 8 years old. Additionally, Ortho-K is ideal for athletes who are too young for LASIK. Ortho-K can give them good, uncorrected vision for sports throughout their school years.
Because Ortho-K is reversible, when a child reaches the age of 18, they have the option of discontinuing their treatment for awhile (allowing their nearsightedness or astigmatism to return and stabilize) and then have LASIK surgery if they no longer want to wear corneal refractive therapy lenses overnight.
Controlling & Correcting Myopia (nearsightedness)
Otherwise known as nearsightedness or shortsightedness, myopia is a condition in which your near vision is clear but distant objects appear blurred to an uncorrected eye. This is due to the eyeball elongating as we grow during early adolescence. The result is a mismatch between the length of the eye and its optical power causing light entering the eye to focus in front of the retina rather than directly on it. Using iSee Ortho-k corneal refractive therapy lenses to gently reshape the cornea re-aligns the optical focal point onto the retina allowing patients with nearsighted prescriptions see clearly all day.
Myopic – Nearsightedness Prevention
In addition to Ortho-K corneal reshaping lenses providing nearly immediate results in correcting myopia, several studies also indicate that it helps prevent myopia from worsening in future. Traditionally, glasses and conventional daytime contact lenses have been prescribed to correct myopia. However, for children, and many adults, this correction does not prevent their myopia from worsening over time thus requiring stronger prescription lenses to achieve the necessary level of correction.
Benefits for Nearsighted Children
Since myopia is often diagnosed at an early age and progressively worsens until late adolescence, early Ortho-K treatment offers a proven, reasonable method to significantly alter the progression of myopia from increasing over time. This is important because, if left untreated, high levels of myopia (nearsightedness) may also create increased risks for other eye diseases such as glaucoma and detached retinas. By wearing Ortho-K (orthokeratology) lenses to gently reshape your corneas, you or your child now have an alternative to glasses or daytime contact lenses that may correct your myopia and prevent nearsightedness progression.
Ortho-K lenses are well tolerated by children because while their eyes are closed there is less lid sensation. Additionally, since they will be sleeping in their lenses they will not have to wear corrective lenses during the day. This means they can participate in a variety of activities, including sports, without worrying about glasses or contacts.
