Imagine waking up in the morning and being able to see your alarm clock, drive to work, exercise, and go about your entire day — all without reaching for glasses or inserting contacts. That's exactly what orthokeratology, or Ortho-K, delivers for the right patients. It's one of the most exciting options we offer at Harnos Optometry in New Paltz, NY, and it continues to change lives for patients who've worn glasses for decades.
How Ortho-K Works
Orthokeratology uses specially designed rigid gas-permeable contact lenses that you wear only while you sleep. Over the course of 6–8 hours, the lenses gently and precisely reshape the front surface of your cornea — flattening the central curvature in a controlled, predictable way. When you remove the lenses in the morning, your cornea retains that new shape throughout the day, bending light correctly onto your retina and producing clear, unaided vision.
The effect is temporary and fully reversible. If you stop wearing the lenses, your cornea gradually returns to its original shape over a few days. There's no surgery, no permanent alteration, and no commitment — you simply wear the lenses each night to maintain clear daytime vision.
Who Benefits Most from Ortho-K?
Ortho-K is FDA-approved and has an excellent safety record since 2002. It's most effective for patients with mild to moderate myopia (nearsightedness) and mild astigmatism. It's particularly popular with:
- ◆Athletes and active adults — swimmers, contact sports players, cyclists, and outdoor enthusiasts who find glasses and contacts inconvenient or impractical
- ◆Children with progressing myopia — Ortho-K is one of the most clinically proven methods for slowing myopia progression, with studies showing 30–60% reduction in progression rates. For a child whose prescription is increasing every year, this can make a meaningful difference in their long-term eye health
- ◆LASIK candidates who aren't ready — Ortho-K provides a reversible, surgery-free alternative for patients who want freedom from glasses but aren't ready to commit to laser correction
- ◆Dry eye patients — because lenses are worn only during sleep with eyes closed, many patients who can't tolerate daytime contact lens wear do extremely well with Ortho-K
What the Process Looks Like at Harnos Optometry
We begin with a comprehensive consultation and corneal topography — a painless, non-contact 3D mapping of your corneal surface. Using this map, we select or custom-order lenses designed precisely for your corneal shape and prescription. Most patients notice meaningful improvement in their uncorrected vision after the very first night, with full effect typically achieved within one to two weeks.
