Ortho-K, the Safe Way to Sleep in Contact Lenses

What is Ortho-K?

Sleeping without first removing one’s contact lenses is unhealthy. Doing so can cause infections, corneal abrasions, corneal ulcers — even a loss of vision.

The contact lenses used in orthokeratology (ortho-k) therapy are the exception. In fact, they are supposed to be slept in. That’s the whole point.

To slow down the progression of myopia (nearsightedness), eye doctors prescribe customized ortho-k lenses to children and teens. The lenses, which are inserted at night and removed in the morning, temporarily reshape the cornea. It’s the optical equivalent of the retainer or bite plate that your children might wear to bed at night to keep their teeth straight.

Our optometric team will prescribe ortho-k lenses to provide clear, unimpaired vision throughout the day. This enables your child to see clearly, swim, and play sports each day without wearing contact lenses or glasses.

Why is Ortho-K an Important Solution to Myopia?

OrthoK NYCOrtho-k is the go-to strategy for children and teens with myopia, first because their eyes have not fully developed, and second, because longer-term solutions like LASIK surgery aren’t an option at this age.

Myopia occurs when the axial length of the eyeball becomes elongated. The elongation causes light to land in front of the retina rather than directly on it. The result is that while nearby objects remain clear, farther-away objects appear blurry.

Glasses and contact lenses allow you to see clearly, but after a few months, the myopia may worsen as the eyeball continues to elongate. This requires a visit back to the eye doctor for an updated prescription for stronger glasses.

Ortho-k lenses provide a solution to this cycle of worsening myopia by slowing down or even stopping the eyeball’s growth.

More is at stake than correcting vision: People with moderate (-3.25 to -5.00 D) and high myopia (greater than -5.00 D) are prone to such vision-threatening conditions as cataracts, glaucoma, retinal detachment, and myopic macular degeneration later in life.

More than a quarter of the world’s population now has myopia, and half of all people are expected to have myopia by 2050. This is a vision epidemic that is worsening. Children whose parents have myopia, and those who spend most of the day indoors staring at smartphones, TVs, or tablets, are at higher risk.

When a Child with Ortho-K Sleeps Safely, Parents Sleep Soundly

Ortho-k utilizes rigid gas permeable lenses that allow oxygen to reach your child’s eyes so that the eyes remain healthy. Ortho-k lenses safely and effectively work while your child sleeps, temporarily providing clear vision during your child’s waking hours, and slowing the progression of myopia.

As long as your child handles the lenses according to the instructions of Dr. Zlatin and observes hygiene protocols when using them (washing hands first, using only the designated solutions to clean and rinse the lenses, etc.), ortho-k lenses can be safely used.

Dr. Zlatin will answer any questions you have about ortho-k. If you decide to proceed, Dr. Zlatin will conduct a thorough eye examination, fit your child with customized lenses, and oversee care.

Used by many of the most progressive and advanced Orthokeratology experts around the World, WAVE is the leader and pioneer in custom Ortho-K lens designs. Dr. Abraham Zlatin is New York’s leading WAVE designer, with nearly 20 years of experience specifically with custom made Ortho-K molds.

Fully Customized Ortho-K Lenses!

Using the corneal topography data and WAVE lens design tools we can create a personalized Ortho-K lens based on individual needs of each patient. The size and location of the optic zone and treatment zone can be modified to achieve optimal results. The results and success of the treatment are dependent on your doctors expertise in acquiring excellent corneal shape measurements and their ability to use that information to design the perfect Ortho-K WAVE NightLens®! That’s why most patients in New York choose Dr. Zlatin, a fellowship trained Orthokeratologist. He is also on the board of directors for the American Academy of Orthokeratology and Myopia Control.

Myopia Management

Myopia management demands precision. With the WAVE Contact Lens System you can design a well-fitting lens with a smaller optic zone to correct for myopia and restore clear vision while bending peripherallight to reduce hyperopic defocus, which is associated with eye elongation.
