What is Orthokeratology?


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. Ortho-K lenses are custom designed nightwear lenses that are made according to one's corneal shape. A special diagnostic technology called a corneal topographer is utilized to "map" out the exact shape of the front part of the eye called the cornea. Using the data from the mapping of the cornea, the Ortho-K lenses will be made to a person's personal prescription, and  in accordance with the shape of the cornea.


This is a revolutionary non-surgical procedure that eliminates the need for glasses or daytime contact lenses. It improves vision by gently reshaping your eye WHILE YOU SLEEP using specially designed therapeutic contact lenses. You just put the specially fitted lenses in at bedtime, and when you awake, you will have clear, sharp, natural vision for your waking hours. 

The results of the painless procedure are not permanent; thus, retainer contact lenses must be worn periodically to maintain improvements made in vision. This safe and effective treatment can correct low to moderate nearsightedness and low degrees of astigmatism. It is a great alternative to LASIK for those who don’t want the risk or are not ready for surgery. 


How Do Ortho-K Lenses Work?

Ortho-k lenses are not your typical contact lenses. They are made from a special gas-permeable material. This allows them to breathe and provide comfort during sleep. These lenses work by gently flattening the cornea. This changes how light enters the eye, improving vision. The result is clear vision during the day. This is achieved without the need for glasses or daytime contact lenses.

Is Ortho-K Safe?

Orthokeratology is generally considered safe. However, like any procedure, it comes with potential risks. These include minor side effects like halos or glare. The key to safety is proper lens care. This includes maintaining good hygiene practices to prevent infections. Regular follow-ups with an eye care professional are also crucial. They ensure the correct fit of ortho-k lenses and monitor eye health.

Who Can Benefit from Ortho-K?

Orthokeratology is primarily used to correct myopia, hyperopia, and astigmatism. It's a great alternative for those who are not candidates for LASIK surgery or are hesitant about it. Ortho-K is also beneficial for athletes and active individuals. The convenience of being free from corrective eyewear during the day is a significant advantage. Moreover, individuals who experience discomfort with daytime contact lenses due to dry eyes or allergies may find relief with ortho-k.


Age Considerations for Ortho-K

The ideal age for ortho-k can vary. However, it is commonly used for children and teenagers whose eyes are still developing. Ortho-k can slow the progression of myopia in children. This makes it a valuable tool in managing this increasingly common condition.

Orthokeratology offers a safe and effective alternative to glasses or daytime contact lenses. Remember, regular follow-ups are essential to monitor eye health and ensure the correct fit of ortho-k lenses.We provide orthokeratology services to various parts of the San Fernando Valley, including Reseda, Winnetka, Northridge, Tarzana, Woodland Hills, and Canoga Park.
