Orthokeratology, also known as Ortho-K, is a non-surgical vision correction technique that uses specially designed rigid gas permeable (RGP) contact lenses to temporarily reshape the cornea, the clear front part of the eye. These lenses are worn overnight while you sleep, and they gently mold the cornea, reducing or eliminating common refractive errors like nearsightedness (myopia), farsightedness (hyperopia), and astigmatism.
 

The process of Ortho-K is reversible, meaning that when you stop wearing the lenses, your vision gradually returns to its original state. This makes Ortho-K a popular choice for individuals who want to reduce their dependence on glasses or daytime contact lenses, especially those with active lifestyles or who engage in sports.
 

Understanding Astigmatism

Astigmatism is a common refractive error that occurs when the cornea or the lens inside the eye is irregularly shaped, causing light to focus improperly on the retina. This results in blurred or distorted vision at all distances. Astigmatism can be present alongside other refractive errors, such as myopia or hyperopia, further complicating vision issues.
 

The degree of astigmatism can vary greatly, from mild to severe. Mild astigmatism may only cause slight blurriness, while more significant astigmatism can lead to eye strain, headaches, and difficulty with tasks like reading or driving. Correcting astigmatism is essential for achieving clear, comfortable vision.
 

How Does Ortho-K Correct Astigmatism?

Ortho-K lenses are designed to temporarily reshape the cornea, including the areas affected by astigmatism. The lenses apply gentle pressure to the cornea, flattening the steeper areas and allowing the cornea to take on a more spherical shape. This process, known as corneal molding, helps to correct the irregular curvature that causes astigmatism.
 

The Ortho-K lenses are worn overnight, and the cornea's shape is gradually adjusted over the course of several days or weeks, depending on the individual's response to the treatment. Once the desired corneal shape is achieved, the lenses can be removed during the day, and the corrected vision can be maintained without the need for glasses or daytime contact lenses.
 

The degree of astigmatism correction achieved through Ortho-K can vary from person to person. Individuals with mild to moderate astigmatism typically see the best results, while those with more severe astigmatism may not be able to achieve complete correction. Your optometrist can evaluate your specific condition and determine if Ortho-K is a suitable option for you.
 

The Process of Getting Fitted for Ortho-K Lenses

During your initial consultation, your eye doctor will perform a comprehensive eye examination to assess your vision, the shape and curvature of your corneas, and the overall health of your eyes. This information will help determine if you are a suitable candidate for Ortho-K.
 

Your doctor will use a specialized instrument called a corneal topographer to create a detailed map of the surface of your corneas. This information is used to design the custom Ortho-K lenses that will best fit your eyes and correct your astigmatism.
 

Once the Ortho-K lenses have been designed, your doctor will fit you with the lenses and evaluate their performance. This may involve several follow-up appointments to ensure the lenses are providing the desired vision correction and that your eyes are responding well to the treatment.
 

Throughout the Ortho-K treatment process, your doctor will closely monitor your vision and the shape of your corneas to make any necessary adjustments to the lenses or the treatment plan.
 

Is Ortho-K the Right Option for Correcting Your Astigmatism?

For many individuals with astigmatism, Ortho-K can be a highly effective and convenient vision correction solution. By temporarily reshaping the cornea, Ortho-K lenses can help to correct the irregular curvature that causes astigmatism, leading to clear, comfortable vision without the need for glasses or daytime contact lenses.
