Orthokeratology Lenses: Myopia Solutions Beyond Glasses 

Orthokeratology—commonly referred to as Ortho-K—is a non-surgical procedure designed to correct refractive errors such as myopia (nearsightedness) and astigmatism. Unlike traditional methods, Ortho-K employs specially designed gas-permeable contact lenses worn overnight. This innovative method involves the gentle reshaping of the cornea, offering temporary alleviation from visual imperfections throughout the day.

In South Korea, Eyeonce Eye Clinic shines as a prominent institution for patients seeking transformative vision correction through Ortho-K. With Eyeonce’s adept eye doctors, Paik Dong Won and Jung Sae Rom, you will be provided with expert guidance and personalized care throughout your journey to a clearer vision.

Who needs Orthokeratology (Ortho-K)?

Ortho-K can be beneficial for various individuals who experience specific visual challenges like myopia. Here is a breakdown of who might benefit from Orthokeratology (Ortho-K):

  • Myopia Sufferers (Nearsighted Individuals) – Ortho-K is particularly advantageous for those with myopia or nearsightedness. If distant objects appear blurry, Ortho-K lenses can help reshape the cornea, providing clear vision without the need for glasses or daytime contact lenses.
  • Astigmatism Patients – Individuals with astigmatism, characterized by distorted or blurred vision at any distance, can find relief through Ortho-K. The lenses aid in correcting the irregular curvature of the cornea associated with astigmatism.
  • Active Lifestyles – Athletes and individuals with active lifestyles often find traditional glasses or daily contact lenses cumbersome. Otho-K offers the freedom to clear vision without the hindrance of eyewear during physical activities.
  • Professionals and Students – Professionals and students who spend extended hours in front of screens may benefit from Otho-K. The lenses can mitigate eye strain associated with prolonged use of electronic devices.
  • Those Seeking Myopia Progression Control – Orthokeratology has shown promise in slowing down the progression of myopia, especially in children. Parents concerned about their child’s increasing nearsightedness may consider Ortho-K as a proactive measure.
  • Individuals Uncomfortable with Surgical Options – Ortho-K provides a non-surgical alternative for those who are hesitant about undergoing surgical procedures for vision correction. The process is reversible, offering a level of flexibility not found in surgical interventions.
  • Those Looking for Overnight Results – Unlike some vision correction methods that take time to show results, Ortho-K users experience improved vision within a few days. This rapid turnaround makes it appealing for those seeking quicker outcomes.
  • Peripheral Vision Improvement Seekers – Individuals interested in enhancing peripheral vision may find Ortho-K beneficial. Users have reported an improvement in their overall field of vision, contributing to a more comprehensive visual experience.

About Us

How does Orthokeratology (Ortho-K) work?

Our skilled eye doctors at Eyeonce Dr. Paik Dong Won and Jung Sae Rom, understand the transformative power of Orthokeratology (Ortho-K), offering the following benefits:

  • Gas-Permeable Contact Lenses – Ortho-K involves the use of specially designed gas-permeable contact lenses. These lenses are crafted to allow oxygen flow to the cornea, ensuring comfort during overnight wear.
  • Reshaping the Cornea – The key to Ortho-K’s effectiveness lies in the gentle reshaping of the cornea, the transparent front part of the eye. The cornea is responsible for focusing light onto the retina. In cases of myopia or astigmatism, the cornea’s curvature is irregular, leading to blurry vision.
  • Overnight Wear – Patients wear the Ortho-K lenses overnight while they are asleep. The lenses exert controlled pressure on specific areas of the cornea, gradually changing its shape. This process is entirely painless, and users typically feel minimal discomfort during the initial adjustment phase.
  • Vision Correction – By morning, the cornea retains its reshaped form, providing temporary relief from refractive errors. The result is clearer vision without the need for glasses or daytime contact lenses.
  • Daily Maintenance – Patients are required to wear the Ortho-K lenses consistently to maintain the corrected vision. Regular check-ups with an eye care professional, such as Eyeonce Eye Clinic, ensure that the lenses continue to effectively reshape the cornea.

Choosing Ortho-K at Eyeonce means choosing a trusted partner in your journey to a clear vision.
