Orthokeratology (Ortho-K Lenses) Overnight Contact Lenses

Orthokeratology, commonly referred to as Ortho-K, is a non-surgical vision correction treatment that utilizes specially designed gas-permeable contact lenses.

These lenses are worn overnight to gently reshape the cornea, allowing for clear vision during the day without the need for glasses or traditional contact lenses.

How does Orthokeratology work?

The process begins with a thorough eye examination, during which our skilled optometrists will assess your vision and cornea shape. Based on the results, custom-fit Ortho-K lenses are created for your eyes.

When worn overnight, these lenses apply gentle pressure on the cornea, effectively reshaping it.

As a result, the light entering your eye is refracted correctly, correcting your vision. The effects of Ortho-K can last throughout the day, with many patients enjoying clear vision without any eyewear during their daily activities.

Who Can Benefit from Orthokeratology?

Children & Teenagers

Ortho-K is particularly beneficial for children and teenagers with myopia. Since myopia tends to worsen during childhood, early intervention can play a crucial role in slowing down it's progression.

Ortho-K also helps enhance their comfort and confidence in activities such as sports and social interactions.

Adults

Many adults also choose Ortho-K for convenience. Active lifestyles, including sports and outdoor activities, can make wearing glasses or traditional contact lenses impractical.

Ortho-K provides a freedom that allows adults to focus on their activities without the hassle of daily vision correction.

Individuals seeking non-surgical option

For those who are hesitant about surgical options like LASIK, Ortho-K presents a safe, reversible alternative. With it's non-invasive method, patients can experience better vision without committing to surgery.
