Ortho-K (Orthokeratology) Lenses
What Are Ortho-K Night Lenses?
Ortho-K lenses, also known as night-time contact lenses, are a safe and effective solution for vision improvement and myopia control for children to experience clearer vision without glasses/contact lenses during the day. Ortho-K can effectively slow the progression of myopia in children by approximately 50%.
Suitable for adults and children in Singapore, orthokeratology means the freedom to participate fully in sports and activities where glasses or contact lenses might be inconvenient.
Wondering if Ortho-K lenses are for you? Come in for a consultation! We'll check your eyes and explain how orthokeratology can give you and your child the freedom from glasses or contact lenses.
How Does Ortho-K Lenses Work?
Orthokeratology is a procedure aimed at vision improvement that uses specially designed lenses to reshape the cornea while you sleep. Here’s a closer look at how the process works:
Corneal Mapping: The process of designing Ortho-K lenses begins with corneal mapping, where we use a corneal topographer to create a detailed view of its shape and curvature.
Lens Design: Based on the corneal map, we design rigid, gas-permeable lenses that are safe for overnight use and designed to gently reshape the cornea. These lenses can help improve the cornea’s refractive properties and reduce the need for glasses or daytime contact lenses.
Overnight Wear: You wear contact lenses while you sleep, allowing your cornea to reshape throughout the night. This overnight process is comfortable and non-invasive. When you remove them in the morning, you’ll enjoy clear vision during the day time.
Benefits of Ortho-K Lenses
- Healthy Eye Habits: Adopting healthy eye habits is essential for maintaining good vision, and Ortho-K can help in this regard. Clinical studies show that Ortho-K can effectively slow the progression of myopia in children by approximately 50%, making it a great option for myopia control. Additionally, using Ortho-K lenses eliminates the risk of glasses breaking or contacts dislodging during sports and other activities, reducing the likelihood of eye injuries. Moreover, the daily lens cleaning routine associated with Ortho-K fosters proper eye hygiene, promoting overall eye health.
- Freedom and Convenience: With Ortho-K lenses, you can enjoy newfound freedom and convenience in your daily activities. Say goodbye to fumbling with glasses or worrying about losing contacts, whether you’re playing sports, swimming, camping, or dancing, you can engage in hassle-free fun. Experience clear vision anytime, anywhere; wake up ready to go, whether it’s for an early morning run or a spontaneous adventure. Additionally, using Ortho-K lenses could reduce your reliance on corrective eyewear, allowing you to embrace a more natural look and feel confident without glasses obstructing your view.
- Enhanced Performance and Confidence: Ortho-K lenses can help enhance your performance and confidence, particularly in sports and physical activities. With no worries about glasses falling off or contacts drying out, you can try to use your full potential on the field or in the gym. Additionally, going without glasses can boost your self-esteem, allowing you to feel more comfortable and confident in your appearance. Ortho-K lenses also provide a wider field of view, giving you unrestricted peripheral vision that helps improve depth perception and situational awareness.
Who is Suitable for Ortho-K Lenses?
Individuals Managing Myopia: Those with mild to rapidly progressive myopia (with or without mild astigmatism) can be potential candidates for Ortho-K lenses. The ideal age for managing myopia in children is between 6 and 12 years when progression is most pronounced.
Those Seeking Freedom from Glasses: Children and adults in Singapore looking to live without glasses can benefit from Ortho-K lenses. This option is particularly suitable for individuals who are not eligible for LASIK or have other reasons to avoid traditional corrective eyewear.
Active Individuals and Those in Challenging Environments: Sporty individuals or people working in dusty environments may find Ortho-K lenses particularly useful, as they offer clear vision without the discomfort or complications of regular contact lenses.
