Ortho-K lenses, are commonly known as Orthokeratology lenses. These are the specially designed rigid gas-permeable contact lenses which are worn overnight to temporarily reshape the cornea. These lenses are customized based on the corneal topography measurements, establishing a precise fit that gently reshapes the cornea while sleeping. Upon waking and removing the lenses, the wearer can see clear vision throughout the day without wearing glasses or contact lenses.
Ortho-K lenses work by temporarily flattening the shape of cornea. This flattened cornea will then alter the phenomenon of light focusing upon retina and help in correcting refractive errors. This temporary reshaped cornea helps in correcting refractive errors and provides clear vision during waking hours. The effect of ortho-k lenses are reversible which means if the lenses are not worn, the cornea gradually returns back to its original shape.
These lenses are removed in the morning. The cornea stays flat for a while and your vision is corrected without the glasses. Once you stop using the lenses at night, your cornea will return to its original shape along with your refractive error. For best results, you have to wear the lenses regularly.
Ortho-K lenses plays a significant role in myopia control in children. Studies have shown that by using ortho-k lenses it is possible to slow down the progression of myopia in children, which makes it a valuable option for the parents to manage their child’s myopia progression effectively.
As per the theory, the light rays that enter through the peripheral cornea help in slowing down the myopia progression. Also, there will be a change in eye muscle postures which can also help in delaying myopia progression.
Ortho-K is considered one of the best options for candidates who are not suitable for LASIK or for those who doesn’t want to undergo LASIK. These lenses provide temporary vision correction without the permanence and risks associated with surgical procedures. Adults with mild to moderate myopia, hyperopia and astigmatism can be benefited from Ortho-K lenses. It is also beneficial for individuals who have jobs or hobbies that are incompatible with glasses or contact lenses, for example athletes or people working in dusty environments.

For getting Ortho-K lenses a comprehensive eye examination, including corneal topography is required. Once the lens is fitted, patients usually notice improvements in vision within the first few days to weeks of use. The degree of correction varies, with some individuals achieving 20/20 vision, while others may still need some visual aids for certain activities.
Regular follow-up visits are required to monitor the eye’s health and make sure the lenses are working correctly.

Ortho-K is considered a safe and effective treatment. However, like all contact lenses, there is a risk of complications such as eye infections, if the lenses are not properly maintained. It is important to follow the recommended cleaning and handling procedures and to have regular check-ups to minimize risks. Ortho-K lenses are FDA-approved for overnight wear, and numerous studies have demonstrated its safety and efficacy.
In conclusion, Ortho-K lenses offer a flexible solution for vision correction, especially for managing myopia in children and providing a non-surgical option for adults. Although these lenses requires a commitment to regular lens wear and care, the benefits in terms of improved vision and myopia control make it a worthy consideration.
