Orthokeratology, or orthoK, is a non-surgical vision correction method that uses specially designed gas-permeable contact lenses worn overnight to reshape the cornea temporarily. Upon waking, users can enjoy clear vision throughout the day without glasses or contact lenses. While orthoK is an innovative solution for myopia (nearsightedness) management and other refractive errors, it’s essential to weigh its advantages and disadvantages before considering it as an option.
Advantages of OrthoK Lenses
OrthoK lenses are worn only at night, freeing you from the need for glasses or contacts during the day. This is especially beneficial for individuals who lead active lifestyles or work in environments where glasses or contact lenses may be inconvenient or unsafe (e.g., athletes, swimmers, or construction workers).
Unlike LASIK surgery, orthoK is a non-invasive and completely reversible option. If you stop wearing the lenses, your cornea will return to its original shape within days, making it a safe choice for people not ready to commit to surgery.
OrthoK lenses have been proven to slow the progression of myopia in children. By reshaping the cornea and altering how light focuses on the retina, orthoK can help reduce the risks associated with high myopia, such as retinal detachment and glaucoma.
Since orthoK lenses are worn while you sleep, your eyes are exposed to less dryness and irritation caused by environmental factors like wind, dust, or prolonged screen use during the day.
While the upfront cost of orthoK lenses may be higher than traditional contact lenses, they can be a cost-effective solution over time, particularly for children requiring myopia management. The lenses are durable and typically last one to two years with proper care.
Disadvantages of OrthoK Lenses
Adjusting to orthoK lenses can be uncomfortable initially, as they are worn overnight and exert gentle pressure on the cornea. Most users adapt within a week, but the initial adjustment period may deter some.
Proper cleaning and handling of orthoK lenses are critical to preventing infections. This requires a commitment to daily maintenance routines, which may be challenging for children or busy adults.
The reshaping effect of orthoK lenses is temporary. If you skip a night or two of wearing the lenses, your vision may revert to its original state, leading to dependence on the lenses for consistent results.
The upfront cost of orthoK lenses can be significant, including fitting sessions and follow-up appointments. While they are durable, replacement lenses or adjustments can add to the overall expense.
OrthoK may not be effective for individuals with high levels of myopia, astigmatism, or other eye conditions. A comprehensive eye examination is required to determine if you’re a good candidate.
As with any contact lens, there is a small risk of infection if hygiene practices are not followed. Sleeping in lenses—albeit designed for this purpose—does slightly increase the risk compared to not wearing lenses overnight.
