The decision to stop Ortho-K should be made with your optometrist, and prescription and eye length should be closely monitored for possible regression.
Does ortho-k thin the cornea? Overnight orthokeratology causes rapid central corneal epithelial thinning and midperipheral stromal thickening. The consequent change in corneal sagittal height is the primary factor underlying the refractive effect of orthokeratology.

Is Ortho-K better than LASIK? Ortho-k has been clinically proven to slow the progression of myopia in children and young adults, making it an excellent treatment for nearsightedness. LASIK, on the other hand, offers no such benefits.
How many years does LASIK last?
LASIK can last a lifetime, 20 years, or 10 years. The lasting effects of the procedure depend upon multiple factors, including the age of the patient at the time of the procedure and medical conditions that one may develop as one ages that may affect eyesight.
Can Ortho-K reverse the myopia? Ortho-K is a long-term treatment with lenses that should be worn nightly. The benefit is that since they do their work at night, they do not need to be worn during the day. They also can completely reverse Myopia.
How long can you wear ortho-k lenses?
Typically, the vision-clearing effects of ortho-K contact lenses last up to 2 full days. During this period, the patient will be mostly or entirely free of the issues that previously plagued their vision. Keep in mind the ortho-K effect is temporary, especially in the early stages of treatment.
Is ortho-k better than LASIK? Ortho-k has been clinically proven to slow the progression of myopia in children and young adults, making it an excellent treatment for nearsightedness. LASIK, on the other hand, offers no such benefits.
How long does it take for cornea to return its normal shape?
Conclusions: : The results suggest that the anterior corneal surface is changed with the use of RGP contact lenses for one month, and it returns to its original shape completely within about 3 days if the contact lens use is discontinued.
How long can you wear Ortho K lenses?
Typically, the vision-clearing effects of ortho-K contact lenses last up to 2 full days. During this period, the patient will be mostly or entirely free of the issues that previously plagued their vision. Keep in mind the ortho-K effect is temporary, especially in the early stages of treatment.
Can I wear Ortho-K lenses during the day? For best results, patients are encouraged to wear their lenses while sleeping every night. Ortho-K lenses can also be worn during the day, but because they are reshaping the cornea, they are less comfortable for daytime wear than other types of contacts.

Can ortho-k correct astigmatism? Ortho-k can correct certain cases of astigmatism. For example, the clinical technique can treat only the corneal astigmatism component. Spherical ortho-k lenses only reshape the anterior surface of the cornea. It cannot change the profile of the refractive surfaces inside your eyes.
Can I use ortho-k after LASIK?
Yes, in many cases ortho-k can help with correcting refractive error left from lasik or RK. After treatment and maximum results are achieved, retainer lenses are worn to maintain the new corneal curvature.
Why is vision blurry after LASIK? Answer: Blurred vision after hours on the computer is generally due to dryness, which is common for six months after LASIK.
