Question

Which type of patients should you avoid for Ortho-K?

a) Those with mild myopia
b) Patients with irregular corneal astigmatism
c) Individuals under 18 years old
d) Those with stable refractive errors

Answer 1

Ortho-K should be avoided for patients with irregular corneal astigmatism, individuals under 18 years old, and those with high and unstable refractive errors.

Step-by-step explanation:

Ortho-K, or orthokeratology, is a method of vision correction that involves the use of special contact lenses to reshape the cornea while you sleep. There are certain types of patients that should be avoided for Ortho-K:

1. Patients with irregular corneal astigmatism: Ortho-K works best for patients with mild to moderate myopia and regular corneal curvature. Patients with irregular corneal astigmatism may not achieve the desired vision correction with Ortho-K.
2. Individuals under 18 years old: Ortho-K is not recommended for children because their eyes are still developing and may not handle the overnight lens wear well.
3. Those with stable refractive errors: Ortho-K is generally not recommended for patients with high and unstable refractive errors. It is more suitable for patients with low to moderate myopia.

It's important to consult with an eye care professional to determine if Ortho-K is the right option for you.
