B) Centrally fitted only

D) Fitted perfectly in one eye, slightly off in the other

Answer 1

Ortho-K lenses cannot be dispensed if they are too loose or overly tight in fitting.

Step-by-step explanation:

The question is related to the fitting of Ortho-K lenses. Ortho-K (orthokeratology) is a non-surgical procedure that uses specially designed contact lenses to temporarily reshape the cornea and correct vision. The correct answer is A) Too loose or overly tight.

Ortho-K lenses need to have a proper fit to achieve the desired corneal reshaping effect. If the lenses are too loose or overly tight, they will not provide the necessary pressure to reshape the cornea. It is crucial for the lenses to have a precise fit to ensure the correct correction of vision.

For example, if the lenses are too loose, they may not exert enough pressure to reshape the cornea effectively. On the other hand, if the lenses are overly tight, they may cause discomfort and potentially damage the cornea. Therefore, it is essential for an Ortho-K lens to be fitted neither too loose nor overly tight.
