Question

If there is a fixed percent uncertainty in LASIK reshaping of the cornea, why would you expect those people with the greatest correction to have a poorer chance of normal distant vision after the procedure?

a) LASIK is not effective for high corrections.

b) LASIK induces additional vision problems.

c) The uncertainty affects vision negatively.

d) LASIK is more effective for high corrections.

Answer 1

The fixed percent uncertainty in LASIK reshaping of the cornea can result in a poorer chance of normal distant vision for people with the greatest correction.

Step-by-step explanation:

The reason that people with the greatest correction may have a poorer chance of normal distant vision after LASIK procedure is because of the fixed percent uncertainty involved in the reshaping of the cornea. LASIK reshapes the cornea to correct vision, but the uncertainty in the procedure means that the exact correction cannot be guaranteed. For people with a high degree of correction, even a small percent uncertainty can result in a significant difference in the final visual outcome. This is why LASIK may not be as effective for high corrections.
