ParadoxDiff: Easy
Logic Breakdown
Passage Summary: A surgery designed to fix vision so people don't need glasses anymore doesn't always work for everyone.
Reasoning: RK surgery is intended to eliminate the need for corrective lenses by reshaping the cornea, yet some patients continue to require glasses or contacts after the procedure.
Analysis: The paradox here is the gap between the surgery's intended purpose and its actual results for a subset of patients. Since this is an 'EXCEPT' question, four of the answers will provide a plausible reason for this failure—perhaps the surgery has a margin of error, the eye changes over time, or the patient has other vision issues RK doesn't address. The correct answer will be the one that fails to explain why the surgery didn't result in perfect vision. Focus on identifying which options provide a technical or biological reason for the continued use of glasses.

Correct Answer
E
E is irrelevant to the discrepancy. Saying RK patients are as nearsighted as those who do not undergo RK does not explain why some people who did get RK still need lenses afterward. It describes who chooses RK, not why RK may fail to eliminate the need for glasses or contacts.
