Why the other options are wrong:

• options for reading glasses.: Glasses are affected by surgery, but the topic is surgical vision correction.
• options for surgery for cataract.: Cataracts are not the conditions named.
• options for contact lenses.: Contact lenses may become less necessary but are not the procedure options described.

Correct Answer: cornea.

Why this is correct: The report says laser procedures reshape the cornea. The retina is where light is directed, not the structure being reshaped.

Why the other options are wrong:

• retina.: The retina receives the light in the report's account; the cornea is the reshaped structure.
• lens.: The report names the cornea, not the lens, as the reshaped structure.
• eyelid.: Corneal tissue is described; reshaping the eyelid is not.

Correct Answer: eliminate the need for glasses.

Why this is correct: The report says the need for glasses or contacts can be reduced and, in some cases, might be eliminated. The question retains those limits.

Why the other options are wrong:

• make glasses more necessary.: The report describes reducing or eliminating the need, not making glasses more necessary.
• require patients to switch permanently from glasses to contacts.: No required permanent switch from glasses to contacts is described; either need may be reduced.
• have no effect on the need for glasses.: No effect does not match the possibility asked about: eliminating the need in some cases.

Correct Answer: the newest iteration of laser eye surgery.

Why this is correct: The report introduces small incision lenticule extraction, SMILE, as the newest iteration of laser eye surgery. This asks for its reported description.

Why the other options are wrong:

• a treatment for depression.: SMILE is an eye procedure in the report, not depression treatment.
• advice about happiness.: The acronym names a procedure; the report is not giving advice about happiness.
• a method for making contact lenses.: The method removes tissue through a small incision; it is not described as contact-lens manufacturing.

Correct Answer: postoperative dry-eye symptoms.

Why this is correct: The qualified report compares postoperative dry-eye symptoms after SMILE and LASIK. It does not recommend SMILE for every person with existing dry eyes and excludes severe dry eye.

Why the other options are wrong:

• patients' budgets.: No cost comparison or budget advantage is reported.
• the width of patients' eyes.: The report does not describe changing the width of the eyes.
• all complicated vision deficiencies.: The report does not establish an advantage for every complicated vision deficiency; its comparison here concerns postoperative dry-eye symptoms.
