Question

Which one of the following is NOT an important routine preoperative test for cataract surgery?

1) Physical examination
2) Visual acuity test
3) Intraocular pressure measurement
4) Corneal thickness measurement

Answer 1

Corneal thickness measurement is not commonly required for cataract surgery preparation, whereas physical examination, visual acuity test, and intraocular pressure measurement are important preoperative tests.

Step-by-step explanation:

The preoperative test that is NOT commonly required for cataract surgery among the options provided is Corneal thickness measurement. A physical examination is necessary to ensure the patient's overall health status before any surgery. The visual acuity test is crucial for understanding the severity of the cataract and expected outcomes of the surgery. Measuring intraocular pressure is important to screen for conditions like glaucoma, which can impact surgical decisions, but is not specific to cataract surgery preparation. The measurement of corneal thickness is generally more relevant for refractive surgeries like LASIK rather than cataract surgery.
