Which of the following is a common postoperative instruction for a patient who underwent cataract surgery?

Following cataract surgery, patients are often instructed to limit head movement to help prevent complications that could arise during the recovery period. This instruction is crucial because excessive movement may put strain on the surgical site, potentially leading to issues such as increased intraocular pressure or displacement of the lens implant. By minimizing head movement, patients can promote proper healing and reduce the risk of postoperative complications.

In contrast, wearing protective eyewear is generally encouraged rather than avoided, making the first instruction counterproductive to recovery. Engaging in light reading is sometimes advised only after a certain recovery period, as it may not be appropriate immediately following surgery due to visual strain or other factors. Lastly, wearing sunglasses indoors can be beneficial to mitigate light sensitivity, but the advice typically varies depending on the patient's specific comfort and recovery stage. Therefore, limiting head movement stands out as a fundamental postoperative instruction essential for a safe and effective recovery process.
