Final answer:
The correct postoperative instruction after cataract surgery is to use the prescribed eye drops as directed. Patients are typically advised against wearing an eye shield at night, avoiding heavy lifting, and not rubbing their eyes to ensure proper healing. Appropriate intraocular lens (IOL) power depends on a patient's original prescription.
Step-by-step explanation:
The question pertains to postoperative care and understanding of instructions following cataract surgery. To answer the student's question directly: The client information indicating an understanding of the instructions is C) I will use the prescribed eye drops as directed. Following cataract surgery, it is critical for patients to use the prescribed eye drops to prevent infection and facilitate healing. The eye drops typically contain antibiotics and anti-inflammatory medications. It is also important to note that wearing an eye shield at night (A is incorrect), avoiding heavy lifting and strenuous activities immediately (B is incorrect), and not rubbing the eyes (D is incorrect) are parts of standard postoperative care to protect the eye and ensure proper healing.
Regarding the optical aspects provided as reference, cataract surgery involves replacing the cloudy lens with an intraocular lens (IOL). If a person is nearsighted, the power of the IOL is less than that of the removed lens. After cataract surgery with IOL implantation, distant vision can be clear, but reading glasses might be needed for near tasks, depending on the type of IOL and the pre-existing refractive error. For individuals with myopia (nearsightedness), corrective surgery such as LASIK involves reducing the curvature of the cornea to correct their vision. However, with a fixed percent uncertainty in LASIK procedures, there is a chance that perfect vision may not be achieved post-surgery, especially for those requiring great corrections.
