Why should a patient avoid straining after cataract surgery?

• A. It can increase intraocular pressure.
• B. It can cause infection.
• C. It may predispose to vision loss.
• D. It can cause dizziness.

Answer: (D)

Straining after cataract surgery is avoided to protect the healing eye by keeping intraocular pressure from rising. The surgical incision and surrounding tissues are still healing, and a sudden increase in pressure inside the eye from Valsalva-like actions can stress the wound, lead to wound leakage or bleeding, and potentially threaten the surgical outcome. That immediate risk to the incision and healing makes avoiding straining the most important reason for this guidance. Infection and vision loss can occur with postoperative complications, but straining is not the direct mechanism for those risks. Dizziness is not the primary concern related to the eye itself; the main issue is protecting the wound by preventing rises in intraocular pressure.
