Which of the following is a potential complication following cataract surgery?

Cataract surgery is generally considered safe and effective, but as with any surgical procedure, it carries some risk of complications. Each of the mentioned complications can occur following cataract surgery.

Retinal detachment is a serious condition where the retina peels away from its underlying supportive tissue. It can occur after cataract surgery due to changes in the eye's inner structures and increased mobility of the vitreous gel, which may pull on the retina.

Corneal abrasion refers to a scratch on the cornea, which can occur if the protective barrier of the eye is compromised during surgery. This can happen due to surgical maneuvers or in the postoperative period if the eye is not adequately protected.

An increase in intraocular pressure (IOP) is another potential complication post-surgery. This can happen due to various factors, such as inflammation, retained lens material, or changes in the eye's drainage system following the procedure.

Recognizing that each of these potential complications is valid helps to understand that cataract surgery, while routine, is still associated with risks that must be monitored postoperatively. Therefore, choosing "all of the above" is appropriate, as it encapsulates the possibility of these varied complications arising after cataract surgery.
