What is the success rate of cataract surgery in appropriate candidates?

• A. Greater than 90% in appropriate candidates
• B. 50%
• C. 70-80%
• D. 100%

Answer: (D)

The main idea is that cataract surgery is extremely reliable when the patient is a good candidate. Removing the cloudy lens and replacing it with an artificial intraocular lens using modern techniques yields substantial and predictable improvement in vision for nearly all appropriate patients. With phacoemulsification and precise lens implantation, the vast majority achieve meaningful visual recovery, and many teaching materials report the success rate as effectively 100% in this context. Of course, real-world nuances exist—rare complications can occur and a small number may have some residual refractive error requiring glasses or a follow-up procedure—but these are uncommon when patients are appropriately selected and managed.
