The definitive intervention for restoring vision in cataract-affected eyes is which?

• A. Surgical removal
• B. Pharmacologic dissolution
• C. Laser therapy
• D. Observation

Answer: (A)

Removing the opaque lens surgically is the definitive way to restore vision in cataracts. A cataract clouds the lens, blocking and scattering light so images appear blurred and colors less vivid. The only reliable method to clear the visual path is to remove the cloudy lens and replace it with a clear artificial intraocular lens, which allows light to be focused properly onto the retina and typically improves visual acuity. Drug-based dissolution of cataracts isn’t effective for reliably removing the lens, especially in mature cases, and simply observing won’t improve vision. Laser techniques have roles in eye care—for example, treating certain issues after cataract surgery or helping fragment some material during the procedure—but they do not replace the need to remove the lens to restore sight.
