Cataract surgery is one of the most common and successful surgical procedures performed worldwide. It involves removing the cloudy lens of the eye and replacing it with a clear artificial lens to restore vision. While the procedure is generally safe and boasts a high success rate, it is important to understand the potential risks and complications that may arise.

Common risks
As with any surgery, cataract surgery carries some risks, although they are rare. These include:

  • Infection (Endophthalmitis): This is a rare but serious complication where the inside of the eye becomes infected. Prompt treatment with antibiotics is crucial.
  • Inflammation: Mild swelling or redness is common post-surgery but usually resolves with prescribed anti-inflammatory eye drops.
  • Increased eye pressure: Some patients may experience elevated intraocular pressure, which is typically temporary and treatable.
  • Posterior capsule opacification (PCO): Sometimes referred to as a “secondary cataract,” PCO occurs when the lens capsule becomes cloudy after surgery. It is easily treated with a laser procedure called YAG capsulotomy.

Rare complications

  • Retinal detachment: This condition involves the retina pulling away from its normal position and requires immediate surgical intervention.
  • Macular edema: Swelling of the central retina (macula) can occur, affecting vision. Anti-inflammatory treatments are usually effective.
  • Lens dislocation: The artificial lens may move from its intended position, requiring additional surgery to correct.
  • Vision loss: In extremely rare cases, complications can lead to partial or complete vision loss.

Minimising risks
Choosing an experienced surgeon and following pre- and post-operative care instructions are key to minimising risks. Attending all follow-up appointments ensures that any issues are detected and addressed promptly.

Cataract surgery has transformed the lives of millions, offering clearer vision and improved quality of life. Understanding the potential risks and complications allows patients to make informed decisions and prepare for a smooth recovery.
