Can Cataract Surgery Correct Astigmatism?


Can Cataract Surgery Correct Astigmatism

Cataracts and astigmatism are two common vision problems that can significantly impact your ability to see clearly. While cataract surgery is well-known for restoring vision affected by cataracts, many wonder if it can also address astigmatism. The good news is that cataract surgery presents an excellent opportunity to treat both cataracts and astigmatism simultaneously.

What Are Cataracts?

A cataract refers to the clouding of the lens inside the eye, leading to blurred or distorted vision. Cataracts commonly occur due to aging, but they can also result from other factors including injury or underlying medical conditions such as diabetes. Cataract surgery is a safe and highly successful procedure to remove the cloudy lens and restore vision. 

What is Astigmatism?

Astigmatism is a common refractive error caused by an irregularly shaped cornea or lens. Instead of being perfectly round, the cornea or lens has a more oval or football-like shape, causing light to focus unevenly on the retina. This can result in blurred or distorted vision at any distance.

Can Cataract Surgery Correct Astigmatism?

  • Toric Intraocular Lenses (IOLs): Toric IOLs are specially designed lenses that can correct astigmatism. During cataract surgery, the clouded natural lens is replaced with a clear artificial lens, known as an IOL. Toric IOLs have different powers in different meridians of the lens, allowing them to compensate for the irregular shape of the cornea and provide clearer vision.
  • Limbal Relaxing Incisions (LRIs): LRIs are tiny incisions made at the edge of the cornea to reshape its curvature and reduce astigmatism. This technique can be performed in conjunction with cataract surgery to address mild to moderate astigmatism.
  • Laser Cataract Surgery: Advanced laser technology can be used to perform precise incisions during cataract surgery, including those needed to correct mild to moderate levels of astigmatism. Laser-assisted techniques offer enhanced accuracy and customization, potentially leading to better outcomes for patients with astigmatism.

Benefits of Correcting Astigmatism During Cataract Surgery

  • Improved Visual Acuity: Addressing astigmatism during cataract surgery can result in sharper and clearer vision.
  • Reduced Dependence on Glasses: Many individuals experience decreased reliance on glasses or contact lenses after cataract surgery with astigmatism correction.
  • Enhanced Quality of Life: Clearer vision can significantly improve daily activities such as driving, reading, and enjoying hobbies.
