Can cataract surgery eliminate astigmatism?

Cataract surgery can correct certain degrees of astigmatism, particularly corneal astigmatism, which may be addressed through surgical planning. However, not all types of astigmatism can be fully resolved, and residual astigmatism after surgery may require corrective eyeglasses. If persistent symptoms such as blurred vision or eye pain occur after surgery, prompt medical attention is recommended.

During cataract surgery, an artificial intraocular lens (IOL) is implanted. By selecting specially designed IOLs or adjusting the location and size of the surgical incision, surgeons can correct pre-existing corneal astigmatism. Most patients experience a significant reduction in astigmatism and improved vision following surgery.

However, the surgical correction effect is limited for lenticular astigmatism or high irregular astigmatism, and complete elimination may not be possible. Postoperative astigmatism levels also depend on individual eye healing; some patients may have mild residual astigmatism, requiring prescription glasses after postoperative refraction to further improve vision.

After surgery, maintain good eye hygiene by avoiding eye rubbing and preventing water contamination. Reduce screen time on electronic devices and avoid direct exposure to bright light. Maintain a balanced diet rich in protein and vitamins, follow a regular sleep schedule, and avoid excessive eye strain to promote recovery.
