How does dry eyes affect cataract surgery?

Dry eye disease occurs when your eyes don’t produce enough tears or work correctly. This can cause discomfort, irritation, and blurry vision. A dry eye can affect your recovery after cataract surgery. 

How do dry eyes affect cataract surgery?

1. Discomfort and Dryness:   Dry eye patients may experience more irritation or a gritty feeling after surgery. The tear film (a protective layer on the eye’s surface) may become unstable, worsening dry eye symptoms.
2. Post-Surgery Dry Eye:  Cataract surgery can temporarily exacerbate dry eye by affecting corneal nerves that control tear production. Some patients might experience longer-term dryness, so you must be prepared for potential changes in your condition.
3. Blurry Vision: A dry eye can cause unstable tears, leading to blurry or fluctuating vision after surgery. This can make it harder to achieve sharp vision.

How can dry eye be managed before surgery?

Recognising and managing dry eyes before cataract surgery is crucial. Depending on the severity of the condition, there are various options. Most cases of dry eyes can be effectively managed with artificial tears or lubricating eye drops.  Severe dry eyes may require a more personalised approach, such as anti-inflammatory eye drops or punctual plus insertion. Lid margin infections, known as blepharitis, should be treated with lid hygiene, warm compresses, or antibiotics, depending on the severity. Surgery may need to be postponed in some cases until the dry eye is under control.

How is dry eye managed after surgery?

After surgery, managing dry eye is crucial for healing.  You may have to continue with your artificial tears after surgery in addition to the other eye drops.  All eye drops should be started with fresh, unused bottles.  On occasion, your eye doctor may choose to use preservative-free eye drops after you have had cataract surgery.

Will dry eye improve after surgery?

While some dryness may persist, proper treatment of dry eyes can significantly improve your comfort and vision. With ongoing care and regular follow-ups, most patients experience better vision and relief from cataract symptoms. It’s essential to discuss preparing for cataract surgery with your doctor and managing dry eye for the best results!
