Eyelid Swelling After Lasik?

Undergoing LASIK surgery can be a life-changing experience, offering improved vision and freedom from glasses or contact lenses. 

However, some individuals may experience side effects following the procedure, one of which is eyelid swelling. 

While some swelling is entirely normal to be experienced, it’s essential to understand its causes, how to manage it, and what to expect during the recovery process.


What Causes Eyelid Swelling After LASIK?

  1. Surgical Trauma: LASIK involves the creation of a corneal flap, which can temporarily disrupt the normal anatomy of the eye. The body sends inflammatory cells to the area to promote healing. This leads to inflammation and swelling, including in the surrounding eyelids.
  2. Dry Eyes: Dry eye syndrome is a common side effect of LASIK, particularly in the early stages of recovery. When the eyes are dry, the body may produce excess tears as a protective mechanism, leading to puffy eyelids.
  3. Allergic Reactions: Some individuals may experience allergic reactions to the medications or eye drops used before, during, or after LASIK surgery. These reactions can manifest as eyelid swelling, redness, or itching.
  4. Pressure from the Instruments: Throughout LASIK, instruments such as the lid speculum, employed to keep your eyelids open, may exert gentle pressure on the eyelids, resulting in temporary puffiness.
  5. Pre-existing Conditions: Patients with pre-existing conditions such as blepharitis (inflammation of the eyelids), conjunctivitis (pink eye), or meibomian gland dysfunction may be more prone to eyelid swelling following LASIK.
  6. Infection: While rare, infection can occur following any surgical procedure, including LASIK. Infections can cause inflammation and swelling in the eyelids, along with other symptoms such as pain, redness, and discharge.
  7. Individual Variations: Post-surgery swelling can vary significantly among individuals, with some experiencing more pronounced swelling than others.


Battling the Bulge: Strategies for Minimized Swelling

  1. Follow Post-Operative Instructions: Your surgeon will provide specific instructions for post-operative care, including the use of prescribed medications and eye drops. It’s crucial to follow these instructions diligently to minimise the risk of complications, including eyelid swelling.
  2. Use Cold Compresses: Applying cold compresses to the eyes can help reduce inflammation and swelling. Use a clean, soft cloth soaked in cold water or a commercial cold pack wrapped in a cloth. Apply the compress gently to the closed eyelids for 10-15 minutes at a time, several times a day, as needed.
  3. Stay Hydrated: Drinking plenty of water can help maintain proper tear production and prevent dry eyes, which can contribute to eyelid swelling. Aim to drink at least eight glasses of water per day, or more if you live in a dry climate or engage in strenuous activities.
  4. Avoid Rubbing or Touching the Eyes: Rubbing or touching the eyes can exacerbate inflammation and increase the risk of infection. Avoid rubbing your eyes, and be mindful of touching them with unwashed hands. If you need to apply eye drops or medication, wash your hands thoroughly first.
  5. Elevating Your Head: When resting, elevate your head by using extra pillows to help discourage fluid accumulation around your eyes.
  6. Protect Your Eyes: Wear sunglasses outdoors to protect your eyes from UV radiation and environmental irritants, which can worsen eyelid swelling and other post-operative symptoms. Choose sunglasses with 100% UV protection and wraparound frames for maximum coverage.
  7. Reduce Eye Strain: Excessive screen time, prolonged reading, or extended exposure to bright lights can strain your eyes and exacerbate swelling. To alleviate this:
  • Take regular breaks from digital devices and activities that demand intense eye focus.
  • Practice the 20-20-20 rule: Every 20 minutes, look at something 20 feet away for at least 20 seconds to give your eyes a brief respite.
  • To diminish eye strain, make sure you have sufficient lighting when reading or using screens.
  • Consider using blue light filters on electronic devices to minimise eye fatigue.


Recovery Timeline

The timeline for recovery from eyelid swelling after LASIK can vary depending on individual factors such as age, overall health, and the severity of the swelling. 

In most cases, eyelid swelling should gradually improve within the first week following surgery, with significant improvement seen by the second or third week.

However, it’s essential to be patient and allow your body time to heal fully. Avoid strenuous activities, swimming, or exposure to dusty or smoky environments during the initial stages of recovery, as these can aggravate symptoms and delay healing.


When to Worry About Eyelid Swelling

While some degree of swelling is anticipated post-surgery, it’s essential to remain vigilant for signs that may indicate a more serious issue:

  • Severe or Prolonged Swelling: If swelling persists significantly beyond a week or is notably severe, it could signal an underlying infection.
  • Pain: While mild discomfort is common, intense or throbbing pain in the eye or eyelids warrants attention.
  • Redness: Heightened redness in the eye or around the eyelids, particularly if accompanied by pain or discharge, may indicate infection.
  • Blurred Vision: Sudden or persistent blurry vision that doesn’t improve with blinking requires immediate medical evaluation.
  • Light Sensitivity: While some sensitivity to light is expected initially, persistent or worsening sensitivity should be addressed promptly.

Should any of these symptoms manifest, it’s imperative to promptly contact your ophthalmologist (eye doctor). Early intervention can help prevent complications and facilitate optimal healing.



Eyelid swelling after LASIK is a common side effect that can occur for various reasons, including surgical trauma, dry eyes, allergic reactions, pre-existing conditions, and infection. However, with proper management and adherence to post-operative instructions, most cases of eyelid swelling resolve within the first few weeks following surgery.

If you’re considering LASIK surgery or have recently undergone the procedure and are experiencing eyelid swelling, it’s essential to consult with your surgeon for personalised guidance and support. By understanding the causes, managing symptoms effectively, and allowing adequate time for recovery, you can enjoy the benefits of LASIK with minimal discomfort and inconvenience.


Living Beyond Eyelid Swelling

While this blog post addresses eyelid swelling, it’s crucial to recognise that LASIK is a surgical procedure with various potential side effects. Before determining if LASIK is the appropriate vision correction solution for you, thoroughly discuss all potential risks and benefits with your ophthalmologist.
