Laser eye surgery, particularly LASIK surgery, has become one of the most common and effective ways to correct refractive vision problems such as nearsightedness, farsightedness, and astigmatism. Over the years, advancements in technology and laser vision correction techniques have significantly reduced these procedures’ risks and side effects. However, while most patients achieve improved vision after LASIK surgery, some may experience headaches or other vision-related complications during recovery. Understanding the potential causes of headaches after laser eye surgery, how to manage them, and when to seek professional help is crucial for anyone considering or recovering from eye surgery.
This blog will explore the causes, symptoms, and treatment options for headaches after laser eye surgery. It will provide insights into the recovery process and practical advice for those experiencing tension headaches or other discomforts following LASIK or laser eye treatments.
What is LASIK Surgery?
LASIK (Laser-Assisted in Situ Keratomileusis) is a laser eye surgery designed to reshape the corneal tissue to improve vision. It is the most commonly performed type of refractive surgery and helps eliminate or reduce the need for contact lenses or glasses. During the LASIK procedure, a corneal flap is created, and an excimer laser is used to reshape the cornea. This allows light entering the eye to focus more accurately on the retina, thus improving vision.
The procedure typically takes only a few minutes, and most patients experience minimal discomfort during the treatment. However, like any surgery, LASIK has potential risks and side effects, some of which can result in temporary issues, such as headaches.
Why Do Some Patients Experience Headaches After LASIK Surgery?
Experiencing headaches after laser eye surgery is a relatively common occurrence, especially during the first few days or weeks following the procedure. While several factors can cause headaches, understanding their relationship to LASIK surgery can help in managing them effectively. Here are some of the most common causes:
1. Eye Strain from Adjusting to New Vision
After LASIK surgery, your eyes need to adjust to the new vision provided by the laser eye correction. This adjustment period can cause eye strain, especially if you’re engaging in activities that require intense focus, such as reading, working on a computer screen, or driving. The strain from trying to focus on visual information can lead to tension headaches.
During the adjustment period, the eyes may feel fatigued as they work harder to focus on objects. This is especially true if the eye surgery results in a small change in your prescription. The eyes might need time to adapt to their new focus, which can result in eye strain, leading to discomfort and headaches.
2. Dry Eyes and Discomfort
Dry eyes are one of the most common side effects of LASIK surgery. The laser eye treatment temporarily reduces tear production, leaving the eyes feeling dry, irritated, and uncomfortable. The dryness can sometimes be severe enough to affect vision and lead to headaches. Eye strain caused by dry eyes can exacerbate the discomfort, causing patients to squint or rub their eyes, leading to headaches.
To address this issue, patients may need to use lubricating eye drops or artificial tears to keep the eyes moist and reduce the sensation of dryness. Ensuring your eyes relax and stay hydrated is an important part of recovery.
3. Overexposure to Screens and Light

Screen time can lead to eye strain, and combining dry eyes, light sensitivity, and intense focus on digital screens can trigger headaches. This is why many eye doctors recommend limiting screen time and using sunglasses to reduce glare when outdoors.
4. Underlying Vision Issues
In some cases, headaches after laser eye surgery may be linked to underlying vision problems that were not fully corrected during the procedure. For example, refractive errors like astigmatism, myopia, or hyperopia may still be present after surgery, even if the laser surgery was technically successful. These residual vision problems can result in eye strain and headaches as the eyes try to compensate for the remaining refractive error.
If headaches persist after a successful LASIK procedure, it may be necessary to follow up with your eye doctor to ensure that the vision correction is adequate. Eye exams may help identify whether further correction is needed through another procedure or with corrective lenses.
5. Healing Process and Swelling
During the healing process after LASIK surgery, some swelling and irritation of the corneal tissue may occur. This swelling can cause blurred vision or visual disturbances, which may strain the eyes and lead to headaches. The discomfort caused by the healing process can cause tension in the neck and eyes, contributing to tension headaches.
Additionally, post-operative care instructions usually include using eye drops and medications to reduce inflammation, protect the corneal flap, and support eye healing. Following these instructions can help minimize the risk of complications and headaches.
6. Increased Pressure in the Eye
For some patients, the laser eye surgery may lead to increased intraocular pressure (IOP), which can cause discomfort and headaches. Increased eye pressure is a known risk of laser eye surgery, particularly in patients who may already be predisposed to conditions like glaucoma or increased eye pressure.
In these cases, headaches can be caused by the discomfort associated with the increased pressure inside the eye. If this occurs, it’s essential to contact your LASIK surgeon immediately to ensure that ocular pressure is properly managed during the healing process.
7. Post-Operative Inflammation
Some LASIK surgery patients may experience inflammation in the eye after surgery, especially in the first few days or weeks. Inflammation can contribute to blurred vision, eye strain, and headaches. While minor inflammation is a normal part of the healing process, significant or prolonged inflammation may require medical attention.
Your surgeon may recommend using anti-inflammatory eye drops to control inflammation and speed up the recovery process. Keeping the eyes moist and avoiding eye strain during the early recovery is essential for minimizing the risk of persistent headaches.
Managing and Preventing Headaches After LASIK Surgery
While headaches after LASIK surgery are relatively common, there are several steps you can take to minimize their occurrence and manage them effectively. Here are some tips for managing and preventing headaches after laser eye surgery:
1. Follow Post-Operative Instructions
After LASIK surgery, your surgeon will provide post-operative care instructions essential for the healing process. Be sure to follow these instructions carefully, including using eye drops as prescribed, avoiding strenuous activities, and protecting your eyes from excessive light or irritants.
2. Limit Screen Time
During the healing period, limiting your exposure to screens (such as computers, smartphones, and televisions) is important to avoid eye strain. Take frequent breaks to rest your eyes, and follow the 20-20-20 rule: every 20 minutes, take a 20-second break and look at something 20 feet away. This will reduce the strain on your eyes and help minimize headaches.
3. Use Artificial Tears and Lubricating Eye Drops
To alleviate dry eyes and irritation, use artificial tears or lubricating eye drops as your eye doctor recommends. These drops will keep your eyes moist and reduce the sensation of dryness that can contribute to headaches.
4. Stay Hydrated
Dehydration can worsen headaches, so drinking plenty of water during your recovery is essential. Staying hydrated helps keep your body in balance and can aid in reducing inflammation and eye irritation.
5. Wear Sunglasses Outdoors
Light sensitivity can be a common issue after laser eye surgery. Wearing sunglasses outdoors will help reduce glare and protect your eyes from intense light, reducing the chances of triggering headaches caused by photophobia.
6. Avoid Smoking and Alcohol
Both smoking and alcohol can hinder the healing process and increase the risk of complications after surgery. Smoking, in particular, can cause dryness and irritation in the eyes, while alcohol can dehydrate the body. Avoid these substances during your recovery to promote optimal healing and minimize discomfort.
7. Manage Stress and Tension
Stress and tension in the neck and shoulders can exacerbate headaches. Incorporating relaxation techniques such as deep breathing, meditation, or gentle stretching can help manage stress levels and reduce the likelihood of tension headaches.
When to Seek Medical Attention
While LASIK surgery and other laser eye treatments are generally safe and effective, there are certain situations where patients should seek immediate medical attention. After laser eye surgery, it’s important to monitor for any signs of complications that could indicate a problem with the healing process or a more serious underlying condition. Although many side effects, such as mild discomfort or blurry vision, are normal in the first few days to weeks of recovery, certain symptoms should not be ignored.
Below, we discuss when to seek medical attention after LASIK surgery and what signs to look for. Recognizing these symptoms early can help prevent long-term complications and ensure you get the appropriate treatment as quickly as possible.
1. Blurry Vision That Doesn’t Improve
It’s normal to experience blurry vision immediately after LASIK surgery as your eyes adjust to the changes made during the procedure. However, if your vision remains blurry or worsens over time, this could be a sign of complications. Common reasons for persistent blurry vision include:
- Dry eyes: Post-operative dryness can cause blurry vision. If you haven’t been using lubricating eye drops as recommended, this could cause the persistent blurriness.
- Under-correction or over-correction: In some cases, LASIK treatment may not fully correct the refractive error, leading to continued blurry vision.
- Corneal flap issues: If there was a problem with the corneal flap created during surgery, it may affect the healing process, causing blurry vision.
- Infection or inflammation: Eye infections could also cause blurry vision and require immediate attention from your eye doctor.
If your blurry vision persists beyond the typical recovery time or worsens, it’s crucial to consult with your LASIK surgeon or eye care provider as soon as possible to determine the underlying cause and correct it.
2. Increased Light Sensitivity (Photophobia)

- Persistent sensitivity to light could signal a corneal issue or infection.
- If photophobia is accompanied by significant pain or visual disturbances, this could be a sign of complications like corneal ulcers or glaucoma, and immediate medical attention should be sought.
Protecting your eyes from bright light by wearing sunglasses can help manage this condition during recovery. However, if your symptoms don’t improve, don’t hesitate to contact your doctor for advice.
3. Severe Eye Pain or Discomfort
Some eye discomfort is normal after LASIK surgery, such as mild irritation or a sensation of dryness. However, severe eye pain that persists or worsens is not typical and may indicate a complication. You should seek medical attention if you experience:
- Intense pain or throbbing in your eyes.
- Pain that doesn’t respond to over-the-counter pain relievers.
- Discomfort that doesn’t improve with artificial tears or eye drops.
Various factors, such as an infection, corneal scratch, or damage to the corneal flap may cause severe pain. If the pain is not managed by over-the-counter medication or if it worsens, it’s crucial to consult your LASIK surgeon for further evaluation.
4. Redness or Swelling in the Eye
Mild redness and swelling are common immediately after laser eye surgery as the body reacts to the procedure. However, if the redness or swelling becomes severe or does not subside within the typical recovery timeframe, it could indicate a serious infection or other surgical complications.
- Severe redness or increased swelling may indicate an eye infection or inflammation within the corneal tissue.
- If the swelling is associated with pain, or if you notice discharge from the eye (particularly yellow or green), this could indicate an infection that requires antibiotics.
Prompt consultation with your eye doctor is recommended if you experience persistent or worsening redness and swelling.
5. Flashes of Light or Double Vision
If you begin seeing flashes of light or experience double vision, it’s important to seek medical attention immediately. These visual disturbances can be signs of more serious complications, such as:
- Retinal tears or detachment: Flashes of light or double vision can sometimes indicate issues with the retina, such as a tear or detachment. This rare but serious complication can lead to permanent vision loss if not treated promptly.
- Corneal damage: If the corneal flap created during surgery becomes displaced or damaged, it can lead to distorted vision, including double vision.
- Increased eye pressure: Glaucoma or other eye pressure issues can cause visual disturbances, including flashes or a halo effect.
If you experience these symptoms, you must contact your LASIK surgeon or eye care provider immediately for an assessment.
6. Severe Headaches After Surgery
While headaches can occur during the adjustment period following LASIK surgery, severe headaches that don’t subside or worsen over time should be addressed. These headaches may be caused by:
- Eye strain due to the adjustment to new vision after LASIK surgery.
- Dry eyes can cause eye strain and headaches.
- Vision issues, such as under- or overcorrection of the refractive error, can strain the eyes and cause headaches.
If your headaches persist beyond the initial recovery period or become more severe, contact your LASIK surgeon or eye doctor for further evaluation.
7. Persistent or Worsening Dry Eyes

However, in some cases, dry eyes can persist or worsen, causing significant discomfort. If your eyes remain dry or you experience blurred vision or eye irritation despite using lubricating eye drops or following the post-operative care instructions, it may indicate an issue that needs medical attention.
8. Difficulty Seeing or Vision Changes
Suppose you notice sudden changes in your vision after LASIK surgery, such as a decline in clarity, persistent blurry vision, or even double vision. In that case, you should consult your eye doctor immediately.
These issues may be caused by residual refractive error, astigmatism, or dry eye. In rare cases, vision changes can be caused by complications such as retinal tears or glaucoma.
Conclusion
While headaches after laser eye surgery can be an uncomfortable part of recovery, they are generally temporary and resolve as your eyes heal and adjust to their new vision. You can minimise discomfort and promote a smooth recovery by following post-operative instructions, using appropriate treatments like artificial tears, and practicing good eye care.
If you experience persistent or severe headaches, it’s essential to consult your LASIK surgeon to rule out any complications and receive proper care. With the right approach, you can enjoy the long-term benefits of laser eye surgery, including improved vision and enhanced quality of life.
