Post-LASEK Care: Do You Need Sunglasses Indoors and at High Altitudes? - Ophthalmology

After undergoing LASEK surgery, proper post-operative care is crucial for ensuring optimal healing and visual recovery. One common question that arises is whether patients should wear sunglasses indoors and at high altitudes, particularly for those with pre-existing conditions like astigmatism.


Sunglasses Use Post-LASEK
1. Indoors vs. Outdoors:
- Indoors: While it is not strictly necessary to wear sunglasses indoors after LASEK, many patients find that their eyes are more sensitive to light during the healing process. This sensitivity can be exacerbated by artificial lighting, which may cause discomfort. If you experience discomfort or glare indoors, wearing sunglasses can help alleviate these symptoms. However, it is essential to ensure that the sunglasses are not too dark, as this can hinder your ability to see clearly and may not be advisable for indoor use.

- Outdoors: Wearing sunglasses outdoors is highly recommended after LASEK. The eyes are particularly sensitive to UV rays and bright sunlight during the initial healing phase. Sunglasses that block 100% of UVA and UVB rays will protect your eyes from harmful radiation and reduce glare, which can be uncomfortable and potentially harmful to your healing eyes.

2. High Altitudes:
- When it comes to high altitudes, such as climbing mountains over 3000 meters, wearing sunglasses becomes even more critical. At higher elevations, UV radiation is more intense due to the thinner atmosphere. This increased exposure can lead to a higher risk of sunburn on the eyes (photokeratitis) and other complications. Therefore, it is advisable to wear sunglasses that provide adequate UV protection when engaging in outdoor activities at high altitudes.


Additional Considerations
- Healing Process: After LASEK, the cornea undergoes a healing process that can take several weeks. During this time, it is essential to follow your surgeon's post-operative care instructions, which may include using prescribed eye drops, avoiding rubbing your eyes, and attending follow-up appointments to monitor your recovery.

- Activities: While you may be eager to resume your regular activities, it is advisable to avoid strenuous activities, including high-altitude hiking, until your doctor gives you the green light. The healing cornea can be sensitive, and high-impact activities may increase the risk of complications.

- Signs of Complications: Be vigilant for any signs of complications, such as increased pain, redness, or changes in vision. If you experience any unusual symptoms, contact your eye care provider immediately.


Conclusion
In summary, wearing sunglasses post-LASEK, especially outdoors and at high altitudes, is highly recommended to protect your eyes from UV rays and reduce discomfort. Indoors, the decision to wear sunglasses should be based on your comfort level. Always prioritize following your surgeon's advice regarding post-operative care and activity restrictions to ensure a smooth recovery. If you have any concerns or questions about your specific situation, do not hesitate to reach out to your eye care professional for personalized guidance.
