Epithelial abrasion after myopic laser surgery?
Hello Doctor: I have undergone laser surgery for my myopia, and it has been two months since the procedure.
My right eye has recovered quite well, but the surface of my left eye is still damaged.
Since the first month, my vision in the left eye has been declining; it was originally 1.5 and is now 0.8, while my right eye remains at 1.5.
The doctor suspects that the surface may be too dry, but despite frequently using lubricating eye gel and artificial tears, there has been no improvement for a week.
The doctor continues to advise me to use them more often, but I am left wondering where exactly it is still dry.
I am very concerned, so I am considering the following: 1.
Can I switch from regular artificial tears (which I use every 15 minutes) to a more moisturizing option like "Fresh Tears" (https://kb.commonhealth.com.tw/drugs/27743.html#data-1-collapse) and use it every half hour? 2.
Given the surface damage, can I also apply a gel like "Dian Er Ming" (http://www.fuchon.com.tw/files/223-1248-386812,c4927-1.php?Lang=zh-tw) before bed to help with wound healing? Thank you very much!

Hello JN: 1.
If you want to increase the frequency of instillation, you should use preservative-free artificial tears.
2.
At bedtime, it is better to use ointment-type eye medications, as they are more suitable than gels.

Managing post-LASIK epithelial issues can be a challenging experience, especially when dealing with dry eyes and fluctuating vision. It’s essential to understand the underlying causes of your symptoms and explore effective management strategies.
Firstly, it’s important to recognize that LASIK surgery can temporarily disrupt the corneal epithelium, leading to dryness and discomfort. The healing process varies from person to person, and while some may experience a swift recovery, others may face prolonged issues. In your case, it seems that your left eye is not healing as well as your right, which can be concerning.
1. Switching to More Hydrating Artificial Tears: You mentioned considering switching from standard artificial tears to a more hydrating option like "Fresh Tears." This is a reasonable approach, especially if you feel that your current artificial tears are not providing adequate relief. More hydrating artificial tears often contain ingredients that help retain moisture and provide longer-lasting relief. However, it’s crucial to consult with your ophthalmologist before making this change, as they can provide personalized recommendations based on your specific condition. If approved, increasing the frequency of application to every half hour may help alleviate dryness, but be cautious not to overdo it, as excessive use can sometimes lead to irritation.
2. Using a Gel at Night: Applying a gel like "Point and Bright" before bed can be beneficial for promoting healing, especially if you have epithelial defects. These gels are thicker than standard artificial tears and can provide a protective barrier over the cornea, helping to retain moisture overnight. This can be particularly helpful if you experience dryness while sleeping, which is common after LASIK. Again, it’s advisable to discuss this with your doctor to ensure it’s appropriate for your situation.
3. Monitoring Symptoms: Keep a close eye on your symptoms. If you notice any worsening of your vision or increased discomfort, it’s essential to reach out to your ophthalmologist. They may consider additional treatments, such as punctal plugs to help retain tears or prescription medications to reduce inflammation.
4. Hydration and Environment: Ensure you are well-hydrated, as systemic hydration can impact eye moisture. Additionally, consider your environment; dry air, especially from heating or air conditioning, can exacerbate dry eye symptoms. Using a humidifier in your home or office can help maintain moisture in the air.
5. Follow-Up Appointments: Regular follow-ups with your ophthalmologist are crucial. They can assess the healing of your cornea and make necessary adjustments to your treatment plan. If your symptoms persist, they may recommend further interventions, such as corticosteroid eye drops to reduce inflammation or other therapeutic options.
6. Patience and Care: Healing after LASIK can take time, and it’s essential to be patient with your recovery. Continue to follow your doctor’s advice regarding eye care and medication usage.
In summary, managing post-LASIK epithelial issues requires a multifaceted approach that includes appropriate use of artificial tears, potential use of gels, and regular communication with your healthcare provider. By staying proactive and attentive to your symptoms, you can help facilitate a smoother recovery process.
