Preventive laser surgery

I have high myopia and have noticed that upon waking up in the morning, one eye experiences a few minutes of black fog, which then returns to normal.
Occasionally, I also see flashes in my vision.
After visiting the hospital, the doctor assessed that my retina is too thin and recommended preventive laser treatment, which was performed on-site.
I recovered after one day and currently have no unusual symptoms.

1.
Is it necessary to perform preventive laser treatment if there are no holes in the retina?
2.
What are the most severe postoperative complications, and what symptoms should prompt immediate attention?
3.
Do I still need to use eye drops? Thank you for your response, doctor.

Hello: 1.
If the retina is thin and there is a history of high myopia, prophylactic laser treatment is a relatively common therapeutic approach.
This is because high myopia increases the risk of retinal detachment, which is a serious visual problem that can even lead to blindness.
Therefore, even in the absence of tears, a physician may recommend prophylactic laser treatment to protect the retina.
2.
Prophylactic laser treatment is a relatively safe procedure, but there are still some risks involved.
Possible side effects include blurred vision, eye pain, ocular infections, and retinal tears or breaks.
If severe pain, sudden vision loss, eye redness, or excessive eye discharge occur after the procedure, immediate medical attention should be sought.
3.
The physician will determine whether continued use of eye drops is necessary based on postoperative symptoms and findings.
Please follow the physician's advice and attend follow-up examinations as scheduled.

More Info

Preventive laser surgery, particularly for individuals with high myopia, is a topic of significant importance due to the associated risks of retinal complications. High myopia, defined as a refractive error greater than -6.00 diopters, can lead to various ocular issues, including retinal thinning, tears, and detachments. Here’s a comprehensive overview addressing your concerns about preventive laser surgery.

1. Necessity of Preventive Laser Treatment Without Existing Holes
The decision to undergo preventive laser treatment, even in the absence of retinal holes, is often based on the assessment of risk factors. High myopia inherently increases the risk of retinal complications due to the elongation of the eyeball and thinning of the retina. If your ophthalmologist has identified that your retina is particularly thin, they may recommend preventive laser treatment to fortify the retina and reduce the risk of future tears or detachments.
While some practitioners may argue against unnecessary procedures, the consensus is that if there are identifiable risk factors (like retinal thinning), preventive measures can be beneficial. The laser treatment creates a barrier around the vulnerable areas of the retina, potentially preventing future complications. Therefore, if your doctor has recommended it based on your specific condition, it is likely a prudent choice.

2. Potential Severe Complications and Warning Signs
As with any surgical procedure, there are risks associated with laser treatment. The most severe complications can include:
- Retinal Detachment: Although the procedure aims to prevent this, there is still a risk that it could occur post-operatively.

- Vision Loss: This can occur if there are complications during or after the procedure.

- Intraocular Pressure Changes: This can lead to glaucoma if not monitored.

Signs that require immediate medical attention include:
- Sudden increase in floaters or flashes of light.

- A shadow or curtain effect in your peripheral vision.

- Sudden loss of vision or significant blurriness.

If you experience any of these symptoms, it is crucial to contact your ophthalmologist immediately.

3. Post-Operative Care and Eye Drops
Post-operative care is essential for a successful recovery. Your ophthalmologist may prescribe eye drops to help with healing and to prevent infection. These drops may include:
- Antibiotic Drops: To prevent infection.

- Anti-inflammatory Drops: To reduce inflammation and discomfort.

It’s important to follow your doctor’s instructions regarding the use of these medications. Regular follow-up appointments will also be necessary to monitor your recovery and ensure that no complications arise.

Conclusion
In summary, preventive laser surgery can be a valuable option for individuals with high myopia, especially when there are risk factors like retinal thinning. While the procedure is generally safe and effective, it is essential to be aware of the potential complications and to recognize warning signs that require immediate attention. Always maintain open communication with your ophthalmologist, follow their recommendations regarding post-operative care, and ensure regular check-ups to monitor your eye health. Your proactive approach to managing your eye condition is commendable, and with proper care, you can help safeguard your vision for the future.
