Issues related to prescription lens power caused by eye refractive errors and concerns regarding laser eye surgery?

Hello, doctor! My eye prescription fluctuates between 100 to 250 degrees (pseudomyopia), and there is a disparity of about 200 degrees between my eyes, with astigmatism of approximately left 175 and right 125.
I have previously undergone dilation.
However, after stopping medication for six months, my prescription increased from 200 to around 450 degrees.
Logically, I should be prescribed glasses with a strength of about 450 degrees, but I am unsure if it is due to the sensitivity of my eyes or another reason, as wearing glasses with exactly 450 degrees makes me very uncomfortable, even causing dizziness and blurred vision.
Even when I revert to my original glasses, which were possibly 200 degrees, if they lack blue light protection and stress-relief features, I still experience similar issues (my first pair of glasses, which I got at age 13, was 200 degrees and included blue light protection and stress relief, and I wore them for two to three years).
The subsequent glasses I have received cannot have any changes in prescription strength or features for blue light protection and stress relief, so I would like to clarify the following: 1.
Why am I experiencing these issues? 2.
Given my eye condition, once my vision stabilizes and all examinations are passed, am I a candidate for laser eye surgery? 3.
After undergoing laser eye surgery, is there a possibility that I will still experience the same dizziness or blurred vision issues? Thank you for addressing these three questions!

Hello:
1.
Why does this issue occur? Each person's eyes are unique, and vision problems can be influenced by multiple factors.
In your case, the changes in prescription and discomfort after wearing glasses may involve the eye's accommodative ability, corneal shape, or other factors related to the visual system.
These factors can lead to varying adaptability of the eyes under different prescriptions or wearing conditions, resulting in discomfort and symptoms such as dizziness.
It is recommended that you undergo a comprehensive eye examination by an ophthalmologist to understand the reasons behind your individual situation and potential solutions.
2.
Is laser eye surgery suitable for you? Laser eye surgery (such as LASIK or PRK) is typically used to correct vision problems like myopia and astigmatism.
However, whether the surgery is suitable for each individual requires a personalized assessment.
Factors such as stable vision, meeting age requirements, sufficient corneal thickness, and other eye health conditions are important considerations for determining surgical eligibility.
It is advisable to have a detailed eye examination to ascertain whether you are a candidate for laser eye surgery.
3.
Is it possible to experience dizziness or blurred vision after laser eye surgery? Laser eye surgery is generally safe and effective, but like any surgery, it carries certain risks and side effects.
Post-operative visual changes, dry eye symptoms, or light sensitivity are common short-term side effects, but these are usually temporary and can gradually improve.
Symptoms such as dizziness or blurred vision are rare after surgery but can occur.
A thorough pre-operative examination and discussion with your ophthalmologist will help assess your individual risks and expected outcomes.

Dear Weibor,
Thank you for your detailed inquiry regarding your vision changes and concerns following LASIK surgery. It's understandable to feel anxious about your eyesight, especially after undergoing a procedure intended to improve your vision. Let's address your questions and concerns systematically.

1. Understanding Your Symptoms: The symptoms you describe, such as blurred vision when looking at objects up close and a foggy appearance, could be attributed to several factors. One possibility is that you may have experienced overcorrection during your LASIK procedure, leading to a slight degree of hyperopia (farsightedness). This can happen if the cornea is reshaped too much, which may cause difficulty focusing on near objects. Additionally, if your cornea is uneven or if there are folds in the corneal flap created during surgery, this could also contribute to visual disturbances. It's essential to have a follow-up appointment with your ophthalmologist to assess the corneal surface and determine if any adjustments or treatments are necessary.

2. Potential for Improvement: Many patients experience fluctuations in their vision in the months following LASIK surgery. The healing process can take time, and your vision may stabilize as your eyes adjust. However, if your symptoms persist, it is crucial to discuss them with your surgeon. They may recommend additional treatments, such as enhancement procedures or other interventions, depending on the underlying cause of your symptoms.

3. Concerns About Laser Surgery and Vision Stability: Regarding your question about the possibility of undergoing LASIK again or other laser procedures, it is essential to have a thorough evaluation of your eye health. Factors such as the thickness of your cornea, the stability of your prescription, and the overall health of your eyes will play a significant role in determining your candidacy for further surgery. If your eyes are stable and healthy, you may be a candidate for enhancement procedures. However, if there are underlying issues, such as dry eye syndrome or corneal irregularities, these must be addressed first.

4. Post-Surgery Symptoms: It's important to note that while LASIK can significantly improve vision, some patients may still experience side effects such as glare, halos, or difficulty with night vision. These symptoms can sometimes resemble the issues you are currently facing. If you undergo another procedure, it is crucial to have realistic expectations and to discuss potential outcomes and risks with your surgeon.

5. Managing Dry Eye and Sensitivity: Given your history of dry eye and sensitivity, it is vital to manage these conditions before considering any surgical options. Artificial tears, punctal plugs, or other treatments may be necessary to ensure your eyes are adequately lubricated and healthy.

In conclusion, I recommend scheduling a comprehensive eye examination with your ophthalmologist to evaluate your current vision status and discuss your symptoms in detail. They can provide personalized recommendations based on your specific situation and help you understand the best course of action moving forward.

Best regards,
