Patient question: I am 33 years old and want to have femtosecond laser surgery Several hospitals I consulted Some said that I could do it and some said I couldn't do it The corneal topography map is red and I am now entangled.
Re: This picture is just a picture, please send me all the test results together.
Corneal topography is a commonly used test in ophthalmic diagnosis prior to myopia surgery, which provides morphological and parametric information on the anterior and posterior surfaces of the cornea. This test is very useful for assessing the overall condition of the cornea, but it is only one part of the diagnostic process.
In addition to the berlin map of the corneal topography, there are several other important tests that can provide a more comprehensive picture of eye health:
Refractive Quadruplet:
This test provides detailed information about the refractive power of the cornea, including the curvature of the cornea, astigmatism, and the difference in refraction between the anterior and posterior surfaces. The quadruple diagram of refraction provides a more complete picture of the refractive state of the eye and possible refractive errors.
Corneal biomechanics test: This is a test that evaluates the physical properties of the cornea, such as the elasticity and stability of the cornea. Corneal biomechanical data are important for diagnosing certain eye diseases (e.g., keratoconus) and are important for evaluation before surgery.
For a comprehensive ophthalmologic evaluation and the best ** plan, it is recommended that additional images of the corneal topography (quadtych) be provided along with the results of the corneal biomechanics examination.
Patient question: Myopia 675 left 725 right
Re: You are highly myopic and your corneal thickness and curvature are within normal limits, but the results of corneal biomechanics show some abnormalities, which may not be ideal. In addition, your examination shows that the thinnest point of the cornea and the highest point of the posterior arch are in the same place, which is a common feature of keratoconus. However, due to the relatively small diameter of your cornea, this condition can be a false positive.
When considering surgery**, if you want to have vision correction surgery, I recommend ICL (Intraocular Glasses) implantation surgery as the first choice. ICL surgery does not involve changes to the corneal structure, so it is a safer option for patients with suspicious keratoconus.
If you insist on laser surgery, it is recommended that you wait another six months and re-examine the results during this time to compare the results to see if there are any changes. If the results of the examination after half a year show no significant changes and the possibility of keratoconus is ruled out, then you can consider laser surgery.
In summary, given your condition and test results, performing laser surgery requires more careful consideration and additional observation time. ICL surgery may be a safer option that is more suitable for your current situation.
Patient question: I had a check-up last year and it was the same condition. Doctor, do you think this situation is suitable for surgery? What tests do I need to rule out keratoconus?
Re: You don't need to do any checking, just observe.
The recommendation for surgery is very clear from what I said in the above paragraph. If you want to do it, do ICL surgery.
Patient question: I don't really want to do ICL, I want to do a full femtosecond laser. But because of the data problem, it is particularly tangled.
Re: In your case, if you can, you won't have surgery, and if you want to, you will have ICL surgery.
There's no need to dwell on it, and you can't risk your own body.
