Refractive Error
Refractive error is the condition that the parallel rays can not focus on the retina to form a clear image (nearsightedness, farsightedness and astigmatism).
 
Complications of High Myopia
High myopia is the diopter above 600. except of blurred vision, high myopia will trigger serious complications. Most of the complications will cause blindness.
The incidence rate of causing posterior staphyloma is 77%
How to Correct Refractive Error?
- Frame glasses
- Laser surgeries
- ICL (Implantable Collamer Lens)
- MCT/RGP
- Posterior scleral reinforcement
