Can astigmatism be corrected?

In general, astigmatism can be corrected effectively.

Astigmatism primarily occurs due to differences in refractive power across various meridians of the eye, causing parallel light rays to refract through the eye and form two focal lines instead of converging on a single point. This results in symptoms such as blurred vision and double images. Through a professional eye examination, the degree and axis of astigmatism can be determined, and appropriately prescribed glasses can significantly improve vision and reduce discomfort caused by astigmatism. Additionally, contact lenses can provide more precise and stable correction by conforming closely to the cornea.

Furthermore, patients who are at least 18 years old and have stable refractive errors may consider refractive surgery. Options include corneal laser surgeries such as excimer laser and femtosecond laser procedures, which reshape the cornea by removing tissue to correct astigmatism. Another option is ICL (implantable collamer lens) surgery, which involves implanting a special artificial lens inside the eye to correct astigmatism and myopia, among other refractive errors.

Patients are advised to choose a suitable correction method based on their individual circumstances and professional medical advice to achieve optimal visual correction.
