Regression refers to the eye returning back to its original state. Just to clarify, LASIK is a permanent surgery that removes tissue from your cornea thus the eyes technically will not revert to its original state. Although rare, it is still possible for your vision to change after a refractive surgery.+
Here are some ways to lessen the risk of regression after LASIK.
- Ensure your prescription has stabilised proceeding with surgery
- Using prescribed post operative medicated eyedrops diligently
- Studies have shown that patients with higher prescription or astigmatism have a higher risk of regression. You may be on medication longer post-lasers or your doctor may recommend you to go for collagen cross-linking to further strengthen your cornea. It is important to discuss with your ophthalmologist to find out your risk of regression before surgery
It is important to note that the eye is a living thing and that having LASIK does not make it less vulnerable to ageing and wear and tear.
