Hi Windy
You are absolutely suitable for corneal cross-linking. This is routinely performed as an adjuvant procedure in modern Lasik practices for certain patients who are at risk of biomechanical instability and subsequent regression or corneal ectasia, either due to thin corneas, extreme pre-surgery myopia or astigmatism.
Your surgeon may not have offered this previously if it was not indicated for you, the treatment was not available when you had your original surgery performed, or it was not available in the particular practice that you had your surgery.
Collagen cross-linking is not routinely offered to all patients, as it is associated with mild additional corneal inflammation, may cause post-operative haze and may require prolonged post-operative topical steroid treatment following this treatment. Not to mention the fact that it will also cost you an additional fee!
As it is becoming increasingly common place now, you should consider returning to your surgeon to have a discussion about whether cross-linking is indicated and suitable for you to have it performed now.
Best of luck!
