As with all cases of surgery, risks and complications must be managed to an acceptable degree. A surgeon would have to help the patient weigh the benefits vs the likelihood of complications before deciding on going ahead with surgery.
Fortunately, the overall risks of post-laser refractive surgery corneal weakening or corneal ectasia are very low. However, we are aware that certain types of cornea shapes or thickness may place that patient at a higher risk of corneal ectasia than the general population.
When this occurs, the surgeon has the option of choosing a treatment that has a lower risk of causing corneal ectasia. In your case, advanced surface ablation (e.g. epi-LASIK, PRK, LASEK) is preferred over LASIK for this reason. Collagen cross-linking is also offered to mitigate the risk of corneal ectasia.
