ABSTRACT
The goal of refractive surgery is to correct refractive error, allowing patients to be independent of spectacles or contact lens. Ideally, surgeons aim to accomplish this goal with a single procedure. However, variability in biological response to laser or incisional procedures compromise postoperative predictability and stability. Therefore, retreatment or enhancement is often necessary to achieve satisfactory results. Patients’ preoperative characteristics such as relatively thin cornea may also dictate that a combined procedure be performed to save the tissue and reduce the risk of postoperative ectasia. Various ocular surgeries may affect the refractive status of the eye. Refractive surgery has been increasingly used to improve the postoperative refractive errors. This chapter discusses the possible roles for LASEK after corneal surgeries.
