Laser Corneal Refractive Surgery (LCR) is now a more mature and safer surgical technique that can correct refractive errors and improve patients’ vision, but patients may also experience complications such as cone cornea and eye infections after surgery. Laser corneal refractive surgery refers to a computerized laser beam that is accurately controlled by the energy of laser photons to cut the corneal tissue and change the curvature of the cornea, thus correcting refractive error and improving the patient’s vision. Currently this surgical method is safer and has less damage to the tissues within the eye, more stability, shorter recovery period and lower surgical risk. However, all surgeries have surgical risks. Complications such as conical cornea and eye infections can occur after laser keratomileusis, affecting the surgical results. It is recommended that post-laser keratomileusis patients follow the doctor’s instructions for care, have regular checkups, and consult the doctor promptly when discomfort occurs.
