EPILASIK [Overview] EPI-LASIK is a new refractive surgery technique developed on the basis of LASEK, which combines the advantages of both LASIK and LASEK and is gaining more and more attention from refractive surgeons. The epithelial flap is only 60 to 80 microns thick and is completely mechanically controlled, making it more precise than EK surgery. After laser cutting, the epithelial flap is reset and the procedure is complete. Patients will need to wear corneal contact lenses for about a week after surgery to prevent the ultra-thin epithelial flap from shifting. Postoperative pain is slightly more intense than LASIK-type surgery, but better than LASEK-type surgery. The difference between EPI-LASLK and LASEK】 Compared with LASEK surgery, EPI-LASIK is more precise and avoids the adverse effects of alcohol used in LASEK surgery, and the postoperative visual quality and comfort are greatly improved. EPI-LASIK also continues to be of great benefit to patients with sufficiently thick corneas, leaving more cornea for the patient and providing a higher level of safety. Patients should still try to choose this safer procedure if they are willing to tolerate a few days of mild pain.
