After laser vision correction surgery (Femtosecond LASIK, SBK, LASEK/Epi-LASIK), vision does not rise to normal levels immediately, but requires a certain amount of time for recovery and adaptation process, usually from a few days to a few months. Overall, there are two types of surgery: first, corneal stromal cutting; second, superficial corneal surgery. The speed of vision recovery varies. Details are described below. I. Surgery with rapid vision recovery: called corneal stromal cutting, including: femtosecond LASIK, SBK and general LASIK surgery. Vision recovery is fast, with most patients regaining normal vision within 24 hours after surgery. Stable vision can be achieved at one month after surgery. Second, the surgery with slower recovery of vision: called corneal surface surgery, including: LASEK, Epi-LASIK, modified PRK surgery. The recovery of vision after this type of surgery is slow, usually taking about 7 days to return to normal vision, during which time the vision gradually recovers. The vision will fluctuate during the month after surgery, with good and bad days. Hormonal eye drops are usually needed to spot the eyes for 4-6 months. In addition, the speed of vision recovery depends on age, refractive adjustment of the eye, and the degree of myopia prior to surgery. In general, young people and those with low pre-surgical myopia have faster recovery; in addition, vision to see far away is recovered earlier than vision to see near (e.g. reading, seeing fine objects, etc.). Therefore, during the post-operative vision recovery process, special attention should be paid not to watch TV, computer, books and newspapers continuously for a long time, so as not to cause eye fatigue and discomfort. During regular checkups at the hospital after surgery, the doctor will carefully check the visual acuity and refractive power of the eyes and use some eye medications to help improve the visual acuity and stabilize the refractive power as needed.
