The hyperplasia period, or scar growth, after eye opening disappears about 3-6 months after surgery. Scar growth has a lot to do with the incision in the corner of the eye. Generally speaking, the medial incision is the most prone to growth problems. In particular, the inner corner of the eye is more tense compared to the outer corner of the eye. The scar growth effect is most pronounced in the upper, lower and inner corners of the inner eye. After an eye opening, a relatively long recovery process is required. Usually the most severe period of scar growth is within 1-2 months after surgery, after 3 months the scars gradually improve, and after 6 months the scars are no longer visible. Due to the different body types of patients, there is also the problem of individual patients having a longer recovery period, which may take 1-2 years. It is recommended that patients with open eyes be promptly coated with anti-scar medication after surgery, keeping 1 time each in the morning and evening, which can be very effective in repairing as well as shortening the scar proliferation period.
