After ptosis surgery, the upper lid of the affected eye will be improved compared to the pre-operative one, and the eye will be open, but when looking upward, the affected eye still cannot be lifted, so the affected eye becomes smaller when looking upward after surgery; when looking downward, the upper lid cannot fall back normally, so the affected eye is larger than the normal healthy eye when looking downward. 2. Due to the reduction of transient eye movements, the patient’s eyes usually appear dry or teary, so it is not advisable to look at the computer or cell phone screen for a long time, drive a car, etc. You can usually order some eye drops to treat dry eyes and lubricate the eyeballs. 3.Visit the hospital regularly to observe the condition of the cornea, and if there is discomfort, follow up at any time. 4. When you sleep at night, you will have incomplete eyelid closure, so you can apply some antibiotic eye ointment or gel inside your eyes when you sleep at night. 5. The principle of ptosis surgery is to fold the dysfunctional levator muscle, or to truncate and shorten it, or to suspend the upper lid over the frontalis muscle. In some patients, as time passes, the movement and closure of the eyelid, the extension and elongation of the muscle, and the loosening of the sutures may cause the upper lid to droop again, which usually happens months or years after the stitches are removed, but there are some patients whose recurrence is not There is no such thing as a never-returning ptosis surgery. The cost of surgery for ptosis is around $3,000 to $4,000 for a single eye, $5,000 to $10,000 for a plastic surgery department or a plastic surgery hospital or beauty salon, and $10,000 to $60,000 for a single eye in a private hospital or a high-end clinic. The procedures are the same: frontalis suspension, suspension of various tissue materials (allograft sclera, autologous broad fascia, allograft broad fascia, silicone strips, etc.), levator muscle folding, levator muscle shortening, and upper transverse ligament suspension. In addition these procedures generally require a combined blepharoplasty, regardless of future blepharoplasty, primarily to enable the surgical incision and scar to be hidden within the blepharoplasty sulcus.
