1. Why is ptosis surgery difficult to perform? Ptosis surgery results vary tremendously, with some patients being very natural when done well and others not as good as they should be. So what other factors determine the outcome of surgery besides the severity of the condition? The first is the development of the surgical plan. Depending on the patient’s different degree of sagging, a reasonable surgical plan is used to obtain the best results. Secondly, the surgical technique is very important. Ptosis is a complex blepharoplasty procedure, so it is important to go to a larger hospital and find a specialist who specializes in blepharoplasty. It is important not to go to a small clinic for this surgery for convenience. 2. How is perfect ptosis surgery achieved? After a perfect ptosis surgery you can’t tell which eye was operated on. For patients under general anesthesia, it is difficult to achieve complete symmetry by relying entirely on experience.
