The main treatment for eyelid skin laxity is surgery, which includes: 1. Upper blepharoplasty: The surgery to correct upper lid laxity is called upper blepharoplasty, and the appropriate procedure can be chosen depending on the cause and clinical presentation. 1. In cases of simple upper lid skin laxity, only the lax skin is removed. 2. In cases of bulging orbital fat, or “swollen eyeballs “If the skin is not lax, only the skin is cut and the bulging fat is removed. 3. If the upper lid skin is lax with bulging orbital fat, both the lax skin and the bulging fat are removed. Lower blepharoplasty: The surgery to correct lower eyelid laxity and bags is called lower blepharoplasty. Based on clinical manifestations and anatomical features, eyelid bags can be divided into skin laxity, orbital fat bulge, orbicularis muscle hypertrophy and mixed type. At present, the main types of lower blepharoplasty are the external method via skin incision, the internal method via conjunctival incision and triangular skin excision.1.External method via skin incision: Suitable for patients with lax lower lid skin. If the patient’s lower lid skin laxity is not obvious and there are only bags under the eyes, an internal approach via the conjunctival pathway is feasible, i.e., the lower eyelid is turned over and an incision is made in the conjunctiva so that the orbital fat can be removed. Third, ptosis correction: Patients with true ptosis will also need to undergo ptosis correction to ensure that the normal height of the lid fissure is restored and the visual axis is exposed, meaning that the pupil is not covered by the eyelid. The most appropriate procedure is chosen based on the patient’s muscle strength, etc. For age-related ptosis, the usual options are levator shortening and levator folding.
