Pre-Existing Ocular Disease
Patients with pre-existing ocular conditions such as blepharitis, meibomian gland dysfunction, or chronic dry eye are at a higher risk of developing dry eye syndrome after blepharoplasty. These underlying diseases can compromise tear production or eyelid health, making it more difficult for the eyes to recover following surgery.
Excessive Skin or Fat Removal
Surgical intervention that involves excessive removal of skin or fat can lead to complications like lower eyelid retraction and postoperative ptosis. Removing too much excess fat or skin may alter the natural support and position of the eyelid, disrupting eyelid function and contributing to dry eye symptoms.
Poor Eyelid Closure (Lagophthalmos)
Inadequate closure of the eyelids, particularly the upper lid, can result in lagophthalmos—a condition where the eyes do not close fully. This exposure increases tear evaporation and dryness, prolonging discomfort and potentially delaying healing after blepharoplasty.
Advanced Age
Older patients often experience droopy eyelids due to natural aging processes. This laxity can increase the risk of dry eye syndrome because the eyelids may not close completely or function optimally, making surgical outcomes more challenging to manage.
Female Patients
Women are generally more susceptible to dry eye syndrome, likely due to hormonal differences that affect tear production and eyelid tissue. This predisposition means female patients undergoing blepharoplasty should be carefully monitored for signs of dryness.
Use of Medications That Reduce Tear Production
Certain medications, including antihistamines, antidepressants, and diuretics, can reduce tear production and worsen dry eye symptoms after surgery. Patients using these drugs require special attention before and after blepharoplasty to prevent complications.
Aggressive Surgical Technique
Techniques such as the lateral tarsal strip procedure or lower eyelid blepharoplasty, when performed aggressively, can increase the risk of eyelid malposition and dry eye. Careful surgical planning is essential to avoid disrupting the delicate balance of eyelid anatomy and function.
History of Ocular Surgery or Trauma
Patients who have undergone reconstructive surgery, revision surgery, or primary surgery involving the eyes or eyelids are more vulnerable to dry eye syndrome after blepharoplasty. Previous interventions can weaken eyelid structures, complicating healing and tear film stability postoperatively.
