Effects of upper eyelid blepharoplasty on ocular surface sensation and tear production

To evaluate the effect of upper eyelid surgery on ocular surface sensation and tear production.

Prospective, interventional, consecutive case series. Patients undergoing upper eyelid blepharoplasty or blepharoptosis repair were evaluated with measurements of their corneal sensation and tear production using a Cochet-Bonnet esthesiometer and the Schirmer 1 test without anesthesia, respectively. Measurements were obtained preperatively, and at 1 day and 1 month postoperatively.

Eleven patients (21 eyes) were enrolled in the study. There was a significant decrease in corneal sensation between the baseline and postperative day 1 (p < 0.01) and a significant increase between day 1 and month 1 after surgery (p < 0.01). There was no statistically significant difference in corneal sensation between the baseline and postoperative 1 month measurement (p > 0.05). There was no significant difference in tear production between baseline and postoperative day 1 (p > 0.05). There was a statistically significant increase in tear production between baseline and postoperative month 1 (p < 0.05). There was no significant correlation between corneal sensitivity and Schirmer 1 test preoperatively, at postoperative day 1, or at postoperative month 1 after surgery.

Upper eyelid surgery results in a temporary decrease in ocular surface sensation that returns to baseline after 1 month. Patients with pre-existing ocular surface dysfunction should consider aggressive treatments with lubricating drops and ointment, punctual occlusion, or anti-inflammatory therapy to accommodate the temporary effects on ocular surface sensation that result from upper eyelid surgery.
