Purpose:
The signs and symptoms of dry eye disease (DED) can affect the quality of life of patients. This study analyzes whether locking Y lateral canthopexy improves patients’ quality of life and in what way it does so (based on the ocular surface disease index questionnaire) and DED signs (measured by the fluorescein breakup time, tear osmolarity, Schirmer test, and corneal staining) in patients with DED caused by a eyelid malposition or impaired blink dynamics.
Methods:
This was a case-control study. Forty eyes of 20 patients with DED and lateral canthal disinsertion examined at the University Hospital La Ribera during a 1-year period from November 2016 to November 2017. The 40 eyes were divided into 2 groups: Group 1 eyes that underwent locking Y lateral canthopexy (i.e., a plication of the superficial lateral canthal tendon to the lateral orbital rim periosteum); and group 2 eyes that underwent observational treatment, without surgery. Symptoms and signs in OU were recorded separately at baseline and 1 month after surgery.
Results:
One month after surgery, the ocular surface disease index reduced in group 1 eyes when compared with those of group 2 (p = 0.001), fluorescein breakup time showed an improvement in the operated eyes (group 1) (p
