The Pattern of Dry Eye Disease After Cataract Surgery
This study is designed to explore dry eye disease (DED) pattern: ocular surface, corneal morphological changes, patients' subjective assessment of DED and their correlations with ocular surface inflammation, pain biomarkers after cataract surgery according to ocular surface lubrication with artificial tears during long-term follow-up.
- EligibilityCriteria: Inclusion Criteria:  Cataract patients from 50 to 90 years old who underwent uncomplicated phacoemulsification performed by one (and same) experienced surgeon.

Exclusion Criteria:  Patient expressed his wish to not participate in the study or discontinue it when already enrolled. Severe dry eye disease diagnosed with OSDI/DEQ-5 and at least one of the following tests: TBUT less than 10 seconds, tear osmolarity higher than 308 mOsm/l or positive corneal staining. Glaucoma. Diabetes mellitus. Systemic connective tissue disease, autoimmune disease. Neurologic conditions including stroke, Bell's palsy, Parkinson's, trigeminal nerve dysfunction. Patients who underwent refractive surgery (LASIK or PRK). Contact lens users. One or more of the following concomitant medications: psychiatric medicines, antihistamines and/or hormonal replacement.
