Inclusion Criteria

age-related cataract without surgery history and dry eye symptoms history

Exclusion Criteria

diseases influencing tear secretion (such as Sjögren syndrome, Steve-Johnson syndrome, diabetes, thyroid disease, etc.); history of ocular surgeries or nuclear hardness IV and V, which required the use of larger phacoemulsification energy; use of drugs that affect tear secretion and stability (such as glaucoma medications, artificial tears, corticosteroid drugs, etc.); or presence of ocular diseases (such as Pterygium, blepharitis, uveitis, glaucoma, lacrimal apparatus, etc.).
