Tear Film Evaluation After Phacoemulsification

To Investigate Tear Film Change After Phacoemulsification With SS-OCT

To compare tear film differences between surgical eyes and nonsurgical eyes in patients who had cataract surgery by phacoemulsification in one eye.

All participants granted their written informed consent to participate in the research protocol.

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.).
