Comparing tear film before and after cataract surgery
Evaluation Of Dry Eye After Uneventful Phacoemulsification
This study looks at how cataract surgery affects the tear film in people's eyes to see if it changes their dry eye symptoms.

What this trial studies
This observational study aims to evaluate the differences in tear film and tear film secretion in patients undergoing phacoemulsification cataract surgery. It focuses on understanding how this common surgical procedure affects the ocular surface's tear film, which is crucial for eye health. The study will involve measuring the tear film's components before and after the surgery to assess any changes. By analyzing these differences, the research seeks to provide insights into the impact of cataract surgery on dry eye conditions.
Who should consider this trial
Good fit: Ideal candidates for this study are cataract patients aged over 45 years.
Not a fit: Patients with existing ocular surface diseases or those on medications that affect tear film production may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could help improve post-operative care for cataract patients by addressing dry eye symptoms more effectively.
How similar studies have performed: While there have been studies on dry eye and cataract surgery, this specific observational approach focusing on tear film changes is relatively novel.
Eligibility criteria
Show full inclusion / exclusion criteria
Inclusion criteria: * Cataract patients. * Cases within age \> 45 years old. Exclusion criteria: * Patients with ocular surface diseases and eyelid abnormality. * Patients receive ocular or systemic medications, that interfere with tear film production and stability (e.g. topical eye drops that contain preservatives, antihistaminic drugs, anticholinergic drugs, contraceptive pills). * Patients with systemic diseases like diabetes, HTN, rheumatoid arthritis. - Patients underwent previous ocular surgeries that interfere with tears instability or production (e.g. refractive surgery, keratoplasty, eyelid surgeries, pterygium excision). * Patients with a history of trauma, chemical burn, overusing contact lens (due to damaging the conjunctiva and the goblet cells, also corneal sensitivity reduction).
