ClinConnect Summary

This clinical trial is looking at how cataract surgery, specifically a procedure called phacoemulsification, affects tear production and eye dryness in patients. The goal is to understand the difference in tear film and its secretion before and after the surgery. Researchers want to see if the surgery helps improve dry eye symptoms for those who have cataracts.

To participate in this study, you need to be over 45 years old and have cataracts. However, people with certain eye problems, those taking specific medications that might affect tear production, or individuals with certain health conditions like diabetes or high blood pressure are not eligible. If you join the trial, you can expect to undergo tests to measure your tear production both before and after the surgery. This study is currently recruiting participants, and anyone interested should consider the eligibility criteria carefully.

Eligibility 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).
