Effectiveness of Diquafosol Prophylactic Therapy to Prevent Dry Eye Disease for Cataract Surgery Patients in Indonesia

Overview

The goal of this clinical trial is to determine the effectiveness of preventive therapy with diquafosol sodium 3% compared to sodium hyaluronate 0.1% to prevent dry eye disease in patient who will undergo cataract surgery. The main questions it aims to answer are:

• The percentage reduction in subjective symptoms and signs of dry eye disease after cataract surgery.
• The differences in the use of diquafosol sodium 3% and sodium hyaluronate 0.1% in improving dry eye disease signs in patients objectively.
• The tear osmolarity and matix metalloproteinase-9 (MMP-9) after the treatment.
• The difference in visual quality improvement assessed from higher order aberrations (HOA) and contrast sensitivity after administration of diquafosol sodium 3% compared to sodium hyaluronate 0.1%.

Participants will receive diquafosol sodium 3% or sodium hyaluronate 0.1% for 4 weeks before the cataract surgery and 21 days after the surgery, and will be:

• Interviewed regarding their identity, history of illness, and symptoms of dry eye disease.
• Examined by researchers: eye condition, contrast sensitivity using the Pelli-Robson diagram, keratograph, HOA, tear osmolarity, MMP-9, corneal sensitivity, tear break up time (TBUT) , fluorescein break up pattern (FBUP).

This examination will be carried out 4 times: on the first day before the research series, four weeks after giving therapy before cataract surgery, 21 days after cataract surgery, and 90 days after cataract surgery.

Description

The general objective of this study is to determine the effectiveness of preventive therapy with diquafosol sodium 3% compared to sodium hyaluronate 0.1% for patient who will undergo cataract surgery. The objective is being measure by the reducing symptoms and milder signs of dry eye disease and improving vision quality in post-cataract surgery patients.

1. Evaluate the percentage reduction in subjective symptoms and signs of dry eye disease after cataract surgery with diquafosol sodium 3% compared to sodium hyaluronate 0.1% in patients who want to undergo cataract surgery.
2. Evaluate differences in the use of diquafosol sodium 3% and sodium hyaluronate 0.1% in improving dry eye disease signs in patients objectively by examining the value of break up time, corneal sensibility, keratograph and FBUP
3. Evaluate tear osmolarity and MMP-9 after administration of diquafosol sodium 3% compared to sodium hyaluronate 0.1%
4. Evaluate the difference in visual quality improvement assessed from HOA and contrast sensitivity after administration of diquafosol sodium 3% compared to sodium hyaluronate 0.1%

Participants will receive diquafosol sodium 3% or sodium hyaluronate 0.1% for 4 weeks before the cataract surgery and 21 days after the surgery.

The steps of the research examination are as follows:

1. History
   • Comorbid dry eye disease and screening exclusion criteria (history of smoking, previous medical history, history of hypertension, history of diabetes mellitus, history of routine medication and history of recent surgery)
   • Ocular Surface Disease Index (OSDI) Questionnaire
2. Physical Examination

The examination is carried out with sufficient lighting, to see if the patient's eye has other eye surface disorders that can affect dry eye syndrome. Examination of disorders of the surface of the eyeball is carried out by inspection to see the patient's ability to blink, the eyelids, eyelashes and interpalpebral surface, performing an examination by lifting the upper upper eyelid superiorly, examination by pulling the eyelid to see if the eyelid looks drooping and checking In the fornix of the eye, emphasis is placed on the expression of the meibomian glands. The existence of a positive examination, describes the patient has a disorder of the eyeball surface. This examination determines whether the patient can undergo cataract surgery for research.

C) Supporting Examination

• Contrast sensitivity using the Pelli-Robson diagram, keratograph, HOA, tear osmolarity, MMP-9, corneal sensitivity, tear break up time, fluorescein break up pattern.

This examination will be carried out 4 times: on the first day before the research series, four weeks after giving therapy before cataract surgery, 21 days after cataract surgery, and 90 days after cataract surgery.
