Plain English Summary

Background and study aims
Cataracts are when the lens of your eye, a small transparent disc, develops cloudy patches. Cataract surgery involves replacing the cloudy lens inside the eye with an artificial one. Postoperative Dry Eye Syndrome (DES) often occurs after cataract surgery. Sodium hyaluronate eye solution is a common treatment for dry eye syndrome after cataract surgery. The aim of this study is to compare the efficacy of 0.15% sodium hyaluronate eye drops in MGD dysfunction and dry eye syndrome after cataract surgery in comparison with 0.1% sodium hyaluronate eye drops.

Who can participate?
Adult cataract patients with normal lid position and closure and not suffering from any eye diseases

What does the study involve?
Participants will be randomly allocated to use 0.15% or 0.1% sodium hyaluronate eye drops for 6 weeks following cataract surgery. Eye assessments are performed at each visit 1week before and 1, 3, 6 weeks after surgery.

What are the possible benefits and risks of participating?
There may be no risks or benefits for the participants. The eye drops are commercially available and have proven clinical safety.

Where is the study run from?
Pusan National University School of Medicine (South Korea)

When is the study starting and how long is it expected to run for?
February 2022 to December 2023

Who is funding the study?
Pusan National University Yangsan Hospital (South Korea)

Scientific titleEfficacy of 0.15% sodium hyaluronate on tear breakup time (TBUT), Schirmer's I test score, ocular surface disease index (OSDI) score, corneal staining score (CSS), lipid layer thickness (LLT) and meiboscore after cataract surgery: a randomized, double-masked study
Study hypothesis0.15% sodium hyaluronate might improve ocular surface status and dry eye syndrome in comparison with 0.1% sodium hyaluronate after cataract surgery.
Ethics approval(s)

Approved 06/05/2022, Pusan National University Yangsan Hospital Institutional Review Board (#20 Geumo-ro, Mulgeum-eup, Yangsan, 50612, Korea, South; +84 55 360 3854; pnyhirb@gmail.com), ref: 05-2022-084

ConditionDry eye syndrome, meibomian gland dysfunction
InterventionPatients are randomized using the random number method into two treatment groups.
The first group will use 0.15% sodium hyaluronate ophthalmic solution (Hyalu Mini®, Hanmi P harma Inc., Seoul, Korea) 4 times daily over 6 weeks following cataract surgery.
The second group receive standard postoperative treatment with 0.1% sodium hyaluronate (HyalQ, Ildong Pharmaceutical Inc., Seoul, Korea)
Eye assessments are performed at each visit 1 week before and 1, 3, 6 weeks after surgery.
Intervention typeDrug
Pharmaceutical study type(s)Dose response
PhaseNot Applicable
Drug / device / biological / vaccine name(s)0.15% sodium hyaluronate ophthalmic solution (Hyalu Mini®, Hanmi P harma Inc., Seoul, Korea) 0.1% sodium hyaluronate (HyalQ, Ildong Pharmaceutical Inc., Seoul, Korea)
Primary outcome measureMeasured at baseline (1 week before cataract surgery) and 1, 3, 6 weeks after cataract surgery:
1. Ocular surface status parameters:
1.1. Lipid layer thickness (LLT) measured using an interferometer
1.2. Schirmer’s type I test using COLOR BAR by Eagle Vision Inc.
1.3. Tear breakup time (TBUT), corneal staining score(CSS), meiboscore were measured by an ophthalmologist
2. Patients’ symptoms measured using Ocular Surface Disease Index (OSDI) questionnaire
Secondary outcome measuresThere are no secondary outcome measures
