Evaluation of the Protective Effect of an Ophthalmic Viscosurgical Device on the Ocular Surface in Dry Eye Patients during Cataract Surgery

초록

Purpose: To evaluate the protective effect of applying an ophthalmic viscosurgical device (OVD) to the ocularsurface during cataract surgery and its ability to prevent dry eye syndrome. Methods: Twenty-four patients aged 50 to 75 years who underwent cataract surgery at Seoul National UniversityBundang Hospital and agreed to participate in the study were included and divided into two groups: astudy group who underwent cataract surgery after application of an OVD to the ocular surface, and a controlgroup who underwent cataract surgery without application of an OVD. DisCoVisc was used as the OVD in thestudy group, while other factors including surgical techniques and administration of anesthetic agents wereperformed in both groups in the same manner. Indicators of dry eye syndrome including ocular staining score,tear break-up time, and tear osmolality were analyzed. Ocular surface disease index and a visual analog scalewere analyzed for dry eye symptoms, and the amount of balanced salt solution used during surface irrigationand operation time were also analyzed. Results: Significant improvement in the tear break-up time, corneal ocular staining score, and ocular surfacedisease index score in the study group compared with the control group one week after operation (by theMann-Whitney test). Use of OVD was associated with longer operating time. Conclusions: OVD applied to the ocular surface during cataract surgery had a protective effect on the ocularsurface one week after surgery.
