Effect of sodium hyaluronate eye drops on IOL-Master 700 measurement parameters in moderate and severe dry eye and non dry eye patients

Abstract

Objective To assess the changes in IOL-Master 700 parameters after administering sodium hyaluronate eye drops to moderate and severe dry eye and non-dry eye patients. Methods Non-randomized controlled clinical research was performed.Patients with moderate and severe dry eye and non dry eye were enrolled in this study, with 40 patients in each group.All patients underwent IOL-Master 700 bioassay before and 5, 10 and 15 minutes after the administration of 0.1% sodium hyaluronate eye drops.The differences in axial length (AL), central corneal thickness (CCT), corneal curvature, and intraocular lens (IOL) were compared before and after the administration.All subjects signed informed consent. Results In the dry eye group, the AL, CCT and IOL power were increased and the K1 were decreased at 5 and 10 minutes after administering sodium hyaluronate eye drops (P 0.05). Conclusions The IOL power of moderate and severe dry eye patients is increased at 5-10 minutes after administering sodium hyaluronate eye drops, and the IOL power of non-dry eye patients is decreased within 5 minutes after the administration.
