Evaluation of Sodium Hyaluronate Lubricating Drops Used before Insertion of Contact Lenses on Symptomatology, Severity, and Intensity of Ocular Dryness

Abstract EN

Purpose.

This study aimed to evaluate outcomes from the use of a sodium hyaluronate (SH)-based comfort drop, instilled before the insertion of contact lenses, in a population of symptomatic contact lens wearers.

Methods.

This was a cross-over, open-label, multi-sites study.

Subjects were fitted with silicone hydrogel lenses and followed for two months.

Before insertion of the lenses, SH drops was instilled in the lens for half of the group.

The other half did the same on the second month.

Objectives and subjective outcomes were measured and compared before from baseline with the ones collected after usage of SH drops.
