Immediate Effects of Lipid-Based Artificial Tears (Mineral Oil and Hydroxypropyl Guar) and Non-Lipid Artificial Tears (Hydroxypropyl Guar) on Corneal Aberrations in Healthy Individuals
In Brief
A Phase 4 clinical trial evaluating Lipid-Based Artificial Tear and Non-Lipid Artificial Tear for Aberration, Corneal Wavefront. Completed, enrolled 40 participants across 1 site.
Detailed Summary
This study evaluates the immediate effects of two types of artificial tear formulations on corneal aberrations in a healthy population. The interventions include a lipid-based formulation containing mineral oil and hydroxypropyl guar, and a non-lipid formulation containing hydroxypropyl guar alone. Participants will receive a single instillation of each formulation in separate eyes, with measurements of corneal aberrations taken before and 15 minutes after instillation. The study aims to compare the optical changes induced by these formulations and assess their impact on the ocular surface quality.

Timeline
Interventions
This intervention consists of a lipid-based artificial tear formulation containing mineral oil and hydroxypropyl guar. It is designed to enhance the tear film's lipid layer and improve ocular surface stability. Participants in this group will receive a single drop in each eye, and corneal aberrations will be measured at baseline and 15 minutes after instillation.
This intervention consists of a non-lipid artificial tear formulation containing hydroxypropyl guar. It is intended to stabilize the aqueous layer of the tear film and maintain optical quality. Participants in this group will receive a single drop in each eye, and corneal aberrations will be measured at baseline and 15 minutes after instillation.
