Immediate Effects of Lipid-Based and Non-Lipid Artificial Tears on Corneal Aberrations

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.
