Abstract

Background: One of the most prevalent conditions in ophthalmology clinics is dry eye, which causes symptoms of discomfort in the eyes, such as redness, dryness, pain, and a feeling of a foreign body. It also impairs night vision because of aberrant tear film function or a lack of tears.

Aim and objectives: To evaluate the differences in corneal higher-order aberrations between patients with dry eyes who received a 0.3% hydroxypropyl cellulose (methylcellulose) eye drop or a 0.2% sodium hyaluronate eye drop. to contrast the two and examine variations for every single eye drop.

Patients and methods: This prospective investigation includes thirty patients (60 eyes divided into two groups) with dry eyes at the El-Hussein outpatient Clinic from January 2021 to December 2023.

Results: Spherical aberration (SA), coma, and trefoil significantly decreased after treatment with the advantage of Hyfresh over Tear's guard. Thus, 0.2% sodium hyaluronate eye drops are highly recommended for dry eye patients with higher-order aberrations (HOAs).

Conclusion: Compared to 0.3% Hydroxy Propyl Methyl Cellulose eye drops (Tears guard), 0.2% Sodium Hyaluronate eye drops (Hyfresh) Patients with dry eyes had much less alterations in their corneal higher order aberrations.
