Most available ocular lubricants target the aqueous deficiency of the tear, restoring only this layer, leaving the tear lipid stratum deficient, as occurs in most patients with evaporative DED. An innovative propylene glycol-hydroxypropyl guar enriched with a phospholipid nanoemulsion (PG-HPG-PH-N) is indicated to restore deficiencies in both the lipid and aqueous layers of the tear film, and its composition was designed to increase lubricant retention on the OS. The purpose of this study was to evaluate, through the Ocular Surface Disease Index (OSDI) and clinical assessment, the treatment of patients who had DED due to aqueous deficiency arising from mixed or evaporative DED subtypes with a PG-HPG-PH-N ocular lubricant at a reduced frequency of twice a day, in a prospective, multicenter, and single-arm study.</p><p><strong>Methods: </strong>Patients were screened from days - 7 to 0, and from day 1 (baseline and first day of treatment) to day 28 of treatment with this lubricant.
