Group Intervention Description Arm 1; Humylub Ofteno® PF Sodium hyaluronate 0.1%/chondroitin sulfate 0.18% Humylub Ofteno® PF (sodium hyaluronate 0.1%/chondroitin sulfate 0.18%) ophthalmic solution applied QID for 30 days. Arm 2; Hyabak® Sodium hyaluronate 0.15% Hyabak® PF (sodium hyaluronate 0.15%) ophthalmic solution applied QID for 30 days. Arm 3; Lagricel Ofteno® PF Sodium hyaluronate 0.4% Lagricel Ofteno® PF (sodium hyaluronate 0.4%) ophthalmic solution applied QID for 30 days.
- Primary Outcome Measures
Name Time Method Change in Ocular Surface Disease Index (OSDI) Days: 0 (± 2) (eligibility visit), 17 - 19 (± 1) (first follow-up visit), and 31 - 33 (± 1) (final visit). It is a 12-item questionnaire used to evaluate symptoms associated with dry eye disease, as well as classify their severity. According the obtained score, categories are as follows: normal (0-12 points), mild (13-22 points), moderate (23-32 points), or severe (33-100 points).
- Secondary Outcome Measures
Name Time Method Change in conjunctival and corneal staining with lissamine green Days: 0 (eligibility visit), 17 - 19 (± 1) (first follow-up visit), and 31 - 33 (± 1) (final visit). The evaluation will take place after applying the lissamine green stain on the ocular surface and evaluating the resulting staining pattern. This will be measured through the Oxford scale which includes 6 grades: Absent (0), Minimal (I), Mild (II), Moderate (III), Marked (IV), Severe (V).
Noninvasive keratograph break-up time (NIKBUT) Days: 0 - 2 (baseline visit),17 - 19 (± 1) (first follow-up visit), and 31 - 33 (± 1) (final visit). This evaluation will be performed through an Oculus Keratograph 5M, and the parameter "first break-up time" will be recorded as NIKBUT. This study can take place within a time frame of 0 - 2 days between eligibility and baseline visits, and ± 2 of fist follow-up and final visits.
Change in conjunctival and corneal staining with fluorescein Days: 0 (eligibility visit), 17 - 19 (± 1) (first follow-up visit), and 31 - 33 (± 1) (final visit). The evaluation will take place after applying the fluorescein stain on the ocular surface and evaluating the resulting staining pattern. This will be measured through the Oxford scale which includes 6 grades: Absent (0), Minimal (I), Mild (II), Moderate (III), Marked (IV), Severe (V).
Incidence of related non expected adverse events Days: 0 (eligibility visit), 0 - 2 (baseline visit),17 - 19 (± 1) (first follow-up visit), 31 - 33 (± 1) (final visit), and 38 - 40 (± 1) (safety call). Presence/absence of related non expected adverse events.
Change in conjunctival hyperemia Days: 0 (eligibility visit), 17 - 19 (± 1) (first follow-up visit), and 31 - 33 (± 1) (final visit). Rate of conjunctival hyperemia will be evaluated through the Efron scale which includes 5 grades: Normal (0), Very Mild (I), Mild (II), Moderate (3), and Severe (4).
Change in Best Corrected Visual Acuity (BCVA) Days: 0 (eligibility visit), 17 - 19 (± 1) (first follow-up visit), and 31 - 33 (± 1) (final visit). With the patient's best possible refractive correction, visual acuity will be evaluated through the Snellen chart. Its notation (fraction or decimal) is described as the distance from the chart at which the test is performed, divided by the distance at which a letter equals vertically 5 minutes of arc.
Change in incidence of chemosis Days: 0 (eligibility visit), 17 - 19 (± 1) (first follow-up visit), and 31 - 33 (± 1) (final visit). Chemosis will be evaluated as present (if conjunctiva separates from the sclera in ≥ 1/3 of the palpebral opening area or if it exceeds the eyelid's gray line) or absent.
