Safety and Efficacy of 2 Concentrations of Lubricin vs Sodium Hyaluronate in Ocular Discomfort After Refractive Surgery.
Italy30 participantsStarted 2017-06-17
Plain-language summary
The objective of this study was to evaluate tolerability, safety, permanence on the ocular surface and efficacy of Lubricin (20 and 50 μg/mL) eye drops vs Sodium Hyaluronate (Vismed®) 0.18% eye drops in patients with ocular discomfort following refractive surgery.
Primary objectives:
* Tolerability using a Visual analogue scale (VAS) for dryness, foreign body sensation, burning/stinging, itching, pain, stick feeling, blurred vision and photophobia;
* Treatment-emergent adverse events (TEAEs), assessed throughout the study.
Secondary objectives:
* Ocular surface vital staining with Fluorescein (Oxford scale)
* Schirmer-I test (without anaesthesia);
* Permanence of Lubricin on the Ocular Surface Tear film break-up time (TFBUT);
* Best corrected distance visual acuity (BCDVA);
* SANDE questionnaire scores - discomfort improvement entity;
* SANDE questionnaire scores - discomfort improvement speed;
* Signs evaluated by Slit lamp examination (SLE) (blepharitis, eyelid hyperemia/oedema, lashes, conjunctiva hyperemia);
* Intraocular pressure (IOP) ;
* Corneal sensitivity by Cochet-Bonnet aesthesiometry.
All parameters were evaluated at V1 (Day 1 - Baseline), V2 (Day 15±2) and V3 (Day 22±2/ETV).

Inclusion criteria
✓. Patients 18 years of age or older;
✓. Patients undergone ocular refractive surgery within 6 months from V1 - Day 1;
✓. Patients with ocular discomfort defined as SANDE score ≥ 30 at baseline;
✓. Average VAS score (dryness, foreign body sensation, burning/stinging, itching, pain, stick feeling, blurred vision and photophobia) ≥ 25 mm;
✓. Best corrected distance visual acuity (BCDVA) score ≥ 0.1 decimal units in both eyes at the time of study enrolment;

1
Changes From Baseline (Day 1 Pre-dose) in Ocular Tolerability Using a Visual Analogue Scale (VAS)
Timeframe: Day 1 (baseline = Visit 1) at pre-dose, 15, 30 min post-dose; Day 15±2 (= Visit 2) at pre-dose, 15, 30 min post-dose; Day 22±2 (= Visit 3)
2
Treatment-emergent Adverse Events (TEAEs) Assessed Throughout the Study
Timeframe: From baseline (Day 1 - pre-dose) to day 22±2
. Best corrected distance visual acuity (BCDVA) score of \< 0.1 decimal units in either eye at the time of study enrolment;
✕. Evidence of an active ocular infection in either eye;
✕. History or presence of ocular surface disorders other than ocular discomfort in either eye;
✕. Use of any ocular topical medication other than the study medications for the treatment of ocular diseases including artificial tears during the study period;
✕. Use of topical cyclosporine, topical corticosteroids or any other topical medication for the treatment of dry eye in either eye within 30 days of study enrolment;
✕. History of any ocular surgery (excluding laser or refractive surgical procedures) in either eye within 30 days before study enrolment. Ocular surgery will not be allowed during the study treatment period and elective ocular surgery procedures should not be planned during the duration of the follow-up period;
