Investigation of Preservative-Free Ophthalmic Solution in Ocular Dryness
Study Details
Study Description
Brief Summary
This is a multicenter, prospective, observational, open-label, non-interventional study evaluating the clinical performance and the safety of 4 daily instillations of the ophthalmic solution in the treatment of eye discomfort, in particular due to eye dryness

Detailed Description
Primary objective
▪ To evaluate the clinical performance of Eyestil SYNFO® as detected by the reduction of keratitis lesions objectified by corneal and conjunctival staining tests with fluorescein using the National Eye Institute (NEI) scale after 1 month of treatment compared to baseline.
Secondary objectives
-
To evaluate the mean change of the corneal and conjunctival staining score with fluorescein using the NEI scale after 14 days of treatment and after 3 months of treatment compared to baseline.
-
To evaluate conjunctival hyperemia index assessed by OCULUS Keratograph after 14 days, 1 month and 3 months of treatment compared to baseline.
-
To evaluate the tear film stability as objectified by the tear film break-up time (TFBUT) test after 14 days, 1 month and 3 months of study treatment initiation compared to baseline.
-
To evaluate the changes on the Best Corrected Visual Acuity (BCVA) measured by the "Early Treatment Diabetic Retinopathy Study" (ETDRS) after 14 days, 1 month and 3 months of study treatment initiation compared to baseline.
-
To compare patients reported outcomes with baseline, using specifically:
-
the patient's reported Symptom Assessment questionnaire iN Dry Eye (SANDE) after 1 and 3 months of treatment;
-
the patient's Dry Eye-Related Quality-of-Life Score (DEQS) questionnaire after 1 and 3 months of treatment.
-
To evaluate the safety and compliance of the medical device throughout the entire study period.

Outcome Measures
Primary Outcome Measures
- Keratitis lesions [1 month]
To evaluate the clinical performance of Eyestil SYNFO® as detected by the reduction of keratitis lesions objectified by corneal and conjunctival staining tests with fluorescein using the National Eye Institute (NEI) scale after 1 month of treatment compared to baseline.
Secondary Outcome Measures
- Keratitis Lesions [Day 14 and at 3 months]
To evaluate the mean change of the corneal and conjunctival staining score with fluorescein using the National Eye Institute scale compared to baseline.
- Conjuctival Hyperemia [Day 14, 1 month and 3 months]
To evaluate conjunctival hyperemia index by OCULUS keratograph
- Best Corrected Visual Acuity [Day 14, 1 month and 3 months]
To evaluate changes in Best Corrected Visual Acuity (BCVA) using the Early Treatment Diabetic Retinopathy Study (ETDRS) Best Corrected Visual Acuity (BCVA) letter score.
- Tear Film Stability Break-Up time [Day 14, 1 month and 3 months]
The conjunctival tear film stability break-up time (TFBUT) will be evaluated after the instillation of 5 µl of a 2% preservative-free sodium fluorescein solution into the inferior conjunctival cul-de-sac- of each eye. The TFBUT value will be the average of 3 measurements.
- SANDE Questionnaire [1 and 3 months]
To compare patients reported outcomes with baseline, using the Symptom Assessment questionnaire iN Dry Eye (SANDE) questionnaire
- DEQS Questionnaire [1 and 3 months]
To compare patients reported outcomes with baseline, using the Dry Eye-Related Quality-of-Life Score (DEQS) questionnaire
- Number of Adverse Events [From date of randomization up to 3 months]
To evaluate the safety through general assessment of adverse events
- Investigator Global Assessment Score [From date of randomization up to 3 months]
To evaluate the safety using the Investigator Global Assessment Score
- Intra Ocular Pressure [From date of randomization up to 3 months]
To evaluate the safety using the measurement of the intraocular pressure
- Number and status (empty/unused) of returned devices [Day 14, 1 month and 3 months]
To evaluate compliance based on treatment administration and returned medical devices
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Male or female subjects aged 18 years or older
-
Subject able to provide Informed Consent, in compliance with Good Clinical Practice and local laws (thus, subject able to comprehend the full nature and purpose of the study, including possible risks and side effects)
-
Subjects with ocular discomfort resulting from eye dryness in one or both eyes as determined by:
-
Scoring of ocular surface staining with fluorescein using the NEI scale (summing the score of cornea and conjunctiva, the total score per single eye range should be at least ≥6 on the 0-33 NEI scale)

-
Sjögren's syndrome
-
Stevens-Johnson syndrome
-
Concomitant treatment with drugs that may interfere with tear gland secretion
-
