Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The egegibility was assessed by the investigator. The allocation of patients to numbered containers occurred in sequential order of presentation. The patient was kept blinded to the treatment received, but the containers of the two treatments were physically different.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)

Summary
Brief summary
Controlled open label randomized monocenter clinical study designed to evaluate, in patients suffering from moderate dry eye syndrome, subjective and objective safety and efficacy parameters during and after three months of treatment (4 drops per day) with arabinogalactan 5% w/v solution or hyaluronic acid 0.2% w/v solution . Hyaluronic acid is a widely used tear substitute prescribed for the same indication. Arabinogalactan is a new class 1 medical device according to the European rules.
