Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention type: Silicone Device 2
Intervention description: A silicone tip will be attached to the top of eye drop bottle. Neonatal nursing staff will administer phenylephrine 1% and cyclopentolate 0.2% eye drops to preterm infants to prepare the eye for retinopathy of prematurity eye examinations. One set of eye drops will be administered 30 to 45 min before the eye examination. Up to two more doses can be administered (15 to 20 min apart) if needed, at the request of the ophthalmologist. Administration of eye drops will be recorded to confirm dose administration.

Diagnosis
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation of device will occur off site and by a member of the research team (DR) who is not part of data collection.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Block randomisation will occur by computerised central randomisation. This will occur for ethnicity to ensure four Maori participants are randomised to each group.
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?
