Eye Drops Self-instillation Clinical Trial
Official title:
The Effect of "Eye Drop Guide" on the Success Rate of Eye Drops Self-instillation in Glaucoma Patients.
To investigate if the Eye Drop Guide more effective than carefully instructed routine
technique for chronic glaucoma patients to self-instill eye drops.
And what factors are associated with the failure of self-instillation eye drops with the Eye
Drop Guide?
The participants are randomized into 2 groups. For group I; the participants will be
instructed to use the Eye Drop Guide first while for group II; the participants will be
instructed to use the routine self-instillation technique first. The instruction will be
given to all participants by the same investigator. The participants are allowed to practice
until confidence in the techniques to which they are assigned. The participants then are
instructed to use only that technique to instill eye drops in both eyes every day and keep
the diary to document the date, time of practice, and number of bottles use in each eye for
practice at home. The investigators make a telephone visit at 1 week to remind the practice
routine and the follow up schedule. The 2 week follow up will be scheduled to evaluate the
self-instillation performance using the techniques to which they are assigned by the VDO
recordings under the same setting as Day 1.
After VDO recordings the participants will be switched to receive the other technique with
the same instruction as the other group. Allow the same period of practice in the hospital
and at home. The investigators again will make a 1-week telephone visit and 2-week follow up
after self-practice at home. At week 4 the VDO recordings of self-instillation performance
will be taken again under the same setting as previous records.
