Study summary

The goal of this randomized, active-controlled, parallel-group trial is to evaluate the clinical efficacy of amniotic membrane extract eye drops (AMEED) in reducing signs and symptoms of hyposecretory dry eye

Participants will receibed amniotic membrane extract eye drops 6 times daily and was evaluated at baseline day and day 30th.

Researchers will compare against autologous serum eye drops effects

Read the detailed description

This was a randomized, active-controlled, parallel-group trial. The perfect masked conditions could not be accomplished because the autologous serum eye drops needs venous punction for it preparation.

During de initial 2 weeks screening period, the patients received artificial tears 4 times daily to minimize the effects of any eye drops used before patients were allocated randomly to receive autologous serum eye drops (ASED) or AMEED, administered as 1 drop in each eye 6 times daily, respectively, for 30 days.
