Brimonidine for Subconjunctival Hemorrhage From Femtosecond Laser Assisted Cataract Surgery

Summary

Laser-assisted cataract surgery is a common and precise procedure done to remove cataracts from the eye. This procedure involves putting on a suction cup that applies a mild vacuum seal around the eye to stabilize the eye during the laser procedure. This suction cup often causes some bleeding under the conjunctiva around the eye which takes a few days to disappear. The purpose of this study is to test the use of a well-known eye medication (normally for treating glaucoma) called Brimonidine tartrate 0.15% (or Alphagan-P) in patients having laser-assisted cataract surgery. The use of Brimonidine to reduce bleeding under the conjunctiva is investigational, which means it has not been approved by Health Canada for use outside of research studies like this one. This study will see if Brimonidine will help to reduce bleeding under the conjunctiva in patients having laser-assisted cataract surgery.
