Brief summary
The purpose of this study is to evaluate efficacy and safety of the ophthalmic solution PRO-155 in patients post phacoemulsification.
Detailed description
Postsurgical inflammation is an inevitable condition after cataract surgery. The use of non-steroidal anti-inflammatory drugs is a safe option for treating ocular inflammation. This is a phase II randomized double-blind clinical trial. The aim is to compare and to evaluate efficacy and safety of two ophthalmic solutions in patients post phacoemulsification. Patients will be randomized to receive either PRO-155 or Nevanac for 60 days.
