Ocular Surface Tolerability of Prostaglandin Analogs and Prostamides in Patients with Glaucoma or Ocular Hypertension

Introduction There has been increased attention on the potential impact of the preservative benzalkonium chloride (BAK) on the ocular surface. This study compared the ocular surface tolerability of once-daily bimatoprost 0.01% and latanoprost 0.005% (both preserved with 0.02% BAK), and travoprost 0.004% preserved with sofZia™.
