Brand Name Travoprost First, Then Generic
Patients will be randomized to start with brand name travoprost. After 3 weeks, the intraocular pressure will be measured and a crossover will happen. A switch will be made to generic Travoprost. At 6 weeks, the intraocular pressure will be measured. Questionnaires on the comfort and intolerances of the drops will be administered at the visits of 3 and 6 weeks.

SECONDARY outcome

Timeframe: After 3 weeks of either the brand name or generic travoprost

Population: There were 70 patients that were analyzed overall and 70 patients in each arm. This is because this was a cross-over study therefore each patient was part of both arms.

Patients will be asked about: 1. Difficulties related to administration of the drops 2. Compliance to the drops 3. Side effects such as foreign body sensation, blurry vision, conjunctival redness, dry eyes, teary eyes, eye pain, eye pruritis, and a peri-ocular rash
