Prophylactic Treatment: Lessdrops™ vs Standard Drops Regimen

Cataract surgery is one of the most commonly performed surgeries in the world today. To improve the overall procedure outcome, prophylactic topical antibiotics and anti-inflammatories (steroidal and non-steroidal, NSAID) are frequently used to decrease the risk of postoperative infection (e.g., endophthalmitis) and intraocular inflammation (e.g., macular edema, CME).

Even though, the large body of literature that supports the significance of prophylactic eye drops prior to surgery, patient compliance is a common problem. Different factors have been associated with patient's lack of compliance. It could be due to patient's inability to self- administer the drops, lack of understanding of the importance of using the prophylactic treatment as well as understanding the instructions of how to administer the drops and its storage, or just forgetfulness or the fact that they don't like to put the drops multiple times a day for 2-4 weeks, therefore they just avoid doing it. About 64% of patients adhere to the prescribed treatment.

There is a new alternative that combines the most commonly used antibiotic and anti-inflammatories into a single drop. The use of a single drop compounded ophthalmic solution may offer advantages such as increased compliance, patient comfort and reduced ocular toxicity. T

The purpose of this study is to compare the Pred-Gati-Brom formulation to the standard topical drops regimen that includes the topical use of Gatifloxacin, Bromfenac and Prednisolone acetate 1%.
