Quatera 700 vs. Centurion

Phacoemulsification is the most common treatment for cataract surgery in the developed countries and over the years it gained importance due to several factors: small incision, surgery performed under topical anesthesia - which reduce injection-related complications - short recovery time, low post operatory induced astigmatism, and low incidence of surgical complications, when compared to the conventional surgeries. The study evaluates 2 different phacoemulsification devices in patients undergoing routine cataract surgery in both eyes.
