Official Title: Randomized, Controlled Trial in Patients With Senile Cataract to Evaluate the Efficacy of Ultrasound-free Femtosecond Laser (FLACS) Cataract Surgery (USFREE), Compared to Traditional Phacoemulsificati
Brief Summary: Despite the advantages already demonstrated by FLACS, these surgeries still require ultrasonic devices for fragmentation of the lens. The ultrasonic energy used during phacoemulsification may induce complications such as reduction of endothelial cells and corneal edema. In this sense, it would be beneficial to develop surgical techniques that eliminate the need for ultrasound. The group of surgeons of Alfredo Tranjan Ophthalmic Center, recently developed a surgical technique of cataract that optimizes the use of the laser, eliminating the need for ultrasound during the surgical procedure. Thus, the crystalline fragmentation process does not involve ultrasound being performed by the laser itself. It is expected that this procedure will reduce the complexity of cataract surgery, and be safer in terms of potential corneal lesions. The present study intends to evaluate the benefit and safety of FLACS without use of ultrasound (USFREE), compared to traditional phacoemulsification surgery using ultrasound in patients with senile cataract. In this sense, it is intended to primarily compare the volume of balanced saline solution (BSS) between surgeries.
