PURPOSE To determine the role of cavitational energy as a mechanism responsible for the emulsification of the lens during phacoemulsification. SETTING Clinica Ophthalmologica Pasteur, Santiago, Chile. METHODS Cavitation and its relationship to phacoemulsification power were documented using a combination of light sources, high-speed video recording techniques, and computerized control and b...

BACKGROUND/AIM Cataract surgery has become one of the safest procedures in medicine thanks to advances in technology and surgical techniques. Although minimal, we still witness different complications. The aim of this study was to compare visual outcome and complication rate in different techniques of cataract surgery, ie in cataract surgeries with various corneal incision width. METHODS The ...

PURPOSE To elucidate the impact of phacoemulsification on aqueous monocyte chemoattractant protein-1 (MCP-1) levels, and identify its cell origin. METHODS For clinical study, aqueous humor samples were collected before and after surgery (17.0 ± 4.0 months postoperatively) from 21 cataract cases that underwent phacoemulsification and intraocular lens (IOL) implantation. Aqueous MCP-1 levels we...

PURPOSE To evaluate the results of intravitreal phacoemulsification with torsional hand piece in eyes with posteriorly dislocated lens fragments. METHODS In this prospective, interventional case series, 15 eyes with retained lens fragments following phacoemulsification were included. All patients underwent standard three-port pars plana vitrectomy and intravitreal phacoemulsification using sl...

Background: Phacoemulsification surgery is one of the most common surgeries in the world. Various drugs have been used alone or in combination with each other to provide effective and safe sedation in patients, but so far, a drug method agreed upon by anesthesiologists has not been proposed. The purpose of this research was to evaluate the sedative quality of midazolam or propofol with a low do...

BACKGROUND To compare the heat production of 3 different phacoemulsification machines under strict laboratory test conditions. More specifically, the thermal behavior was analyzed between the torsional modality of the Infiniti system and longitudinal modalities of the Abbot WhiteStar Signature Phacoemulsification system and Bausch and Lomb Stellaris system. METHODS Experiments were performed ...

Objective: The objective of this study is to explore the influence of combined femtosecond laser and phacoemulsification on postoperative curative effect and safety on cataract patients. Method: One hundred forty-five cataract patients (148 eyes) needing operation were selected and grouped by difference in operation method: control group, 72 patients (74 eyes) were treated with traditional phac...

• Objective: To apply statistical process control (SPC) techniques to evaluate 3 components of the phacoemulsification cataract surgery procedure. • Design: Retrospective chart review. • Methods: We analyzed 180 cataract surgeries performed by 6 cataract surgeons (3 “high-volume” and 3 “low-volume” surgeons). Surgical parameters evaluated were phacoemulsification time (seconds), phacoemulsifica...

OBJECTIVES To estimate the long-term cumulative incidence of and risk factors for retinal detachment (RD) after phacoemulsification using linked administrative medical data. METHODS We used the Western Australian Data Linkage System to identify patients who underwent phacoemulsification in Western Australia between January 1989 and December 2001. Retinal detachment cases were those patients r...

AIM We conducted this study to evaluate and compare corneal endothelial cell loss between phacoemulsification with continuous anterior chamber infusion using anterior chamber maintainer (ACM) and phacoemulsification using ophthalmic viscosurgical device (OVD). MATERIALS AND METHODS This was a prospective, randomized controlled trial. Fifty eyes of 47 patients of senile cataract undergoing pha...
