Cataract Surgery<br />

Complications during Cataract Surgery<br />
Cataract surgery is the most commonly performed surgical procedure in ophthalmology, thus representing a significant proportion of the operations<br />
performed at the <strong>Cole</strong> <strong>Eye</strong> <strong>Institute</strong>. From January 2006 through September 2007, a total of 2,412 cataract extraction surgeries were performed. Many<br />
of these surgeries were completed as part of a combined surgical procedure in conjunction with cornea, glaucoma or retinal surgeries, the results of which<br />
are included in those sections of this report. In this section, the results of cataract surgeries performed as a single procedure are described.<br />

Intraoperative complications of cataract surgery were uncommon, occurring in only 2.4 percent of patients. The most common complication was a loss of<br />
lens capsule integrity due to either a rupture of the posterior capsule or zonular dialysis, with or without prolapse of vitreous into the anterior segment.<br />

Postoperative complications were also rare, occurring in 2.2 percent of patients. Cystoid macular edema was the most common complication; it was<br />
