Common Complications in Cataract Surgery: Prevention and Expert Analysis

Cataract surgery is one of the most commonly performed and successful surgical procedures in medicine. However, like all surgical interventions, it carries inherent risks and potential complications. Understanding these complications, their prevention, and appropriate management is essential for both clinical practice and medico-legal analysis.

Most Common Intraoperative Complications

Posterior Capsule Rupture

Posterior capsule rupture occurs in approximately 1-2% of routine cataract surgeries, though rates may be higher in complex cases. This complication can lead to vitreous loss, retained lens material, and increased risk of postoperative complications including cystoid macular edema and retinal detachment.

Prevention strategies include proper patient selection, recognition of risk factors (dense cataracts, pseudoexfoliation, small pupils), and meticulous surgical technique. When rupture occurs, appropriate management includes controlled vitrectomy, proper lens placement or modification of surgical plan, and enhanced postoperative monitoring.

Zonular Dehiscence

Weakness or breakage of the zonular fibers supporting the lens capsule can occur due to trauma, pseudoexfoliation syndrome, or other conditions. Recognition of zonular instability during preoperative examination and early intraoperative detection are critical for safe completion of surgery.
