Objective: To compare the incidence of falls between patients with visually significant cataracts in both eyes and those who have undergone first-eye cataract surgery.

Methods: This retrospective case-control study involved patients with a history of cataracts in both eyes who had undergone first-eye cataract surgery within the past 9 to 12 months (pseudophakic group). The control group comprised patients with cataracts in both eyes (cataract group).

Unplanned Reoperation following Vitreoretinal Surgery.

Purpose: To evaluate the incidence of unplanned return to the operating room following vitreoretinal surgery and assess the reasons.

Methods: In this retrospective case series, medical records of all patients who underwent vitreoretinal surgery were reviewed to determine the incidence and reasons of early (<30 days postoperatively) and late (≥30 days postoperatively) unplanned reoperations after the surgery.
