Purpose: To determine intraoperative complications of cataract surgery over the period 2006 to 2010.
Methods: In this cross-sectional study, 106 of 272 cataract surgical centers in Iran were selected through multistage random cluster sampling from all provinces. In each province, the selected number of centers was proportionate to the number of cataract surgeries, and in each center, the selected number of charts was proportionate to the center's number of cataract surgeries, from which we retrieved intraoperative complications.
Results: The prevalence of intraoperative complications of cataract surgery was 5.04% (95% confidence interval, CI, 3.53-6.54%) in 2006, which decreased significantly to 3.44% (95% CI 1.84-5.04%) in 2010. The most common complication was posterior capsular rupture/vitreous loss which decreased from 4.29% (95% CI 2.93-5.66%) in 2006 to 2.81% (95% CI 1.3-4.31%) in 2010. The next most common complication was suprachoroidal hemorrhage at 0.56% (95% CI 0.25-0.87%) in 2006 and 0.46% (95% CI 0.3-0.62%) in 2010. The least common complication concerned intraocular lens (IOL)-drop. Complications were seen most with lensectomy, while phacoemulsification caused the least complications. Mean hospitalization time in uncomplicated cases was 0.59 days (95% CI 0.58-0.61 days) and in complicated cases 1.14 days (95% CI 1.07-1.20 days; p < 0.001).
Conclusion: Complications of cataract surgery in Iran had a decreasing trend during 2006-2010. However, results from 2010 indicate that cataract surgical complications still need to be focused on. Hospitalization was longer for cases with complications, and further reducing this could help decrease costs of cataract surgery.

Objective: To evaluate the effect of preoperative intravenous mannitol on the capsulorhexis process and intraoperative complications in patients with primary angle-closure glaucoma (PACG).
Methods: In this prospective randomized controlled trial, 65 PACG eyes were randomized into the mannitol and control groups. The capsulorhexis duration, number of forceps grasps, need for viscoelastic re-injection, and intraoperative complications were recorded.

Objective: To assess the visual quality in patients with primary angle-closure glaucoma (PACG) complicated by cataracts after cataract phacoemulsification with intraocular lens (IOL) implantation and goniosynechialysis, and to explore the relationship between pupil size and visual quality.
Methods: A retrospective, non-randomized study was conducted, including 65 PACG patients (75 eyes) who underwent cataract surgery with IOL implantation and goniosynechialysis from July 2021 to June 2023, as well as a control group of cataract-only patients. Visual quality was evaluated using objective and subjective methods at least 3 months postoperatively.

An intraocular lens (IOL) replaces the natural crystalline lens during cataract surgery, and although the vast majority of implants have simple optics, "advanced technology" IOLs have multifocal and extended depth of focus (EDOF) properties. Optical concepts are evaluated here, with image contrast, focal range, and unwanted visual phenomena being the primary concerns. Visual phenomena with earlier bifocal diffractive lenses led to alternative diffractive designs (trifocals, etc.

Myopia is an evolving global health challenge, with estimates suggesting that by 2050 it will affect half of the world's population, becoming the leading cause of irreversible vision loss. Moreover, myopia can lead to various complications, including the earlier onset of cataracts. Given the progressive aging of the population and the increase in life expectancy, this will contribute to a rising demand for cataract surgery, posing an additional challenge for healthcare systems.
