Prospective study on the role of preoperative mannitol in capsulorhexis and reducing intraoperative complications in primary angle-closure disease surgery.
J Int Med Res

Department of Ophthalmology, Peking University People's Hospital; Eye Diseases and Optometry Institute; Beijing Key Laboratory of Diagnosis and Therapy of Retinal and Choroid Diseases; College of Optometry, Peking University Health Science Center. Address: No. 11 Xizhimen South Street, Xicheng District, Beijing, China.
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.
Study on Visual Quality After Cataract Surgery and Goniosynechialysis in Patients with Primary Angle-Closure Glaucoma and Cataracts.

Department of Ophthalmology, Affiliated Hospital of North Sichuan Medical College, Nanchong, Sichuan Province, 637000, People's Republic of China.
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.
