Purpose: It is commonly accepted that phacoemulsification surgery is a risk factor for the development of posterior vitreous detachment (PVD) and may accelerate the process. This is an important consideration particularly in cases involving young patients who pre-operatively have no PVD, given the increased risk of retinal tears and detachments.
Methods: A comprehensive literature search was conducted to identify studies reporting incidence of PVD post-uncomplicated phacoemulsification surgery. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement was used for search strategy. Of 3071 titles, 7 studies met the inclusion criteria; The outcomes measured were PVD occurrence by (1) time, (2) type, (3) age, (4) gender and (5) axial length, with all statistical analysis performed using Review Manager.
Results: A total of 2034 eyes were included for analysis with a mean follow-up time of 28.3 months. 33.3% of patients developed a PVD, either partial or complete, with rates increasing in a time dependent manner. No significant difference was noted in sub-group analysis by age, gender or axial length.
Conclusions: The results from our systematic review show that uncomplicated phacoemulsification accelerates the physiological process of PVD development. Pre-operative evaluation of the vitreoretinal interface should be performed with careful post-operative follow-up advised in those without a pre-existing PVD.

Prospective study on the role of preoperative mannitol in capsulorhexis and reducing intraoperative complications in primary angle-closure disease surgery.
J Int Med Res
January 2025
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.
Clin Ophthalmol
January 2025
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.

Rocky Vista University, Englewood, CO, USA.
Introduction: This retrospective, consecutive, real-world case series assessed the efficacy and safety of third-generation trabecular micro-bypass stent implantation (iStent infinite) with phacoemulsification in patients with mild-to-moderate primary open-angle glaucoma (POAG).
Methods: Patients underwent phacoemulsification combined with implantation of iStent infinite (containing three stents) by a single U.S.
Impact of central corneal astigmatism on postoperative visual outcomes in patients undergoing trifocal intraocular lens implantation.
BMC Ophthalmol

Department of Ophthalmology, Eye & ENT Hospital, Fudan University, 83 Fenyang Road, Xuhui District, Shanghai, 200031, China.
Background: To investigate the impact of central corneal astigmatism on postoperative visual outcomes in patients with trifocal intraocular lens (IOL) implantation.
Methods: This retrospective study included 278 eyes of 278 patients who underwent uneventful cataract surgery with implantation of the trifocal IOL (AT LISA tri 839MP). Patients were divided into two groups according to the total corneal refractive power (TCRP) in 3 mm zone centered on the corneal apex: low astigmatism group, TCRP ≤ 0.

Department of Ophthalmology, Dünyagöz Tunus Hospital, Ankara, Türkiye.
Clinical Relevance: Pseudoexfoliation syndrome (PXS) is a common age-related disorder associated with glaucoma and cataract. Despite its clinical importance, the pathogenesis of PXS is not yet fully understood.
Background: To evaluate levels of SCUBE-1 (signal peptide, CUB domain, and epidermal growth factor-like domain containing protein 1) in the serum and aqueous humour of patients with PXS in comparison with non-PXS controls.
