12/7/2023 0 Comments Vitreoretinal surgeonsPatients whose records showed incomplete data were excluded. Eyes with a history of ocular diseases that could cause cataract formation or progression, including corneal disease, glaucoma, uveitis, endophthalmitis, optic nerve disease, and blunt or penetrating trauma, and eyes that had multiple intraocular procedures other than SO removal were also excluded. Eyes that underwent phacovitrectomy were excluded. Patients aged 18y or older with prior PPV who underwent phacoemulsification and IOL implantation in the hospital were included. The primary aim of this study was therefore to identify the associations between vitreoretinal surgeons' experience and the time interval from PPV to CE.Īll patients who underwent CE at Zhongshan Ophthalmic Center, Guangzhou, China from Januto Jwere enrolled in an electronic medical record system. A previous study found that post-vitrectomy cataract progression is not associated with surgeons' experience, but the study was limited by its sample size, and no further studies have been conducted. However, any association between vitreoretinal surgeons' experience and the time interval from PPV to CE has rarely been reported. The cataract surgeon's grade and annual case volume are related to better visual acuity outcomes and a lower complication rate. The time interval from PPV to CE is determined largely by the speed of progression of cataract after vitrectomy, with more rapid progression indicating shorter time intervals. The exact cause of cataract development after PPV remains unclear some predisposing factors have been proposed, such as patients' age –, the use of silicone oil (SO) or intravitreal gas –, lens injury during PPV, the complexity of vitreoretinal disease, diabetic retinopathy, , and duration of surgery. Patients with vitreoretinal diseases are generally young, and the eye is unable to accommodate after cataract extraction (CE), which brings many inconveniences to life and work, and increases the health-care costs and financial burden to families and societies. Phacoemulsification with intraocular lens (IOL) implantation is the most common treatment for cataracts, but there are many surgical challenges in vitrectomized eyes. Cataract formation is a frequent late postoperative complication, with up to 80% – of cases developing cataracts within 2y and of these almost 100% – developing nuclear sclerotic cataract. With the continuous evolution of instrumentation and techniques, pars-plana vitrectomy (PPV) has been extensively applied in the treatment of vitreoretinal disorders.
