Dislocated Lens, Needle, Pars Plana Vitrectomy, Phacoemulsification
Conditions
Brief summary
The goal of this observational study is to learn about the effects of 25-gauge (G) needle-assisted phacoemulsification to remove dislocated intravitreal lens nuclei.
Detailed description
Patients with dislocated intravitreal lens nuclei who underwent 23G pars plana vitrectomy (PPV) and 25G needle-assisted phacoemulsification between July 2022 and September 2024 were included. Primary outcomes included best-corrected visual acuity (BCVA) and intraocular pressure (IOP). Secondary outcomes included corneal endothelial cell count (CECC) and the incidence of intraoperative and postoperative complications. These outcomes were statistically analyzed both preoperatively and postoperatively. A minimum follow-up of 6 months was completed for all eyes.
