: Advances in technology and technique have led to a significant improvement in the prognosis after cataract surgery. However, there are complications that can significantly affect this prognosis, such as posterior capsule rupture and corneal decompensation. For vitreous prolapse associated with posterior capsule rupture, classic or pars plana anterior vitrectomy is required. : The aim of the study was to compare corneal endothelial cell destruction after cataract surgery associated with posterior capsule rupture and classical and pars plana anterior vitrectomy, respectively. : The study was prospective, on 12 consecutive cases of cataract surgery associated with posterior capsule rupture. Classical anterior vitrectomy was performed in group A, with 5 patients, while pars plana anterior vitrectomy was performed in group B. For all cases, the Stellaris phacoemulsification device (Baush & Lomb, tm) and the associated vitrectomy device was used. : Pars plana anterior vitrectomy had a statistically significant lower rate of corneal endothelial damage, both in absolute value and as a percentage of initial density. : Pars plana anterior surgery is a somewhat unfamiliar technique for anterior pole surgeons. But it is easy to learn and brings a decrease in the rate of damage to the corneal endothelium.

Unlabelled: The scientific and practical interest in studying the biomechanical characteristics of the lens capsule, on the one hand, is associated with its anatomical significance in modern microinvasive phaco surgery, and on the other hand, with investigation of the mechanisms of lens curvature changes during accommodation. Selective study of the biomechanical properties of the lens capsule aims to identify characteristics of various regions and surfaces of the capsule.
Purpose: This study is a comparative analysis of age-related changes in the biomechanical properties of the anterior (AC) and posterior (PC) lens capsules in humans.

Background And Aim: Osteoid osteoma (Oo) and osteoblastoma (Ob) are rare primary bone tumors with a higher prevalence in the second decade of life. Treatment can be conservative, but in cases of spinal location, resective surgery is of great importance but may be challenging.
Material And Methods: We report four pediatric cases of Oo and Ob managed in our unit, with different locations at the level of the cervical spine.

Purpose: To study the utility of integrated intraoperative OCT (i2OCT) in pediatric patients with cataracts in the real world.
Methods: It was a retrospective case series. We included patients aged 0-12 years with unilateral or bilateral cataracts who underwent cataract surgery or membranectomy for visual axis opacification between July 2022 and December 2023, where intraoperative OCT was used.

Purpose: To study change in the contact of intraocular lens (IOL) with the posterior capsule with respect to the vertical versus horizontal orientation of the haptic-optic junction of the IOL using intraoperative spectral domain optical coherence tomography (SD-OCT).
Methods: Fifty eyes of 50 patients with senile immature cataract underwent topical phacoemulsification procedure with implantation of a monofocal IOL by a single experienced surgeon. The Rescan 700 SD-OCT system was used for intraoperative imaging.

Intraocular lenses (IOLs) play a pivotal role in restoring vision following cataract surgery. The evolution of polymeric biomaterials has been central to addressing challenges such as biocompatibility, optical clarity, mechanical stability, and resistance to opacification. This review explores essential requirements for IOL biomaterials, emphasizing their ability to mitigate complications like posterior capsule opacification (PCO) and dysphotopsias while maintaining long-term durability and visual quality.
