Background: The present study sought to observe the effect of retaining intact posterior capsule in congenital cataract surgery in children aged 4-8 years.
Methods: This is a retrospective case control study. Seventy-seven children (130 eyes) aged from 4 to 8 years who underwent cataract surgery were divided into two groups. In Group A, 50 eyes underwent phacoemulsification, intraocular lens implantation and posterior capsule capsulotomy combined with anterior vitrectomy. In Group B, 80 eyes underwent cataract phacoemulsification and intraocular lens implantation. The postoperative visual acuity and the rate of complications were compared.
Results: In all patients, cataract surgeries were performed evenly without intraoperative complications. The follow-up time ranged from 6 months to 42 months. No apparent visual axis opacity was detected in group A during the follow-up. By the last visit, apparent visual axis opacity was detected in 31 eyes (38.75%) in group B. Among them, 9 eyes (29.03%) with mild posterior capsule opacification (PCO) were treated with Nd:YAG laser, 3 eyes (9.68%) with thick proliferative membranes were treated with posterior capsule capsulotomy combined with anterior vitrectomy and proliferative membranes in 19 eyes (61.29%) were completely aspired and the posterior capsule was retained. During follow-up, only 2 (6.45%) eyes had PCO recurrence and were treated with Nd:YAG laser. The visual acuity was significantly higher than that before surgery in all patients.
Conclusions: For older children, the incidence of PCO will be low even if intact posterior capsule is retained. Either Nd:YAG laser or surgical treatment for PCO will be able to maintain good vision.

Hydroxypropyl methylcellulose remove dense water droplets during fluid-air exchange on the posterior surface of intraocular lenses with posterior capsule loss.

Department of Ophthalmology, the First Affiliated Hospital of Zhengzhou University, Zhengzhou, Henan, China.
Purpose: The research investigates the efficacy of hydroxypropyl methylcellulose (HPMC) treatment in facilitating the development of compact water droplets on the rear surface of synthetic lenses with capsule imperfections during the process of fluid-air exchange.
Method: This study examined four patients with intraocular lens (IOL) implants and posterior capsule defects who experienced the formation of dense water droplets on the posterior surface following fluid-air exchange. When this occurrence obstructs fundus visualization during surgery, it is recommended to suspend the surgical procedure.
Cerebral white matter damage in patients with end-stage kidney disease associates with cognitive impairment.

Background: Damage to brain white matter often occurs in individuals with chronic kidney disease, which might be related to their cognitive decline. This study aims to investigate tract-specific white matter damage in patients with end-stage kidney disease by using fixel-based analysis.
Methods: Images of 31 end-stage kidney disease patients and 16 normal controls (aged: 61.

This study aims to analyze the prevalence and severity of posterior capsule opacification (PCO) and glistening in a new hydrophobic biaspheric monofocal intraocular lens (IOLs) 24 months after implantation. By means of a ambispective, observational, case-control design, a total of 297 eyes from 200 cataract surgery patients were included in the study (118 females and 82 males; mean age: 72.31 ± 9.

Background: There are differences in the extent of excision of articular processes, spinal processes and posterior ligamentum complexes (PLC) for posterior approach lumbar interbody fusion. Given that the biomechanical significance of these structures has been verified and that deterioration of the biomechanical environment is the main trigger for complications in both fused and adjacent motion segments, changes in decompression ranges may affect the potential risk of adjacent segmental disease (ASD) biomechanically; however, this topic has yet to be identified.
Methods: Posterior lumbar interbody fusion (PLIF) with different decompression strategies was simulated in a well-validated lumbosacral model.
Remplissage Using Percutaneous Needle Navigation With Knotless Anchors in a Suture Staple Configuration.

Remplissage is a procedure that decreases the rate of recurrent instability after arthroscopic stabilization in patients with an engaging Hill-Sachs lesion. This technique involves capsulotenodesis of the infraspinatus tendon and posterior capsule into the Hill-Sachs lesion using 2 knotless anchors with suture passage through the infraspinatus tendon guided by a percutaneous needle. Previously described techniques use knots or anchor placement through the infraspinatus, which can be challenging to control and irreversible if tendon penetration occurs in an undesirable location.
