Purpose. To evaluate efficacy and safety of primary vitrectorhexis for posterior capsulotomy in highly myopic patients undergoing refractive lens exchange. Methods. The study is a prospective nonrandomized interventional study. The study comprised 60 eyes of 60 myopic patients. All patients underwent refractive lens exchange (RLE) and foldable IOL implantation combined with primary posterior capsulotomy. We used a 23-gauge vitrectomy probe for the creation of the posterior capsule opening. We followed the patients for one year...

AIM: To investigate the kinematics of the scaphoid while the wrist was in radioulnar motion using gated four-dimensional computed tomography (4DCT) imaging. MATERIALS AND METHODS: Six cadaveric wrist specimens were scanned in the following order of capsulotomy and ligament sectioning: (1) ligaments intact, (2) capsulotomy, (3) scapholunate ligament division, and lastly, (4) lunotriquetral ligament division. A three-dimensional model was then reconstructed to analyse the translation and angular displacements of the scaphoid...

BACKGROUND: Osteochondral defects of the radiocarpal, metacarpophalangeal (MCP), and proximal interphalangeal (PIP) joints often necessitate joint arthrodesis or mechanical arthroplasty, which has a limited lifespan. In severely arthritic wrist and finger joints, we propose a novel adjunct for joint salvage using cadaveric meniscus for joint resurfacing as an off-the-shelf alternative to address osteochondral defects and restore normal intraarticular contact stress. METHODS: A total of 14 patients with osteochondral defects in 5 radiocapitate, 5 MCP, 3 PIP, and 1 carpometacarpal joints received cadaveric meniscus to facilitate arthroplasty...

Advances in technology have made surgery in children safer and faster. The management of pediatric cataract has made rapid progress in the past decade with the availability of safer anesthesia, newer technique's, more predictable intraocular lens (IOL) power calculation, a better understanding of neurobiology, genetics, amblyopia management, improved IOL designs for preventing visual axis opacification, and adjuvant postoperative care. Modern vitrectomy machines with minimally invasive instruments, radiofrequency, diathermy, and plasma blades help immensely in complicated cases...

PURPOSE: To evaluate performance of different intraocular lenses (IOLs) after cataract surgery in children aged less than 2 years with regards to rates of visual axis opacification (VAO). METHODS: This was a retrospective chart review of children <2 years of age undergoing cataract surgery with primary posterior capsulotomy, anterior vitrectomy, and IOL over a period of 5 years with minimum follow-up of 1 year at a tertiary care institute. Children with microphthalmos, persistent fetal vasculature, traumatic cataract, aphakia, secondary IOLs, or any other coexisting ocular disease were excluded...

The elbow joint is highly susceptible to joint contracture, and treating elbow contracture is a challenging clinical problem. Previously, we established an animal model to study elbow contracture that exhibited features similar to the human condition including persistent decreased range of motion (ROM) in flexion-extension and increased capsule thickness/adhesions. The objective of this study was to mechanically quantify pronation-supination in different injury models to determine if significant differences compared to control or contralateral persist long-term in our animal elbow contracture model...

Objective: To assess the effect of femtosecond laser-assisted anterior capsulotomy in intumescent white cataract surgery. Methods: Retrospective case series study. One hundred and fifty cataract patients (150 eyes) from June 2014 to June 2015 in Wuhan Aier ophthalmology hospital were enrolled in this study. They were divided into three groups: 50 intumescent white cataract patients (50 eyes) in the study group were performed femtosecond laser-assisted capsulotomy (LenSx system) operation selectively. Fifty intumescent white cataract patients (50 eyes) underwent normal manual continuous circular capsulorhexis as the control group 1...

We describe a technique to prevent late intraocular lens (IOL) subluxation and dislocation that can be associated with progressive zonulopathy. Supracapsular glued IOL fixation is done to retain an intact anterior hyaloid face and avoid vitreous disturbance while providing stable long-term IOL fixation. Phacoemulsification is followed by glued IOL implantation above intact anterior and posterior capsules. Sclerotomies are created ab interno in a supracapsular plane under diametrically opposite lamellar scleral flaps without entering the vitreous cavity...

BACKGROUND: Access to the plantar plate has been described using either a plantar approach or an extensive dorsal approach that required complete joint destabilization and often a metatarsal osteotomy. Clinical scenarios related to plantar plate tear vary and the pathologies in early stages are frequently limited to unilateral soft tissue structures; a less invasive operative approach may be possible. A novel approach requiring a release of only the lateral collateral ligament and the lateral half of the plantar plate is presented in this cadaver model; the extent of joint exposure possible is described...

AIM: To evaluate the surgical treatment and visual outcomes of eyes with cataract and persistent hyperplastic primary vitreous (PHPV). METHODS: This retrospective study included patients with cataract and PHPV treated with various strategies. Anterior PHPV was treated using phacoemulsification with underwater electric coagulation on posterior capsule neovascularization, posterior capsulotomy, anterior vitrectomy, and intraocular lens (IOL) implantation. Posterior PHPV was treated with lensectomy, posterior vitrectomy, retinal photocoagulation, and IOL implantation or silicone oil tamponade...

Hip arthroscopy is promising tool for assessing and treating intra-articular pathologies including labral tears, cartilage injuries, and ligamentum teres tears of the hip. Interportal capsulotomy allows for better visualization and accessibility of the arthroscope and working instruments. The hip capsule has been defined as a crucial stabilizer of the hip joint. Thus, capsular closure is recognized as an important procedure to prevent postoperative instability after hip arthroscopic surgery. Despite the routine capsular closure during hip arthroscopy, there is a small subset of patients who complain of hip pain and dysfunction after surgery most likely because of disruption of hip closure site after routine complete capsular closure with strong suture for treating hip instability...

BACKGROUND: Although acetabular labral repair has been biomechanically validated to improve stability, capsular management of the hip remains a topic of growing interest and controversy. PURPOSE: To biomechanically evaluate the effects of several arthroscopically relevant conditions of the capsule through a robotic, sequential sectioning study. STUDY DESIGN: Controlled laboratory study. METHODS: Ten human cadaveric unilateral hip specimens (mean age, 51...

A 51-year-old woman developed severe fibrosis and occlusion of the visual axis in 1 eye, maintaining a pinhole aperture in the fellow eye, 2 months after uneventful cataract surgery and implantation of a hydrophilic trifocal intraocular lens in the capsular bag. She had not exhibited any risk factor for anterior capsule contraction preoperatively. Femtosecond laser-assisted capsulotomy with a fluid-filled interface system was used to perform a simultaneous anterior capsulotomy in both eyes. Preoperative calculations of the incision depth of the capsulotomy were performed using optical coherence tomography (OCT) and adjusted intraoperatively with the OCT system of the femtosecond laser...
