INTRODUCTION: We present a case of persistent aqueous misdirection post Ahmed glaucoma valve despite undergoing an anterior vitrectomy with hyaloido-zonulectomy, and iridectomy. CASE REPORT: A 73 year old female 4 months post phaco-trabeculectomy was referred with persistent high IOP. Post-operatively, she developed aqueous misdirection with a flat anterior chamber (AC) but with an IOP of 15▒mm Hg. On presentation her AC was shallow with peripheral iris-cornea touch and IOP was 39▒mm Hg...

PURPOSE: To describe a case of severe capsule contraction syndrome causing significant astigmatism due to intraocular lens (IOL) folding. METHODS: Case report. RESULTS: Capsule fibrosis and contraction resulted in bending of the hydrophilic IOL along its long axis. Anterior Nd:YAG capsulotomy resolved the situation and restored the patient's visual acuity. CONCLUSIONS: Hydrophilic IOLs are more susceptible to capsule contraction due to the increased flexibility of highly hydrated materials...

EDITORIAL
Mininder S Kocher
Fluid pump management is essential for successful hip arthroscopy. Low pressures can lead to poor visualization. High pressures can lead to fluid extravasation and complications. Fluid extravasation during hip arthroscopy can lead to intra-abdominal compartment syndrome, which can be life-threatening. Risk factors for extravasation included higher pump pressures and iliopsoas tenotomy. By accurately measuring pump pressures, minimizing the necessary pressure, avoiding excessive capsulotomies, performing iliopsoas tenotomy only if needed and performing it at the end of the operation, and monitoring the patient for abdominal distention and hypothermia, complications can be minimized...

In femtosecond laser-assisted cataract surgery, the parameter such as horizontal spot spacing and energy level can be adjusted. Although there have been several studies reported on various laser systems, showing the effects of varying energy levels and horizontal spot spacing on lens capsulotomy cut edges, none have been reported on the Catalys laser system (Abbott Medical Optics, Inc., Santa Ana, CA). The aim of this study is to evaluate, using scanning electron microscopy (SEM), the quality of the cut edges of the laser lens capsulotomy obtained using the Catalys Laser System, using different horizontal spot spacing and energy levels, and to determine the ideal parameters based on SEM results...

PURPOSE: We present a minimally invasive tissue-sparing posterior superior (TSPS) approach that intends to protect the abductor muscles during total hip arthroplasty, prevents the release of the short rotator muscles, and provides the surgeon with the option to repair the posterior capsule. We hypothesized that the TSPS technique would produce a better clinical outcome, faster recovery, and lower complication rates, and that it would not jeopardize acetabular component position. METHODS: A retrospective, observational study was conducted in a consecutive series of patients...

BACKGROUND AND OBJECTIVE: This study sought to evaluate anterior capsulorhexis opening (ACO) reductions after surgery for a subluxated lens. Significant reduction of an ACO supports direct zonular involvement (capsular factors excluded by use of capsular tension rings [CTRs] and modern intraocular lens [IOLs]), and these findings question the long-term efficacy of subluxated lens surgery by means of cataract surgery. A small ACO due to lens mobility, non-enlargement of the ACO, and no lens epithelial cell washing due to an additional risk of further zonular damage were left as additional features to evaluate the possible outcomes of this simplified but still complicated surgery...

Purpose: Femtosecond laser-assisted cataract surgery (FLACS) is an increasingly common procedure. Most laser systems require corneal applanation and thereby increase intraocular pressure (IOP). The purpose of the present study was to evaluate the IOP changes that occur during the FLACS procedure performed using the Catalys femtosecond laser system. Methods: IOP was measured by direct cannulation of the vitreous body of porcine cadaver eyes (N = 20). By inserting a second cannula connected to a water column, all the eyes were set to a baseline IOP of 20 mm Hg...

Despite the appeal of an automated method of creating a perfectly circular anterior capsulotomy, global adoption of femtosecond laser capsulotomy (FSLC) has been limited by its high acquisition and per case cost. In addition, the femtosecond laser's large size and the need for eye docking create surgical efficiency and workflow challenges. The Zepto precision pulse capsulotomy (PPC) technology creates a circular anterior capsulotomy of a precise diameter using a disposable handpiece and tip that are used in the normal surgical sequence...

Christopher C Teng
The Argentinean Flag Sign is a complication that occurs during capsulorhexis construction, in which the capsulorhexis extends to the periphery due to lens intumescence. Phaco capsulotomy is a technique in which the phacoemulsification tip is used to simultaneously create the initial tear in the anterior capsule and remove a portion of the intumescent lens, thereby debulking and relieving pressure from the lens and capsule, and preventing the Argentinean Flag Sign. A detailed description of the phaco capsulotomy technique is provided, including applications and potential complications...

A young patient underwent phacoemulsification with endocapsular implantation of trifocal toric lens in both eyes (AT LISA tri toric 939 MP, Carl-Zeiss, Germany). One-week postsurgery, he developed capsular block syndrome (CBS) in both eyes. There was deterioration of uncorrected visual acuity at 1-week postsurgery, with a myopic shift of 2.5 diopters (D) in the right eye and 2.0 D in the left eye. The intraocular pressure was only elevated in the left eye. Neodymium: yttrium-aluminum-garnet laser posterior capsulotomy resolved the block successfully in both eyes...
