PURPOSE: To evaluate the efficacy and safety of bimanual, low-energy femtosecond laser-assisted cataract surgery with 1.4-mm microincisions compared to standard bimanual phacoemulsification (bimanual microincision cataract surgery). DESIGN: Prospective, non-randomized comparative case series. METHODS: Bimanual femtosecond laser-assisted cataract surgery with microincisions was performed on 80 eyes (Group A) with the low-energy Ziemer LDV Z8; a matched case-control series of 80 eyes performed with standard bimanual microincision cataract surgery technique was selected for comparison (Group B)...

PURPOSE: XEN® gel stent is a minimally invasive surgical device aimed at creating a subconjunctival drainage of aqueous humor, thereby reducing intraocular pressure (IOP). Being a novel device, doubts remain regarding the efficacy and safety of its implantation in the early stage of new users. This paper illustrates the XEN® implantation learning curve, assessed through several surgeons of different expertise. METHODS: Retrospective study on the first 6 XEN® implants performed by each of 10 certified ophthalmic surgeons...

Aim: To conduct a retrospective analysis of secondary IOL implantation in patients who underwent PK with no simultaneous IOL implantation. Materials and Methods: The retrospective study of the secondary implantation of IOLs was conducted in 46 eyes that underwent a primary operation with PK and cataract/lens extraction with no IOL implantation due to capsule rupture or combining corneal or intraocular complications. The minimum period from PK was 12 months. All secondary IOL implantations were performed from January 2011 to August 2017...

We report the rescue effects of adalimumab (HUMIRA® ) therapy in a case of refractory pediatric panuveitis complicated with steroid-induced glaucoma. A 13-year-old girl had suffered from blurred vision since January 2013. Bilateral idiopathic panuveitis with macular edema (ME) was diagnosed. She had previously been treated with systemic steroids, methotrexate, cyclosporine, and mycophenolate. All treatments had failed to suppress the ocular inflammation and ME persisted. Intravitreal dexamethasone implant injections were given to both eyes and ME subsided; however, complications with steroid-induced glaucoma and cataract occurred...

OBJECTIVE: To report the outcomes of cataract surgery performed by non-physician cataract surgeons due to lack of ophthalmologists in remote areas of North Cameroon. DESIGN: Prospective cohort study. SETTING: The main centre of the non-governmental organisation Ophtalmo Sans Frontières in Lagdo. PARTICIPANTS AND INTERVENTIONS: Age-related cataract surgery performed between 28 November 2016 and 17 May 2017. MAIN OUTCOMES MEASURES: The main outcome measure was presenting visual acuity (PVA) 1-4 weeks after surgery, classified according to the WHO as good (PVA ≥6/18), borderline (PVA 6/60-6/18) and poor (PVA <6/60)...

BACKGROUND/AIMS: To report the prevalence of treatable complications (cystoid macular oedema, CME; epiretinal membrane, ERM and cataract) in patients with retinitis pigmentosa (RP). METHODS: Consecutive patients with RP attending a tertiary eye clinic in 2012. Spectral domain-optical coherence tomography was used to determine presence of CME and ERM. Clinic records were reviewed to identify cataract and pseudophakia. Multivariable analyses adjusted for age, gender and other confounders...

Corneal bloodstaining, which is brown or dark yellow in color, is induced by hemoglobin deposition, and its breakdown products extend into the corneal stroma. In this article, we report a rare case of corneal bloodstaining induced by total hyphema after rebleeding for traumatic hyphema. The patient underwent irrigation of the anterior chamber (AC) and cataract surgery of the right eye after trauma. After oral and topical treatment the imprint of corneal bloodstaining faded, and it nearly disappeared after the procedures...

PURPOSE: We aimed to investigate that change of IPI values after sedation of patients undergoing cataract surgery under sedation. METHODS: We included 50 patients (ASA I-III) undergoing cataract surgery under sedation by phacoemulsification method in this prospective observational study. IPI, SpO2 , ETCO2 , respiratory rate (RR), peripheral pulse rate (PR), hemodynamic data and BIS values and perioperative complications were recorded. RESULTS: Compared to baseline values, RR value at 5th min, RR, PR, IPI values at 10th min and RR, PR values at 15th min were significantly low and heart rate value at 15th min and arterial pressure, bispectral index (BIS) values at 5th min, 10th min, 15th min, 20th min, 25th min and 30th min were lower than baseline values...

INTRODUCTION: Vitrectorhexis is an alternative for manual continuous curvilinear capsulorhexis originally developed for paediatric cataract surgery. The aim of our study was the evaluation of the technique in adult patients with penetrating ocular injury and traumatic cataracts. METHODS: Eight eyes of 8 patients (23-41 years, all males) had penetrating mechanical corneal trauma. Anterior lens capsule was penetrated in all cases and additional posterior capsule defect in five cases...

Due to high complexity, vitreoretinal surgery presents a higher number of patient safety incidents compared with other ophthalmic procedures. Intraocular gases are one of the most useful adjuncts to vitrectomy and surprisingly, surgeons commonly admit to having occasional problems with incorrect gas concentration. The aim of this study is to present a consecutive case series of patients with improper concentration of sulfur hexafluoride (SF6 ) applied during vitrectomy. Three patients underwent 27-gauge vitrectomy and at the end of surgery inappropriate dilution of 100% SF6 was administered...

Glycative stress, caused by the accumulation of cytotoxic and irreversibly-formed sugar-derived advanced glycation end-products (AGEs), contributes to morbidity associated with aging, age-related diseases, and metabolic diseases. In this review, we summarize pathways leading to formation of AGEs, largely from sugars and glycolytic intermediates, and discuss detoxification of AGE precursors, including the glyoxalase system and DJ-1/Park7 deglycase. Disease pathogenesis downstream of AGE accumulation can be cell autonomous due to aggregation of glycated proteins and impaired protein function, which occurs in ocular cataracts...

PURPOSE: To report a case that presented with post blunt trauma cataract, zonular dialysis, cyclodialysis and iridodialysis and its successful single-sitting management. METHODS: After lens aspiration, a capsular tension ring and multipiece intraocular lens were placed in the bag to support the zonules, a single eyelet Cionni ring was fixed in the sulcus to provide endocyclotamponade, and iridodialysis repair was done using the 'stroke and dock technique'. RESULT: Successful centration of the intraocular lens, closure of the cleft and apposition of the iris root to its base were achieved at the end of the surgery...
