Aravind Haripriya, David F Chang, Ravilla D Ravindran
PURPOSE: To compare the postoperative endophthalmitis rate before and after initiation of intracameral (IC) moxifloxacin prophylaxis for both phacoemulsification and sutureless, manual small-incision cataract surgery (M-SICS), as well as in patients with posterior capsular rupture (PCR). DESIGN: Retrospective, clinical registry. PARTICIPANTS: All cataract surgeries (617 453) performed during the 29-month period from January 2014 to May 2016 at the 10 regional Aravind eye hospitals were included...

The most common vision-disrupting complication of cataract surgery is posterior capsule opacification (PCO; secondary cataract). PCO is caused by residual lens cells undergoing one of two very different cell fates: either transdifferentiating into myofibroblasts, or maturing into lens fiber cells. Although TGFβ has been strongly implicated in lens cell fibrosis, the factors responsible for the latter process have not been identified. We show here for the first time that TGFβ can induce purified primary lens epithelial cells within the same culture to undergo differentiation into either lens fiber cells or myofibroblasts...

INTRODUCTION: Fuchs Heterochromic Iridocylitis (FHI) is a rare form of uveitis which is frequently complicated by cataract and glaucoma, but it does not show typical features of uveitis like pain, redness and posterior synechia. AIM: To study the clinical characteristics and outcome of cataract extraction with Intra Ocular Lens (IOL) implantation in patients with FHI. MATERIALS AND METHODS: The present prospective study was carried out in the Postgraduate Department of Ophthalmology, Sher-i-Kashmir Institute of Medical Sciences (SKIMS), Bemina from March 2012 to January 2015...

INTRODUCTION: Posterior Capsular Opacifications (PCO) is a frequent complication of cataract surgery following posterior chamber intraocular lens implantation. Nd -Yag laser capsulotomy is the treatment of choice for PCO and is known to be associated with complications like Raised Intraocular Pressure (IOP), Intraocular lens pitting, intraocular lens cracks, cystoid macular oedema, retinal detachment, corneal burns. Raised IOP is the most common complication and prescribing anti-glaucoma drugs post capsulotomy is a common practise...

BACKGROUND: Cataract and age-related macular degeneration (AMD) are common causes of decreased vision that often occur simultaneously in people over age 50. Although cataract surgery is an effective treatment for cataract-induced visual loss, some clinicians suspect that such an intervention may increase the risk of worsening of underlying AMD and thus have deleterious effects on vision. OBJECTIVES: The objective of this review was to evaluate the effectiveness and safety of cataract surgery compared with no surgery in eyes with AMD...

The early development of lens opacities and lens subluxation are the most common causes of vision loss in patients with anterior megalophthalmos (AM). Cataract surgery in such patients is challenging, however, because of anatomical abnormalities. Intraocular lens dislocation is the most common postoperative complication. Patients with AM also seem to be affected by a type of vitreoretinopathy that predisposes them to retinal detachment. We here present the case of a 36-year-old man with bilateral AM misdiagnosed as simple megalocornea...

PURPOSE: Comparison of resident surgeon performance efficiencies in femtosecond laser-assisted cataract surgery (FLACS) versus conventional phacoemulsification. PATIENTS AND METHODS: A retrospective cohort study was conducted on consecutive patients undergoing phacoemulsification cataract surgery performed by senior ophthalmology residents under the supervision of 1 attending physician during a 9-month period in a large Veterans Affairs medical center. Medical records were reviewed for demographic information, preoperative nucleus grade, femtosecond laser pretreatment, operative procedure times, total operating room times, and surgical complications...

BACKGROUND: Endophthalmitis is a severe inflammation of the anterior or posterior (or both) chambers of the eye that may be sterile or associated with infection. It is a potentially vision-threatening complication of cataract surgery. Prophylactic measures for endophthalmitis are targeted against various sources of infection. OBJECTIVES: To evaluate the effects of perioperative antibiotic prophylaxis for endophthalmitis following cataract surgery compared with no prophylaxis or other form of prophylaxis...

PURPOSE: To review refractive regression and current therapeutic options for patients who have residual refractive error after LASIK. METHODS: An extensive literature search using PubMed was performed for terms such as "LASIK," "PRK," "enhancement," "overcorrection," "undercorrection," "re-lift," "mini-flap," and related terms. RESULTS: The presence of residual refractive error following LASIK is a challenging situation. After excluding anatomical causes (eg, ocular surface disease, cataract, and macular pathology) and intraoperative flap complications, evaluation of the residual stromal bed must be performed...

REVIEW
H Burkhard Dick, Tim Schultz
The use of femtosecond laser surgery improves the precision and reproducibility of corneal incisions and the capsular opening; it also reduces the amount of ultrasound energy required for lens nucleus work-up. The rate of complications reported so far appears to be low. There are a number of contraindications such as a history of cornea and/or glaucoma surgery and certain anatomical features like deep-set eyes, kyphosis, tremor, and obesity. Visual recovery and refractive results of both techniques are excellent...

PURPOSE: To determine the long-term outcomes of 2-site phacoemulsification combined with fornix-based trabeculectomy using mitomycin C (MMC) for primary angle-closure glaucoma (PACG) and primary open-angle glaucoma (POAG) in an Asian population. METHODS: We reviewed the records of all patients with POAG or PACG who underwent phacoemulsification with trabeculectomy using MMC from January 2008 through December 2010 in a tertiary ophthalmology unit in Singapore. The primary outcome measure was cumulative success rates defined as complete [intraocular pressure (IOP) <21, 18, 15 mmHg without medication] and qualified (IOP <21, 18, 15 mmHg with at least 1 medication) success...

Purpose Description and evaluation of the technique and efficacy of canaloplasty ab interno (ABIC) in patients with open angle glaucoma (POAG). Methods In this monocentric series of consecutive cases, patients with cataract and open angle glaucoma (combined operation) and pseudophacic patients (mean age: 78 years, range 66-90 years), and suffering from POAG were included. All of them were operated with ABIC by using the iTrack™ 250 µ-microcatheter (Ellex Medical Lasers Pty Ltd, Adelaide, Australia), in order to circumferentially vasodilate Schlemm's canal without implanting a suture to increase tension...

Purpose Quality control is particularly important in invasive medicine. As cataract surgery is the most frequently performed and most successful ophthalmic surgery, quality control should become mandatory. Patients and Methods Retrospective analysis of all cataract procedures performed in a 12 months period (01. 07. 2014 - 30. 06. 2015) at our hospital, using an internet-based EUREQOU database.

PURPOSE: To compare intraoperative factors and post-operative outcomes of femtosecond laser-assisted cataract surgery (FLACS) and manual cataract surgery performed by resident surgeons. METHODS: All cases of FLACS performed by resident surgeons during the 2013-2014 academic year were compared to a control group of manual cataract surgery cases with regards to pre-operative patient data, operative complications, cumulative dissipated energy (CDE), postoperative corrected distance visual acuity (CDVA), refractive prediction error (RPE), and corneal edema...
