Dry eye can be caused by a variety of iatrogenic interventions. The increasing number of patients looking for eye care or cosmetic procedures involving the eyes, together with a better understanding of the pathophysiological mechanisms of dry eye disease (DED), have led to the need of a specific report about iatrogenic dry eye within the TFOS DEWS II. Topical medications can cause DED due to their allergic, toxic and immuno-inflammatory effects on the ocular surface. Preservatives, such as benzalkonium chloride, may further aggravate DED...

PURPOSE: To compare the accuracy of toric intraocular lens (IOL) alignment using the Verion Image-Guided System versus a conventional manual ink-marking procedure. SETTING: University Eye Clinic Maastricht, Maastricht, the Netherlands. DESIGN: Prospective randomized clinical trial. METHODS: Eyes with regular corneal astigmatism of at least 1.25 diopters (D) that required cataract surgery and toric IOL implantation (Acrysof SN6AT3-T9) were randomly assigned to the image-guided group or the manual-marking group...

Objective: To assess the prevalence, surgical coverage rate and social burden rate of cataract blindness among adults aged ≥60 years in the suburban population of Nantong, Jiangsu, China. Methods: It was a population-based cross-section study. A census with individuals aged ≥60 years was conducted in two villages of the suburb area in Nantong from June to August, 2008. A total of 1 305 individuals received visual acuity and eye examinations. Lens and cataract operative status were evaluated by slit-lamp biomicroscopy...

Endothelial keratoplasty (EK) has revolutionized corneal transplant surgery by providing rapid visual recovery and improved visual outcomes. In parts of the world with Fuchs endothelial dystrophy, many patients may present with both cataracts and corneal degeneration requiring surgery. Other forms of endothelial decompensation may also present with cataracts. The staging or combination of transplant surgery and cataract surgery depend on both the abilities of the surgeon and the surgical techniques being considered...

PURPOSE: To compare the effects of the distance from the inner and outer corneal incision wounds to the corneal apex on the changes in corneal astigmatism after cataract surgery. METHODS: Seventy-two eyes with anterior corneal astigmatism less than 2.50 diopters (D) were evaluated. The distance between the incision wound and the corneal apex was measured using the Pentacam (Oculus Optikgeräte, Wetzlar, Germany) Scheimpflug image and the Image J program (National Institutes of Health, Bethesda, MD)...

INTRODUCTION: Refractive surgery in presbyopia tends to achieve spectacle independence with minimal optical disturbances. We compared monovision to multifocality procedures regarding these outcomes. METHODS: We conducted a systematic review of published (till November 21, 2016) randomized controlled trials (RCTs) comparing any monovision to any multifocality method or comparing different monovision/multifocality methods to each other that enabled direct or indirect comparisons between particular monovision and particular multifocality procedures in presbyopic patients undergoing cataract-related or unrelated surgery in respect to spectacle independence, unaided binocular visual acuity (VA), contrast sensitivity (CS), and adverse events...

A variety of refractive surgery techniques, which reshape the corneal stroma using laser energy, have been marketed as simple and safe alternatives to glasses or contact lenses. Laser-assisted in-situ keratomileusis (LASIK) is the most common of these procedures. Although there are few high-quality prospective studies of long-term outcomes, complications, or stability for refractive surgery procedures, there is at least general agreement that more than 90% of appropriately selected patients achieve excellent uncorrected distance vision...

PURPOSE: To compare changes in intraocular pressure (IOP), axial eye length (AEL), and refractive outcome in primary open-angle glaucoma patients undergoing cataract surgery and trabeculectomy in dependence of the sequence of surgeries. MATERIALS AND METHODS: We retrospectively analysed 48 eyes. The changes in refraction, intraocular pressure, and axial eye length were analysed after surgery. In group A (21 subjects), phacoemulsification was performed before trabeculectomy, and in group B (27 subjects), trabeculectomy was performed before phacoemulsification with a minimum time span between interventions of 6 months...

PURPOSE: To compare the outcomes after toric intraocular lens (tIOL) or peripheral corneal relaxing incisions (PCRI) for keratometric astigmatism (KA) between 0.75 and 2.5 diopters (D) during cataract surgery. DESIGN: Prospective randomized clinical trial. METHODS: Eighty eyes (80 participants) received either tIOL or PCRI and were assessed preoperatively, 1, 3, 6, and 12 months postoperatively. PRIMARY OUTCOME MEASURE: Uncorrected (UCDVA) and best-corrected distance logMAR visual acuity (BCDVA) at 12 months...

PURPOSE: To examine risk factors for low intraocular pressure (IOP) after trabeculectomy and to describe long-term outcomes in these eyes. DESIGN: Retrospective case-control study. PARTICIPANTS: Cases with low IOP included all patients with IOP ≤5 mmHg on 3 or more consecutive visits 3 months or later after trabeculectomy. Control patients without low IOP after trabeculectomy were randomly selected at a 1:2 case-to-control ratio. METHODS: A case-control study was performed of patients undergoing trabeculectomy at the Stein Eye Institute...

A survey was offered to attendees of the 2016 annual meeting of the American Society of Cataract and Refractive Surgery (ASCRS) as well as online to ASCRS members. Of the 429 self-identified surgeons in training or those with fewer than 5 years in practice, 83% had performed complex cataract surgery using iris expansion devices or capsular tension rings (63%) and 70% had implanted a toric intraocular lens (IOL). A minority of respondents had performed laser-assisted cataract surgery (27%) or implanted presbyopia-correcting IOLs (39%), and only half (50%) had performed laser vision correction (LVC)...

Background The collection of pre-, peri- and postoperative data took place between 2005 and 2008, based on a contract between the social insurance company, AOK Mecklenburg-Vorpommern, and the outpatient cataract surgeons/centers in Mecklenburg-Vorpommern, Germany. The purpose of the contract was the monitoring of quality of cataract surgery in the outpatient healthcare system. Materials and Methods We analysed 2952 datasets of 2952 eyes, remaining after exclusion of 109 datasets because of lack of plausibility and missing data (initially 3058 eyes with surgery in our centre)...

PURPOSE: To assess the predictability, efficacy, and safety of posterior chamber phakic implantable collamer lens (ICL) implantation after radial keratotomy. METHODS: In a retrospective non-comparative interventional case series, outcomes in 6 consecutive eyes of 4 patients with residual refraction after radial keratotomy were analyzed after the implantation of ICLs. All of the lenses were implanted to correct the residual refractive error, ranging from -12.00 to +3...

PURPOSE: To determine the postoperative refractive error in eyes with intraocular gas tamponade in combined phacovitrectomy using a Z-haptic intraocular lens (IOL). METHODS: This prospective non-randomized case-control study compared patients with combined phacovitrectomy with or without intraocular gas tamponade to cataract surgery-only. The main outcome measure was the IOL power prediction error (PE). Secondary outcome measures were spherical equivalent, anterior chamber depth (ACD), and axial length...

PURPOSE: Prospective randomised study to compare the impact of phacoemusification (PHACO) and small incision cataract surgery (SICS) on endothelial structure (cell density and morphology) and refractive results (visual acuity, induced astigmatism). METHODS: Prospective study of 57 patients (63 eyes) over 20 months (May 2012-January 2014) undergoing surgery by 2 experienced surgeons. We included patients with senile or presenile cataracts, LOCS III class 2, 3 and 4...

BACKGROUND: Anterior lens opacities (ALO) are found in 3-14% of pediatric patients with cataracts. No clear guidelines exist in the management and treatment of these cataracts. OBJECTIVE: To evaluate pediatric patients with anterior lens opacities and assess rate of amblyopia and need for surgery over time. METHODS: A retrospective chart review was performed on patients with unilateral and bilateral anterior lens opacities (ALOs) seen between January 2008 and December 2014...
