PURPOSE: Unpreserved phenylephrine is often used as an off-licence intracameral surgical adjunct during cataract surgery to assist with pupil dilation and/or stabilise the iris in floppy iris syndrome. It can be delivered as a neat 0.2 ml bolus of either 2.5 or 10% strength, or in a range of ad-hoc dilutions. We wished to assess the accuracy of intracameral phenylephrine preparation in clinical practice. METHODS: Phenylephrine 0.2 ml was analysed both neat (2...

Background: Intraoperative Floppy Iris Syndrome (IFIS) is an important cause of surgical complications and iris defects in patients undergoing phacoemulsification that were treated with selective subtype α1A receptor antagonists for a long period of time. To date, no definitive preventive strategy has emerged, yet. The need of prophylaxis is dictated by the high prevalence of males affected by benign prostatic hyperplasia undergoing cataract surgery. Objective: To identify the best prophylactic strategy in groups at risk of IFIS development by comparing two mydriatic treatments in course of phacoemulsification surgery...

Introduction: The use of alpha-1 receptor antagonists in the treatment of benign prostatic hyperplasia (BPH) has created a problem in ophthalmic surgery, the so-called intraoperative floppy iris syndrome (IFIS). This consists of a billowing iris, insufficient pupillary dilation with progressive intraoperative miosis, and protrusion of iris tissue through the tunnel and side port incision that are made for access to the anterior chamber during surgery. IFIS presents particular difficulties in cataract surgery which is carried out through the pupil with manipulations in the immediate vicinity of the iris...

PURPOSE: The aim of this study was to evaluate the efficacy and safety of topical atropine and topical atropine combined with intracameral low-concentration, bisulphite-containing epinephrine treatment for the prophylaxis of intraoperative floppy iris syndrome. MATERIALS AND METHODS: Seventy-two eyes of 55 male patients who were treated with alpha-adrenergic antagonist medications for benign prostatic hyperplasia were included in this study. Standard premedication with topical cyclopentolate, phenylephrine, tropicamide and ketorolac was applied to all of the patients...

PURPOSE: To evaluate the incidence of and factors associated with intraoperative floppy iris syndrome (IFIS) in patients undergoing cataract phacoemulsification. METHODS: In total, 319 eyes of 319 patients who underwent phacoemulsification with implantation of an intraocular lens (IOL) into the posterior chamber were included in this study. Direct injection of epinephrine into the anterior chamber was performed in all cases. The following patient information was collected: gender, age, axial length of the eye, presence of pseudoexfoliation syndrome, glaucoma, diabetes mellitus, hypertension, current use of medications including alpha1 adrenergic receptor antagonists (alpha1-ARAs), finasteride, and benzodiazepines, duration of intake of alpha1-ARAs and finasteride, and duration of the surgery...

PURPOSE: To analyze the frequency of inappropriate hospitalization in cataract surgery and the type of related determinants. METHODS: A nested retrospective case-control study was carried out on 2708 consecutive cataract surgery patients operated between January 2013 and December 2015. All cases with inappropriate hospitalization (day surgery or ordinary hospitalization) were compared with a control group of cases treated in an appropriate (day service) regimen...

Purpose: To evaluate the effect of intracameral phenylephrine/ketorolac (1%/0.3%) during cataract surgery on the use of iris fixation ring and surgical time in patients with poor pupil dilation (≤5.0 mm) or intraoperative floppy iris syndrome (IFIS). Setting: Private practice outpatient surgical center. Design: This retrospective analysis was conducted from January 1, 2014 to October 7, 2015. Materials and methods: The use of iris fixation rings was evaluated in a retrospective analysis of 46 patients who underwent cataract surgery from January 1, 2014, to October 7, 2015, and who were identified before surgery to be at risk for intraoperative miosis...

PURPOSE: To compare the effects of alfuzosin hydrochloride and tamsulosin hydrochloride on choroidal thickness (CT) and pupil diameter (PD) sizes in patients with benign prostatic hyperplasia. SUBJECTS AND METHODS: Sixty-three men patients with newly diagnosis of benign prostatic hyperplasia were randomly assigned to either alfuzosin hydrochloride or to tamsulosin hydrochloride groups in this prospective, randomized, parallel-group clinical trial. Enhanced depth imaging spectral-domain optical coherence tomography, pupillography were obtained at baseline, 1st and 3rd month, and choroidal thicknesses and pupil diameter sizes were compared between the two groups...

BACKGROUND: Intracameral Mydrane might facilitate a more streamlined cataract service and improve the patient experience. There is limited 'real-world' evidence of its use in a UK setting. METHODS: As part of a local evaluation of cataract surgery using intracameral Mydrane (group 2; n=60), data were collected on intraoperative pupil size and postoperative visual acuity (VA), as well as the rate of mechanical pupil dilation, intraoperative floppy iris syndrome (IFIS) and complications...

Intraoperative floppy iris syndrome (IFIS) was first described by Chang and Campbell in 2005. The characteristics of this syndrome include: 1. Floppy iris that billows in reaction to intraocular fluid currents during standard phacoemulsification procedure; 2. Flaccid iris stroma that tends to prolapse through well-constructed surgical incisions; 3. Insufficient pupillary mydriasis despite proper pharmacologic preparation and progressive pupillary constriction during the operation. Surgical procedures with IFIS have since been noted to have an exceptionally high rate of complications, some of which can be vision threatening...

According to the World Health Organization, cataract is the major cause of reversible visual impairment in the world. It is present as the cause of decreased visual acuity in 33% of the visual impaired citizens. With the increase of life expectancy in the last decades, the number of patients with cataract is expected to grow for the next 20 years. Nowadays, the only effective treatment for cataracts is surgery and its surgical outcomes have been increasingly satisfactory with the technological advancement...

Purpose. To report a modified surgical strategy in the management of intraoperative floppy iris syndrome-associated iris prolapse. Methods. Prolapsed iris is left as is and a new corneal incision near the original wound but at a different site is created. Depending on the location of the original incision and the surgeon's preference, this additional incision can be used as a new port for phacoemulsification tip or can be the new site for the iris to securely prolapse, allowing for the surgery to proceed safely...

PURPOSE: To evaluate the visual and anatomical outcomes of Descemet stripping automated endothelial keratoplasty (DSAEK) in patients with toxic anterior segment syndrome (TASS). METHODS: Fourteen eyes of 14 patients who underwent clear corneal DSAEK for endothelial decompensation secondary to TASS after phacoemulsification were included in this prospective study. Intraoperative surgical difficulties were noted. Preoperative and postoperative evaluation of visual acuity, slit-lamp examination, intraocular pressure, central corneal thickness, and endothelial count was performed in all cases...

OBJECTIVE: We report 3 cases of intraoperative floppy-iris syndrome (IFIS) during cataract surgery in patients without a history of selective α1-blocker use but with a long-term history of antipsychotic drug use. We reviewed previously reported cases of antipsychotic drug-associated IFIS cases. DESIGN: Observational case series. RESULTS: In case 1, bilateral IFIS developed in a 39-year-old man with chronic angle-closure glaucoma. He had used several classes of antipsychotic drugs to treat schizophrenia, including the first-generation antipsychotic drugs haloperidol and chlorpromazine, the dopamine system stabilizer aripiprazole, the dopamine serotonin antagonists olanzapine and quetiapine, and the serotonin dopamine antagonists risperidone and blonanserin for 7 years...
