Tamar Pedut Kloizman, Raneen Shehadeh Mashour
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...

BACKGROUND: We aimed to report a simple technique that involves modified anterior (to the limbus) elongated corneal incisions in order to reduce the incidence and severity of intraoperative floppy iris syndrome (IFIS) and related complications. METHODS: This was a retrospective study of phacoemulsification cataract surgeries performed by a single surgeon on patients receiving tamsulosin or alfuzosin between 1 January 2009 and 31 July 2012 at Meir Medical Center, Kfar-Sava, Israel...

AIM: The purpose of this study was to investigate intraoperative iris behavior during some phacoemulsification maneuvers in rabbits treated with tamsulosin or finasteride. MATERIAL AND METHOD: An experimental study was conducted on 26 Metis male rabbits aged 1.5 - 2 years, body weight between 3.4 and 5.6 kg, divided into three groups: Group 1 - Control, 6 rabbits; Group 2 - tamsulosin, 10 rabbits; Group 3 - finasteride, 10 rabbits. Dose calculation was performed according to body surface area ratio man/rabbit, taking into account the median lethal dose LD50...

OBJECTIVE: Intracameral mydriatics using epinephrine associated with lidocaine have been reported as efficacious in reducing intraoperative floppy iris syndrome (IFIS) complications during cataract surgery. The aim of this study was to verify the efficacy of intracameral epinephrine without intracameral lidocaine as prophylaxis against IFIS in patients on tamsulosin. MATERIALS AND METHODS: This was a retrospective study on the results of cataract surgery in 18 patients on therapy with tamsulosin...

CASE REPORT: The case is presented of a severe Intraoperative Floppy Iris Syndrome (IFIS) in a patient that had been treated with duloxetine. DISCUSSION: Tamsulosin is the main etiological agent involved in IFIS. However several cases of IFIS, supposedly secondary to drugs of different groups have recently been reported in the literature. The authors use this case report as a means to discuss why most of these cases should be considered anecdotal evidence.

PURPOSE: The α₁A-adrenoceptor (α₁A-AR) subtype was suggested to mediate contraction and trophic effects in the iris dilator muscle, and thus its pharmacological blockade may be involved in intraoperative floppy iris syndrome. We tested the hypothesis that the α₁A-AR mediates pupil dilation and trophic effects in the mouse iris. METHODS: The α₁-AR subtype mRNA expression was quantified in iris tissue by real-time PCR. To assess the role of individual α₁-ARs for mediating pupil dilation, the α₁-AR agonist phenylephrine was topically applied to the ocular surface of mice deficient in one of the three α₁-AR subtypes (α₁A-AR(-/-), α₁B-AR(-/-), α₁D-AR(-/-), respectively) and wild-type controls...

Small pupil and Intraoperative Floppy Iris Syndrome (lFIS) has always been a challenge in cataract surgery. Iris dilation and mechanical stabilization can be achieved by using intraoperative iris retractors, preferably before capsulorhexis. Malyugin ring is a mechanical iris expansion device, which presents many advantages (gently relaxes the iris tissue, implants easier and less traumatic). The disadvantages of using Malyugin ring consists primarily in the high cost and in an increased duration of surgical procedure...

PURPOSE: The purpose of this study was to evaluate the incidence, risk factors, and impact of intraoperative floppy iris syndrome (IFIS) on surgical performance. MATERIALS AND METHODS: Consecutive cataract surgeries from October 2010 to Feb 2011 (1003 eyes, 980 patients; 568 males, 412 females) were analyzed prospectively. Operating surgeon, masked about medication history, noted the intraoperative details. Cases were identified as IFIS or non-IFIS. Multivariate analysis was performed to find risk factors for IFIS...

INTRODUCTION: Naftopidil, approved initially in Japan, is an α1d-adrenergic receptor antagonist (α1-blocker) used to treat lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH). It is different from tamsulosin hydrochloride and silodosin, in that it has a higher affinity for the α1D-adrenergic receptor subtype than for the α1A subtype and has a superior efficacy to a placebo and comparable efficacy to other α1-blockers such as tamsulosin. The incidences of ejaculatory disorders and intraoperative floppy iris syndrome induced by naftopidil may also be lower than that for tamsulosin and silodosin, which have a high affinity for the α1A-adrenergic receptor subtype...
