Abstract
Intraoperative floppy iris syndrome (IFIS) is a cataract surgery complication that remains a challenge for eye surgeons. It is caused by the antagonism of alfa-1-adrenergic receptors within the dilator muscle of the iris, thus preventing the iris from dilation during a cataract surgery. The long-term blocking alfa-1 adrenergic receptors by the chronic use of a number of systemic medications may lead to permanent anatomical atrophy of the dilator muscle of the iris. The most common drugs associated with the development of IFIS are tamsulosin and other alpha-1 adrenergic receptor antagonists prescribed to patients with low urinary tract symptoms (LUTS). There are other systemic medications that have been reported to have increased risk for IFIS. It is crucial for the ophthalmologist to identify the high-risk patients prone to develop IFIS. Its presence may complicate the course of cataract surgery, ultimately negatively affecting visual outcome. Cataract surgery should be performed by an experienced eye surgeon using alternative pharmacological and surgical techniques. Interdisciplinary cooperation is essential to mitigate potential complications. Patients should be informed by their physicians about the need to report a medication history to their eye specialists, especially before cataract surgery.

Abstract
Intraoperative floppy-iris syndrome (IFIS) is an increasingly recognized condition that is proven to lead to higher rates of intraoperative complications. This study provides an updated systematic review and meta-analysis regarding all the identified factors predisposing to IFIS. The study was performed in accordance with the PRISMA guidelines. 38 studies were finally included in the meta-analysis. The factors that were found to predispose to IFIS significantly were male sex (odds ratio [OR], 4.25; CI, 2.58-7.01), hypertension (OR, 1.55; CI, 1.01-2.37), tamsulosin (OR, 31.06; CI, 13.74-70.22), finasteride (OR, 4.60; CI, 1.97-10.73), benzodiazepines (OR, 2.88; CI, 1.17-7.12), and antipsychotics intake (OR, 6.91; CI, 2.22-21.50). A decreased dilated pupil preoperatively was found predisposing to IFIS (weighted mean difference -0.93; CI, -1.19 to -0.67). Intracameral epinephrine, which was investigated as a potential prophylactic measure for preventing IFIS, did not reach statistical significance (OR, 0.29; CI, 0.08-1.06). A comprehensive preoperative assessment of all risk factors is vital to stratify the surgical risk, which is crucial in addressing IFIS because unanticipated IFIS could turn a routine surgery into one of significant visual morbidity.

Front Med (Lausanne) 2022; 9:941130. [PMID: 36111121 PMCID: PMC9468244 DOI: 10.3389/fmed.2022.941130] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2022] [Accepted: 08/10/2022] [Indexed: 12/03/2022] Open
Abstract
Selective α1-blockers are commonly administered to patients with lower urinary tract syndrome and benign prostatic hyperplasia, but may increase the risk of intraoperative floppy iris syndrome (IFIS). The purpose of this study aimed to clarify the risk of IFIS among various selective α1-blockers. Four databases were searched for prospective studies comparing alpha-1-antagonists. Data were pooled using the consistency model, and used risk ratio (RR) and mean difference (MD) for IFIS and pupil diameter, respectively. This study finally included 25 prospective comparative studies. Based on 51 direct comparisons with 6488 cases, risks of IFIS in patients who received tamsulosin [RR, 13.85; 95% confidence interval (CI): 7.34 to 26.11], terazosin (RR, 8.94; 95% CI 2.88 to 27.74), alfuzosin (RR, 7.73; 95% CI: 3.05 to 19.62), and doxazosin (RR, 3.88; 95% CI: 1.13 to 13.28) were significantly higher than those did not receive α1-antagonists. Based on 11 direct comparisons with 564 cases, as compared to no α1-antagonists, patients who received tamsulosin (MD, −0.36; 95% CI: −0.71 to −0.01) and alfuzosin (MD, −0.34; 95% CI: −0.62 to −0.07) showed smaller pupil diameter under mesopic light levels, while those received silodosin did not show significantly smaller mesopic pupil diameter than people without α1-antagonists. IFIS seems to be inevitable with the usage of α1-antagonists, and tamsulosin needs to be cautious due to the significantly higher risk of severe IFIS. With regard to silodosin, there is no strong evidence to support the uses of italthough it does not significantly decrease mesopic pupil diameter.

Abstract
PURPOSE OF REVIEW The aim of this study was to review and summarize recent findings and advancements regarding intraoperative floppy iris syndrome (IFIS). Although many improvements have been made for the management of IFIS, it remains a challenging condition for surgeons. An understanding of the syndrome as well as the multitude of tools to mitigate risk of complication is important for surgeons operating on high-risk patients. RECENT FINDINGS A variety of management approaches have been modified and improved or further supported with new data, such as intracameral compounds, intraoperative devices and surgical techniques. SUMMARY An understanding of risk factors is important for the identification of at-risk patients. A variety of approaches can greatly reduce incidence of IFIS complications. Multiple management strategies should be utilized to further reduce risk during these difficult surgeries.

Abstract
Tamsulosin is an antagonist of a subtype-specific alpha-1A- and alpha-1D-adrenoceptor (AR) that is expressed in the prostate gland, urethra, and bladder. Several reports have shown a possible relationship between ophthalmologic adverse effects and the use of alpha-1-receptor medicines, including tamsulosin. This descriptive review evaluates the intraoperative floppy iris syndrome (IFIS) associated with tamsulosin. A search of the Medline and PubMed databases was conducted to identify control trials, case reports, and observational examinations published in English. The publication dates were restricted (January 1, 2000, to January 1, 2020). Keywords (tamsulosin, alpha-blocker, ocular, eye, adverse reaction, and IFIS) were used in the searches. The searches identified 66 studies including in vitro or in vivo studies, trials, and observational studies. Twenty-two (33.33%) studies were articles citing tamsulosin and IFIS as having confirmed potential risk to ocular safety. The results of this review, including a comprehensive summary of published research on tamsulosin use in different populations, have identified several articles showing associations between tamsulosin and IFIS that merit further investigation. Suspending of potential causative pharmacological treatment of IFIS before ocular surgery including tamsulosin, proper identification of at-risk patients, preoperative prophylaxis treatments, and surgical technique modifications clearly can mitigate the anticipated risk of IFIS induced by tamsulosin.

Abstract
Almost fifteen years since its initial description, intraoperative floppy iris syndrome (IFIS) during phacoemulsification surgery remains a challenge for cataract surgeons in all its key aspects that include the stratification of the preoperative risk, preoperative prophylaxis treatment, surgery design and intraoperative management. Since its original association with tamsulosin intake, IFIS has been positively correlated with a plethora of risk factors which include: gender, age, hypertension, other a1-adrenergic receptor antagonists, finasteride, angiotensin II receptor inhibitors, benzodiazepines, antipsychotics, hypertension drugs and decreased dilated pupil diameter. The assessment and stratification of the preoperative risk is pivotal in screening patients prone to develop IFIS. For these patients, it is essential that preoperative prophylaxis, employment of necessary measures and surgical technique modifications are considered. A multidisciplinary approach of IFIS is a mandate, thus ophthalmologists, urologists and sometimes other specialties should cooperate to “educate” each other about the risks of their respective fields. They both must be aware of the joint statement on IFIS by the American Academy of Ophthalmology and the American Society of Cataract and Refractive Surgery which suggests either the initiation of tamsulosin after phacoemulsification or the use of a non-selective a1-ARA for benign prostatic hyperplasia treatment. In conclusion, awareness of the risk factors associated with IFIS and their detailed preoperative documentation is crucial in addressing IFIS. The lack of such an awareness can turn a routine, uneventful surgery into one with significant visual morbidity.

Abstract
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. Patients were classified as IFIS or non-IFIS after the surgery. Univariate and multivariate logistic regression analyses were performed. RESULTS The overall incidence of IFIS was 9.09% (29/319 eyes). The multivariate analysis revealed that tamsulosin use (P = 0.004), finasteride use (P = 0.014), and increasing age (P = 0.006) were significantly associated with IFIS. Male gender and benzodiazepine use were significantly associated with IFIS in the univariate analysis, but not in the multivariate analysis. The non-selective alpha1-ARA doxazosin was not found to be associated with IFIS. CONCLUSIONS The findings suggest that finasteride use and aging are risk factors for IFIS and confirm the association of tamsulosin use with IFIS. Further, doxazosin appears to be a relatively safe drug with respect to the occurrence of IFIS.

Abstract
PURPOSE OF REVIEW Intraoperative floppy iris syndrome (IFIS) occurs in 2% of cataract surgeries and is associated with an increased risk of surgical complications. These complications can be avoided when high-risk patients are identified by preoperative screening and appropriate measures are used intraoperatively. The purpose of this article is to review emerging risk factors for IFIS and to summarize management strategies used in IFIS. RECENT FINDINGS Although α1-antagonists in general, and tamsulosin (Flomax, Jalyn) in particular, have long been associated with IFIS, recent studies have more firmly demonstrated the elevated risk of IFIS attributed to tamsulosin. This resulted in a revision of the American Society of Cataract and Refractive Surgery/American Academy of Ophthalmology guidelines on IFIS. Our understanding of additional medications and medical conditions involved in IFIS is also evolving, including an appreciation that women are also susceptible to IFIS. New modifications of techniques used in the intraoperative management of IFIS are also discussed. SUMMARY Preoperative screening should include both men and women. Current or prior use of α1-antagonists and antipsychotics should be documented, along with hypertension. Surgeons should be prepared to employ a range of perioperative interventions in a graded response to IFIS of different severities.

Abstract
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. RESULTS Prevalence of tamsulosin use among men undergoing cataract surgery was 7.0% (41) with incidence of IFIS 4.78% (48). On multivariate analysis, hypertension (OR: 3.2, 95% confidence interval, 95% CI: 1.39-6.57; P = 0.005), use of tamsulosin (OR: 133.32, 95% CI: 50.43-352.48; P < 0.0001), or alfuzosin (OR: 9.36, 95% CI: 2.34-37.50; P = 0.002) were the factors associated with IFIS. Among men taking tamsulosin (n = 41) and alfuzosin (n = 28), 68.3% and 16.6% developed IFIS, respectively. In subgroup analysis of men on tamsulosin, no factor added to the risk posed by tamsulosin. Seventeen of 944 eyes not exposed to any drug had IFIS (0.018%). On subgroup analysis, only risk factor for IFIS was hypertension (OR: 4.67, 95% CI: 1.63-13.35; P = 0.002). Of 48 IFIS eyes, the surgeon observed increased difficulty in 57.1% (21) and additional measures were required in 9 eyes. Mean operative time was increased in IFIS eyes (11.68 ± 3.46 vs. 10.01 ± 0.22 min; P = 0.001). Surgical outcome was good in all cases. CONCLUSION The prevalence of tamsulosin intake and IFIS incidence is higher in India. Current tamsulosin/alfuzosin use and hypertension are important risk factors. IFIS makes the surgery more difficult, significantly prolongs the operative time, and predisposes for other intraoperative complications. However, with appropriate management, final operative outcome is not affected.

Abstract
PurposeTo evaluate risk factors for intraoperative floppy iris syndrome (IFIS) in patients undergoing phacoemulsification.MethodsParticipants in the study were 1274 consecutive patients, who underwent routine phacoemulsification cataract surgery. The following data were recorded and evaluated as possible risk factors: ophthalmological conditions, axial length of the eye, sociodemographic features, clinical data (hypertension and diabetes mellitus), medications being taken at the time of surgery, and duration of their intake. Cases were characterized intraoperatively as IFIS and non-IFIS. Univariate and multivariate logistic regression analysis were performed.ResultsIFIS was observed in 63/1274 eyes (4.9%, 95% CI: 3.9-6.7%). Current use of tamsulosin, alfuzosin, terazosin, benzodiazepines, quetiapine, and finasteride, as well as hypertension, were all independently associated with IFIS. Significant associations were noted for male sex, rivastigmine, and short axial length, which did not reach significance at the multivariate analysis. Duration of α-blockers intake was not found to be associated with IFIS.ConclusionApart from the well-established associations with α-blockers, this prospective study points to benzodiazepines, quetiapine, finasteride, and hypertension as potential risk factors for IFIS. Short axial length and rivastigmine were significantly associated with IFIS only at the univariate analysis.

Abstract
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. We recorded preoperative gender, age, α-antagonist medication, coexisting pseudoexfoliation (PXF), and intraoperative use of ophthalmic viscosurgical devices (OVDs), pupil size, complications, IFIS grading and the need for additional operative strategies to manage IFIS. Elongated corneal incisions were performed approximately 1 mm anterior to the limbus. RESULTS Ninety-three eyes of 81 men were included. Mean age was 76.5 years (range 55 to 96 years). Forty-seven eyes (40 patients) had documented use of alfuzosin and 45 eyes (40 patients) of tamsulosin. One patient received both. The overall rate of IFIS was 22.6 % (n = 21). Eyes of patients who were treated with alfuzosin had a milder grading (p < 0.001) and an overall lower percentage of IFIS compared to tamsulosin (4.26 % versus 42.22 % respectively, p < 0.001). No additional strategies were used to manage IFIS during surgery. No intraoperative complications occurred. CONCLUSION Anterior elongated incisions are simple and efficient in preventing IFIS, exempting the surgeon from the use of additional expensive devices or materials in most cases. They do not limit the surgeon to one strategy, and therefore, if necessary, another may be applied at any given time.

Abstract
CONTEXT It is well known that Alpha-1 adrenergic receptor antagonists affect the receptors in the prostate and also iris dilator muscle, leading to loss of iris muscle tone. OBJECTIVE To compare morphological alterations of iris secondary to tamsulosin and alfuzosin use. PARTICIPANTS Patients included in the study were grouped as follows: 16 patients treated with tamsulosin (Group 1), 14 patients treated with alfuzosin (Group 2) and 18 untreated controls (Group 3). MATERIALS AND METHODS All patients underwent ultrasound biomicroscopic and pupillometric examination. Iris thickness was measured at the dilator muscle region (DMR; measured at half of the distance between the scleral spur and the pupillary margin) and sphincter muscle region (SMR; Standardized at 0.75 mm from the pupillary margin). DMR/SMR was also calculated for each patient. Differences among groups were analysed. Main outcome measures were DMR, SMR, DMR/SMR and pupillary diameter. RESULTS Mean duration of treatments were 2.4 ± 0.96 years (1-4) and 2.3 ± 1.01 years (1-4) in Groups 1 and 2. Pupillary diameters were reduced in Groups 1-2 compared to Group 3 (p < 0.001, p < 0.001). The SMR was similar in Groups 1 and 2 (p: 0.114). These values were not significantly different from that of Group 3 (p: 0.196, p: 0.209). However, thickness in the DMR in Groups 1-2 were significantly lower than that of controls (Group 3) whereas there was no significant difference between Groups 1 and 2 (p: 0.041, p: 0.039 and 0.986, respectively). Mean DMR/SMR ratios were significantly lower in Groups 1-2 than that of Group 3 (p: 0.040 and p: 0.040, respectively). CONCLUSIONS In patients using these medications, the iris seems to be thinner at the dilator muscle region, but preserving the sphincter muscle region.

Abstract
Commonly prescribed urologic medications can have significant ophthalmologic side effects. The existing information can be conflicting. We looked at alpha-blockers and intraoperative floppy iris syndrome (IFIS), phosphodiesterase type 5 (PDE5) inhibitors and non-arteritic ischemic optic neuropathy (NAION) and lastly anticholinergic medications and glaucoma. There is no conclusive scientific data on what to do if the risk of urinary retention is low to moderate, however, we recommend that patients having cataract surgery should stop alpha-blocker medications preoperatively. If there is a high risk of urinary retention, the alpha-blocker should not be withheld, with the active involvement of the ophthalmologist. The role of using 5 alpha-reductase inhibitors (5ARIs) can be considered. There is no convincing evidence that PDE5 inhibitors cause non-arteritic anterior ischemic optic neuropathy (NAION), but patients should be advised of the possible risk of visual loss, especially in patients with risk factors of ischemic heart disease. Acute angle closure glaucoma (AACG or closed angle glaucoma) is very rarely caused by anticholinergic medications in patients with narrow angle anterior eye chambers. However, these medications are safe in patients with open angle glaucoma or treated closed angle glaucoma. Urologists should inquire about the patient's glaucoma history from his/her ophthalmologist before starting an anticholinergic medication.

Abstract
Intraoperative floppy iris syndrome (IFIS) has commonly been seen with long-term use of α1-adrenoceptor blocking agents. We observed IFIS in three patients during phacoemulsification due to oral imipramine therapy. The three patients took imipramine for 25 years, 10 months and 1 year, respectively. However, only the first patient was on oral therapy at the time of surgery, while the other two patients had stopped 4 months and 2 months prior to undergoing phacoemulsification. The first and third patients developed complete IFIS features, while the second had only partial IFIS characteristics. Phacoemulsification could be completed in all three patients without any complication. None of these patients had history of taking any of the α1-adrenoceptor blocking agents. This is the first anecdotal report of IFIS with the oral use of imipramine and hence further evidences are required to ascertain the association of oral imipramine therapy and IFIS. However, ophthalmologists undertaking phacoemulsification on patients on imipramine therapy should be alert for the occurrence of IFIS.

The effect of alpha antagonists on pupil dynamics: implications for the diagnosis of intraoperative floppy iris syndrome. Am J Ophthalmol 2012; 153:620-6.

Abstract
PURPOSE To assess pupil dynamics quantitatively in relation to the use of α1-adrenoceptor antagonists, which contribute to the features of intraoperative floppy iris syndrome, using a new, hand-held, digital pupillometer. DESIGN Prospective case-control study. METHODS We studied 15 and 25 patients administered tamsulosin and alfuzosin, respectively, as well as 25 control patients. Resting pupil diameter and subsequent contraction, latency, constriction velocity, and dilation velocity were recorded using an electronic pupillometer. All pupil measurements were performed before and after pharmacologic dilation. RESULTS In predilation pupillary measurements, we detected a significant decrease in maximum pupillary diameter by 0.50±0.19 mm (P=.011) and in the mean percentage of diameter reduction after stimulation (5.23±2.42%, P=.035) in the tamsulosin group. Alfuzosin also induced a significant decrease in maximum pupillary diameter (0.49±0.17 mm, P=.005). Constriction velocity was significantly reduced by 0.70±0.20 m/s (P=.001) in the tamsulosin group and by 0.54±0.18 m/s (P=.004) in the alfuzosin group. In terms of postdilation measurements, maximum and minimum pupil diameters were reduced significantly only in the tamsulosin group (by 1.09±0.31 mm [P=.001] and by 0.89±0.36 mm [P=.016], respectively). CONCLUSIONS We describe a reliable, accurate, and rapid method to acquire quantitative pupil measurements and identify the tendency for intraoperative floppy iris syndrome before cataract surgery after the use of alfuzosin and tamsulosin. This investigation also analyzed the similarities and differences induced by the 2 drugs in predilation and postdilation pupil dynamics, demonstrating that tamsulosin is more potent than alfuzosin in inducing intraoperative floppy iris syndrome.

Abstract
UNLABELLED A 47-year-old man who had been using finasteride for male pattern alopecia for 4 years complained of progressive bilateral blurring of vision. His general health had been good, and he was not on any other long-term medication. Examination showed bilateral anterior subcapsular cataracts. Phacoemulsification and insertion of intraocular lenses were performed, and both eyes showed features of intraoperative floppy-iris syndrome (IFIS), including undulation and billowing of the iris, iris prolapse, and pupil constriction. We believe the use of finasteride can be associated with cataract formation and IFIS. Ophthalmologists and physicians prescribing finasteride should be aware of this possible association.
