Abstract
The management of benign prostatic obstruction (BPO) should involve a treatment algorithm that takes into account prostate size, and patient's symptoms and preference with the aim of helping with urinary symptoms and enhance quality of life. The diagnostic assessment for men with lower urinary tract symptoms (LUTS) should be comprehensive to help choose the best management strategy. Strategies from lifestyle modifications to medical treatment with alpha blockers and/or 5-alpha-reductase inhibitors to surgical procedures can all be used in the management algorithm. Surgical management ranges from transurethral resection of prostate (TURP) to minimally invasive surgical therapies (MIST) including laser therapies such as Holmium laser enucleation (HoLEP) and photoselective vaporisation (PVP), aquablation, Rezūm system, prostate artery embolisation (PAE), prostatic urethral lift (PUL), temporary implantable nitinol device (iTind) and Optilume BPH catheter system. BPO is a common urological condition that has a significant impact on quality of life and economic burden globally and is likely to become increasingly prevalent with an ageing population. Selecting the most appropriate treatment modality will depend on the individual patient preferences, availability of resources, cost, anatomical factors and the goals of treatment.

Abstract
INTRODUCTION Benign prostatic hyperplasia (BPH) represents the histological entity of prostate cell proliferation, which inflicts a gradually increasing obstruction of the bladder outlet and is accompanied by a progressing manifestation of lower urinary tract symptoms (LUTS). BPH management algorithm includes conservative measures, pharmaceutical agents, and surgical procedures. AREAS COVERED A comprehensive literature review was performed using PubMed, Scopus, and Google Scholar databases to identify publications written in English, analyzing BPH pharmaceutical treatment. The search was conducted from January 2000 to January 2023. Six main drug classes can be administered, either as monotherapy or in combination. Furthermore, the authors provide current direction of research on future medications, which focuses on a more etiological interference to the BPH pathophysiological mechanism. EXPERT OPINION The available medications represent an effective first-line step of BPH/LUTS therapy. Currently, the administration of BPH medications is tailored to patient/disease characteristics and entails long-time adherence to therapy. The emergence of new surgical modalities, which combine significantly lower morbidity compared to standard procedures and more durable effects than the available medications, seems to challenge the current treatment algorithm. More direct comparisons and the increasing experience with these surgical modalities will delineate the switch points between various therapy levels along the BPH management sequence.

Abstract
INTRODUCTION The drug classes of α1-adrenoceptor antagonists, 5α-reductase inhibitors, and phosphodiesterase type 5 inhibitors are guideline-recommended treatments of lower urinary tract symptoms suggestive of benign prostatic hyperplasia; muscarinic receptor antagonists and β3-adrenoceptor agonists are also recommended if storage symptoms are insufficiently addressed with one of the other three drug classes. AREAS COVERED We provide a narrative review (no formalized literature searches performed) of the tolerability of these drug classes with emphasis on the more recently introduced medications, on combination treatment, and on more lately emerging risks. EXPERT OPINION/COMMENTARY The tolerability profiles are distinct between drug classes but, with few exceptions, similar within a drug class. Within a drug, formulations with longer duration of action tend to have better tolerability. Efficacy gains using combination treatment at least partly come at a cost of lesser tolerability. Greater susceptibility to experience adverse events based on age, comorbidities, and comedications appears conceptually important but remains under-investigated in this therapeutic area.

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
α1-Adrenergic receptors (ARs) are members of the G-Protein Coupled Receptor superfamily and with other related receptors (β and α2), they are involved in regulating the sympathetic nervous system through binding and activation by norepinephrine and epinephrine. Traditionally, α1-AR antagonists were first used as anti-hypertensives, as α1-AR activation increases vasoconstriction, but they are not a first-line use at present. The current usage of α1-AR antagonists increases urinary flow in benign prostatic hyperplasia. α1-AR agonists are used in septic shock, but the increased blood pressure response limits use for other conditions. However, with the advent of genetic-based animal models of the subtypes, drug design of highly selective ligands, scientists have discovered potentially newer uses for both agonists and antagonists of the α1-AR. In this review, we highlight newer treatment potential for α1A-AR agonists (heart failure, ischemia, and Alzheimer's disease) and non-selective α1-AR antagonists (COVID-19/SARS, Parkinson's disease, and posttraumatic stress disorder). While the studies reviewed here are still preclinical in cell lines and rodent disease models or have undergone initial clinical trials, potential therapeutics discussed here should not be used for non-approved conditions.

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.

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
BACKGROUND Tamsulosin is one of the most commonly prescribed alpha-1A antagonists for the treatment of benign prostatic syndrome (BPS). Patients treated with tamsulosin often develop intraoperative floppy iris syndrome (IFIS) during cataract surgery. This leads to increasing miosis and an undulating iris, which increases the risk of complications significantly and can cause permanent damage. AIM OF THE WORK The aim is to raise awareness for the effects of tamsulosin intake before cataract surgery. MATERIAL AND METHODS We conducted a critical review of publications on the association of IFIS in cataract surgery with alpha-receptor blockers. RESULTS AND DISCUSSION Tamsulosin has a risk of complications of up to 80 %, whereas doxazosin and alfuzosin only have a 15-20 % chance of complications. Tamsulosin therefore represents a significant risk factor for permanent secondary damage after cataract surgery. Even after discontinuing tamsulosin, IFIS was still observed after up to 3 years. Nevertheless, pausing of tamsulosin intake is recommended. An alternative preparation should therefore be preferred in patients who have not yet had cataract surgery. If patients are already pseudophakic, tamsulosin can be given without concern.

Abstract
Objective To evaluate the literature related to the use of alpha1-blockers and the risk of intraoperative floppy iris syndrome (IFIS), particularly in cataract surgery. IFIS is characterized by floppiness or billowing of the iris, iris prolapse, and progressive miosis, possibly leading to severe complications. It is thought to be associated with adrenergic alpha-1 receptor antagonists commonly used to treat lower urinary tract symptoms in patients with benign prostatic hyperplasia. Data Sources A literature search was conducted in Pubmed, EMBASE, and Web of Science through May 2021 with MeSH terms and keywords 'intraoperative floppy iris syndrome,' ' adrenergic alpha-1 receptor antagonists,' and 'cataract surgery.' Study Selection and Data Extraction Relevant articles were reviewed and included. In addition, reference lists from identified publications were reviewed to identify additional reports and studies of interest. Data Synthesis Numerous reports have linked IFIS to multiple risk factors including age, gender, hypertension, and the use of adrenergic alpha-1 receptor antagonists, most notably tamsulosin. Tamsulosin selectively blocks the adrenergic alpha-1 receptor in the iris dilator muscle, preventing mydriasis during cataract surgery. Other adrenergic alpha-1 receptor antagonists, including terazosin, doxazosin, alfuzosin, and sildosin, have also been linked to IFIS; however, their relationship to IFIS is not as well defined. Conclusion Patients should be educated regarding potential adverse effects and discuss this with their health care providers prior to cataract surgery. In addition, health care providers should be aware of the adverse effect and take steps to reduce the risk of surgical complications.

Abstract
Globally, 2.2 billion people live with some form of vision impairment and/or eye disease. To date, most systematic reviews examining associations have focused on a single eye disease and there is no systematic evaluation of the relationships between eye diseases and diverse physical and mental health outcomes. Moreover, the strength and reliability of the literature is unclear. We performed an umbrella review of observational studies with meta analyses for any physical and/or mental comorbidities associated with eye disease. For each association, random-effects summary effect size, heterogeneity, small-study effect, excess significance bias and 95% prediction intervals were calculated, and used to grade significant evidence from convincing to weak. 34 studies were included covering 58 outcomes. No outcomes yielded convincing evidence, six outcomes yielded highly suggestive results (cataract positively associated with type 2 diabetes, open-angled glaucoma positively associated with myopia and diabetes, diabetic retinopathy positively associated with cardiovascular disease and cardiovascular mortality, and retinopathy of prematurity positively associated with chorioamnionitis), eight outcomes yielded suggestive results (diabetic retinopathy positively associated with all-cause mortality and depression, diabetic macular oedema positively associated with dyslipidaemia, cataract positively associated with gout, nuclear sclerosis positively associated with all-cause mortality, open angled glaucoma positively associated with migraine and hypertension, and age-related macular degeneration positively associated with diabetes), and 18 outcomes yielded weak evidence. Results show highly suggestive or suggestive evidence for associations between several types of eye diseases with several comorbid outcomes. Practitioners and public health policies should note these findings when developing healthcare policies.

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
PURPOSE To examine the efficacy of preoperative administration of topical atropine 1% and non-steroidal anti-inflammatory drugs (NSAIDs) for prevention of intraoperative floppy iris syndrome (IFIS). METHODS In this retrospective cohort study, patients who underwent cataract surgery by phacoemulsification between July 2019 and February 2020 in two hospitals were included. Both hospitals are located in central Israel, have similar patient demographics and employ similar surgical techniques. They, however, differ in policy of IFIS prevention. In Meir Medical Center no preventive medications are given pre-operatively, while in Shamir Medical Center patients at-risk for IFIS receive topical atropine 1% once daily and non-steroidal anti-inflammatory drugs (NSAIDs) thrice daily for 3 days preoperatively. RESULTS Overall, 207 eyes of 207 patients with history of alpha-antagonist use were included. Mean age was 74.9 ± 7.8 years and 82.1% (n = 170) were male. Among patients from the pretreating center 86.8% (n = 92/106) were pre-treated with either NSAIDs or atropine preoperatively, while in the non-pretreating center no treatment was prescribed (n = 0/101). IFIS rate among the non-pretreating center was 29.7% (n = 30/101) compared to 15.1% (n = 16/106) in the pretreating center (p = 0.012). When strictly comparing treated to untreated patients, the treated group had an IFIS rate of 12.0% compared to 30.4% among untreated (p = 0.001). Adjusted for age and gender results remain consistent (odds ratio 0.329 for treated patients, 95% confidence interval: 0.150-0.720; p = 0.005). CONCLUSIONS IFIS rates were significantly lower in the pretreating center compared to the non-pretreating center. When comparing strictly treated to untreated patients, differences were even more pronounced.

Management and outcomes of the small pupil in cataract surgery: iris hooks, Malyugin ring or phenylephrine? Eye (Lond) 2021; 35:2714-2718. [PMID: 33184489 PMCID: PMC8452752 DOI: 10.1038/s41433-020-01277-0] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2020] [Revised: 09/23/2020] [Accepted: 10/30/2020] [Indexed: 02/04/2023] Open
Abstract
PURPOSE To investigate outcomes for small versus large pupils in cataract surgery using different pupil expansion techniques. METHODS Retrospective case-series reviewing 20,175 patients' cataract surgery electronic medical records at Moorfields Eye Clinic in Bedford Hospital NHS Trust from January 2010 to April 2020. Outcomes such as visual acuity (VA), intraocular pressure, intraoperative, post-operative complications were recorded and small pupil expansion device outcome. RESULTS One thousand, four hundred twenty-six patients were identified as having small pupil (SP). Of these, 1110 patients (77.8%) had interventions to expand the pupil including 447 (31.3%) with intracameral phenylephrine (IC PE) alone, 194 (13.6%) with iris hooks and 469 (32.9%) with a Malyugin ring. The large pupil (LP) group had a statistically significant greater gain in VA than the SP group (p < 0.05). SPs had a significantly higher rate of intraocular complications including posterior capsular rupture (PCR) with vitreous loss (OR 2.75, p < 0.001). There was also a significantly higher rate of post-operative complications such as corneal oedema (OR 2.64, p < 0.001) and anterior uveitis (OR 2.11, p < 0.001) in the SP group. However, VA improvement and complications between the different pupil expansion groups showed no significant differences (p > 0.05) except for a greater rate of iris tears in the Malyugin group (p < 0.05). CONCLUSION To date, this is the largest reported case-series comparing Malyugin rings and iris hooks with other pupil expansion techniques. The various techniques to expand pupil size appear to be safe and equally effective in improving VA with a similar rate of complications except for a greater rate of iris tears with Malyugin ring.

Abstract
PURPOSE Spin-the misrepresentation of study findings such that the beneficial effects of an intervention are magnified beyond what the results actually show-is a reporting practice that has been shown to influence perceptions of treatment efficacy and clinical decision making. We evaluated the extent of spin in the abstracts of systematic reviews of cataract surgery and its complications. We also evaluated whether particular study attributes were associated with spin. DESIGN Cross-sectional study. METHODS We searched MEDLINE and Embase for systematic reviews and meta-analyses relating to cataract treatment. From these search records, screening for eligible studies was done in duplicate. Using a previously developed classification system for spin, we assessed the systematic reviews that met our eligibility criteria for the occurrence of the 9 most severe forms of spin. We performed the evaluation of spin, extracted study characteristics, and appraised the methodological quality of each study using the 16-question AMSTAR-2 scale in duplicate. RESULTS Searches retrieved 2,059 studies, of which 110 were eligible for data extraction. We found at least 1 form of spin in 30.0% of included systematic reviews (33/110). Six of the 9 types of spin were identified in our sample, the most common being type 3 in 18.2% (20/110) of abstracts. We found no significant association between spin in abstracts, AMSTAR-2 appraisal, and any of the extracted study characteristics. CONCLUSION Spin was evident in approximately one-third of the abstracts of evaluated systematic reviews and meta-analyses of cataract surgery and associated complications.

Abstract
BACKGROUND Benign prostatic hyperplasia (BPH) is characterized by the occurrence of.disorders of urine storage and bladder emptying. Most men over the age of 60 years are affected to some degree. METHODS A selective literature search with additional scrutiny of guidelines and meta-analyses. RESULTS The management of patients with BPH is complex. Emptying and retention disorders can be treated by various pharmacological and surgical means. Transurethral resection of the prostate (TURP) has long been considered the gold standard for operative treatment. Transurethral enucleation procedures show a better risk profile in some uses, however, and have, above all, largely displaced suprapubic prostatectomy. Numerous innovative treatment options have been developed in recent years, but their long-term effects remain to be determined. These treatment techniques can nevertheless be used in individual cases after thorough discussion with the patient. CONCLUSION The care of patients with BPH should be interdisciplinary. The efficacy and safety of many new developments in the area of pharmacological and minimally invasive treatment remain to be demonstrated in randomized trials.

Abstract
PURPOSE To assess structural risk factors for intraoperative floppy iris syndrome (IFIS) available on preoperative examination before cataract surgery. METHODS In this retrospective study, medical records of patients who underwent cataract surgery in Shamir Medical Center, between July and September 2019, were reviewed. Patients younger than 50 years, with preexisting ocular conditions affecting the pupillary size or anterior chamber depth (ACD), and combined procedures were excluded. Association of IFIS with preoperative ocular parameters was tested using uni- and multivariant analyses. RESULTS Overall, 394 eyes of 394 patients were included. The mean age was 72.48 ± 8.63 years, and 58.4% were female. IFIS occurred in 18 eyes (4.6%), seven (38.89%) of which had been previously treated with alpha-antagonists. Patients in the IFIS group were significantly older compared with those in the non-IFIS group (78.1 ± 6.7 vs. 72.2 ± 8.6 years, P = 0.005), with no significant gender difference. The mydriatic pupil diameter was significantly smaller in the IFIS group (5.73 ± 1.16 vs. 6.97 ± 1.03 mm, P < 0.001), and the lens thickness (LT) was larger (4.93 ± 0.42 vs. 4.49 ± 0.42 mm, P = 0.001). ACD was inversely correlated with LT (r = - 0.613, P < 0.001) and positively correlated with pupil diameter (r = 0.252, P < 0.001). On univariate analysis, ACD was significantly shallower in the IFIS group (2.88 ± 0.49 vs. 3.14 ± 0.39 mm, P = 0.008). In multivariant analysis controlling for alpha-antagonist use, both LT and mydriatic pupil diameter remained significantly predictive of IFIS (LT: OR 9.9, 95%CI 1.9-49, P = 0.005; pupil diameter OR 0.427, 95%CI 0.26-0.69, P < 0.001). CONCLUSIONS Increased LT and decreased mydriatic pupil diameter were associated with increased IFIS risk regardless of alpha-antagonist treatment status.

Abstract
Purpose: To evaluate the effect of Mydrane (contains tropicamide, phenylephrine hydrochloride, and lidocaine hydrochloride) on time needed to induce mydriasis and mydriasis stability during cataract surgery. Methods: This was an observational, non-interventional, multicenter study of patients undergoing cataract surgery who received Mydrane for mydriasis and intraocular anesthesia. The study was conducted at seven ophthalmology departments at university hospitals in Poland. Patients admitted for cataract surgery within a 2-week period were asked to participate in the study. Patients whose pupils dilated to a diameter ≥6 mm after topical mydriatic administration during preoperative examinations were scheduled to receive Mydrane and included in the registry. No additional inclusion criteria were used. Patients' medical histories, examination results, and operative details were recorded. Pupil diameter was measured during surgery. Surgeons were asked to complete a Likert-based survey in parallel. Results: A total of 307 patients were enrolled. The mean pupil diameter was 7.0 ± 1.0 mm before capsulorhexis and 6.9 ± 1.2 mm before lens implementation. A pupil diameter ≥6 mm was achieved in 91.9% and 87.6% of patients before capsulorhexis and lens implantation, respectively. We asked 58 surgeons whether they agreed with the statement "Mydriasis was obtained in a short time after the administration of Mydrane"; the surgeons agreed with this statement after 92.2% (283/307) of surgeries. In addition, after 88.2% of surgeries, the surgeons agreed with the statement "Mydriasis was stable after the administration of Mydrane." Conclusions: Mydriasis was rapidly and stably obtained after Mydrane injection, as demonstrated by pupil diameter measurements during surgery and surgeons' feedback.

Abstract
Intraoperative floppy iris syndrome (IFIS) is characterized by intraoperative floppiness or billowing of the iris, progressive miosis, and iris prolapse through the surgical wounds. It was originally reported about fifteen years ago, which was later identified to be closely associated with tamsulosin, the most commonly used α1 adrenoceptor antagonist for benign prostatic hyperplasia (BPH). A variety of risk factors, including age, gender, hypertension, axial length of the eye, 5α-reductase inhibitors, other α adrenoceptor antagonist and neuromodulators, have been connected with IFIS. If IFIS occurs during phacoemulsification surgery, complications such as corneal endothelial loss, iris trauma, posterior capsule rupture (PCR), high intraocular pressure and vitreous loss are significantly increased. Therefore, preoperative evaluation of high-risk patients and appropriate intraoperative intervention is crucial to avoid severe complications. This review summarizes the pathogenesis and clinical features of classic IFIS, and provides some clinical pearls to ophthalmologists that may help identify, prevent or reduce IFIS associated complications. Additionally, from the perspective of clinical occurrence of IFIS, there are some recommendations for urologists as well. In conclusion, both ophthalmologists and urologists should be aware of this special clinical situation and communicate with each other about their own fields. A multidisciplinary interaction is of importance to simplify potentially complicated clinical issues.

Abstract
The diagnosis and treatment of lower urinary tract symptoms (LUTS) due to benign prostatic enlargement plays an important role in daily urological practice. Therefore, a targeted and resource-saving approach is essential. A rational base-line work-up of our patients provides the necessary information for obtaining the diagnosis and only needs to be expanded in individual cases. In addition to drug therapy, the modification of lifestyle and the possibility of watchful waiting must not be underestimated. Simple measures such as a timed fluid intake, double micturition in the case of residual urine development, but also bladder reconditioning can significantly improve the quality of life of our patients. Regarding surgical treatment, laser procedures have found their way into many departments and have established themselves in daily routine as a reference procedure in addition to transurethral resection of the prostate (TUR-P) and simple open prostatectomy. New, minimally invasive procedures-such as prostatic artery embolization (PAE), the Rezum™- (NxThera Inc., Maple-Grove, MN, USA) or the Aquabeam® (Procept, Redwood City, CA, USA) procedure, but also nonablative procedures such as iTind© (TIND, Medi-Tate, Or Akiva, Israel) or Urolift® (Neotract Inc., Pleasanton, CA, USA)-offer new treatment options to those affected, with the potential to maintain patient's sexual function. As a result, individual risk assessment and advice on the advantages and disadvantages of all available treatment options-even more than today-will be an important part of LUTS treatment. An individual approach, similar to that used in the treatment of oncological disease, will become standard also in the treatment of benign prostatic syndrome.

Abstract
Intraoperative floppy iris syndrome (IFIS) is described by three characteristics: floppy iris that billows in reaction to intraocular fluid currents during phacoemulsification surgery, flaccid iris stroma that tends to prolapse through well-constructed surgical incisions, and progressive pupillary miosis despite preoperative pharmacologic dilatation. A 63-year-old man presented with decreased vision in both his eyes. Ophthalmic examination revealed bilateral nuclear cataract. He was prescribed silodosin for the management of benign prostatic hyperplasia a month ago. Consecutive cataract surgery was planned at a 2-week time interval. All features of IFIS were encountered in both eyes of the patient during phacoemulsification surgery. IFIS was successfully managed by the aid of an iris retractor, and a 20/20 final visual acuity was achieved postoperatively in both eyes of the patient. To the best of our knowledge, this is the first study about bilateral IFIS associated with silodosin intake. Ophthalmologists and urologists prescribing silodosin should be aware of this possible association.

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
Importance Trustworthy clinical practice guidelines require reliable systematic reviews of the evidence to support recommendations. Since 2016, the American Academy of Ophthalmology (AAO) has partnered with Cochrane Eyes and Vision US Satellite to update their guidelines, the Preferred Practice Patterns (PPP). Objective To describe experiences and findings related to identifying reliable systematic reviews that support topics likely to be addressed in the 2016 update of the 2011 AAO PPP guidelines on cataract in the adult eye. Design, Setting, and Participants Cross-sectional study. Systematic reviews on the management of cataract were searched for in an established database. Each relevant systematic review was mapped to 1 or more of the 24 management categories listed under the Management section of the table of contents of the 2011 AAO PPP guidelines. Data were extracted to determine the reliability of each systematic review using prespecified criteria, and the reliable systematic reviews were examined to find whether they were referenced in the 2016 AAO PPP guidelines. For comparison, we assessed whether the reliable systematic reviews published before February 2010 the last search date of the 2011 AAO PPP guidelines were referenced in the 2011 AAO PPP guidelines. Cochrane Eyes and Vision US Satellite did not provide systematic reviews to the AAO during the development of the 2011 AAO PPP guidelines. Main Outcomes and Measures Systematic review reliability was defined by reporting eligibility criteria, performing a comprehensive literature search, assessing methodologic quality of included studies, using appropriate methods for meta-analysis, and basing conclusions on review findings. Results From 99 systematic reviews on management of cataract, 46 (46%) were classified as reliable. No evidence that a comprehensive search had been conducted was the most common reason a review was classified as unreliable. All 46 reliable systematic reviews were cited in the 2016 AAO PPP guidelines, and 8 of 15 available reliable reviews (53%) were cited in the 2011 PPP guidelines. Conclusions and Relevance The partnership between Cochrane Eyes and Vision US Satellite and the AAO provides the AAO access to an evidence base of relevant and reliable systematic reviews, thereby supporting robust and efficient clinical practice guidelines development to improve the quality of eye care.

Abstract
Male lower urinary tract symptoms are frequently due to benign prostatic enlargement. Medical therapy is strongly recommended in patients with moderate to severe symptoms. Lower urinary tract symptoms may require a different medical approach using drugs with different mechanisms of action. Alpha-1 blockers, muscarinic receptor antagonists and phosphodiesterase type 5 inhibitors are the most frequently used drugs. 5-Alpha reductase inhibitors are commonly prescribed to reduce prostate volume and to prevent benign prostatic hyperplasia progression. Currently, medical treatment of lower urinary tract symptoms suggestive of benign prostatic enlargement can be tailored according to different symptom characteristics and severity, and to different patient comorbidities and preferences. For this reason, the decision-making process should be based on an accurate patient counselling with detailed clarification of potential benefits and, above all, potential side effects of different drugs. This non-systematic review of the literature presents an update of the current options for medical treatment of lower urinary tract symptoms suggestive of benign prostatic enlargement, helping urologists in the decision-making and counselling process.

Abstract
PURPOSE To evaluate modified anterior elongated corneal incisions as a simple technique to reduce the incidence and severity of intraoperative floppy iris syndrome (IFIS), in patients taking tamsulosin (a selective α1a-adrenergic receptor antagonist). METHODS This prospective case series was conducted at Meir Medical Center, a tertiary care facility in Israel. Included were 45 eyes of 39 male patients taking tamsulosin, and thus prone to IFIS. Patients underwent phacoemulsification cataract surgery with anterior elongated corneal incisions. The primary outcomes were the incidence and severity of IFIS, the complication rate and the need for additional IFIS management techniques. The secondary outcome was to quantify the surgically induced astigmatism, using Alpin's vector analysis. The tamsulosin treatment period and pupil diameter during five stages of the surgery were also noted. RESULTS The overall rate of IFIS was 33.33% (n = 15). The IFIS severity was rated as mild in 22.22% and moderate in 11.11% of the study eyes. No IFIS was noted in 66.67% of the eyes. There were no cases of severe IFIS, and no need for other IFIS management strategies. The complications rate was 2.22% (n = 1). Patients who developed IFIS had a significantly smaller pupil at the beginning of surgery (p < 0.05). There was no significant difference in tamsulosin treatment period between patients with and without IFIS (p = 0.19). The centroid - the mean SIA vector was 0.51 D @ 18° ±1.5 D (SD). CONCLUSIONS In tamsulosin treated patients, using modified corneal incisions may be feasible in order to reduce the incidence and severity of IFIS during cataract surgery. Future randomized studies are warranted.

Abstract
Introduction In order to investigate the efficacy and safety of Afalaza in men with benign prostatic hyperplasia (BPH) at risk of progression, this multicenter, double-blind, placebo-controlled, randomized clinical trial was performed. Derived by technological treatment of antibodies to prostate-specific antigen (PSA) and endothelial nitric oxide synthase (eNOs), Afalaza was previously proved to modulate its molecular targets. The mechanism of action of the drug is associated with the modulating effect of the antibiodies (RA-Abs) on the molecular targets (PSA and eNOS) by way of conformational changes. Material and methods A total of 249 patients aged 45–60 years with BPH and moderate lower urinary tract symptoms (LUTS), total prostate volume (TPV) ≥30 cm3, Qmax 10–15 ml/s, and serum PSA<4 ng/ml were randomly assigned to receive either Afalaza (n = 125) or placebo (n = 124) for 12 months. Changes in BPH/LUTS symptoms (according to the International Prostate Symptom Score), Qmax, TPV, PSA, BPH clinical progression, occurrence of acure urinary retention (AUR) events or BPH-related surgery were estimated as the study endpoints. Results IPSS mean change was -3.7 ±3.0 (95% CI -4.3 to -3.2) after 12 months of Afalaza (vs. -2.9 ±2.4; 95% CI -3.3 to -2.4 in placebo; р = 0.02). Qmax growth was 2.5 ±4.3 ml/s (vs. 1.4 ±3.3 in placebo; p = 0.049), TPV reduced by 11.8 ±16.0% (vs. 6.5 ±14.7%; p = 0.01, and PSA remained unchanged. Afalaza therapy resulted in a significant decrease in the total sum of BPH progression symptoms (p = 0.01). The maximum effect of Afalaza was registered after 12 months without a tendency to form a ‘plateau’. During the study, no patients experienced AUR or BPH-related surgery. Conclusions A 12-month course of Afalaza therapy is effective and safe for patients with BPH. The results of end points measurements revealed asignificant advantage of Afalaza compared to placebo in the overall symptoms benefit and a decline in the risk of BPH progression.

Abstract
Purpose To predict development of intraoperative floppy iris syndrome (IFIS) using the preoperative pharmacologically dilated pupil-to-limbal diameter (PL) ratio. Methods The subjects were male patients treated by phacoemulsification who were or were not taking α1-adrenoceptor antagonists (ARAs). The PL ratio was calculated from the horizontal dilated pupil diameter and the horizontal corneal white-to-white distance measured by two observers in surgical videos. IFIS severity was graded using the criteria of Chang et al. We predicted the intuitive PL ratio to describe how precisely the experimenter can estimate the PL ratio without any tools. Results There were 36 eyes in the α1-ARA group and 48 eyes in the control group. The pupil diameter and PL ratio were both significantly smaller in the α1-ARA group compared to the control group (p < 0.001). All of pupil diameter, PL ratio, and intuitive PL ratio were negatively correlated with IFIS severity. The cutoff value for prediction of IFIS from the ROC curve was 7.20 mm for the pupil diameter, 58.7% for the PL ratio, and 62.5% for the intuitive PL ratio. The AUC for the ROC curve using the PL ratio (0.913) and intuitive PL ratio (0.892) did not perform substantially worse than that for the ROC curve based on the pupil diameter (0.875). Conclusions The PL ratio is a simple and useful parameter for compensated prediction of IFIS development. Patients in whom this ratio is <60% are particularly likely to develop IFIS, and measures against onset of IFIS should be considered. This study is registered with UMIN000033012.

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
Medical therapy for clinical benign prostatic hyperplasia (BPH) has advanced significantly in the last 2 decades. Many new α1 antagonists and 5α reductase inhibitors (5ARi) are now commercially available. The practicing urologist must decide on the most appropriate medication for his patients, taking into consideration various factors like efficacy, dosing regime, adverse effects, cost, patient's socioeconomic background, expectations, drug availability and his own clinical experience. The use of combination therapy added further to the complexity in clinical judgment when prescribing. We highlight some of the key points in prescribing α1 antagonists, 5ARi and their combination, based on our viewpoints and experience as urologists in an Asian clinical setting.

Abstract
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. The complications range from poor visibility of the operative field to iris damage with the surgical instruments and to rupture of the posterior capsule, with loss of lens material into the vitreous body. Material and methods A comprehensive literature review was performed using MEDLINE with MeSH terms and keywords 'benign prostatic hyperplasia', 'intraoperative floppy iris syndrome', 'adrenergic alpha-antagonist' and 'cataract surgery'. In addition, reference lists from identified publications were reviewed to identify reports and studies of interest from 2001 to 2017. Results The A total of 95% of experienced ophthalmologic surgeons reported that systematic treatment with tamsulosin represents a challenging surgical condition increasing the risk of complications. Alpha-blockers are commonly prescribed, with 1,079,505 packages of tamsulosin prescribed each month in 2014 in Austria. Dose modification may be one way to reduce the risk of IFIS. A lower incidence of IFIS was reported in patients on tamsulosin in Japan, but the recommended dosage was lower than that used in Europe and the US (0.2 mg vs. 0.4 mg). Conclusions We showed that not all patients taking tamsulosin experience IFIS. Moreover, larger investigations with a prospective design are needed, including studies to monitor the pre- and post-therapeutic ophthalmologic changes under tamsulosin, as well as urodynamic improvements resulting from this therapy.

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
PURPOSE To evaluate the association between intraoperative floppy iris syndrome (IFIS) and concurrent medications containing selective alpha1A receptor antagonists as well as nonselective alpha1-adrenergic receptor antagonists, bulbus length, patient age and gender. METHODS We performed a prospective data acquisition of IFIS occurrence and grading, and retrospective evaluation of concurrent medications, bulbus length, patient age and gender of all patients undergoing cataract surgery over a 6-month period. RESULTS IFIS was observed in 119 of 947 cases (12.6 %). 31 of those 119 patients (26.1 %) had a concurrent medication with a drug that is associated with a higher risk of causing IFIS. Tamsulosin was the drug most commonly associated with IFIS (n = 11), followed by a combination of drugs (n = 7), doxazosin (n = 4), quetiapine (n = 4), finasterid (n = 2), prothipendyl (n = 2), and mianserin (n = 1). Bulbus length and age did not show any significant association with occurrence or grade of IFIS. Gender distribution among IFIS cases was 57.1 % males (n = 68) and 42.9 % (n = 51) females. CONCLUSIONS The occurrence of IFIS has to be expected with a variety of concurrent medications. The number of IFIS cases and the percentage of females in this series are higher compared to previous reports. The observations might be due to a rising awareness of surgeons or to an increasing number of causative medications on the market.

Saudi J Ophthalmol 2016; 30:150-156. [PMID: 28210174 PMCID: PMC5299114 DOI: 10.1016/j.sjopt.2016.07.005] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2015] [Revised: 05/30/2016] [Accepted: 07/25/2016] [Indexed: 11/24/2022] Open
Abstract
Purpose The aim of this study was to quantify changes and reversibility in pupil dilation and iris dilator muscle region thickness associated with introduction and subsequent discontinuation of tamsulosin in patients naïve to this drug with the aid of an anterior OCT system. Methods The study was carried out on 7 patients (14 eyes) naïve to tamsulosin and with benign prostatic hypertrophy (BHP). Measurements taken by Vistante OCT were done pre- and post-dilation of the following: pupil size, iris dilator muscle region (DMR) thickness, sphincter muscle region (SMR) thickness, and anterior chamber depth. These measurement were taken at Day 0 (tamsulosin naive), Day 30 (after one month of tamsulosin, the treatment period) and day 60 (after one month of no tamsulosin, the discontinuation period). Results Post-dilation pupil diameter significantly increased during the discontinuation period (P = 0.047). Iris DMR thickness measurements post-dilation significantly decreased during treatment (P = 0.00044), discontinuation (0.00011), and combined periods (P = 0.000050). Anterior chamber depth measurements in post-dilation were significantly decreased during treatment (P = 0.0016), discontinuation (P = 0.017), and combined periods (P = 0.00022). Conclusion Tamsulosin discontinuation effectively increases dilated pupil size, a measure that has been inversely linked to IFIS incidence pre-operatively. Decreased DMR thickness in this short term likely illustrates changes aside from atrophy, such as vascular changes. Decreased anterior chamber depths suggest aqueous humor production is decreased as well.

Abstract
OBJECTIVE To calculate the associations between Medicare payment and service volume for complex and noncomplex cataract surgeries. DATA SOURCES The 2005-2009 CMS Part B National Summary Data Files, CMS Part B Carrier Summary Data Files, and the Medicare Physician Fee Schedule. STUDY DESIGN Conducting a retrospective, longitudinal analysis using a fixed-effects model of Medicare Part B carriers representing all 50 states and the District of Columbia from 2005 to 2009, we calculated the Medicare payment-service volume elasticities for noncomplex (CPT 66984) and complex (CPT 66982) cataract surgeries. DATA EXTRACTION Service volume data were extracted from the CMS Part B National Summary and Carrier Summary Data Files. Payment data were extracted from the Medicare Physician Fee Schedule. PRINCIPAL FINDINGS From 2005 to 2009, the proportion of total cataract services billed as complex increased from 3.2 to 6.7 percent. Every 1 percent decrease in Medicare payment was associated with a nonsignificant change in noncomplex cataract service volume (elasticity = 0.15, 95 percent CI [-0.09, 0.38]) but a statistically significant increase in complex cataract service volume (elasticity = -1.12, 95 percent CI [-1.60, -0.63]). CONCLUSIONS Reduced Medicare payment was associated with a significant increase in complex cataract service volume but not in noncomplex cataract service volume, resulting in a shift toward performing a greater proportion of complex cataract surgeries from 2005 to 2009.

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.

Intraoperative floppy-iris syndrome associated with use of antipsychotic drugs. Can J Ophthalmol 2016; 51:294-296. [PMID: 27521670 DOI: 10.1016/j.jcjo.2016.02.008] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2015] [Revised: 11/24/2015] [Accepted: 02/16/2016] [Indexed: 11/20/2022]
Abstract
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. In case 2, a 63-year-old woman with schizophrenia had used aripiprazole, quetiapine, and risperidone for more than 10 years. In case 3, a 65-year-old woman with an organic mental disorder had used haloperidol for more than 10 years. At least 5 cases of antipsychotic drug-induced IFIS have been reported in the literature. CONCLUSIONS Any class of antipsychotic drugs can cause IFIS. Although antipsychotic drug-induced IFIS can be mild, surgeons should be alert to the possibility of IFIS when they treat patients with current and past use of antipsychotic drugs.

Abstract
Purpose: To customize clinical practice guidelines (CPGs) for cataract management in the Iranian population. Methods: First, four CPGs (American Academy of Ophthalmology 2006 and 2011, Royal College of Ophthalmologists 2010, and Canadian Ophthalmological Society 2008) were selected from a number of available CPGs in the literature for cataract management. All recommendations of these guidelines, together with their references, were studied. Each recommendation was summarized in 4 tables. The first table showed the recommendation itself in clinical question components format along with its level of evidence. The second table contained structured abstracts of supporting articles related to the clinical question with their levels of evidence. The third table included the customized recommendation of the internal group respecting its clinical advantage, cost, and complications. In the fourth table, the internal group their recommendations from 1 to 9 based on the customizing capability of the recommendation (applicability, acceptability, external validity). Finally, customized recommendations were sent one month prior to a consensus session to faculty members of all universities across the country asking for their comments on recommendations. Results: The agreed recommendations were accepted as conclusive while those with no agreement were discussed at the consensus session. Finally, all customized recommendations were codified as 80 recommendations along with their sources and levels of evidence for the Iranian population. Conclusion: Customization of CPGs for management of adult cataract for the Iranian population seems to be useful for standardization of referral, diagnosis and treatment of patients.

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.
