RESUMEN
INTRODUCTION: The aim of this study was to evaluate the effect of initial treatment regimen individualization (pro re nata or treat-and-extend [TAE]), according to macular neovascularization (MNV) subtype, on the functional and anatomical response in neovascular age-related macular degeneration (nAMD). The secondary objective was to compare the treatment burden between each MNV subtype. METHODS: Consecutive treatment-naïve nAMD patients were retrospectively included. MNV subtype was graded by 2 independent blinded investigators on multimodal imaging. Functional and anatomical outcomes were analysed according to treatment regimen and MNV subtypes. RESULTS: A total of 281 eyes from 243 patients were included in the study. According to the treatment regimen, there was no significant difference in best-corrected visual acuity gain within the first 2 years of treatment for type 1 (p = 0.106) and type 3 MNV (p = 0.704). Conversely, there was a significant difference in favour of TAE regimen for type 2 (p = 0.017) and type 4 MNV (p = 0.047). Type 1 MNV had a higher proportion of visits with subretinal fluid (p = 0.0007) but not with intraretinal fluid (p = 0.22). The mean interval between the last 2 injections was significantly shorter for type 1 MNV (p = 0.0045). CONCLUSION: The individualization of the initial treatment protocol according to MNV subtype can improve the functional outcome and may decrease the treatment burden.

OBJECTIVES: To evaluate the utility of the SPOT scleral lens (Oxygen Permeable Scleral Lens of Thonon; LAO, Thonon-les-Bains, France) in the management of the irregular cornea after refractive surgery. METHOD: We included 19 patients (35 eyes) with irregular corneas after refractive surgery. Patients were fitted with scleral lenses after the failure of conventional contact lenses adaptation. The ophthalmologic examination included measurement of best-corrected visual acuity (BCVA), slitlamp examination, and evaluation of ocular aberrations (Objective Scattering Index [OSI] and higher-order aberration [HOA]). RESULT: Scleral lens fitting increases significantly the BCVA from 0.33 (±0.25) to 0.08 (±0.13) LogMAR (P<0.001). There was also a significant decrease in Ocular Surface Disease Index from 66.2±22.8 to 42.4±18.9 (P<0.001). Ocular aberrations (OAs) are also significantly reduced by the scleral lenses, the mean OSI goes from 7.2 (±4.2) to 3.0 (±1.8) (P<0.001), OA from 2.58 (±1.34) to 1.98 µm (±2.31) (P=0.035), and HOA from 0.94 (±0.51) to 0.48 (±0.23) (P=0.0018). CONCLUSION: Fitting with scleral lenses improves patients' optical and ocular surface problems. Scleral lens restores BCVA and the quality of life. Fitting with scleral lenses is an alternative to further surgery on these fragile eyes and is sometimes the only viable treatment option for the patient.

OBJECTIVE: To determine the ophthalmological and extra-ophthalmological clinical characteristics and visual prognosis of patients with sarcoid uveitis in different ethnic groups. METHODS: We retrospectively analysed the data from patients with sarcoid uveitis seen at two departments of Ophthalmology between December 2003 and December 2017. Patients presented biopsy-proven sarcoidosis and/or presumed sarcoid uveitis based on the following criteria: compatible thoracic imaging, associated with elevated angiotensin-conversion enzyme (ACE) and/or lymphocytic alveolitis on bronchoalveolar lavage fluid analysis (> 15% lymphocytes and CD4/CD8 > 3.5). Ophthalmological and general characteristics, as well as visual and global prognoses, were compared in three pre-defined ethnic groups: White Europeans, North Africans and Afro-Caribbeans. RESULTS: A total of 194 patients were included: 145 with biopsy-proven and 49 with presumed sarcoid uveitis. Overall, 68% were White Europeans while 20.6% were North Africans and 11.3% were Afro-Caribbeans. Sixty-nine per cent were women and the median age at presentation was 52.1 years. Median ages at first ocular manifestation of the disease in Afro-Caribbeans and North Africans were respectively 34.3 and 43.1 years, while it was 57.8 years in White Europeans (p < 0.001). Ocular involvement was bilateral in 77.8% (n = 151) of the cases and nearly half of the patients had panuveitis (48.5%). Anterior uveitis was more frequent in Afro-Caribbeans (59.1%; p < 0.0001), while White Europeans presented more frequently with intermediate uveitis. There was a significantly higher frequency of systemic involvement of sarcoidosis in North Africans while White Europeans showed a higher frequency of isolated ocular involvement at onset and during follow-up. Afro-Caribbeans, who had a complete visual recovery in 72.7% of the cases, had a better visual prognosis than other ethnic groups (p = 0.025). CONCLUSION: In this large European series of sarcoid uveitis, we observed ethnicity-related differences regarding uveitis clinical presentation and visual outcome. Although good overall, the visual prognosis seems to be better in Afro-Caribbeans than in other ethnic groups.

BACKGROUND: Clostridium difficile infection (CDI) is a serious medical condition that is associated with substantial morbidity and mortality. Identification of risk factors associated with CDI and prompt recognition of patients at risk is key to successfully preventing CDI. METHODS: A 3-year prospective, observational, cohort study was conducted in a French university hospital and a nested case-control study was performed to identify risk factors for CDI. Inpatients aged 18 years or older, suffering from diarrhea suspected to be related to CDI, were asked to participate. RESULTS: A total of 945 patients were included, of which 233 cases had a confirmed CDI. CDI infection was more common in men (58.4%) (P = 0.04) compared with patients with diarrhea not related to C. difficile. Previous hospitalization (P < 0.001), prior treatment with antibiotics (P = 0.001) or antiperistaltics (P = 0.002), liver disease (P = 0.003), malnutrition (P < 0.001), and previous CDI (P < 0.001) were significantly more common in patients with CDI. Multivariate logistic regression analysis showed that exposure to antibiotics in the last 60 days (especially third generation cephalosporins and penicillins with ß-lactamase inhibitor), chronic renal or liver disease, malnutrition or previous CDI, were associated with an independent high risk of CDI. Age was not related with CDI. CONCLUSIONS: This study showed that antibiotics and some comorbid conditions were predictors of CDI. Patients at high risk of acquiring CDI at the time of admission may benefit from careful monitoring of antibiotic prescriptions and early attention to infection control issues. In future, these "high-risk" patients may benefit from novel agents being developed to prevent CDI.

Descemet Membrane Endothelial Keratoplasty (DMEK) selectively replaces the damaged posterior part of the cornea. However, the DMEK technique relies on a manually-performed dissection that is time-consuming, requires training and presents a potential risk of endothelial graft damages leading to surgery postponement when performed by surgeons in the operative room. To validate precut corneal tissue preparation for DMEK provided by a cornea bank in order to supply a quality and security precut endothelial tissue. The protocol was a technology transfer from the Netherlands Institute for Innovative Ocular Surgery (NIIOS) to Lyon Cornea Bank, after formation in NIIOS to the DMEK "no touch" dissection technique. The technique has been validated in selected conditions (materials, microscope) and after a learning curve, cornea bank technicians prepared endothelial tissue for DMEK. Endothelial cells densities (ECD) were evaluated before and after preparation, after storage and transport to the surgery room. Microbiological and histological controls have been done. Twenty corneas were manually dissected; 18 without tears. Nineteen endothelial grafts formed a double roll. The ECD loss after cutting was 3.3 % (n = 19). After transportation 7 days later, we found an ECD loss of 25 % (n = 12). Three days after cutting and transportation, we found 2.1 % of ECD loss (n = 7). Histology found an endothelial cells monolayer lying on Descemet membrane. The mean thickness was 12 ± 2.2 µm (n = 4). No microbial contamination was found (n = 19). Endothelial roll stability has been validated at 3 days in our cornea bank. Cornea bank technicians trained can deliver to surgeons an ECD controlled, safety and ready to use endothelial tissue, for DMEK by "no touch" technique, allowing time saving, quality and security for surgeons.

BACKGROUND: The emergency department has been identified as an area within the health care sector with the highest reports of violence. The best way to control violence is to prevent it before it becomes an issue. Ideally, to prevent violent episodes we should eliminate all triggers of frustration and violence. Our study aims to assess the impact of a quality improvement multi-faceted program aiming at preventing incivility and violence against healthcare professionals working at the ophthalmological emergency department of a teaching hospital. METHODS/DESIGN: This study is a single-center prospective, controlled time-series study with an alternate-month design. The prevention program is based on the successive implementation of five complementary interventions: a) an organizational approach with a standardized triage algorithm and patient waiting number screen, b) an environmental approach with clear signage of the premises, c) an educational approach with informational videos for patients and accompanying persons in waiting rooms, d) a human approach with a mediator in waiting rooms and e) a security approach with surveillance cameras linked to the hospital security. The primary outcome is the rate of incivility or violence by patients, or those accompanying them against healthcare staff. All patients admitted to the ophthalmological emergency department, and those accompanying them, will be enrolled. In all, 45,260 patients will be included in over a 24-month period. The unit analysis will be the patient admitted to the emergency department. Data analysis will be blinded to allocation, but due to the nature of the intervention, physicians and patients will not be blinded. DISCUSSION: The strengths of this study include the active solicitation of event reporting, that this is a prospective study and that the study enables assessment of each of the interventions that make up the program. The challenge lies in identifying effective interventions, adapting them to the context of care in an emergency department, and thoroughly assessing their efficacy with a high level of proof.The study has been registered as a cRCT at clinicaltrials.gov (identifier: NCT02015884).

PURPOSE: To describe an unusual case of Whipple's disease (WD) complicated by uveitis, and subsequent paradoxical worsening after effective antibiotic treatment targeting Tropheryma whipplei (TW). METHODS: Case report. RESULTS: A 53-year-old male presented with bilateral knee arthritis, weight loss, chronic low-grade fever, and cognitive disorders. He was under treatment with tumor necrosis factor α inhibitors (TNFi) for seronegative spondyloarthritis. Given this unusual clinical presentation, further investigations were performed and revealed blood, saliva, stool, synovial fluid and cerebrospinal fluid positivity for TW, confirming the diagnosis of systemic WD. Ophthalmologic examination revealed bilateral posterior uveitis and an aqueous humor sample confirmed the presence of intraocular TW. TNFi were stopped, and the patient was subsequently treated with adequate antibiotics (ceftriaxone, followed by doxycycline and hydroxychloroquine), and subconjunctival corticosteroid injections. After a transient improvement of the ocular symptoms, he presented a recurrence of posterior segment inflammation, leading to repeated PCR testing for TW which were negative. Therefore, paradoxical worsening of the inflammation in the context of immune recovery uveitis (IRU) was thought to be the culprit. The patient was treated with systemic corticosteroid therapy, allowing for rapid improvement of the ocular findings. CONCLUSIONS: This case underlines the possibility of IRU complicating WD. Ophthalmologists, rheumatologists, and internists should be aware of this rare complication, particularly in the context of previous immunosuppressive therapy.
RESUMEN
PURPOSE: To assess the effectiveness of switching intravitreal dexamethasone implants (DEX-implant) from pro re nata (PRN) treatment regimen to a proactive regimen in patients with macular edema of diverse etiologies. DESIGN: An observational, retrospective, uncontrolled, multicenter, national case series. PARTICIPANTS: Eighty-one eyes from 68 patients treated between October 2015 and June 2023 were included. METHODS: This study included consecutive eyes treated with DEX-implant who were switched from a PRN regimen to a proactive regimen for diabetic macular edema (DME), retinal vein occlusion (RVO), noninfectious uveitis macular edema (UME; including postsurgical macular edema), and radiation maculopathy (RM). MAIN OUTCOME MEASURES: The main outcome measures were change in the best-corrected visual acuity (BCVA), central macular thickness (CMT), and intraocular pressure (IOP) at each visit. RESULTS: According to the etiology, DME represented 49.4% of eyes, UME 24.3%, RVO 21.0%, and RM 6.2%. The mean (standard deviation [SD]) duration of follow-up under the PRN and proactive regimens was 20.6 (13.3) and 14.2 (10.3) months, respectively. Switching from a PRN to a proactive regimen significantly improved mean (SD) BCVA by 3.7 (12.9) ETDRS letters (P = 0.01) with a mean (SD) decrease in CMT of 108.0 (151.4) µm (P < 0.001). The proportion of visits with significant anatomic recurrence (> 50 µm) also decreased from 40.1% to 6.0% after switching to a proactive regimen (P < 0.001). The number of DEX-implant injections significantly increased during the proactive treatment period (P < 0.001), but the change in the number of visits was not significantly different (P = 0.2). The proactive treatment period was not associated with a significant increase in IOP (P = 0.6). CONCLUSIONS: Switching to a proactive regimen in patients already treated with DEX-implant seems to significantly improve BCVA and CMT while maintaining stable IOP.

AIM: To assess the efficacy of focal photocoagulation of capillary macroaneurysms (CMA) to reduce the burden of intravitreal injections (IVI) in patients with macular edema (ME). MATERIALS AND METHODS: Retrospective multicenter study in patients with diabetic ME or ME secondary to retinal vein occlusion (ME-RVO). CMA associated with ME were selectively photocoagulated. Patients were followed for one year after photocoagulation. RESULTS: 93 eyes of 76 patients were included in this study. At 6 months after the laser (n = 93), there was a significant decrease in mean macular thickness (from 354 µm to 314 µm, p < 0.001) and in mean IVI number (from 2.52 to 1.52 at 6 months, p < 0.001). The mean BCVA remained stable (0.32 and 0.31 logMAR at baseline and 6 months, p = 0.95). At 12 months (n = 81/93), there was a significant decrease in mean macular thickness (from 354 µm to 314 µm, p < 0.001) and in mean IVI number (from 4.44 to 2.95 at 12 months, p < 0.001), while the mean BCVA remained stable (0.32 and 0.30 logMAR at baseline and 12 months, p = 0.16). CONCLUSION: Focal laser photocoagulation of CMA seems to be effective and safe for reducing the burden of IVI in patients with ME. Their screening during the follow-up should be considered closely.
RESUMEN
INTRODUCTION: Keratoconus has a significant impact on patients' quality of life (QoL), from diagnosis to the advanced stages of the disease. The aim of this research was to identify domains of QoL affected by this disease and its treatment. METHODS: Phone interviews were conducted using a semi-structured interview guide, with patients with keratoconus stratified according to their current treatment. A board of keratoconus experts helped identify the guide's main themes. RESULTS: Thirty-five patients (rigid contact lenses, n = 9; cross-linking, n = 9; corneal ring implants, n = 8; and corneal transplantation, n = 9) were interviewed by qualitative researchers. Phone interviews revealed several QoL domains affected by the disease and its treatments: "psychological", "social life", "professional life", "financial costs" and "student life". All domains were impacted, independently of the treatment history. Few differences were found between treatment regimens and keratoconus stages. Qualitative analysis enabled the development of a conceptual framework based on Wilson and Cleary's model for patient outcomes common to all patients. This conceptual model describes the relationship between patients' characteristics, their symptoms, their environment, their functional visual impairment and the impact on their QoL. CONCLUSIONS: These qualitative findings supported the generation of a questionnaire to evaluate the impact of keratoconus and its treatment on patients' QoL. Cognitive debriefings confirmed its content validity. The questionnaire is applicable for all stages of keratoconus and treatments and may help tracking change over time in regular clinical settings. Psychometric validation is yet to be performed before its use in research and clinical practices.
RESUMEN
Stevens-Johnson Syndrome (SJS) and toxic epidermal necrolysis (TEN) are serious and rare diseases, most often drug-induced, and their incidence has been estimated at 6 cases/million/year in France. SJS and TEN belong to the same spectrum of disease known as epidermal necrolysis (EN). They are characterized by more or less extensive epidermal detachment, associated with mucous membrane involvement, and may be complicated during the acute phase by fatal multiorgan failure. SJS and TEN can lead to severe ophthalmologic sequelae. There are no recommendations for ocular management during the chronic phase. We conducted a national audit of current practice in the 11 sites of the French reference center for toxic bullous dermatoses and a review of the literature to establish therapeutic consensus guidelines. Ophthalmologists and dermatologists from the French reference center for epidermal necrolysis were asked to complete a questionnaire on management practices in the chronic phase of SJS/TEN. The survey focused on the presence of a referent ophthalmologist at the center, the use of local treatments (artificial tears, corticosteroid eye drops, antibiotic-corticosteroids, antiseptics, vitamin A ointment (VA), cyclosporine, tacrolimus), the management of trichiatic eyelashes, meibomian dysfunction, symblepharons, and corneal neovascularization, as well as the contactologic solutions implemented. Eleven ophthalmologists and 9 dermatologists from 9 of the 11 centers responded to the questionnaire. Based on questionnaire results, 10/11 ophthalmologists systematically prescribed preservative-free artificial tears, and 11/11 administered VA. Antiseptic or antibiotic eye drops or antibiotic-corticosteroid eye drops were recommended as needed by 8/11 and 7/11 ophthalmologists, respectively. In case of chronic inflammation, topical cyclosporine was consistently proposed by 11/11 ophthalmologists. The removal of trichiatic eyelashes was mainly performed by 10/11 ophthalmologists. Patients were referred to a reference center for fitting of scleral lenses (10/10,100%). Based on this practice audit and literature review, we propose an evaluation form to facilitate ophthalmic data collection in the chronic phase of EN and we also propose an algorithm for the ophthalmologic management of ocular sequelae.

Background: The aim of this study was to describe the value of the Odysight® application in addition to a classical follow-up regimen in the detection of exudative recurrences in patients with macular edema. Methods: We conducted an observational, multicenter, retrospective study. The Odysight® application includes a visual acuity (VA) test that can lead to alerts in case of a drop of >5 VA letters on two successive tests. The efficacy of the alerts in detecting exudative recurrence was studied. Results: A total of 149 eyes of 123 patients were included. The sensitivity of alerts for the detection of recurrence was 30.8% (95% CI [17.6; 44.0]) and its specificity was 83.7% (95% CI [73.2; 94.3]. A better baseline VA was found to be significantly associated with a better retention of the application (OR = 0.05, 95% CI [0.002; 0.62]; p = 0.045). Of the 12/39 alerts that detected a recurrence, eight (20.5% of all alerts) resulted in the scheduling or advancement of an intravitreal injection. Conclusions: In the present study, the sensitivity and positive predictive value of the Odysight® application seems low but its use in addition to the usual follow-up of the patient can detect, in certain cases, an early recurrence and thus allow an anticipated readjustment of the treatment.
RESUMEN
PURPOSE: To evaluate the time required to complete a cataract training program for first-year ophthalmology residents using the EyeSi simulator. In addition, evaluate whether the simulator improves virtual performance of cataract surgery during the program. METHODS: We prospectively included first-year ophthalmology residents who had no experience of cataract surgery. The EyeSi simulator was used, and residents were able to follow the cataract training program, including course A (the easiest) through to course D (the hardest). In course B and above, a "cataract challenge" is proposed to the trainee every hour of simulation. RESULTS: A total of 24 participants were included in the study. During the study period, the mean (SD) total time spent on the surgical simulator was 815.6 (174.7) minutes. All the participants completed courses A and B within a mean (SD) of 366.7 (108.0) minutes. A total of 22 residents (91.7%) residents completed course C, and 5 (20.8%) course D. The mean (SD) best score on cataract challenge was 445.6/500 (40.2; range: 330-493) and was obtained in a mean (SD) 7.6 (2.6) attempts. All the residents obtained a score ≥ 60%. The best score in cataract challenge was not correlated to the time spent to achieve courses A and B (r = -0.37, p = 0.0726). CONCLUSIONS: The time required to complete a basic cataract training program is possible during the first-year residency. The scores obtained in the cataract challenge also increased during the training program and should lead to better surgery skills in these young ophthalmologists.
RESUMEN
PURPOSE: To identify multidimensional phenotypes of sarcoid uveitis patients. DESIGN: Retrospective cohort. METHODS: Consecutive patients with biopsy-proven, presumed, or probable sarcoid uveitis between December 2003 and December 2020 in Lyon were recruited. Data were collected from the clinical notes, and consisted in laboratory and imaging findings, systemic treatments and outcome. Systemic sarcoidosis was diagnosed according to the Abad's modified criteria and uveitis was classified according to the Standardization of Uveitis Nomenclature. A hierarchical cluster analysis was performed. The main outcome measure was identification of different phenotypes of sarcoid uveitis patients. RESULTS: A total of 299 patients were included. Three clusters were identified: (1) younger non-Caucasian patients who presented acute (75.3%), anterior (55.6%) uveitis, and systemic manifestations (87.8%), requiring oral corticosteroids (75.3%) along with immunosuppressive therapy (17.2%) and who were more prone to experience complete visual recovery (84.1%); (2) middle-aged Caucasian patients who presented chronic (91.7%), panuveitis (79.5%), and isolated uveitis at diagnosis (74.8%), requiring systemic treatment with corticosteroids (74.0%) but less frequently immunosuppressive therapy (9.8%) and a worse prognosis (45.3% complete visual recovery); and (3) middle-aged Caucasian patients, without preferential chronic or acute uveitis, isolated uveitis at diagnosis (81.4%), more homogenous in terms of eye involvement repartition, requiring less corticosteroids or immunosuppressive therapy (respectively 54.1% and 13.1%) and having a prognosis close to cluster 2 patients (55.3% complete visual recovery). CONCLUSIONS: This retrospective study suggested the existence of several phenotypes of sarcoid uveitis patients with different progressions and prognoses. Further studies are needed to determine the genetic and environmental factors that could explain these results.

Recently, concerns have been raised about an increased risk of cardiac sarcoidosis in patients with sarcoid uveitis. While cardiac sarcoidosis has a high mortality burden, there is still a lack of precise data on this association. The objective of this study is to describe the frequency and type of cardiac complications associated with sarcoidosis of a large cohort of patients with sarcoid uveitis. We analyzed the cardiac outcomes of a monocentric retrospective cohort of consecutive adults with a diagnosis of sarcoid uveitis between January 2004 and March 2020 in a tertiary French university hospital. A total of 294 patients with a final diagnosis of sarcoid uveitis were included. At final follow-up, seven (2.4%) patients of the cohort had cardiac sarcoidosis. Cardiac sarcoidosis was more frequent among patients with previously reported systemic sarcoidosis (p = 0.008). The prevalence of cardiac sarcoidosis among patients with sarcoid uveitis is low, but patients with previously diagnosed sarcoidosis or those who develop systemic sarcoidosis during follow-up appear to be at increased risk.
RESUMEN
PURPOSE: To evaluate the incidence of anterior chamber bacterial contamination during phacoemulsification cataract surgery using eubacterial polymerase chain reaction and conventional cultures. METHODS: This prospective study included 30 eyes of 24 patients who had phacoemulsification with implantation of a foldable acrylic posterior chamber intraocular lens through a 3.2-mm clear corneal incision. Topical aminosid was administered 3 days before surgery. After povidone-iodine antisepsis, 2 intraoperative anterior chamber aspirates were obtained from each patient, the first taken upon entering the anterior chamber and the second at the conclusion of surgery after the suture. Broad-range eubacterial polymerase chain reaction amplification and conventional cultures were used to verify that aqueous humor did not contain any detectable bacteria at the beginning of the surgery and to evaluate the bacterial contamination rate of the anterior chamber at the end of it. No oral antibiotic prophylaxis was used. RESULTS AND CONCLUSIONS: No specimens (0%) aspirated on entry into the anterior chamber or obtained at the conclusion of surgery were positive for microorganisms on culture or eubacterial polymerase chain reaction. None of the eyes developed acute endophthalmitis. The incidence of anterior chamber bacterial contamination during phacoemulsification recovered in this study using eubacterial polymerase chain reaction and conventional culture was null (0%).

BACKGROUND: Sarcoidosis is one of the leading causes of uveitis. To date, no studies have assessed the factors specifically related with recovery in ocular sarcoidosis. In this study, we aimed to determine factors associated with ocular and extraocular recovery in patients with sarcoid uveitis. METHODS: A retrospective study of sarcoid uveitis, with a three-year minimum follow-up in Lyon University Hospital between December 2003 and December 2019. Patients presented biopsy-proven sarcoidosis or presumed sarcoid. Recovery was defined by a disease-free status, spontaneously or despite being off all treatments for three years or more. RESULTS: 143 patients were included: 110 with biopsy-proven and 33 with presumed sarcoid uveitis. Seventy-one percent were women, the median age at presentation was 53 years, and 71% were Caucasian. Chronic uveitis was the main clinical presentation (75%), mostly panuveitis (48%) with bilateral involvement (82%). After a median follow-up of 83.5 months, recovery was reported in 26% of patients. In multivariable analysis, Caucasian ethnicity (p = 0.007) and anterior uveitis (p = 0.008) were significantly associated with recovery, while increased intraocular pressure was negatively associated (p = 0.039). CONCLUSION: In this large European cohort, one quarter of patients recovered. Caucasian ethnicity and anterior uveitis are associated with ocular and extraocular recovery.
RESUMEN
PURPOSE: Contact lens (CL)-related microbial keratitis (MK) has major public health implications, with about 300 million wearers worldwide, and certain potentially modifiable risk factors. This study aimed to identify the risk factors of CL-related MK. METHODS: A multicenter case-control study was conducted between 2014 and 2017. Cases presenting with CL-related MK were submitted to an anonymous 52-item questionnaire, which was also completed by healthy controls. Univariate followed by multivariate logistic regression analysis was performed. Risk factors for CL-related MK were given as odds ratio (OR) with 95% confidence interval and P-value. RESULTS: The study included a total of 2267 patients (1198 cases and 1069 controls). The MK risk factors for the daily disposable lenses group were exceeding the lens renewal period (OR = 9.16, P = 0.008) and occasionally wearing CL when sleeping (OR = 15.83, P = 0.035). The most important risk factors in the nondaily disposable lenses group were lens cleaning solution distributed by eye care brands (OR = 3.50, P < 0.001) and failure to renew lens cases (OR = 3.39, P = 0.001). Statistically and clinically significant variables were used to establish the MK risk equation for CL wearers, allowing an individual calculation of the risk of MK under lenses. CONCLUSIONS: The MK risk equation is a valuable tool for educating patients about the risks associated with wearing CL. It allows the patient to be informed about their overall risk of infection while detailing the precipitating elements of the infectious risk with the aim of modifying risk behavior.

PURPOSE: Iris intraocular implants were developed to manage congenital or traumatic iris defects. However, they are also used to change the color of patient eyes. The aim of this retrospective series was to report complications in patients managed in France after cosmetic implantation. SETTING: Ophthalmological institutions and private ophthalmologists in France. DESIGN: Multicenter retrospective observational study. METHODS: Questionnaires were sent to all ophthalmology departments in university hospitals and to private ophthalmologists. This questionnaire listed demographic and clinical data for each implanted eye with a focus on safety, the description of ocular complications (corneal edema, endothelial cell loss, increased intraocular pressure, and intraocular inflammation), and the therapeutic management implemented. RESULTS: Forty-four questionnaires (87 eyes) were collected, and ultimately, 33 questionnaires (65 eyes) were considered complete and analyzed. Two types of implants were identified. Of the 65 eyes analyzed, only 5 eyes (7.7%) did not experience any complication and 60 eyes (92.3%) had at least 1 complication. The most commonly reported complication was corneal decompensation (78.5%). The diagnosis of glaucoma was made in over half (52.3%) of the cases. Explantation was needed in 81.5% of cases. The mean final visual acuity was 0.45 ± 0.08 logarithm of the minimum angle of resolution (logMAR) (0 to 2 logMAR). CONCLUSIONS: Several ocular complications with a decreased mean visual acuity were described in a young healthy population. In addition, patient information on the safety of this procedure appeared insufficient.
