Purpose To evaluate in a large sample of patients from 10 different European centers the results of cataract surgery, characterizing the relationship between patient-reported outcomes (PROMs) and clinician-reported outcome measures (CROMs). Methods Prospective non-interventional multicenter observational descriptive study analyzing the clinical outcomes of a total of 3799 cases undergoing cataract surgery (mean age: 72.7 years). In all cases, the cataract surgery standard developed by the International Consortium for Health Outcomes Measurements (ICHOM) was used to register the clinical data. Three-month postoperative visual acuity and refraction data were considered CROMs, whereas Rasch-calibrated item 2 (RCCQ2) and total Catquest-9SF score (CQ) were considered PROMs. Results Postoperative corrected distance visual acuity (CDVA) was 0.3 logMAR or better in 88.7% (2505/2823) of eyes. Mean differences between preoperative and postoperative RCCQ2 and CQ scores were −3.09 and −2.39, respectively. Visual function improvement with surgery was reported by 91.5% (2163/2364) of patients. Statistically significant, although weak, correlations of postoperative CDVA with postoperative refraction, PROMs, and complications were found (0.133 ≤ r ≤0.289, p < 0.001). A predictive model (R2: 0.254) of postoperative CDVA considering 10 variables was obtained, including preoperative CDVA, different ocular comorbidities, age, gender and intraoperative complications. Likewise, another predictive model (R2: 0.148) of postoperative CQ considering a total of 14 variables was obtained, including additionally preoperative CQ, target refraction and previous surgeries. Conclusions Cataract surgery provides an improved functional vision in most of patients although this improvement can be limited by ocular comorbidities and complications. The relationship between PROMs and CROMs is multifactorial and complex. This study has been sponsored by a grant from Johnson & Johnson Vision.

This study focuses on the synthetic approach influence in morphostructural features and catalytic performances for Ni/CeO2 catalysts. Incipient wetness impregnation, coprecipitation and nitrate combustion were studied as catalyst preparation approaches, and the materials were then tested at 700 °C for methane dry reforming (MDR). The morphostructural properties of the materials were deeply studied using several techniques, such as temperature programmed reduction (TPR), to investigate reducibility and support-metal interaction, N2 physisorption to evaluate the porosity and the surface area, scanning electron microscopy (SEM) and X-ray diffraction (XRD) to estimate Ni dispersion, and temperature programmed oxidation (TPO) to identify the type and amount of coke formed on catalysts’ surface after reaction. From the data obtained, coprecipitation turned out to be the most suitable technique for this application because this catalyst was able to reach 70% of CO2 conversion and 30% methane conversion, with an H2 yield of 15% and 30% yield of CO at the end of the 30 h test. Moreover, it was also the catalyst with the highest metal dispersion, the strongest interaction with the support, and the lowest coke deposition.

Purpose: Implementation of the International Consortium for Health Outcomes Measurements (ICHOM) standard for cataract surgery into clinical practice at an Italian tertiary referral centre. Methods: Prospective, observational, descriptive study consisting of the registry and analysis of cataract surgeries performed during a 6-month enrolment period at the University Eye Clinic of Trieste, Trieste, Italy. Outcomes were recorded and analysed according to the ICHOM Cataract Standard Set version 2.0.1. Records included clinician-reported outcome measures (CROMs) – visual outcome and complications – and patient-reported outcome measures (PROMs) – self-assessed vision with the Catquest-9SF questionnaire. Correlations between PROMs and CROMs were evaluated. A multiple linear regression was used for predicting the change in PROMs with surgery. Results: A total of 218 eyes (of 218 patients) were analysed. Postoperative corrected distance visual acuity (CDVA) was ⩾0.3 in 89.0% (194/218) of eyes. There was a statistically significant improvement of the post-operative Catquest-9SF global average score. ( p 2: 0.527) based on preoperative Catquest-9SF total score, presence or not of macular degeneration, presence or not of intraoperative complications, age >75 years old, and preoperative CDVA. Conclusions: Cataract surgery improves the functional vision, with some factors limiting the outcomes such as comorbidities. Self-perceived improvement in intermediate vision significantly influenced the improvement in self-assessed vision.
