Purpose: To evaluate the clinical and patient-reported outcomes of the toric version of a refractive extended depth of focus intraocular lens (IOL).
Methods: This was a prospective observational study including 26 eyes of 26 patients (age range: 58 to 88 years) who underwent cataract surgery with implantation of the LuxSmart toric IOL (Bausch & Lomb GmbH). Changes in distance, intermediate (80 cm), and near (40 cm) visual acuities, manifest refraction, defocus curve, distance photopic contrast sensitivity (CSV-1000 test), and patient-reported outcomes (Catquest-9SF questionnaire) were evaluated during a 3-month follow-up.
Results: Mean 3-month postoperative uncorrected distance, corrected distance, distance-corrected intermediate, and distance-corrected near visual acuities of 0.10 ± 0.11, 0.03 ± 0.08, 0.06 ± 0.13, and 0.38 ± 0.22 logarithm of the minimum angle of resolution (logMAR) were found, respectively. Uncorrected and corrected distance visual acuity improved significantly with surgery ( < .001). In the defocus curve, mean visual acuity was 0.30 logMAR or better for defocus between +0.50 and -2.00 D, without significant changes during the follow-up ( ⩾ .071). The postoperative spherical equivalent was within ±0.50 and ±1.00 diopters (D) in 92% and 96% of eyes, respectively. Surgically induced astigmatism prediction error ranged between -0.37 and 0.80 D, with a mean value of 0.11 ± 0.28 D. Mean 3-month postoperative contrast sensitivity was within or close to the upper limit of the normality range for most spatial frequencies. Mean 3-month postoperative overall Rasch calibrated Catquest score was -1.68 ± 1.04, with 96.2% of patients satisfied with the vision achieved. IOL rotations of 5º or less were observed in 92.3% of eyes.
Conclusions: The toric extended depth of focus IOL evaluated provides a good distance and intermediate functional vision in eyes with preexisting corneal astigmatism, with functional near visual performance for most patients. .

The design of highly efficient photocatalysts to photoreduce nitrogen (N) to ammonia (NH) under mild conditions is extremely challenging. In this work, various molar ratio of molybdenum (Mo) is incorporated into BiOCl via a hydrothermal process. The resulting Mo-doped BiOCl exhibits remarkable solar-driven activity for N photo fixation without any scavengers or sacrificial agents.

ObjectiveAim of this study was to evaluate the 24 months follow-up data of the German Cartilage Registry (KnorpelRegister DGOU, GCR) regarding the influence of body mass index (BMI) on clinical outcomes after surgical osteochondral lesions of the talus (OCT) treatment.DesignA total of 303 patients met the inclusion criteria. Pre- and post-operative Foot and Ankle Outcome Score (FAOS) total scores, subscores, and ΔFAOS were analyzed for most frequent surgical techniques (bone marrow stimulation [BMS], matrix-augmented BMS, matrix-augmented BMS with additional bone grafting) in normal weight group (NW, BMI <30 kg/m, = 228) and obese weight group (OW, BMI ≥30 kg/m, = 75).

Introduction: Australians living in isolated communities are more likely to experience poorer health outcomes as a result of rurality. This article provides a needs assessment of healthcare services in a geographically isolated region of Victoria, Australia.
Methods: The research project employed a mixed-methods design.
While most recent autonomous driving system focuses on developing perception methods on ego-vehicle sensors, people tend to overlook an alternative approach to leverage intelligent roadside cameras to extend the perception ability beyond the visual range. We discover that the state-of-the-art vision-centric detection methods perform poorly on roadside cameras. This is because these methods mainly focus on recovering the depth regarding the camera center, where the depth difference between the car and the ground quickly shrinks while the distance increases.
