Summary: This study analyzed tear proteome profiles before and after treatments in patients with Keratoconus to identify biomarkers altered by surgery. The results revealed dysregulated proteins in KC patients, with cytoskeleton-related processes being the most affected when comparing different treatment groups.

Summary: The study evaluated the long-term effectiveness, safety, and stability of Ferrara-type ICRS implantation by manual surgery in patients with keratoconus. The surgery significantly improved visual acuity, refractive error, and topographic values, and the improvement remained stable throughout a 5-year follow-up period. The procedure was deemed stable regardless of the patient's age, showing no regression in any visual or topographic parameter over time.

Summary: The purpose of this study was to investigate the effects of intracorneal ring segments (ICRSs) on visual outcomes and epithelial remodeling in patients with duck-type keratoconus. The results showed that ICRS implantation significantly improved corrected and uncorrected distance visual acuity, and induced epithelial thickening along the segment. The study concluded that ICRS implantation can effectively manage duck-type keratoconus.

Summary: This study compared the five-year outcomes of two complete intracorneal implants (MyoRing and annular-shaped intracorneal implant [AICI]) combined with accelerated corneal cross-linking (A-CXL) in progressive keratoconus (KCN). The results showed that both AICI plus A-CXL and MyoRing plus A-CXL groups had similar pre- and postoperative visual, refractive, tomographic, biomechanical, and aberrometric parameters. After five years, MyoRing plus A-CXL group had significant improvements in anterior corneal surface (ACS) flat-K and corneal thickness, while AICI plus A-CXL group had significant improvements in ACS K-max and mean-K values. Both groups showed significant improvements in ACS steep-K and corneal astigmatism. Additionally, the AICI group had significantly better high order aberration compared to the MyoRing group. In conclusion, both MyoRing and AICI combined with A-CXL can significantly improve visual, refractive, and corneal aberrometric, biomechanical, and tomographic parameters and effectively halt the progression of KCN with comparable long-term outcomes.

Summary: The purpose of this study was to evaluate the effects of intrastromal corneal ring segments (ICRS) that were explanted due to late extrusion on keratoconic corneas. The results showed that after explantation, the corneal topographic findings nearly returned to the baseline level, but there was a significant worsening in refractive cylinder. The main factors before implantation included keratoconus grade, keratometric readings, and visual acuities, while the main factors after ICRS implantation were refractive cylinder, corrected distance visual acuity, and uncorrected distance visual acuity. Corneal aberrations played an important role in the pre-explantation analysis.

Summary: Confirming the progression of keratoconus is crucial for proper treatment, and it should exceed the variability of corneal monitoring devices to be considered real change. This study aimed to evaluate the repeatability and reproducibility of a Scheimpflug camera in measuring corneal parameters in keratoconus and ICRS eyes. The results showed better precision and narrower limits of repeatability and reproducibility in keratoconus eyes compared to ICRS eyes. The cutoff values to determine genuine corneal shape change were different between keratoconus and ICRS eyes, and corneal tomography measurements were less accurate in ICRS eyes.

Summary: The study reviewed consecutive cases of intrastromal corneal ring segments explanted in the last 10 years to determine the main causes and define the incidence rate. Functional failure, particularly refractive failure, was found to be the main reason for explantation followed by anatomic failure, with spontaneous extrusion being a common issue in advanced cases of keratoconus.

Summary: A framework was used to map societal factors associated with ocular surface diseases, considering the individual, health, and environment. The impact of the COVID-19 pandemic and mitigating factors on ocular surface diseases were reviewed systematically. Age and sex effects are well-characterized for various types of ocular surface diseases. Sex and gender, genetic factors, race, smoking, and co-morbidities have interdependencies with geographical, employment, and socioeconomic factors. Living and working conditions, as well as regional and global socio-economic, cultural, and environmental conditions, play a role in the prevalence and severity of ocular surface diseases. Digital technology, conflicts, natural disasters, and the pandemic influence access to health services. The COVID-19 pandemic and related strategies have increased the risk of developing or worsening ocular surface diseases.

Summary: The ocular surface, consisting of the corneal and conjunctival epithelium, plays a crucial role in maintaining ocular integrity and function. Gene defects can lead to ocular surface disorders, either as congenital conditions or through the interaction of genetic and environmental factors. Advanced gene-based technologies have shown promise in disease modeling and gene therapy for monogenic ocular surface disorders. Understanding the genetic factors involved in both monogenic and multifactorial ocular surface disorders could pave the way for personalized disease models and treatment strategies.

Summary: Adaptive optics (AO) retinal imaging allows for the visualization of individual photoreceptors in a clinical setting, which is crucial for studying photoreceptor degeneration. AO imaging is a powerful clinical tool that can detect cellular-level degeneration that may be missed by traditional methods. It is also useful for early-stage diagnosis and monitoring disease progression. However, caution should be exercised when interpreting AO imaging results due to various factors that can affect image quality and normal values.

Summary: A comprehensive analysis of the Global Burden of Disease Study (GBD) 2019 revealed the disease burden and trends in Australia from 1990 to 2019. Non-communicable diseases remained the leading cause of mortality in Australia, with low back pain, depressive disorders, and other musculoskeletal diseases being the main contributors to disability-adjusted life-years (DALYs). High BMI, smoking, high blood pressure, high fasting plasma glucose, and drug use were identified as the leading risk factors for DALYs. Australia's ranking improved for death rates and life expectancy, but not for years lived with disability (YLDs) and years of life lost (YLLs) compared to similar countries.

Summary: This study investigates the discordance between the adaptive optics (AO) montage center (AMC) and the foveal pit center (FPC) and its implications for cone mosaic analysis. The results show a marked mismatch between the AMC and FPC, which may be modified by diseases such as rod-cone dystrophy. The distance between AMC and FPC is a significant determinant of cone density and inter-cone distance.
