Aim: To evaluate the short-term effect of 0.15% sodium hyaluronate (SH), 0.20% SH, and Trehalose + 0.15% SH on anterior corneal aberrations in dry eye patients.
Methods: 76 eyes of 76 dry eye patients were divided into three groups. Non-preserved 1.5 mg/mL SH was administered in group 1, non-preserved 2.0 mg/mL SH was administered in group 2, and non-preserved trehalose 30 mg/mL and 1.5 mg/mL SH was administered in group 3. Aberrometry measurements were performed before and 10 min after application of the artificial tear drop. Using the Pentacam Scheimpflug imaging system, total root mean square (RMS), lower-order aberration (LOA), higher-order aberrations (HOAs), spherical aberration (SA), trefoil, and coma aberrations were investigated.
Results: In each group; the RMS of total, LOA, HOAs, and spherical aberration were significantly decreased after the artificial drop instillation, compared with those of them at baseline; and in groups 1 and 2, vertical trefoil term was also significantly increased, compared with those of them at baseline. According to intergroup analyzes, there was no significant outcome.
Conclusions: It was observed that three artificial tears reduced the anterior corneal aberrations, in a 10-min period. The short-term effect of three artificial tears on the anterior corneal aberration was similar.

Department of Regeneration and Cell Therapy, Andalusian Molecular Biology and Regenerative Medicine Centre (CABIMER), Avda. Américo Vespucio 24, 41092 Seville, Spain.
Purpose: To evaluate the role of contact lenses (CLs) in visual rehabilitation following keratoplasty.
Methods: Four databases, including PubMed, Scopus, Web of Science, and Embase were systematically searched for studies published between January 2010 and July 2023. Visual outcomes, daily wearing duration, subjective comfort, rate and etiology of CL discontinuation, corneal endothelial cell density, central corneal thickness, and complications were extracted.

Lipid nanoparticles (LNPs) have shown great potential in the field of gene therapy for retinal diseases. To expand on this application, we investigated LNP-mediated mRNA delivery to the anterior chamber of the eye via the intracameral (IC) route of administration. Here, we show that IC injections of LNPs facilitated protein expression and gene editing in the trabecular meshwork (TM).

Epidemic keratoconjunctivitis (EKC) is one of the most severe clinical manifestations of human adenovirus ocular surface infection, which may lead to the formation of subepithelial infiltrates (SEIs) in the anterior corneal stroma in 20-50 % of cases. SEIs may be asymptomatic or give rise to corneal aberrations and visual impairment for months or years after acute infection, despite treatments. Here, we describe the ultrastructural and immunophenotypic features of the anterior corneal stroma of a patient who underwent superficial anterior lamellar keratoplasty (SALK) surgery to remove corneal opacities related to clinically significant and steroid-unresponsive, long-lasting SEIs after adenoviral EKC.

Approximately 3% of individuals in road traffic accidents suffer ocular injuries. We present a case of a man in his late 80s who presented with bilateral corneal decompensation following airbag deployment during a road traffic accident. Ocular examination revealed multilevel ocular injury with severe bilateral corneal oedema.

Mutations in genes that initiate and regulate the complex pathways involved in eye development can cause a spectrum of disorders such as ASD, congenital cataracts and corneal opacity. In South Africa, causes of ASD are poorly understood with few studies looking at the possible genetic basis for these disorders.
