Keratoconus detection with a focus on new indices and techniques
Early and accurate detection of Keratoconus (KC) provides opportunities to address adverse visual consequences, reduces the likelihood of keratoplasty, and offers collagen crosslinking (CXL) as a treatment to potentially slow progression [1]. (Source: Contact Lens and Anterior Eye)

Presbyopia correction with multifocal contact lenses: Evaluation of silent reading performance using eye movements analysis
Many activities of daily living rely on reading, thus is not surprising that complaints from presbyopes originate in reading difficulties rather in visual acuity. Here, the effectiveness of presbyopia correction with multifocal contact lenses (CLs) is evaluated using an eye-fixation based method of silent reading performance.

Long-term effects of tear film component deposition on the surface and optical properties of two different orthokeratology lenses
The prevalence of myopia is increasing worldwide, and the condition is predicted to affect almost half of the world ’s population by 2050 [1]. To treat myopia, most commonly, a person may wear single-vision spectacles or contact lenses daily, or a surgical treatment such as refractive surgery may be applied [2]. Many people choose to wear contact lenses for the convenience they provide when participating in spo rts or outdoor activities. Orthokeratology (ortho-k) lenses are an alternative option that reshape the anterior cornea with a reverse geometry design; by wearing them overnight, patients can temporarily have norma...

Tear-film evaporation flux and its relationship to tear properties in symptomatic and asymptomatic soft-contact-lens wearers
With soft-contact-lens wear, evaporation of the pre-lens tear film affects the osmolarity of the post-lens tear film and this can introduce a hyperosmotic environment at the corneal epithelium, leading to discomfort. The purposes of the study are to ascertain whether there are differences in evaporation flux (i.e., the evaporation rate per unit area) between symptomatic and asymptomatic soft-contact-lens wearers, to assess the repeatability of a flow evaporimeter, and to assess the relationship between evaporation fluxes, tear properties, and environmental conditions.

Diagnosis and treatment of Acanthamoeba Keratitis: A scoping review demonstrating unfavorable outcomes
Acanthamoeba spp. are pathogens that cause Acanthamoeba keratitis (AK), a serious cornea inflammation that can lead to gradual loss of vision, permanent blindness, and keratoplasty. The efficacy of AK treatment depends on the drug ’s ability to reach the target tissue by escaping the protective eye barrier. No single drug can eradicate the living forms of the amoeba and be non-toxic to the cornea tissue. The treatment aims to eradicate both forms of protozoan life but is hampered by the resistance of the cysts to the most a vailable drugs, leading to prolonged infection and relapses.
