On the in vivo assessment of goblet cells of the human bulbar conjunctiva by confocal microscopy – A review
The human bulbar conjunctiva in healthy eyes is a non-stratified secretory epithelium that includes abundant numbers of goblet cells [1]. Goblet cells within the bulbar conjunctiva are therefore generally considered to be the major source of the mucus (mucin)-containing layer of the pre-corneal tear film, a layer that contributes to the stability of the tear film [2]. In histological examination by light microscopy of tissue sections, some of the goblet cells can be seen to be in contact with the conjunctival surface [1], and the actual openings at their apical ends onto the conjunctival surface can be viewed by scanning e...

Anterior segment optical coherence tomographic characterisation of keratic precipitates
Keratic precipitates (KPs) are an aggregate of inflammatory cells on the corneal endothelium [1]. They are found in multiple conditions, principally uveitis, but also in infectious keratitis [2] and corneal transplant rejection [1]. Different patterns have typically been ascribed to different conditions based on slit lamp examination findings, such as stellate KPs in Fuchs ’ heterochromic iridocyclitis [3] and “mutton fat” KPs in granulomatous uveitis [3].

Randomised controlled trial of corneal vs. scleral rigid gas permeable contact lenses for keratoconus and other ectatic corneal disorders
In cases of uncorrected regular and irregular astigmatism, the formation of an aqueous ‘lens’ in the post-lens tear film of rigid contact lenses neutralises 90 % of corneal astigmatism [1,2]. CoL bear on the cornea only, SL vault the cornea bearing entirely on the sclera, preventing detrimental mechanical interaction with the cornea [3]. CoL are considered the gold standard in the management of keratoconus [4]. Despite recent resurgence, SL use is limited to relatively few practitioners [3] managing advanced disease or as a problem solver for failed alternative contact lenses [5,6].

Clinical outcomes of a novel presbyopia-correcting soft contact lens with a small aperture
Presbyopia is an age-dependent condition wherein the eye loses its ability to accommodate. It begins to develop between 40 and 45 years of age, with the eye progressively failing to focus on near objects [1,2]. Considering the increased life expectancy and a gradual increase in the elderly population, interest in presbyopia correction has been growing [3]. (Source: Contact Lens and Anterior Eye)

Myopia control and contact lenses
Myopia is a global problem. The rising prevalence and the risks of sight ‐threatening ocular pathology associated with myopia are well documented [1,2]. By 2050, it is predicted that half of the world's population (five billion people) will have myopia, with nearly one billion at high risk of sight threatening ocular pathology such as myopic maculopathy, retinal detach ment and glaucoma. Those with a higher level of myopia being more susceptible to these ocular pathologies [1]. In some parts of the world myopia is now considered as a public health concern and as such it features on the World Health Organisation agenda [2...

Contrast sensitivity and visual acuity in subjects wearing multifocal contact lenses with high additions designed for myopia progression control
In most cases, myopia occurs due to excessive axial elongation of the eyeball. Nowadays, it is possible to correct vision even in cases of high myopia using various types of spectacles, contact lenses (CL) or refractive surgery. However, a significant concern related to myopia is the increased risk of ocular pathologies related to excessive eye growth, such as glaucoma, cataract, idiopathic retinal detachment or choroidal neovascularization [1]. In recent decades, the prevalence of myopia has increased dramatically worldwide [2 –4]. (Source: Contact Lens and Anterior Eye)

Innovative bulls eye drop applicator for self-instillation of eye drops
Management of many eye diseases depends on proper compliance of patients with the use of prescribed medication, which includes proper instillation of eye drops. The diseases include acute and chronic conditions including glaucoma, dry eyes and infectious keratitis which need long term use of topical eye drops [1,2]. Clinical outcome of any disease depends on proper and successful instillation of eye drops. Incorrect ways of putting drops may result in eye injury, abrasion, congestion of the eye, allergic skin reaction and also contamination of eye drops [3]. (Source: Contact Lens and Anterior Eye)

Light distortion of soft multifocal contact lenses with different pupil size and shape
The number of users of multifocal contact lenses has been rising due to the increasing popularity of these devices for presbyopic correction [1]. Most of the current multifocal designs are based on the principle of simultaneous image formation, in which multiple images are formed by different powered areas within the optic zone [2]. However, this principle can be associated with visual side effects, such as disability glare or haloes, especially when the pupil size increases, as in low illumination conditions.
