Anatomical and physiological considerations in scleral lens wear: Eyelids and tear film
Scleral lenses can affect a range of anterior segment structures including the eyelids and the tears. The eyelids, consisting of the outer skin layer, the middle tarsal plate, and the posterior palpebral conjunctiva, provide physical protection and house the meibomian glands and cilia which have important and unique functions. Tears consist of a mix of aqueous, mucus, and lipidomic components that serve vital functions of lubricity, protection, and nourishment to the ocular surface. Both the eyelids and the tear film interact directly with scleral lenses on the eye and can affect but also be impacted by scleral lens wear. ...

Non-contact specular microscopy with Topcon instruments to assess central corneal thickness of healthy human eyes – A 20 year review
In the 1960 ’s it became progressively recognized that objective measures using optical pachymetry were useful in the assessment of post-operative corneal edema, with it being considered that these had high ‘sensitivity (accuracy of 0.01 mm)’ [1]. The pachymetry measures could be made by viewing the cor nea in specular reflection mode with the slitlamp, with an attachment available to facilitate setting of the correct angle for illumination and observation to make central corneal thickness (CCT) measurements.

Adaptation and adverse responses to contact lens wear
The Contact Lens and Anterior Eye journal continues with this now successful and established tradition of the first issue having a theme. This year it is on adaptation and adverse responses to contact lens wear. Contact lens practitioners are responsible for continuous monitoring of contact lens wear with clinical investigations to determine any short and long term changes to the cornea and ocular surface. The arrival of silicone hydrogel contact lenses more than two decades ago had significantly reduced several complications related to ocular surface hypoxia. (Source: Contact Lens and Anterior Eye)

Bibliometric analysis of the orthokeratology literature
The wearing of rigid lenses can result in changes to corneal curvature and the planned, temporary reduction of myopia by wearing flat-fitting rigid lenses (termed orthokeratology) was first reported in the 1960 ’s [1]. In the late 1970’s and early 1980’s, several studies evaluated this concept and concluded that the reduction in myopia was relatively short-lived, unpredictable, inconsistent and limited to only a low degree of myopia; as such, orthokeratology was largely ignored at this time [2–4].

Outcome, influence factor and development of CLS measurement in continuous IOP monitoring: A narrative review
A large fluctuation in intraocular pressure (IOP) and a high peak IOP remain the risk factors for progressive visual field loss in patients with glaucoma, which is a leading cause of irreversible blindness. However, IOP measurements during working time cannot provide sufficient information on IOP to guide clinicians in setting IOP target values. Contact lenses are extensively used in ophthalmology to correct the refractive error, and recently, they are serving as platforms for detection and drug delivery.
