All soft contact lenses are not created equal
Soft contact lenses that have been prescribed by eye care practitioners are sometimes substituted for alternative lenses by unqualified, unregulated and sometimes even fully regulated lens suppliers, in the mistaken belief that there is essentially no difference between different soft lens types. This review considers the implications of inappropriately substituting soft contact lens types in terms of (a) lens properties: surface treatment, internal wetting agents, material, total diameter, back optic zone radius, thickness, edge profile, back surface design, optical design, power, colour (tint) and ultraviolet protection;...

Magnitude of astigmatism – A comparison between eyes
Astigmatism is a highly prevalent refractive error and while studies typically focus to describe the axis symmetry between eyes, little is known about the refractive symmetry. Therefore, this study determined the astigmatic power symmetry between eyes in a large clinic population. (Source: Contact Lens and Anterior Eye)

Reprising the Gothenburg Study
In this special issue of Contact Lens and Anterior Eye on the theme of “Long-term Effects of Contact Lens Wear”, the two surviving members of the original five authors of the celebrated “Gothenburg Study” [1] – NE and DS, the authors of the present paper – feel that it is apposite to reprise this work, which was published 37 years ago.

Scleral lens prescription and management practices: Emerging consensus
Prescription and management practices for scleral lenses have been studied through both single-center retrospective reviews [1 –6] and survey research [7,8]. Although useful, both approaches have limitations for understanding how scleral lenses are being prescribed. Specifically, single-center studies tend to reflect the fitting philosophy and prescription patterns preferred by a single practitioner or a relatively small group of practitioners. Findings from such research may be difficult to extrapolate to a broader population. (Source: Contact Lens and Anterior Eye)

Tear film interferometry assessment after intense pulsed light in dry eye disease: A randomized, single masked, sham-controlled study
Inadequate meibomian glands (MGs) secretion can lead to dry eye signs and symptoms. Tear film lipid layer (TFLL) secreted by MGs protects and prevents rapid evaporation of tear film. The purpose was to assess TFLL alteration and function in patients with evaporative dry eye (EDE) using tear interferometry after optimal pulse light technology (OPT) intense pulsed light (IPL).

The value of observational studies in eye care today
Health care professionals are taught that the “gold standard” evidence to guide clinical decisions is the randomized clinical trial (RCT). Although I take no issue with the statement, it ignores the foundational role of observational studies to provide background information to characterize diseases. This information is essential to design a robust RCT. RCTs can demonstrate many things: whether treatments work to manage or cure diseases, which type of patient is best suited for the treatment, what side effects can be expected, and the proper dosage of a drug or design of a device, to name a few.

Italian translation, validation, and repeatability of Standard Patient Evaluation of Eye Dryness (SPEED) Questionnaire
The assessment of symptoms of dry eye disease using a questionnaire is an effective and simple method of quantifying symptoms. The aim of this study was to translate the SPEED questionnaire and adapt it for the Italian language and verify the main psychometric performance of the translated version, including repeatability and agreement.

Stabilization of comfort and visual quality after the insertion of soft contact lenses
Assessing soft contact lenses properly and informing new users about different aspects such as alternative materials, designs, lens care systems, time of use, among others, during the contact lens fitting process is critical to prevent their dropout [1]. Considering that the contact lens fitting process depends on several factors such as contact lens movement, comfort, visual quality, or reflex tear secretion, only a few studies proposed when the best moment to evaluate soft contact lenses for the first time should be.

Pharmaceutical-loaded contact lenses as an ocular drug delivery system: A review of critical lens characterization methodologies with reference to ISO standards
Therapeutic contact lenses for ocular drug delivery have received considerable interest as they can potentially enhance ocular bioavailability, increase patient compliance, and reduce side effects. Along with the successful in vitro and in vivo studies on sustained drug delivery through contact lenses, lens critical properties such as water content, optical transparency and modulus have also been investigated. Aside from issues such as drug stability or burst release, the potential for the commercialization of pharmaceutical-loaded lenses can be limited by the alteration of lens physical and chemical properties upon the in...
