Irregular corneal shapes have always posed particular challenges for contact lens fitters. Keratoconus, pellucid marginal corneal degeneration, postoperative scarring and corneal steps following penetrating keratoplasty or refractive surgery, as well as scarring following trauma, can significantly impair the optical quality of the corneal surface.
A guide through awareness, science and practice Short-sightedness, medically known as myopia, has gradually and continuously crept into our school classrooms, families and optometry practices over the past decades. It is not a ‘trend’ but a global challenge that has a concrete impact on everyday working life. A fundamental question for optometrists and ophthalmologists is:…
Holy grail aberrations What I like about the contact lens field – as opposed to general medicine, for instance – is that we can ‘create things.’ Beautiful things. General medicine and eye care is more about dealing with existing conditions, while in the contact lens field, we can create vision. How cool is that? We…
The care and treatment of vision problems in childhood is particularly challenging, especially when conventional visual aids are not sufficient. A 21-year retrospective study by Carrasquillo et al. highlights the long-term effects and benefits of scleral lenses in pediatric care.
Everyone has an opinion on presbyopia. But let’s stick to the facts and answer this question: What is presbyopia, exactly, and what can we do about it? Part I here in GlobalCONTACT covered the mechanism of accommodation and presbyopia as well as definitions of the condition.
BostonSight, a nonprofit eye healthcare organization that advances the treatment of diseased and damaged corneas and dry eyes held their annual FitAcademy Retreat for Cornea and Contact Lens Residents and Fellows at New England College of Optometry (NECO) in Boston, September 13-14, 2024. This year marked the sixth iteration of FitAcademy, an educational retreat for…
Efficient contact lens care for soft contact lenses is particularly important for long-term and safe contact lens wear. At the last Opti Munich 2024, a start-up presented a completely new system that not only simplifies contact lens care, but also manages the amount of care product used sustainably.
The importance of contact lens characterization Why do wearers consider “soft” contact lenses (CLs) more comfortable than the “rigid” gas permeable (RGP) alternative? Thus, what does “comfort” mean from a scientific point of view? In this short article, we aim to emphasize the significance of meticulously characterizing and monitoring the physical parameters of CL materials…
Understanding Soft Lens Design & Fitting Celebrating 50 years of EFCLIN, urges us to look back – but also gives us a good opportunity to look forward. Artificial intelligence (AI) is getting a lot of attention lately, almost to the point of becoming a fashion statement: everybody is into artificial intelligence, it seems. Several recent…
“Which is better, one or two?” asks the doctor, to which the patient responds with “Neither.” This encounter may sound familiar to many eye care practitioners, particularly when refracting patients with irregular corneas.
