Spring Session Athens - 7 June

Over the last decade, Ortho-k lenses have significantly progressed in design based on better knowledge of the cornea shape. One of these new developments is the ability to better design empirical Ortho-k contact lenses, reducing the chair time and the number of refits. Previous studies showed that many remakes were often necessary. Nowadays we have sophisticated CNC lathing technology machines + reverse curves + topography and softwares . The construction of Ortho-K designs continues to morph as innovators with four to five curves (or zones) attempted to improve fitting characteristics. Ortho-K has increased in popularity for pediatric myopia. More practitioners prescribe overnight Ortho-K as treatment to reduce myopia progression and axial elongation in children instead of standard single- vision correction.

Empirical Ortho-k contact lens fitting based on corneal topography data seems to have several advantages. Reduced chair time and less fatigue of practitioner and patient are two of them. The patients are very satisfy with the speed and the efficiency of the fits and the results. The Orthokeratology lens market is expected to grow in the coming years.

Dr Zoi Kapoula, Research Director at the CNRS, Paris. Dr Kapoula’s presentation will assess ocular movements and dyslexia, in particular, difficulties learning and links between binocular visio-motor problems. How AI can help to predict, anticipate and personalise the management of binocular vision problems in children to aid reading ability. Optimising the optical correction: the importance of a precise prescription and its impact on reading fluency. An introduction to precision oculometry – how to measure the efficiency of different prescription lenses for reading.

A description of the Glasses in Classes (GiC) project whose aim was to try to ensure that children who fail school vision screening are taken for follow-up eye examination and that those children who need glasses actually end up wearing them whilst at school.
