Abstract:
Introduction: According to a study done by the European Society of Ophthalmology
in collaboration with the International Myopia Institute in 2020 almost 400 million
Europeans suffered from Myopia, but it is estimated that their number will exceed
500 million by 2030. More treatments are available or medical devices, aimed at
preventing or slowing the progression of Myopia. Among them are
orthokeratological or nocturnal contact lenses, which remodel the cornea, changing,
as a consequence, retinal defocus into hypermetropia. But in the case of neglecting
the general anamnesis and the visual system, anatomical and functional
particularities of the patient, we risk expecting the lack of effectiveness of the given
method, the occurrence of unwanted side effects or complications.
Purpose of the study: Presentation of the particularities of the individual selection
of orthokeratological lenses.
Methods and materials: Case series presentation of patients with rare corneal
anatomical particularities.
Results and Conclusions: Correct individual selection of lenses for each patient is
important for obtaining the expected result. Only a correctly performed
keratotopography can give us ample information about the curvature, shape and
diameter of the cornea, the type of corneal astigmatism.
