Contact lenses vision correction is a method of correcting optical ametropias, including myopia. Currently, contact lenses for myopia control are gaining more and more importance.
The feasibility of using contact lenses is noted in the Federal Clinical Guidelines “Diagnosis and treatment of myopia in children” in case there is a need for continuous vision correction (when myopia of is higher than 1 diopter).
The advantages of contact lenses over glasses are: creation of a clearer image on the retina, reduction of aberrations, absence of a prismatic effect and the absence of a limitation of the field of view.
The main tasks of the department of contact lenses vision correction and orthokeratology are: organization of fundamental research, applied research and development in the field of correction and control of myopia, as well as the development of safety protocols and the effectiveness of the use of contact lenses in children and adults, the improvement methods of myopia control using contact lenses, including the development of new designs of orthokeratology lenses, lenses testing and introduction of new developments into clinical practice.
Particular attention is paid to the study of the anatomical and physiological characteristics of the eye when wearing contact lenses, to adaptation of the cornea to soft and rigid contact lenses, the scientific substantiation of indications, contraindications and selection of the optimal method for correcting ametropia in accordance with age and the presence of concomitant pathology individually for each patient.
The main goals of contact lenses vision correction:
Orthokeratology, as one of the methods of vision correction, is the driver of its development. According to researchers around the world, orthokeratology lenses are effective for inhibition myopia progression. One of the advantages of this method is the achievement of a refractive effect during sleep and freedom from correction during the daytime. In case of use of orthokeratology lenses in children, this allows full parental control, which increases the safety especially in children of primary school age
Despite the continuous improvement of materials and designs of contact lenses, some problems persist, such as discomfort when wearing, dry eyes, and the possibility of complications.
Comfort of wearing is also an important factor for patients themselves. New polymers are constantly being developed with the aim of imparting biomimetic properties to lenses, and lens designs as well as their manufacturing technologies are also being improved.
Many scientific studies are conducted all around the world to investigate the safety and effectiveness of using contact lenses, and there is a need to systematize scientific knowledge and develop clinical recommendations for practicing physicians.
