Abstract:
Most users of soft contact lenses sooner or later face the problem of dry eyes when wearing them. Despite the development of polymer chemistry for contact lenses, which include additional moisturizing components, this problem is still relevant today. The use of tear substitutes and moisturizers is effective at the initial stage of treatment. In this regard, the appointment of orthokeratological lenses to users with soft contact lenses may be one of the possible solutions, including in patients of presbyopic age.

Abstract:
Orthokeratology is a method of non-surgical correction of refraction, which is based on the principle of biomechanical changes in the curvature of the cornea under the influence of «reverse geometry». This method was developed more than 50 years ago, however, it became widely used only in the early 2000s. The basis of this method is the use of special orthokeratology lenses that patients wear during the night. Peculiarity of these lenses is the ability to change curvature of the cornea, resulting in a flattening of its central part and thickening of the paracentral and peripheral sections, whi

Accommodation disorders in young people are more common than diagnosed. This review is based on the data of domestic and foreign literature and studies the effect of contact lenses of various designs on accommodation. Particular attention has been given to bifocal soft contact lenses as one of the recognized interventions for treating juvenile progressive myopia and their ability to slow axial elongation. Key words: accommodation, myopia control, bifocal contact lenses, orthokeratology.

Orthokeratology is a method of correction of ametropia, which has been widely used throughout the world. In the presented review, based on the data of domestic and foreign literature, possible undesirable phenomena that occur when using orthokeratological lenses are described. Scien¬tists come to the conclusion that, despite the possibility of complications, the risk of undesired symptoms is significant¬ly reduced when the rules of the use and care of orthokera¬tology lenses are strictly followed, and that their incidence is less frequent than when using soft contact lenses.

The orthokeratology (OK) lens, a specially designed contact lens, has been used worldwide as an effective method of myopia control. However, the OK lens is associated with an increased risk of Acanthamoeba infection. Many primary practitioners are concerned about this infection because of its relative rarity, the lack of promising therapeutic medications, and the need for referral.

Abstract:
Main aim of this article was a systematic review on causes and management of Myopia progression in children. Myopia is a general disorder, affecting just about one-third of the US popula­tion and over 90% of the population in some East Asian countries. Elevated amounts of myopia are connected with a bigger risk of sight-threatening troubles, such as retinal detachment, choroidal degeneration, cataracts and glaucoma. Slowing the progression of myopia could potentially advantage millions of children in the India. Few approaches used for myopia organize have proven to be useful. Treatment options

Abstract:
Purpose: Literature is relatively silent on safety profile and predictability of orthokeratology lenses in terms of myopia correction and prevention of further progression, especially in semi-tropical countries; this study was designed to fill this gap.
 Methods: This prospective, intervention case series enrolled 30 eyes of 30 patients with myopia up to –5.5 diopters (D). Patients were randomized into two groups of 15 each; the study group was prescribed overnight orthokeratology (OK) lenses, while the control group used daily wear conventional soft contact lenses.

Abstract:
Purpose: The purpose of this study was to conduct a meta-analysis comparing rigid gas permeable lenses (RGP) with soft contact lenses (SCL), spectacles and orthokeratology (OK) lenses for myopia control with respect to axial length elongation, spherical equivalent and measures of corneal curvature. Methods: Medline, Cochrane, EMBASE, and Google Scholar databases were searched to September 29, 2015 using the following keywords: rigid gas permeable contact lens; refractive error; and refractive abnormalities. Randomized controlled trials, two-arm prospective studies and retrospective studies of

Abstract:
In this paper, we report the relation between fabric characteristics and animal model cornea modifications associated with extended use of fluoro-siloxanyl styrene rigid gas permeable contact lens. Siloxanyl styrene and fluoromethacrylate rigid gas permeable contact lens is a newly designed optical medical device used in orthokeratology with an FDA approval of continuous wear for up to 30 days. To assess the influence on the cornea an animal model was used and histological data were collected. Scanning electron microscopy (SEM) was performed on the used lenses. Our conclusions concedes that wi

Abstract:
PurposeTo determine if the spatial distribution of the relative corneal refractive power shift (RCRPS) explains the retardation of axial length (AL) elongation after treatment by either orthokeratology (OK) or multifocal soft contact lenses (MFCLs).MethodsChildren (8–14 years) were enrolled in the OK (n = 35) or MFCL (n = 36) groups. RCRPS maps were derived by computing the difference between baseline and 12-month corneal topography maps and then subtracting the apex values. Values at the same radius were averaged to obtain the RCRPS profile, from which four parameters were extracted: (1) Half
