В настоящее время все более популярным становится подбор так называемых мини-склеральных линз от 15,0 до 17,0 мм в диаметре. Существующие номенклатуры отталкиваются только от величины ГВДР и общего диаметра линзы. Поэтому важно более глубокое понимание отличий меньших мини-склеральных линзы от больших.</p></abstract><trans-abstract xml:lang="en"><p>A scleral contact lens (SCL) can be defined as a lens that only rests on the sclera. Raised from the cornea and limbus, the total diameter must be greater than the horizontal visible iris diameter (HVID) and the extension of the limbus. Currently, the most commonly used lenses are scleral lenses with a diameter between 15.0 and 17.0 mm, the so-called mini-scleral lenses. The existing nomenclature of scleral lenses is based only on HVID and total diameter. It is therefore important to further differentiate smaller minisclera lenses from lager ones.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>контактные линзы</kwd><kwd>лимб</kwd><kwd>склеральные газопроницаемые контактные линзы</kwd><kwd>общий диаметр</kwd><kwd>зона посадки</kwd><kwd>роговица</kwd></kwd-group><kwd-group xml:lang="en"><kwd>scleral contact lens (SCL)</kwd><kwd>horizontal visible iris diameter (HVID)</kwd><kwd>total diameter (TD)</kwd><kwd>landing zone (LZ)</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Lupelli L.
