Abstract
Description
Изобретение относится к области медицины, в частности к офтальмологии, и касается коррекции пресбиопии.The invention relates to medicine, in particular to ophthalmology, and for the correction of presbyopia.
Возрастное ослабление аккомодации диктует необходимость обязательного ношения очков для зрения на близком расстоянии. При наличии аномалий рефракции пациент должен иметь две пары очков - для дали и для близи, либо бифокальные или прогрессивные очки. Отрицательной чертой бифокальных очков является наличие резких перепадов из-за границы между линзами для дали и для близи, что многими пациентами плохо переносится, кроме того, у этих очков нет фокуса на промежуточные расстояния. Последний недостаток нивелируется прогрессивными очковыми линзами, но многими пациентами они не переносятся, необходим длительный период адаптации к ним. Кроме того, невелик срок их службы при достаточно высокой стоимости.Age-related weakening of accommodation dictates the need for mandatory wearing of glasses for vision at close range. In the presence of refractive errors, the patient must have two pairs of glasses - for distance and near, or bifocal or progressive glasses. A negative feature of bifocal glasses is the presence of sharp changes from beyond the border between the lenses for distance and near, which many patients are poorly tolerated, in addition, these glasses do not have focus at intermediate distances. The last drawback is leveled by progressive spectacle lenses, but they are not tolerated by many patients, a long period of adaptation to them is necessary. In addition, their service life is short at a rather high cost.
Офтальмологи ищут способ избавить людей от необходимости ношения очков. Известна коррекция пресбиопии контактными линзами, но они многими пациентами не переносятся, у части больных вызывают синдром «сухого глаза». Они сложны и дороги в использовании, так как для этого постоянно требуются расходные материалы для ухода за ними (1).Ophthalmologists are looking for a way to save people from the need to wear glasses. Correction of presbyopia with contact lenses is known, but they are not tolerated by many patients; in some patients they cause dry eye syndrome. They are complex and expensive to use, since this constantly requires supplies to care for them (1).
Известен способ коррекции пресбиопии путем удаления хрусталика и имплантации мультифокальной интраокулярной линзы (2, 5). Данный способ взят за прототип.A known method for correcting presbyopia by removing the lens and implanting a multifocal intraocular lens (2, 5). This method is taken as a prototype.
Недостатками данного способа является то, что далеко не всегда качество зрения вдаль и вблизи с такими интраокулярными линзами удовлетворяет пациентов (3, 4, 6).The disadvantages of this method is that far from always the quality of vision in the distance and near with such intraocular lenses satisfies patients (3, 4, 6).
Целью изобретения является создание способа коррекции пресбиопии. Эта цель достигается тем, что интраокулярная линза имеет торическую форму. Предлагаемый способ отличается от известных тем, что после удаления хрусталика торическую интраокулярную линзу располагают в глазу таким образом, чтобы создать прямой миопический астигматизм, таким образом оптическую силу глаза изменяют на миопическую только в вертикальном меридиане, благодаря чему пациент видит вблизи. При этом горизонтальный меридиан остается эмметропическим, позволяя видеть вдаль.The aim of the invention is to provide a method for correcting presbyopia. This goal is achieved by the fact that the intraocular lens has a toric shape. The proposed method differs from the known ones in that after removal of the crystalline lens, a toric intraocular lens is positioned in the eye in such a way as to create direct myopic astigmatism, thus the optical power of the eye is changed to myopic power only in the vertical meridian, due to which the patient sees closely. In this case, the horizontal meridian remains emmetropic, allowing you to see into the distance.
Сравнение предлагаемого способа с другими, известными в области офтальмологии, показало его соответствие критериям изобретения.Comparison of the proposed method with others known in the field of ophthalmology, showed its compliance with the criteria of the invention.
Способ реализуется следующим образом. Через тоннельный роговичный разрез производят факоэмульсификацию катаракты и имплантируют торическую интраокулярную линзу, расчеты которой позволяют получить прямой миопический астигматизм слабой степени, который обеспечивает пациенту возможность видеть вдаль и вблизи без дополнительной очковой коррекции.The method is implemented as follows. Through a tunnel corneal incision, cataract phacoemulsification is performed and a toric intraocular lens is implanted, the calculations of which make it possible to obtain direct myopic astigmatism of a weak degree, which allows the patient to see far and near without additional spectacle correction.
Способ может быть использован в работе стационарных офтальмологических учреждений.The method can be used in the work of stationary ophthalmological institutions.
