“…Over the years, different methods have been proposed to make cataract surgery easier and safer, but the revolutionary breakthrough in this area occurred with the development of phacoemulsification. With the use of this technique, it has been possible to achieve a good standard of low-risk efficacy compared to the techniques previously used [9]. The advent of Femto Laser-Assisted Cataract Surgery (FLACS) has indeed decreased the use of ultrasonic energy in the anterior chamber.…”

The aim of this study is to evaluate the difference in the number of endothelial cells after cataract operations with phacoemulsification by using a balanced salt solution (BSS) at standard temperature (about 20 °C) and at 2.7 °C. Two groups, comprising 214 individuals in total, participated in this study; patients were operated on using BSS bottle at about 20 °C and 2.7 °C in the first and second groups, respectively. All operations were conducted by the same surgeon and in similar conditions. One month after the operations, endothelial cells in the two groups were checked. For patients in Group 2, an important reduction in the loss of endothelial cells was observed.

“…Для защиты эндотелиальных клеток, особенно при низком их количестве, стандартом на сегодняшний день является использование вискохирургической техники «мягкой оболочки» (soft-shell technique) по S. Arshinoff [13]. Еще одним способом защитить эндотелий при проведении факоэмульсификации катаракты является предложенный S. Li et al (2017) так называемый «слоеный пирог» [14].…”

Хирургия катаракты является одним из самых динамично развивающихся направлений в офтальмологии. Стандартом современной хирургии катаракты на сегодняшний день остается метод ультразвуковой факоэмульсификации (ФЭК). Достаточно часто оперативное вмешательство может быть осложнено рядом неблагоприятных факторов: слабостью цинновых связок, высокой плотностью ядра, недостаточностью эндотелиального слоя клеток роговицы, узким ригидным зрачком, аниридией. Современная оптимизация всевозможных процессов привела к тому, что при проведении ФЭК активно используется фемтосекундный лазер. Наряду с успешным выполнением собственно ФЭК важнейшим аспектом работы катарактального хирурга является правильный выбор интраокулярной линзы (ИОЛ). Разработка асферичных ИОЛ позволила существенно улучшить функциональные результаты вмешательства, обеспечивая пациентам более высокие зрительные функции, в первую очередь в мезопических и никтопических условиях. В XXI в. появились новые возможности для пациентов, в частности полный отказ от очковой коррекции в послеоперационном периоде после хирургии катаракты с имплантацией мультифокальных ИОЛ. Одной из последних разработок является линза, позволяющая получить большую глубину фокуса с усилением псевдоаккомодации и использованием динамики зрачка. Внедрение таких линз может потребовать изменения представления о параметрах оптической системы глаза, что приведет к созданию новых формул расчета или модификации имеющихся и, возможно, обязательному учету хирургического вклада в рефракционный исход, а следовательно, откроет новый этап в развитии хирургии катаракты.

“…[16][17][18] Adverse effects at cellular and subcellular level that can contribute to ocular inflammation during cataract surgery are attributed to mechanical, thermal, and chemical mechanisms. Surgical instruments contact and turbulent fluids which are generated by the phaco tip's jackhammer effect are the causes of mechanical injury, 19,20 while high frequency ultrasound vibration at the tip or occlusion of the tip caused by the lens fragmentation during the emulsification are the causes of the thermal injury. 20,21 The imploding of cavitation bubbles that are generated during the procedure causes a chemical damage that is mediated by free radicals, formed in the aqueous humor.…”

Purpose: The aim of this study was to assess whether the intraoperative use of the cold eye irrigation balanced salt solution (BSS) could have a protective effect in preventing the anterior chamber flare and conjunctival hyperemia and, thus, in reducing patients discomfort after phacoemulsification. Materials and methods: About 214 patients were enrolled and randomly divided into: patients whose eye were irrigated with BSS at ~ 20°C (Group 1) and patients whose eye were irrigated with BSS at 2.7°C (Group 2). Anterior chamber flare, visual analogue score and conjunctival hyperemia were evaluated at 1, 3, 5, and 30 days after surgery. Results: In patients of Group 2 the anterior chamber flare, the visual analogue score and the conjunctival hyperemia, used as parameters to evaluated clinical inflammation, at 1 day after surgery were significantly lower than those in Group 1 who received BSS solution at operating room temperature ( p < 0.001), while at day 3, 5, and 30 there were not any significant differences. Conclusion: Our study provided evidence supporting the efficacy of the treatment with cold irrigation solution on reduction of anterior chamber flare, pain and conjunctival hyperemia already at 1 day after phacoemulsification, suggesting that cooling procedure was fully effective at controlling early post-operative inflammation.

Isolated Capsulorhexis Flap Technique in Femtosecond Laser-Assisted Cataract Surgery to Protect the Corneal Endothelial Cells

Abstract: Isolated capsulorhexis flap technique initiate a new approach to protect the endothelial cell. It is a simple technique with a short learning curve, but still need a further investigation to prove the protection of corneal endothelial cells.
