“…Тахчиди способ импульс-ирригации, который основан на отделении сбалансированным солевым раствором ВЭ от подлежащих структур переднего отрезка глаза и последующей самопроизвольной эвакуации его через основной разрез [6]. Кроме того, для решения этой проблемы можно применить окрашенный ВЭ, что позволит контролировать его наличие в глазу [15,16].…”

“…В зависимости от характеристики ВЭ, используемого для заполнения передней камеры перед имплантацией ИОЛ, все глаза были случайным образом разделены на 2 группы. В 54 глазах первой (основной) группы применяли окрашенный ВЭ, который готовили по способу, предложенному F. Polit и A. Polit [15] для окрашивания передней капсулы. Для этого в шприц, содержащий 0,55 мл вискоэластичного раствора 1 % гиалуроната натрия, добавляли 0,1 мл красителя трипановый синий Rhex ID (Appasamy, Индия), а затем проводили смешивание двух субстанций посредством нескольких перемещений плунжера шприца назад и вперед.…”

BACKGROUND: The reasons for the development of postoperative reactive inflammation under optimal conditions for the operation are errors in the surgical technique and the presence of viscoelastic residues. The likelihood of developing ophthalmic hypertension exists with the use of viscoelastic of any type. Its incomplete evacuation can be explained by the difficult visualization due to its transparency. Analysis of the dependence of the postoperative period course on the quality of viscoelastic removal at phacoemulsification can be considered to be relevant and expedient. AIM: The aim was to study the type of the postoperative period course depending on the quality of viscoelastics removal at phacoemulsification. MATERIALS AND METHODS: 104 eyes of randomly chosen patients who underwent femto-laser assisted phacoemulsification, divided into 2 groups according to ophthalmic viscoelastics characteristics (colored or transparent). Both groups were split into 2 subgroups each depending on method of viscoelastics removal. Tonometry and biomicroscopy were performed 3 hours after phacoemulsification and on the post-op Day 1. Patients with Tyndall effect were examined daily until its disappearance. RESULTS: At comparable preoperative IOP indices, its elevation 3 hours after surgery took place in subgroups 2a and 2b, the highest being in subgroup 2a. The greatest number of eyes with Tyndall effect, at all follow-up periods, was found in subgroup 2a, the lowest in subgroup 1b. The total number of eyes with keratopathy (as epitheliopathy) observed 3 hours after surgery was 7, four of them being from subgroup 2a. CONCLUSIONS: The conducted research showed that the type of early postoperative period course of phacoemulsification depends on visualization possibility of the viscoelastic and of the method of its removal. Minimal changes of hydrodynamics and maximal number of eyes with absence of inflammation took place when using colored viscoelastic and impulse irrigation method.

BACKGROUND: Main methods of intraoperative secondary cataract prevention are measures aimed at the formation of full contact of the intraocular lens (IOL) with the posterior capsule. The diastasis between the IOL and the posterior capsule is explained by the presence of viscoelastic in the interface. Maximum visualization of the stained viscoelastic will obviously make it possible to completely remove it from the eye, which will increase the number of eyes with the optimal IOL posterior capsule interface with standard phacoemulsification. AIM: The aim was to study IOL posterior capsule interface status after phacoemulsification of senile cataract in relation to viscoelastic visualization. MATERIALS AND METHODS: 122 eyes of 122 patients were included, which underwent phacoemulsification of senile cataract with femto-laser assistance and were divided into 2 groups depending on viscoelastic characteristic (colored or transparent) used for anterior chamber filling prior to IOL implantation. IOL posterior capsule interface status was examined on the 1st and 7th day post-op in order to evaluate the contact between two structures. RESULTS: On the 1st day post-op, the absence of contact between IOL and posterior capsule was noticed more often in the second group, the number of eyes with this type of interface was 1.5 times lower in the 1st group. On the 7th day after surgery, optimal interface had place in 9 out of 10 eyes in the 1st group, in comparison with 2/3 of patients from the second group. CONCLUSION: Conducted investigation showed that the use of colored viscoelastic allowed creating the optimal IOL posterior capsule interface on the 7th day post-op in 87% of eyes of the main group in comparison with 67% eyes from the control group (the difference is statistically significant). The absence of contact between IOL and capsule can be considered as relative capsule block, which may form the high risk of secondary cataract.
