“…Future studies on the relationship between capsular bend formation and posterior capsule–optic inadhesion using anterior segment OCT may be necessary to explain this phenomenon (Zhao et al. ). Another interesting outcome for the accumulated fluid is evident in patients with inadhesion implanted with an MC X11 ASP IOL.…”

ABSTRACT.Purpose: To investigate the prevalence and morphologic and clinical features of posterior capsule-optic inadhesion following cataract surgery. Methods: In this prospective cohort study, we examined 518 consecutive patients who had undergone uneventful phacoemulsification and posterior chamber intraocular lens (IOL) implantation. They were assigned into five groups based on the type of IOL used: MC X11 ASP, Rayner 920H A, ZCB00, SN60WF and KS-3Ai. Routine ophthalmic examinations were performed. Patients were followed up at 1 day, 1 week, and 1 and 2 months postsurgery. Anterior segment photography, Scheimpflug imaging and KR-1W aberrometry were conducted after the patients' pupils were dilated. Results: The overall rate of posterior capsule-optic inadhesion on the first day after surgery was 215/518 (41.5%), and it decreased to 37/518 (7.1%) at 2 months postsurgery. Posterior capsule-optic inadhesion can be morphologically classified into five types with three outcomes, of which gradual absorption of the accumulated fluid predominated for all IOLs. The clinical characteristics of patients with inadhesion varied with IOL type. Notably, visual quality data (Strehl ratios and modulation transfer function) were poorer in patients with posterior capsule-optic inadhesion, especially in those with irregular forms of suspension. Four cases of capsular contraction syndrome were identified among the patients with inadhesion. Conclusions: Posterior capsule-optic inadhesion is a prevalent capsule-IOL interaction following cataract surgery. Although the accumulated fluid is absorbed in the majority of patients, its adverse effects on visual outcomes, especially visual quality in the operated eye(s), must not be underestimated in patients with persistent inadhesion.

“…The most probable cause of the PCO was the preoperative high myopia exceeding Posterior capsular opacification in highly myopic eyes with an endocapsular equator ring -8.75 D. Because cataracts induce myopic changes, it seems more reasonable to study the axial length. Vass et al [7], Tehrani et al [8], and Zhao et al [9] report that in highly myopic eyes, the capsular bag enlarges along with elongation of the axial length. As shown in Table 1, the axial length of the capsulotomy eye was considerably long and ranged from 25.86 to 29.97 mm.…”

“…Прослежена положи-тельная динамика в течение 1-2 месяцев, в ряде случаев (7,1-26,8%) обнаружено отсутствие адгезии ЗКХ к ИОЛ в более поздние сроки, оценено влияние данного состоя-ния на качество зрения, определены периоды формиро-вания капсульного перегиба через край оптической части ИОЛ, которые в различных исследованиях варьировали от 10 дней до 1 месяца и более [6,7,9,10]. Сравнительные исследования выявили более слабую динамику трансфор-мации пространства капсульный мешок хрусталика-ИОЛ при высокой миопии, а также отличия в формировании взаимоотношений ЗКХ-ИОЛ при имплантации различ-ных моделей линз [6,[8][9][10][11]19]. Хирургия катаракты индуцирует трансформацию многих структур переднего отрезка глаза, так как суще-ственно уменьшается содержимое капсульного мешка хрусталика, что обусловливает его сокращение, сбли-жение переднего и заднего листков, а соответственно, и точек прикрепления волокон цинновой связки с упло-щением ее трехмерной структуры [13,20].…”

Purpose— to study the relations between the posterior capsule (PC) and intraocular lens (IOL) after cataract surgery in pseudoexfoliation syndrome (PEX).Patients and methods. We examined 46 eyes of 37 patients with PEX who underwent a standard and uncomplicated phacoemulsification. The age of patients was 60–94 years. Postoperative period ranged from 1 day to 10 years. An optical coherence tomography (OCT) (RTVue XR Avanti, “Optovue”) was used to image the IOL-PC space in early and late postoperative period.Results. In the first days full contact PC-IOL was not observed in any case. The maximum of space PC-IOL was noted on the first day postoperatively. Posterior capsule had a wavy or folded profile on the scans. In the next two weeks we observed a decrease of the distances between posterior capsule and IOL. After 1 month we noted the formation of capsular bend around optic edge, the full adhesion of posterior capsule to IOL was not detected. In the late postoperative period the fibroplastic and proliferative capsular changes with secondary discontact PC-IOL was noted. Primary inadhesion of a posterior capsule to IOL was recorded in half of the cases.и. High resolution OCT was suitable for quantitative analysis of IOL-PC space. Involution changes in structures of anterior segment in the eyes with PEX had a role in closure of the IOL-PC space. Complete adhesion of posterior capsule to IOL was not observed in the majority of eyes with PEX.
