Purpose: to assess the position of the intraocular lens (IOL) in patients with secondary membranous cataract before and after Nd: YAG laser capsulotomy according to optical coherence tomography (ОСТ) of the anterior part of the eye. Material and Methods. The patients are divided into two groups. In the 1st group (n=105), the weakness of the lens ligaments was excluded; in the 2nd group (n=36) patients with concomitant ophthalmopathology were considered. All patients underwent standard ophthalmological examination, YAG laser discision of secondary cataract, and dynamic ОСТ of the anterior part of the eye. Results. After surgery, the visual acuity of patients in thelst group increased from 0.19±0.1 to 0.81±0.09 (p=0.01), in the 2nd group from 0.08±0.1 to 0.72±0.08 (p=0.02). There was no significant change in the position of the IOL after the operation in patients of thel st group. In some patients of the 2nd group, in the long-term period, an increase in the distance between the posterior surface of the cornea and the anterior surface of the IOL was revealed. In tow cases, the developed IOL dislocation required surgical intervention. Conclusion. Nd: YAG laser capsulotomy is a highly effective and low-trauma surgery for secondary cataract. In patients with Nd: YAG lens ligament weakness, laser capsulotomy may be a factor in the progression of IOL dislocation into the vitreous body. ОСТ allows you to assess the position of the IOL, the state of the ligamentous apparatus, the presence and progression of IOL dislocation.
