Abstract
Objective: The evaluation of the frequency and level of the severity of post operational dislocation of the intraocular lens (IOL) among patients having complicated cataract.
Methods: Retrospective analysis of the reasons of IOL postoperative dislocation was conducted. 11251 phacoemulsifications (PE) dealing with complicated cataract were conducted in Khabarovsk branch of ISTC “Eye microsurgery” for the period from 2010 to 2020. Post operational dislocation of the lenses of non-traumatic genesis was registered in 33 cases – 0.29%.
Results: There were 19 men and 14 women aged from 50 to 89 years old among people having post operational dislocation. The period of patients appeals widely varies – from 4 months to 10 years, 4.7 years on average. Over time after PE, the frequency of such appeals increased progressively. IOL dislocations as a rule are based on a varying degree of the weakness of ligamentous apparatus of the lens as a consequence of accompanying ophtalmopathology that wasn’t detected before operation.
Conclusions: Patients having preoperative weakness of the zonular lens support are advised to have post operational dynamical monitoring of the IOL anatomical position for the period not less then 5 years.
