RISK FACTORS FOR POTENTIAL CОMPLICATIONS OF CATARACT SURGERY İN THE EYES WITH VARYING DEGREES OF PSEUDOEXFOLIATIVE SYNDROME DEVELOPMENT

Abstract

Purpose – toinvestigate the predictors of potential complications of cataract surgery in eyes with varying degrees of pseudoexfoliation syndrome (PES) from the standpoint of choosing the optimal treatment tactics.

Material and methods
Results of a survey of 150 patients aged 56 to 86 years old (mean age 72.2 ± 0.9) before cataract surgery, of which 12 had open-angle glaucoma. Ophthalmic examination methods: visometry (without correction, with correction), 2-stage biomicroscopy (with a narrow pupil, after tonometry – with mydriasis), gonioscopy, ultrasonic biomicroscopy (UBM-plus, Accutome, USA).

Results
From the point of view of cataract surgery, the most significant predictors of potential complications of cataract surgery (weakening of the pupil reaction, changes in the Zinn ligament fibers) are determined by the degree of PES development, 3 degrees (stages) of PES development, characteristic changes are distinguished. In assessing the degree of development of PES, it is important to highlight two main points: the nature of the deposits of pseudoexfoliative material (PEM) and the severity of dystrophic changes in structures (dystrophic component).

Conclusion
The choice of the optimal tactics of surgical treatment of cataracts in eyes with PES is based on the degree of progression of the syndrome, including PEM deposits, a dystrophic component of changes in the structures of the eye.
