The aim of the study was the assesment of effectivness of phacoemulsification procedure in patients with cataract and pseudoexfoliation syndrome. Analysed group consisted of 72 eyes (8 patients), age 53 - 93 years with PEX and 50 eyes (50 patients), age 49-82 without PEX. All cases have performed the phacoemulsification with implantation of artificial posterior chamber lens using small incision procedure. In more than 50% of patients marked postoperative improvement of visual acuity up to 0,6. Year after operation significant decrease of intrabulbar pressure was observed. We conclude that phacoemulsification in cataract treatment is an efficient and save procedure with improvement of patient's visual acuity and with low number of postoperative complications.
