| Popis: | The aim is to present the phacoemulsification phaco-chop technique in a patient with pseudoexfoliation (PEX) syndrome without the use of additional pupil dilatation methods. Phacoemulsification surgery and posterior chamber intraocular lens implantation in patients with PEX syndrome is associated with a higher rate of intraoperative complications such as zonular dehiscence, capsular rupture, vitreous loss and dropped nucleus. Many options are available for pupils that cannot be dilated sufficiently with pharmacologic agents, such as viscodilatation (Healon 5), bimanual stretching, iris retractor-hooks, and many others. We present cataract surgery in a patient with sufficient mydriasis despite PEX syndrome. The operation was done successfully without intraoperative and postoperative complications. It is concluded that cataract surgery in patients with PEX syndrome is more complicated because of zonular weakness and poor pupillary dilatation. Therefore, these patients should be managed with utmost care and operated on in time by an experienced surgeon. Cilj je prikazati tehniku fakoemulzifikacije phaco-chop kod bolesnika sa sindromom pseudoeksfolijacije (PEX) bez primjene dodatnih metoda širenja zjenice. Fakoemulzifikacija i implantacija intraokularne leće u stražnju sobicu kod bolesnika sa sindromom PEX je povezana s povećanom učestalošću intraoperacijskih komplikacija, kao što su dehiscencija zonula, ruptura kapsule, gubitak staklovine te utonuće nukleusa leće. Za zjenice koje ne pokazuju zadovoljavajuće širenje uz primjenu farmakoloških sredstava postoje brojne druge metode kao što su viskodilatacija (Healon 5), bimanualno "istezanje", "retraktor kukice za šarenicu" te mnoge druge. Opisuje se ovaj zahvat kod bolesnika sa zadovoljavajućom midrijazom usprkos sindromu PEX. Operacija je napravljena uspješno bez intraoperacijskih i poslijeoperacijskih komplikacija. Zaključak je kako je kirurgija katarakte kod bolesnika sa sindromom PEX složenija zbog slabosti zonula i slabo proširene zjenice, zbog čega ovi bolesnici zahtijevaju osobitu pozornost i iskustvo kirurga. |
