Abstract     Background. To report clinical features of late calcification of hydrophilic acrylic intraocular lenses (IOL)requiring explantation and to discuss the surgical management. Methods. 100 eyes of 94 patients presenting with Hydroview IOL opacification severe enough to require explantation were enrolled in the study. Lens excange procedures were performed in Novo mesto Hospital between February 2002 and September 2004. Medical and ophthalmic histories were obtained. Surgical details and visual acuity before and after IOL substitution were retrieved. Explanted lenses were sent for evaluation. Results. 99 calcified IOLswere exchanged with hydrophobic acrylic lenses. In 88 cases IOL was placed in the capsular bag and in 11 cases in the ciliary sulcus. One eye was left aphakic. The mean time between phacoemulsification and IOL explantation was 34.9 months. The mean improvement in visual acuity was 3.8 Snellen lines. The analysis of IOLs demonstrated that the opacification was due to surface calcification. Conclusions. Intraocular lens excange is effective in patients with loss of vision from calcified IOLs. After the procedure vision can be restored to the level before the formation of lens opacification. The majority of treated patients enjoy improvement in vision. However, the amount of visual recovery is limited by coexisting illness.
Summary     Izvleček. Opisujemo klinične značilnosti kalcifikacije hidrofilnih intraokularnih leč (IOL) ter predstavljamo operativno tehniko zamenjave. Metode. V raziskavo je bilo vključenih 94 bolnikov (100 oči), pri katerih je bila opravljena operacija zamenjave motne IOL Hydroview. Operacije so bile narejene v Splošni bolnišnici Novo mesto med februarjem 2002 in septembrom 2004. Povzeli smo spremljajoče očesne in sistemske bolezni, opisali smo operativno tehniko, zaplete ter spremembo v vidni ostrini. Odstranjene IOL smo poslali na analizo. Rezultati. Zamenjali smo 99 kalcificiranih leč s hidrofobnimi akrilnimi lečami. V 88 primerih smo IOL vstavili v kapsularno vrečko, v enajstih pa v sulkus. V enem primeru leče nismo vstavili. Povprečen čas med fakoemulzifikacijo in zamenjavo IOL je bilo 34,9 meseca. Vid se je v povprečju izboljšal za 3,8 Snellenovih vrstic. Analiza odstranjenih leč je pokazala kalcifikacijo kot vzrok za zamotnitev IOL. Zaključki. Operacija zamenjave motne intraokularne leče je uspešna in varna. Pri večini bolnikov se ostrina vida po posegu izboljša, stopnja izboljšanja pa je odvisna od morebitnih spremljajočih očesnih bolezni.
