Abstract

Cataracts are defined as clouding of the crystalline lens which affects normal vision and are one of the most common causes of blindness worldwide, especially in developing countries. Even though incidence of cataracts increases in older age groups, multiple other factors can lead to premature lens opacifications, including genetic disorders, prenatal infections and trauma. Cataract formation is associated with deleterious effects on vision, such as myopic shift, monocular diplopia, reduction of contrast sensitivity and appearance of glare. Cataracts can be easily visualized using slit lamp examination. Indications for cataract extraction surgery include improvement of visual acuity and prevention of secondary complications, such as uveitis and glaucoma. Modern-day cataract extraction techniques can be divided into intracapsular and extracapsular. In general, cataract extraction surgery is very successful, with good patient outcomes and relatively low incidence of serious complications. Complications of cataract surgery can roughly be divided into preoperative, intraoperative and postoperative complications. Postoperative complications can further be classified as early (presenting <6 weeks after surgery) or late (presenting >6 weeks after surgery). Most of these complications can be adequately managed, with good expected outcomes.

Abstract (croatian)

Katarakte se definiraju kao zamućenja kristalne leće koja utječu na normalan vid te su jedan od vodećih uzroka sljepoće diljem svijeta, posebice u zemljama u razvoju. Iako učestalost katarakte raste u starijim dobnim skupinama, postoje čimbenici koji mogu dovesti do prijevremenog zamućenja leće, poput genetskih poremećaja, prenatalnih infekcija i trauma. Razvoj katarakte povezan je sa štetnim učincima na vid, kao što su pomak prema kratkovidnosti, monokularna diplopija, smanjenje kontrastne osjetljivosti i pojava blještavila. Katarakte se lako uočavaju pregledom mikroskopom s prorezom. Indikacije za operaciju ekstrakcije katarakte uključuju poboljšanje vidne oštrine i prevenciju sekundarnih komplikacija, poput uveitisa i glaukoma. Suvremene tehnike ekstrakcije katarakte mogu se podijeliti na intrakapsularne i ekstrakapsularne. Općenito, operacija ekstrakcije katarakte vrlo je uspješna, s dobrim ishodima za pacijente i relativno niskom učestalosti ozbiljnih komplikacija. Komplikacije operacije katarakte mogu se ugrubo podijeliti na preoperativne, intraoperativne i postoperativne komplikacije. Postoperativne komplikacije se dodatno mogu podijeliti na rane (javljaju se <6 tjedana nakon operacije) i kasne (javljaju se >6 tjedana nakon operacije). Većina ovih komplikacija može se adekvatno liječiti, s dobrim očekivanim ishodima.
