Ingabe amalensi angagqokwa nge-cataract?
Igama elithi "cataract" libhekisela esimweni se-pathological lapho i-lens, esimweni esivamile kufanele ibonakale ngokuphelele, iqala ukuguquguquka. Kungase kuguquguquke kancane noma ngokuphelele. Kuya ngezinga lokukhubazeka kokubona. Iso liyafana ngesakhiwo nekhamera. Ngaphansi kwe-cornea kune-lens yemvelo - i-lens, esobala ngokuphelele futhi eguquguqukayo, ingashintsha ukugoba kwayo ukuze igxilise ngokucacile isithombe ebusweni be-retina. Uma i-lens, ngenxa yezizathu ezihlukahlukene, ilahlekelwa ukukhanya kwayo, iba namafu, lokhu kuthinta kakhulu ukusebenza kwayo.
Ngokumelene nesizinda se-cataract, ukusetshenziswa kwama-lens kungenzeka ezimweni ezimbili - lapho kukhona izinkinga ezengeziwe ngombono noma ngemuva kokuhlinzwa okwenziwe kwi-lens.
Ama-contact lens ngokumelene nesizinda se-cataracts anganconywa kubantu abahlushwa yi-myopia, hyperopia, astigmatism. Kodwa uma usebenzisa ama-lens, kunezinkinga ezithile - ngenxa yazo, ukufinyelela kwe-oksijini ezindaweni zamehlo kuncishisiwe, okuthi, ngokumelene nesizinda se-cataract, kungaba yinto engathandeki. Kodwa-ke, ezinye izinhlobo zama-lens zivikelekile emisebeni ye-ultraviolet, engathinta kabi inkambo ye-cataract, isheshise ukuvuthwa kwayo. Ngakho-ke, indlela yokugqoka ama-lens kule pathology ingumuntu ngamunye.
Esikhathini se-postoperative, inkomba yokugqoka ama-lens oxhumana naye kuyoba ukungabi khona kwe-lens esweni. Ekuhlinzweni kwe-cataract, udokotela ususa ngokuphelele i-lens, ngaphandle uma ithathelwa indawo yokwenziwa, iso alikwazi ukugxila esithombeni ku-retina. Izibuko, amalensi e-intraocular (afakekayo) noma amalensi okuxhumana angasetshenziswa ukulungisa le nkinga. Bakhethwa ngabanye futhi kuphela nodokotela.
Imaphi ama-lens angcono kakhulu ku-cataract?

Izinhlobo zamalensi aqinile ngezinye izikhathi zinconywa kubantu abaye bahlinzwa ngaphansi kwe-anesthesia yendawo. Ngama-lens athambile, ayikho inkinga enjalo; kulula ukuwagqoka ekuseni ngemva kokuvuka.
Ekuqaleni, udinga ukugqoka amalensi ingxenye yosuku. Uma ukusebenza kwakungamazwe amabili, khona-ke kungenzeka ukufaka ama-lens amabili ahlukene - eyodwa yombono ocacile wezinto ezikude, okwesibili - okungenzeka kube nombono oseduze. Inqubo efanayo ibizwa ngokuthi "i-monovision", kodwa amalensi angakhethwa kuphela ukuze abone kude noma eduze, futhi izibuko nazo zinconywa ukulungisa izinkinga ezisele.

Ngesikhathi sokukhishwa kokuhlinzwa kwe-cataract, sikhuluma ngamalensi e-intraocular abekwe endaweni ye-lens yakho, eyekile ukwenza imisebenzi yayo. Lawa ma-lens, ngokungafani namalensi okuxhumana, afakwe esikhundleni se-lens esusiwe futhi ahlale lapho kuze kube phakade. Akudingeki ukuthi zikhishwe futhi zibuyiselwe ngaphakathi, zishintsha ngokuphelele ilensi. Kodwa ukuhlinzwa okunjalo kungase kungaboniswa kuzo zonke iziguli.
Ukubuyekezwa kodokotela mayelana namalensi we-cataract
"Yiqiniso, uma sikhuluma ngokusetshenziswa kwama-lens for cataracts, sikhetha amalensi e-intraocular, asivumela ukuthi sibuyisele imisebenzi ebonakalayo esigulini," kusho. udokotela wamehlo u-Olga Gladkova. - Njengamanje, kunemisebenzi yokushintsha ilensi ekhanyayo nge-intraocular lens ukuze kulungiswe ukukhubazeka kokubuka kwebanga eliphezulu lapho ukuhlinzwa kwe-keratorefractive kunganiki umphumela omuhle.
