I-A yag laser capsulotomy posterior yinkqubo eyenziwa ukuphatha umbono ogqamile ongase uhlale ngemuva kokuhlinzwa kwe-cataract eye .
I-cataract iyi-clouding noma i-lens of human eye iso. I-cataract yiyona imbangela ehamba phambili yobumpumputhe phakathi kwabantu asebekhulile kunama-55. Iningi labantu asebekhulile banezinga elithile le-lens clouding, okuyingxenye evamile yokuguga.
Kodwa-ke, izifo zengozi zingenzeka kwezinye izizathu ngaphandle kokuguga. Ingane ingazalwa nge-cataract yokuzalwa. Futhi, ukuhlukunyezwa iso kungabangela i-cataract ephawulekayo. Ezinye imithi, njenge-prednisone, i-corticosteroid, ingabangela ukonakala. Okokugcina, ezinye izimo zezokwelapha ezifana nesifo sikashukela zingabeka engozini yokuthuthukisa i-cataracts ekuqaleni.
Uma uzibuza ukuthi kunjani ukuthi ube ne-cataract, cabanga ngokubheka ngefasitela ephazamisekile, efiphele. Ama-cataracts enza insimu yakho ebonakalayo ibonakale ingenangqondo noma ifinyelelekile.
Izimbangela
I-cataract ithinta i- lens iso.
I-lens itholakala ngemuva kwe-iris. Inesibopho sokugxila ekukhanyeni kwe-retina, nokukhiqiza izithombe ezicacile, ezibukhali. I-lens inamandla okuguqula isimo, eyaziwa ngokuthi indawo yokuhlala. Nokho, njengoba amehlo ekhula, i-lens iyanzima futhi ilahlekelwe ikhono layo lokubamba.
I-lens yonke iqukethe ngaphakathi kwe-capsule lens.
Ngezinye izikhathi ngemuva kokuhlinzwa kwe-cataract, ingemuva noma ingxenye engaphansi kwe-capsule lens , noma i-lens ehlanganisa, iguquguquka noma ivuliwe.
Lokhu kuphakama kuvame ukubangelwa amangqamuzana akhula ngemuva kwe-capsule, okwenza kube nombono ongenalutho, ukukhanya kwe-glare noma ukuzwela okukhanya. Nakuba kungenjalo i-cataract yangempela, ngokuvamile ibizwa ngokuthi "i-cataract yesibili." Le cataract yesibili ivame kakhulu ezigulini eziye zahlinzwa ukuhlinzwa kwe-cataract. I-cloudiness ingathuthuka ngokushesha emva kokuhlinzwa kwe-cataract noma eminyakeni eminingi ngemva kokuhlinzwa kwe-cataract.
Ukuze uphathe le-capsule yokugcizelela kokugcina, odokotela basebenzisa uhlobo lwe-laser olubizwa ngokuthi i-Yag laser ukwenza imbobo ngemuva kwe-capsule ukuze ususe i-cloudiness ukuze ukukhanya kudlule ngokukhululekile emuva kweso.
Inqubo
I-YAG laser capsulotomy posterior iyindlela yokwelashwa engadingi i-anesthesia. Inqubo ayibuhlungu futhi ithatha kuphela phakathi kwemizuzu emihlanu no-10. Ezinye iziguli zibona izindawo ezincane noma izintambo emva kwenqubo. Ngokuvamile, iziguli zibekwa phezu kwe-eye anti-inflammatory drop for a week. Ezimweni eziningi, i-YAG laser postsuit capsulotomy izobuyisela umbono emuva kokujwayelekile. Kodwa-ke, izikhathi eziningi umbono noma i-lens kadokotela obekugqoke ngaphambi kokuba ukwelashwa kwe-YAG kungasanelisi. Odokotela abaningi bazokwenza ukuvakashelwa kokulandelela cishe ngesonto noma amabili. Kulolu hambo, indawo ekhishwe kuyo izohlolwa. Udokotela uzophinde asebenze futhi angase abeke izibuko ezintsha.
Uma inqubo ye-laser ye-YAG isenziwa, ukungabi nosizi noma ukungafihli akukwazi ukubuyela. Ezimweni eziningi, uma kwenziwa inqubo yeLaser YAG, umbono ubambelele isikhathi esithile.
