Kuyini ukuhlolwa kwe-PAM?
Ama-cataracts abangela ukulahlekelwa kombono kubantu abaningi. Ezimweni eziphambili ze-cataract, ukukhishwa kokuhlinzwa kwe-lens eguquguqukayo kuyindlela yokwelashwa engcono kakhulu. Ngaphambi kokuba uzinikele ekuhlinzekeni kwe-cataract , noma kunjalo, kungcono ukwazi ukuthi ubuningi bokulahlekelwa kombono wakho kungabanikela ekubhekaneni ne-cataract.
Uma iso lakho liphilile ngenye indlela, ubuciko bakho obubonakalayo kufanele buthuthuke kumazinga avamile uma i-cataract isusiwe.
Kodwa-ke, ezinye iziguli ezinesifo sengculazi zingase zibe nezinye izifo zeso ezingenza kube nzima ukunquma ukuthi ukususa i-cataract kuzothuthukisa umbono.
Izinga elilinganiselwe lombono elitholiwe lingalinganiselwa ngokusebenzisa ukuhlolwa kwe-PAM, noma ukuhlolwa kwamamitha okungaba yi-acuity. Ukuhlolwa kwe-PAM akuyona inkimbinkimbi kakhulu kunokufunda ishadi lesiso elijwayelekile. Yini eyenza ukuhlolwa kwe-PAM okuyingqayizivele yukuthi esikhundleni sokubuka ngaphandle kweshadi lesiso eludongeni, ishadi lamehlo lihlolwe ngqo emehlweni akho bese ungena ku-retina yakho ngokukhanya okuthile okufana ne-laser, okuzama ukweqa i-cataract ngokwayo. Ngoba ukuhlolwa kudlula i-cataract, umbono olinganiselwe ukulinganisa ukuthi umbono wakho ungathuthuka kangakanani ngemuva kokuhlinzwa kwe-cataract.
Ukuhlolwa kwe-PAM kuyasiza kakhulu ezigulini ezinezinye izifo zamehlo njenge- macular degeneration . Nakuba ukuhlinzwa kwe-cataract kuphephile, kukhona izinhlekelele zokuhlinzwa. Uma ukususa i-cataract ngeke kuthuthukise kakhulu umbono, udokotela ohlinzayo nesiguli banganquma ndawonye ukuthi akufanelekile ukuhlinzwa, noma okungenani balinde kuze kube usuku oluthile ukuze babone ukuthi i-cataract iyaqhubeka yini.
Ukuhlolwa kwe-PAM kungasetshenziselwa nezinye izimo lapho ukucaca kwendlela yokukhanya kuwukukhathazeka. Odokotela bangayisebenzisa ukuze bahlole umbono olungiswe kahle kakhulu weziphambeko ezinkulu zokubheka, ama-corneal noma ama-vitreous opacities, igazi elweni, ama-opacities angaphansi kwe-capsular, kanye ne-asteroid hyalosis.
Kwenzekani Ngesikhathi Sokuhlolwa Kwe-PAM?
Ukuhlolwa kwe-PAM akulula kunzima ukufunda ishadi lesiso elijwayelekile.
Izibani zohlu lokuhlolwa zizocwiliswa. Umthamo wamandla we-acuity ungase ubekwe ku-biomicroscope ebizwa ngokuthi isibani sotshani. Ukuphakanyiswa kwesibani sokuqhafaza kusethelwe ekukhuliseni okuphansi kakhulu. Umfundi wakho cishe uzohlanjululwa. Okulandelayo u-opharetha uzofaka isimiso sakho esilinganiselwe seziglasi zakho emshinini. Uzobe ubona ukukhanya bese ubheke ishadi. Izinhlamvu ezibomvu, noma ezihlukile kuneshadi lesiso elijwayelekile. Ukunyakaza kwenhloko ye-Ant kufanele kuncishiswe. Khona-ke uzocelwa ukuba ufunde umugqa omncane kakhulu wezinhlamvu ongabona. Ukuhlolwa kungabuyekezwa izikhathi ezimbalwa ukuqinisekisa imiphumela. Ukuhlolwa kuthatha amaminithi angu-5 kuya kwangu-10 ngeso ngalinye.
Ukulinganisa kwe-PAM Ukulinganisa
Ucwaningo oluningi lubonisa ukuthi imitha engaba khona yocingo ibikezela ubuciko bokubukwa kahle ngaphakathi kwemigqa emibili cishe ngamaphesenti angaba ngu-80-90 weziguli. Okunye ukuhlola kubonisa ukuthi ukuhlolwa kwe-PAM empeleni kufinyelela ekunciphiseni umbono ongcono kakhulu abantu abawutholayo ngakho imiphumela kaningi ingcono kune-test PAM ebikezelwe. E-cataracts kakhulu kakhulu imiphumela ayiyona enembile. Kubalulekile ukuveza ukuthi imiphumela yokuhlolwa kwe-PAM akuvimbeli iziguli ukuba zibe nokuhlinzwa kwe-cataract. Kodwa-ke, kubaluleke kakhulu ukusiza udokotela ohlinzayo ukhethe ukufakelwa kwe-lens intraocular efanele.
Isibonelo, uma ukuhlola kwe-PAM kubonisa ukuthi i-acuity ebonakalayo ingahle ibe yi-20/20, udokotela ohlinzayo akakwazi kakhulu ukusiza isiguli ukhethe ukufakelwa kwe-lens multifocal intraocular lens ngenxa yezindleko ezengeziwe okungenzeka ukuthi isiguli siyakhokhela.
