Indlela olwenziwa ngayo unyango lwekati

Umxholo

• 1. Ukunxiba iilensi okanye iiglasi
• 2. Ukusetyenziswa kwamehlo
• 3. Utyando
• Utyando lwestem cell cataract

Unyango lwe-cataract lwenziwa ikakhulu ngotyando, apho ilensi yamehlo ithathelwa indawo yilensi, evumela umntu ukuba abuye abone kwakhona. Nangona kunjalo, ezinye i-ophthalmologists zinokucebisa ngokusetyenziswa kwamehlo, iiglasi okanye iilensi zonxibelelwano de kwenziwe utyando.

I-Cataract sisifo esiveliswa kukuwohloka kwelensi yamehlo, esikhokelela ekuphulukaneni nombono, onokuthi uhambelane nokuguga okanye izifo ezinganyangekiyo, ezinje ngesifo seswekile kunye ne-hyperthyroidism, umzekelo. Funda ngakumbi malunga ne-cataract, oonobangela kunye nendlela yokufumanisa isifo.

Unyango lwe-cataract kufuneka luboniswe ngugqirha ngokobudala bomntu, imbali yezempilo kunye nenqanaba lokukhubazeka kwelensi yamehlo. Ke, unyango olunokucetyiswa ngugqirha wamehlo zezi:

1. Ukunxiba iilensi okanye iiglasi

Ukusetyenziswa kweelensi zoqhakamshelwano okanye iiglasi zokumiselwa kunokuboniswa ngugqirha kuphela ngenjongo yokuphucula ukubonwa komntu, kuba oko akuphazamisi ukuqhubela phambili kwesi sifo.

Eli nyathelo liboniswe ikakhulu kwiimeko apho esi sifo sisesekuqaleni, kungekho sikhombisi sotyando.

2. Ukusetyenziswa kwamehlo

Ukongeza ekusebenziseni iilensi zonxibelelwano okanye iiglasi zamehlo, ugqirha usenokubonisa nokusetyenziswa kwethontsi lamehlo elinokunceda ukunciphisa ubuntununtunu bamehlo. Kukwakho neliso elirhawuzayo elibonayo elinokuthi lithathe amanyathelo okulibazisa ukukhula kwesifo kwaye "lichithe" isifo samehlo, nangona kunjalo olu hlobo lwethontsi lamehlo lisaqhutywa ukuba lilawulwe kwaye likhutshwe ukuze lisetyenziswe.

Bona ulwazi ngakumbi malunga neentlobo zamehlo.

3. Utyando

Utyando kuphela kwonyango lwengxangxasi olunakho ukukhuthaza ukubuyiswa kwembonakalo yomntu, kubonisiwe xa ilathalala sele likwinqanaba eliphambili. Utyando lweCataract luhlala lusenziwa phantsi kwe-anesthesia yendawo kwaye lunokuhlala phakathi kwemizuzu engama-20 kunye neeyure ezi-2 kuxhomekeke kubuchule obusetyenzisiweyo.

Nangona utyando lwe-cataract lulula, lusebenza kwaye alunabungozi obunxulumene noko, kubalulekile ukuba ezinye iingcebiso zilandelwe ukubuyisela kwimeko yesiqhelo ngokukhawuleza, kwaye nokusetyenziswa kwamehlo okuthintela usulelo kunye nokudumba kunokucetyiswa ngugqirha. Fumanisa ukuba lwenziwa njani uqhaqho lwamehlo.

Utyando lwestem cell cataract

Kuba iingxaki zoqhaqho zixhaphake ebantwaneni, uqhaqho olutsha luyaphuhliswa ukuze kunyangwe ngokuqinisekileyo amatyala wesifo sokuzalwa komntu ngaphandle kokufaka ilensi yendalo yamehlo ngento engeyiyo.

Obu buchule butsha buquka ukususa zonke iilensi ezonakeleyo esweni, kushiyeke kuphela iiseli zeziqu ezakhokelela kwilensi. Iiseli ezihlala elisweni ziyavuselelwa kwaye zikhule ngesiqhelo, zivumela ukwenziwa kwelensi entsha, yendalo kunye nebala ebonakalayo, ebuyisela umbono ukuya kuthi ga kwiinyanga ezi-3 kwaye ayinabungozi bokubangela iingxaki kwiminyaka edlulileyo.
