I-Cataract isifo esiyingozi kwiso, edla ngokukhokelela ekugqibeleni ukuphosa. Indlela efanelekileyo yokuphulukisa i-pathology kukuba kususwe iindawo ezixhambileyo ze-lens, eziye zayeka ukwenza imisebenzi yazo, kwaye zifaka endaweni yazo i-lens intraocular lens. Ulwaphulo oluphambili lwamayeza lwenziwa kwinqanaba le-tunnel yomsebenzi, ngoku i-phacoemulsification ye-cataract ngokufakelwa kwe-IOL iyasetyenziswa ngokuphindaphindiweyo, njengendlela ekhoyo yangoku kunye ne-hi-tech.
Iyintoni i-phacoemulsification ye-cataracts kunye nokufakelwa kwe-lens intraocular?
Ingundoqo yolu msebenzi kukutyunjwa nokususwa kweendawo ezifihliweyo (i-clouded) ze-lens. Endaweni yale mimandla engasebenziyo, ukufakelwa kufakelwe - i-lens intraocular yokufakelwa kwintsimbi. Inememori yefom kwaye iyithatha ngokupheleleyo imisebenzi yelensi ewonakele.
Iyintoni inkqubo ye-ultrasound phacoemulsification ye-cataract ngokufakelwa kwe-IOL?
Ukulandelelana kwezenzo ngexesha lotyando:
- Anesthesia yendawo.
- Ukuphunyezwa ngaphaya komda we-cornea incision ukuya kwi-2 mm ubude.
- Isingeniso sefowuni ye-ultrasound kwikamelo langaphakathi lelihlo.
- Ukujova ngokufanayo ngexesha le-viscoelastic ukukhusela izakhiwo zamehlo zangaphakathi.
- Ukuqulunqwa kwenotshi kwi capsule yelensi.
- Ukuchithwa nokuguqulwa kwe-turbidity kwi-emulsion.
- Ukuphumelela kwezicubu zentsholongwane ezilimele.
- Isingeniso ngokubakho kwi-capsule ye-IOL eguquguqukayo, ngaphambili ixutywe ngendlela ye-tube.
- Geza i-viscoelastic kwikamelo elingaphandle kweso ngelixa isisombululo sokunkcenkceshela.
I-lens intraocular ehlahliweyo, ukungena kwi-lens cavity, iqondisa apho ngokuzimeleyo, ukufumana isimo esifanelekileyo kunye nokulungisa ngokukhuselekileyo.
Kubalulekile ukuba uqaphele ukuba, ngenxa yobungakanani bemilinganiselo ye-incision kwi-cornea, akukho suturing iyadingeka emva kokusebenza. Ngako oko, ixesha lokubuyisela lithatha ixesha elincinci, kwaye ngokubanzi, ukungenelela okutyathwayo akuyona ingxaki.
Iingxaki ze-phacoemulsification ye-cataract ne-IOL implantation
Imiphumo ekhoyo yokusebenza:
- umonakalo wegament ligament;
- ukufuduka kwe-IOL;
- Ukulimala okwesithathu kwe-cornea kwi-ultrasound;
- ukuphuka kwe-capsule ye-lens;
- ukulahleka komzimba.
Kubalulekile ukukhumbula ukuba umngcipheko weengxaki zixhomekeke ngqo kwizakhono zobugqirha.
