Ukuhlinzwa Kwe-Astigmatism

• Kwenziwa kanjani ukuhlinzwa
• Izingozi zokuhlinzwa

Ukuhlinzwa kwe-astigmatism kungenye yezindlela eziphumelela kakhulu zokwelapha i-astigmatism, njengoba kuvumela ukuncika okuncane kwizingilazi noma kuma-lens, ngaphezu kokulungiswa okuphelele kwezinga umuntu abenalo. Yazi izimpawu ze-astigmatism.

Yize kungenzeka ukuthi kwelashwe i-astigmatism ngalolu hlobo lokuhlinzwa, kuyadingeka ukuthi kwenziwe ukuhlolwa nodokotela wezifo zamehlo ngaphambi kwenqubo njengoba kudingekile ukuba nezimo ezithile ngaphambi kokuhlinzwa, njengokuthola uketshezi oluminyene ngokwanele, ukuba nombono ozinzile noma, ngokuvamile, ukuba ngaphezu kweminyaka engu-18, ngokwesibonelo.

Kwenziwa kanjani ukuhlinzwa

I-Astigmatism ingalungiswa ngokuhlinzwa, okuvame ukukhonjiswa kubantu abaneminyaka engaphezu kwe-18 ubudala noma abaneziqu zabo ezizinzile cishe unyaka owodwa. Ukuhlinzwa kwenziwa ngaphansi kwe-anesthesia yendawo futhi kuvame ukuhlala cishe imizuzu engama-20, kepha isikhathi singahluka ngokuya ngohlobo lokuhlinzwa olunconywe ngudokotela wezifo zamehlo.

Izinhlobo zokuhlinzwa ezisetshenziselwa kakhulu i-astigmatism zifaka:

• Ukuhlinzwa kwe-LASIK: Kulolu hlobo lokuhlinzwa, kusikwa i-cornea bese i-laser ifakwa ngqo esweni ukushintsha ukwakheka kwe-cornea, okuvumela ukwakheka okulungile kwesithombe nokugwema umuzwa wokuphindaphindeka nokuntuleka kokucaca. Imvamisa ukululama kuhle kakhulu futhi ukulungiswa kwezinga kuyashesha kakhulu. Qonda ukuthi ukuhlinzwa kwe-LASIK kwenziwa kanjani.
• Ukuhlinzwa kwePRK: Kulolu hlobo lokuhlinzwa, i-corneal epithelium (ingxenye engaphezulu kakhulu ye-cornea) isuswa ngensingo bese kusetshenziswa i-laser ngaphezulu kweso. Ngemuva kwalokho kusetshenziswa ilensi yokuxhumana ukuvimbela ubuhlungu esikhathini sangemva kokuhlinzwa. Isikhathi sangemva kokuhlinzwa kwalokhu kuhlinzwa siside futhi isiguli singathola ubuhlungu, kepha kuyindlela ephephile ngokuhamba kwesikhathi. Funda kabanzi ngokuhlinzwa kwe-PRK.

Intengo yokuhlinzwa kwe-astigmatism ingahluka ngokuya ngohlobo lokuhlinzwa nendawo lapho inqubo izokwenziwa khona, futhi ingahluka phakathi kuka-R $ 2000 no-R $ 6000.00 ngeso ngalinye. Ukuhlinzwa, noma kunjalo, kungabiza uma kufakwa ohlelweni lwezempilo.

Izingozi zokuhlinzwa

Yize kungenzeki njalo, ukuhlinzekwa kwe-astigmatism kubeka izingozi ezithile, njenge:

• Ukwehluleka ukulungisa inkinga ngokuphelele, kudinga ukuthi umuntu aqhubeke nokugqoka izibuko noma amalensi okuxhumana;
• Ukuzwela kweso elomile ngenxa yokuncipha kokuthambisa kweso, okungadala ukubomvu nokungahambi kahle;
• Ukutheleleka esweni, okuhlobene kakhulu nokunganaki ngemuva kokuhlinzwa.

Ezimweni ezinzima kakhulu, ukungaboni kungasenzeka ngenxa yokutheleleka kwe-corneal, kepha-ke, lokhu kuyinkinga engajwayelekile futhi kungagwenywa ngokusetshenziswa kwamaconsi wamehlo esikhathini sangemva kokuhlinzwa. Kodwa-ke, udokotela wamehlo akakwazi ukuqinisekisa ukuthi ayikho ingozi yokutheleleka. Yazi izinhlobo zamaconsi wamehlo nokuthi enzelwe ini.
