I-Keratoscopy, ebizwa nangokuthi i-corneal topography noma i-corneal topography, ukuhlolwa kwe-ophthalmological okusetshenziswa kakhulu ekutholeni i-keratoconus, okuyisifo esiwohlokayo esibonakala ngokuguquguquka kwe-corneal, esigcina sithola ukwakheka kwesigaxa, ngobunzima ekuboneni nasekuzweleni okukhulu ekukhanyeni.

Lokhu kuhlolwa kulula, kwenziwa ehhovisi le-ophthalmology futhi kuqukethe ukwenziwa kwemephu ye-cornea, okuyizicubu ezisobala eziphambi kweso, okukhomba noma yiziphi izinguquko kulesi sakhiwo. Umphumela wesimo sendawo esimenyezelayo ungakhonjiswa ngudokotela ngemuva nje kokuhlolwa.

Yize isetshenziswe kakhulu ekutholeni i-keratoconus, i-keratoscopy nayo yenziwa kabanzi esikhathini sokuqala nasemva kokuhlinzwa kokuhlinzwa kwamehlo, okukhombisa ukuthi ngabe umuntu uyakwazi yini ukwenza inqubo nokuthi inqubo inomphumela olindelekile yini.

Isimo sendawo seCorneal senziwa ukukhomba ushintsho ebusweni be-corneal, senziwa ikakhulu:

• Linganisa ukushuba nokugobeka kwe-cornea;
• Ukuxilongwa kwe-keratoconus;
• Ukukhonjwa kwe-astigmatism ne-myopia;
• Hlola ukuguquguquka kweso kwelensi yokuxhumana;
• Hlola ukonakala kwe-corneal.

Ngaphezu kwalokho, i-keratoscopy yinqubo eyenziwa kabanzi esikhathini sokuhlinzwa sokuhlinzwa okukhanywayo, okuwukuhlinzwa okuhlose ukulungisa ushintsho ekudlulisweni kokukhanya, kepha akubona bonke abantu abanezinguquko ku-cornea abakwazi ukwenza inqubo., njengoba kunjalo ngabantu abane-keratoconus, ngoba ngenxa yesimo se-cornea, abakwazi ukwenza lolu hlobo lokuhlinzwa.

Ngakho-ke, esimweni se-keratoconus, udokotela wezifo zamehlo angancoma ukusetshenziswa kwezingilazi zikadokotela kanye namalensi athile othintana nawo futhi, ngokuya ngezinga loshintsho ku-cornea, angakhombisa ukusebenza kwezinye izinqubo zokuhlinza. Qonda ukuthi ukwelashwa kwe-keratoconus kwenziwa kanjani.

Isimo sendawo saseCorneal singenziwa nangemva kwesikhathi sokuhlinzwa, kubalulekile ukuqinisekisa ukuthi ngabe ukulungiswa kulungisiwe nokuthi yini imbangela yokungaboni kahle ngemuva kokuhlinzwa okwenziwe ngenkani.

Kwenziwa kanjani

I-Keratoscopy inqubo elula, eyenziwa ehhovisi le-ophthalmologic futhi ihlala phakathi kwemizuzu emi-5 nengu-15. Ukwenza lesi sivivinyo akudingekile ukuthi kube nokuvuleka komfundi, ngoba ngeke kuhlolwe, futhi kunganconywa ukuthi lowo muntu angawagqoki amalensi wokuxhumana ezinsukwini ezimbili kuya kwezi-7 ngaphambi kokuhlolwa, kepha lokhu kuncoma kuncike ukuma kukadokotela nolensi wohlobo osetshenzisiwe.

Ukwenza ukuhlolwa, lo muntu ubekwe kudivayisi ekhombisa amasongo wokukhanya amaningi, aziwa njengezindandatho zePlacido. I-cornea ukwakheka kweso elibhekele ukungena kokukhanya futhi, ngakho-ke, ngokuya kwenani lokukhanya okukhanyayo, kungenzeka ukubheka ukugobeka kwe-cornea bese ubona izinguquko.

Ibanga phakathi kwamasongo okukhanya abonisiwe liyalinganiswa futhi lihlaziywe yisoftware kukhompyutha ehambisana nemishini. Yonke imininingwane etholakele ekuphumeni kwamasongo wokukhanya ithathwa ngohlelo futhi iguqulwe ibe yimephu yombala, okumele ihunyushwe ngudokotela. Kusuka kwimibala ekhona, udokotela angabheka ushintsho:

• Okubomvu ne-orange kuyinkomba yokugobeka okukhulu;
• Okuluhlaza okwesibhakabhaka, okuluhlaza okwesibhakabhaka noluhlaza kukhombisa ukuthi ama-curve curter

Ngakho-ke, uma imephu ibomvu ngokusawolintshi ngokwengeziwe, kukhula ushintsho ku-cornea, okukhombisa ukuthi kuyadingeka ukwenza ezinye izivivinyo ukuqedela ukuxilongwa bese kuqala ukwelashwa okufanele.
