Secondary cataract lens esikhundleni emva kokwelashwa kanye nokubuyekeza

kuyaqina Inherent we capsule lens. Phakathi ukuhlinzwa cataract lens intraocular ibekwe esweni ukuze ufakele enye. Kulesi capsule posterior isekela entsha lens intraocular. Kwenzeka ukuthi capsule siqala ukushintsha esinamafu, elibangela lo mkhuba cataract yesibili ngemva lens esikhundleni. Ukwelashwa, okuyinto libuyekeza omuhle kakhulu, kwenziwa ngokuhambisana ubufakazi bezokwelapha. Sebenzisa izindlela zakamuva futhi imishini eliphezulu.

Izimbangela lomkhuba

Lapho kukhona cataract yesibili ngemva esikhundleni lens? Uphenyo odokotela ngalokhu inkinga zisikisela ukuthi izizathu eqondile ivela khona kungukuthi kudalulwe.

Ukuthuthukiswa yezinkinga yesibili kungenxa ekukhuleni epithelium, owenziwe waba owasendaweni phezu kobuso capsule posterior. Kungukuphula ngale, okubangela umbono kwehle. inqubo enjalo ngeke kukhonjwe yephutha we udokotela ohlinzayo ngesikhathi ukusebenza. cataract yesibili ngemva esikhundleni lens, izimbangela zazo amanga ukusabela komzimba emangqamuzaneni kusehlakalo sasivumela njalo. Lens EPITHELIAL amaseli ibe Imicu yotshani ukuthi bayakwazi onesici, abangaphumi njalo ukuma kukhona opaque. Lapho beyikhipha kungxenye lemcoka zone optic ophakamayo ingaphazamisi. angaboni kahle kungase kubangelwe izinkinga cystic we capsule.

engcupheni

Bamehlo basungula tintfo letichaza kutsi kungani kukhona cataract yesibili ngemva esikhundleni lens. Abakwazi ubalwe njengenye elandelayo:

• yobudala wesiguli. Esengumntwana cataract emva kokuhlinzwa kwenzeka kaningi. Lokhu kungenxa yokuthi asesibelethweni umzimba abasha babe nekhono okusezingeni eliphezulu yokuvuselela esibangela yokufuduka amaseli EPITHELIAL nokuhlukanisa bangene capsule posterior.
• Ubujamo Isolezwe. Isolezwe ukuma square ivumela isiguli ukuba kakhulu ukunciphisa ingozi yokulimala.
• Material Isolezwe. Odokotela bathola ukuthi emva kusungulwa IOLs acrylic esekelwe cataract yesibili kwenzeka kancane njalo. ukwakhiwa Silicone avuse ukuthuthukiswa yezinkinga ziyinsakavukela ngaphezulu.
• Ukuba khona ngesifo sikashukela, kanye ezinye izifo jikelele futhi amehlo.

izinyathelo

• Eliphucuziwe lens capsule ukuze wandise ukususwa amaseli.
• Khiqiza ezihlukahlukene izakhiwo eziklanyelwe.
• imithi ezisetshenzisiwe ngokumelene ulwelwesi esweni. Wangcwatshwa lapho ncamashi njengoba kushiwo ku-iso.

Izimpawu ze-cataract yesibili

Ngo kusaqalwa cataract yesibili ngemva esikhundleni lens ngokuvamile abakwazi ukuzibonakalisa. Isikhathi sokuqala ekuthuthukiseni lesi sifo kungaba isukela eminyakeni 2 kuya ku-10. Khona-ke baqala ukubonisa izimpawu ezisobala, kanye nokulahlekelwa into umbono. Kuye ngalokho lens ensimini ukusonteka eyenzekile, isithombe emitholampilo ye isifo ingahluka kakhulu.

Uma inkinga yesibili ukuvela azungeze lens, kungenzeka zibangele Ukuwohloka umbono. Njengoba umthetho, zokugula itholakala ku luhlolo lohleliwe ngu kudokotela wezifo zamehlo.

Kanjani lokhu kuzibonakalisa inqubo sokugembula njengoba cataract yesibili ngemva esikhundleni lens? Ukwelashwa (izimpawu neluhlolo ahlobene kufanele uqinisekise uphethwe) kuboniswa ngenxa iconsi ziphikelele acuity ezibukwayo, ngisho bacabanga bona lakhiwa kabusha ngokuhamba ukuhlinzwa. Okunye ukubonakaliswa zihlanganisa khona indwangu, ukubukeka wokhela nge kwelanga noma ukukhanya imithombo yokufakelwa.

Ngaphezu izimpawu ngenhla, kungase kube monocular yokuhlukanisa izinto. I eduze maphakathi lens anyakaza, le sibi umbono isiguli. ngwengwezi Secondary angagcina njengasencwadini iso, futhi bobabili. Kubonakala angahleliwe kombala, ukuthuthukisa myopia. izimpawu kwangaphandle kungukuthi ngokuvamile baphawula.

ukwelashwa

cataract yesibili ngemva esikhundleni lens, yona ukwelashwa wenziwa ngempumelelo emitholampilo yesimanje amehlo isuswe ngu capsulotomy. Lokhu zokukhwabanisa kusiza ukukhululwa kwe-zone lemcoka ufasimbe yokukhanya ivumela imisebe yokukhanya ukuwela iso, kakhulu ngcono ikhwalithi umbono.

Capsulotomy wenziwa njengoba (zomculo ezazisetshenziswa) mechanical, futhi indlela laser. Indlela yokugcina kunezinzuzo ezinkulu ngoba ayidingi ukwethulwa insimbi kuhlinzwa phakathi komgodi iso.

kokungenela kuhlinzwa

Njengoba aqedwa yesibili cataract lens? Ukwelashwa kuhilela ukuhlinzwa. Lokhu kuhlinza kuhilela imbobo noma excision we ifilimu opaque esebenzisa ummese kuhlinzwa. Izikhundla is kuboniswe endabeni lapho cataract yesibili lapho shift lens iye yabangela yezinkinga ezinkulu, futhi kukhona amathuba ukuthi isiguli ngeke impumputhe.

Phakathi ukusebenza kwenziwa imbobo cruciform. Okokuqala enza ku Iwumbono eksisi ezibukwayo. Ngokuvamile, imbobo has a ububanzi of 3 mm. Kungase ube isilinganiso enkulu uma kunesidingo hlola phansi amehlo akho noma zidinga photocoagulation.

ukuhlinzwa nebubi

indlela Steel usetshenziswa njengesibonelo abadala kuqhathaniswa nezingane ngokufanayo. Nokho, i-operation kahle elula linenani yokuntula abalulekile ezihlanganisa:
