Cataract chirwere chinotyisa cheziso, izvo zvinowanzotungamirira kupofu. Nzira chete inobatsira yekurapa chirwere ndechokubvisa nzvimbo dzakakomberedzwa dzero, izvo zvamira kurega kuita mabasa avo, uye kuisa panzvimbo yavo iyo lensicular intraocular lens. Kutanga kurapwa kwakagadzirwa mumugwagwa unogadziriswa, zvino phacoemulsification ye cataract nekuiswa kweIOLs iri kuwedzera kushandiswa, seimwe nzira yemazuva ano uye yemazuva ano.
Chii chinonzi phacoemulsification yehutachiona nekumiswa kwemajeni emukatikati?
Chinokosha chekushanda uku ndiko kupwanya uye kubviswa kwemafu (akafuridzirwa) nzvimbo dze lens. Panzvimbo yezvinhu izvi zvisingaiti, nzvimbo inogadziriswa inosungirirwa - inotapira inowanikwa mukati mekudzivirira kwemavara. Iine chiyeuchidzo chemafomu uye inotora zvakakwana mabasa emarara yakakonzerwa.
Ndeipi nzira ye ultrasound phacoemulsification ye cataract nekuiswa kweIOL?
Kuenzanisa kwezviito panguva yekuvhiyiwa:
- Local anesthesia.
- Kuitwa pamwe chete nechepamusoro pemakorome ekukona kusvika 2 mm murefu.
- Nhanganyaya yechirongwa che ultrasound mukamuri remukati yeziso.
- Kuvhara kwemazuva matatu kweevcoelastic kudzivirira maziso eziso mukati.
- Kugadzirwa kwechinyorwa pane capsule ye lens.
- Kupwanya uye kushanduka kwehutukuro mu emulsion.
- Kubudirira kwekuvhiringidzika kwemajisi lens.
- Nhepfenyuro kuburikidza nekukanganiswa pamusoro wekasivha yeIOL inoshanduka, yakambove yakapetwa nenzira yehutu.
- Shambai viscoelastic kubva muimba yekare yeziso nezveseri yekudiridza.
Yakaputika mukati memasocular lens, ichipinda mumutambo we lens, yakananga ikoko pachazvo, ichiwana chimiro chakanaka uye chakagadzirirwa zvakachengeteka.
Zvakakosha kuziva kuti, zvichienderana nekukwirira kwemaikisiko ekukanganiswa kwekromaa, hapana kukwezva kunodiwa mushure mekushanda. Nokudaro, nguva yekudzikinura inotora nguva shoma, uye kazhinji, kupindira kwekuvhiya hakusi kushungurudza.
Zvinetso zvepecoemulsification yehutachiona neIOL inogadzirwa
Migumisiro inogona kuitika yebasa racho:
- kukanganisa kumiromo;
- kusununguka kweIOL;
- third-party injection of the cornea from ultrasound;
- kupera kwe capsule ye lens;
- kurasikirwa kwemavreous body.
Zvakakosha kuyeuka kuti njodzi yezvinetso zvinotarisana zvakananga nebasa rechiremba.
