Laser Iridectomy: ukuthi kuyini, okuthunyelwe-op sikhathi, intengo kanye nokubuyekeza

izifo Ophthalmological kugcwele umhlaba wonke. Ngokuvamile ziseZwini asebekhulile. pathologies Serious engaholela ubumpumputhe, kuyinto glaucoma. Lesi sifo libhekene yokucindezeleka okwandayo ngaphakathi inhlamvu yeso. Enye indlela kokuphatha glaucoma kubhekwa laser iridectomy. It wenziwa ezikhethekile umtholampilo ophthalmologic futhi eziningi eziwusizo kuqhathaniswa ukuvula ukuhlinzwa.

Uyini laser iridectomy

laser Iridectomy - ke inqubo amehlo ukuthi wenziwa ukwehlisa ingcindezi intraocular. Injongo eyinhloko yawo ukungenelela - ukwenza ngcono outflow uketshezi kule uhlaka umbono. Lo msebenzi ukwakha izimbobo ezincane iris esweni. Kukhona izindlela eziningana laser iridectomy. Lezi zihlanganisa:

1. ukusebenza kanye kanye.
2. Isenzakalo esiyingqopha-mlando iridectomy.
3. Layering msebenzi.

iridectomy esisodwa senziwa esebenzisa laser pulsed. Amandla le divayisi MJ 5 kuya ku-15. izicelo Laser lwenziwa izikhathi 1-3. Ngenxa yalokho, kungenzeka ukwakha umgodi ngokusebenzisa e-iris. Buhle le ndlela kuyinto ijubane ekwenzeni lokho okuhleliwe. Yenza iziguli eyodwa esigabeni nge iridectomy kungaba yisiphi wamehlo.

ukusebenza ikhishiwe wenziwa izikhathi. Ngaphezu kwalokho, hlangana laser ukuchayeka iso amasonto 2-3. Ngenxa yalokho, ukwakheka izimbobo iris kusathe gozololo izinyanga eziningana. A ukusebenza efanayo Kwenziwa abantu nokukhanya wamehlo. Okufakwe ukubulawa iridectomy kuyadingeka ukuze ugweme ukuzilimaza ngokwempilo iris mncane nezinye izakhiwo isitho mbono. Amandla laser iyunithi ivela 600 1000 MW, futhi ukuchayeka isikhathi - 0.5 imizuzwana.

iridectomy Egqinsiwe wenziwa abantu nge isiyingi esimnyama seso. Amandla laser kulokhu 1500 MW, nesikhathi ukuchayeka - 0.2 imizuzwana. Imbobo iris kancane kancane ezakhiwe lamellar sombala izicubu ekubhujisweni. Ukuze usebenzise ukusebenza esifushane kangaka-ishayela noma laser Argon.

Izinkomba ukuhlinzwa

Ukuze ulungise outflow uketshezi intraocular, aphethwe iridectomy. imisebe ye-laser kusivumela ukunciphisa ingozi isitho esiphansi. Izinkomba kulo msebenzi izimo ephelezelwa yokujama tsi uketshezi futhi kwandise ingcindezi yokufuna ngaphakathi inhlamvu yeso. Lezi zihlanganisa:

1. Noma okuxubile Ukuvalwa glaucoma.
2. amanani ngokweqile sombala.
3. Anomalies ekamelweni anterior.
4. Pupillary block.

Laser iso iridectomy kwenziwe ngokushesha ukuze zivikele ukuhlaselwa okukhulu glaucoma. High blood pressure kuholela ekulahlekelweni ensimini ezibukwayo futhi ukunciphisa namandla aso. Long ekhona glaucoma simo sengqondo sikaKhayini esiyingozi ubumpumputhe ephelele. Lesi sifo kwenzeka ngenxa nokugcinwa uketshezi phakathi kwegumbi esweni. Kungaba azalwa naso noma bathenga. Esimweni sokuqala, ukufiphala kwamehlo kuwumphumela ukuthuthukiswa okungavamile emzimbeni. Ngazuza waqinisa intraocular kwenzeka nge yansukuzonke isifo ukuvuvukala kanye iziyaluyalu igazi eligciniwe iso. laser Iridectomy siyasebenza ngaphezulu engela-Ukuvalwa glaucoma. Excision sombala igobolondo kuholela ngcono outflow uketshezi esuka egumbini anterior nokucindezelwa ukunciphisa.

Izimo ukwenza iridectomy

Kwezinye izimo, enifeza ukuhlinzwa usebenzisa laser kungamukeleki. Izimo iridectomy zihlanganisa kwale mibandela elandelayo:

1. Ingaphazamisi we-cornea noma lens crystalline (cataract).
2. Ezinganele iris ukujula.
3. edema corneal ezivukayo ngenxa izinqubo ukuvuvukala.
4. Lamabutho retina.
5. Ukungabikho ngeso elilodwa.
6. Nokumnquma-like front ikhamera.
7. Ukukhubazeka we sphincter we umfundi.
8. ukwehla Eqhubekayo Ye-acuity ezibukwayo.
9. Immunodeficiency uthi.

In the ukungabikho Izimo laser iridectomy izikhathi eziningana engenziwa. Isidingo salokhu operation inquma ophthalmologist nangemuva kokwenza ukuhlola ukuthi kungakanani abakwaziyo.

Technique we iridectomy

Laser iridectomy basal Ukwakheka kwezitho kunesikhala yokufakelwa ekhoneni engaphakathi cornea. Kuvumela ukusungula outflow uketshezi esuka egumbini iso anterior kuya ezingemuva. Le nqubo wenziwa ngaphansi izinzwa wendawo. Ngaphezu izidakamizwa analgesic ziyoconsa 1% isixazululo "pilocarpine". Kuyadingeka ukuba unciphise umfundi ngesikhathi kokungenela laser.

Ukuze ukwazi ukufaka isicelo lens iso, okuyinto ikuvumela ukuba wandise Ukubuyekeza yasendle kuhlinzwa. Bese, khetha indawo ukwakha umgodi. It kungenziwa etholakala noma iyiphi ingxenye iris. Akunconyelwe wokubhoboza amahora 12, kusukela kule zoni Bubbles igesi buthelela. Bamehlo uncamela yakha umgodi Crypt zone ezinkulu noma thinning wesabelo iris.

Ugongolo laser lingena lendwangu ngemehlo iso. Lugxile indawo eqondile. Ngo ekhethiwe endaweni laser usebenza ngaphakathi 0.2-0.5 imizuzwana. Ngenxa yalokho, kwakhiwa imbobo ukujula edingekayo. Ukusakazwa ketshezi aqueous is kushintshwe, ngaleyo ndlela kuncishiswe ingcindezi intraocular.

Laser iridectomy: Isikhathi okuthunyelwe-op, imingcele

Ukuze ugweme nemiphumela eyingozi yokusebenza, kubalulekile ukulandela izincomo kudokotela wezifo zamehlo. Kuphela kuleli cala zizosebenza laser iridectomy. isikhathi postoperative ihlala amasonto 2-3. Phakathi nalesi sikhathi, isiguli kumele kuhambisane induduzo ezibukwayo, kanye uyeke ushayela. Ngaphakathi 1 iviki liyadingeka ukuthatha ejenti eqeda ukuvuvukala kanye carbonic anhydrase inhibitor. Lezi zihlanganisa ngeso lehla "Dorzolamide", "Azopt."

Phakathi nenkathi nasezinkingeni ezilandela ngemva kokuhlinzwa kunconywa elaliswa ngomhlane yakhe, futhi ugweme umswakama high (hhayi ukuvakashela obhavu kanye sauna). Amanzi akumelwe siwele iso 1 iviki.

Emihle nemibi amasu

Izinzuzo lokhu indlela yokwelashwa zihlanganisa: okusheshayo impumelelo umphumela bese udala amanzi engokwemvelo amahlaya aqueous phakathi amakhamera iso. Ngaphezu kwalokho, laser iridectomy - inqubo kobuhlungu futhi esheshayo. Ingozi ukopha futhi ukulimala enyameni ezungezile lincishisiwe.

Ububi kubhekwa ukuthi ezinye iziguli bephoqeleka ukuba uhlinzwe futhi ngenxa okuvela ukuvuvukala - ukuvuvukala iris kusayithi emgodini kwakhiwa.

Laser iridectomy: izibuyekezo bamehlo

Bamehlo omuhle mayelana le ndlela yokwelapha, ikakhulukazi uma kuziwa glaucoma ezingeyona inkimbinkimbi. Lapho ayishilo futhi ukwanda okungaqondiswa kwamadolobha kwengcindezi yeso Kunconywa laser trabeculoplasty, noma ukuhlinzwa evulekile.
