Kusuruvara kwakajairika pakati pevanhu vakwegura, nekuvhiyiwa kwekataract kuva imwe yenzira dzakachengetedzwa dzakachengetedzwa dzakaitwa pakati peAmerica. Kana uri kutsvaga kurapwa kwehutachiona, ungave uchifarira chirwere chemalasi cataract.
Kuvhiyiwa kwekatarita yemagariro kunopedzerwa uchishandisa jira duku rekudzidzira kwekutanga, rinoteverwa nenzira inotungamirirwa ne phacoemulsifier.
A phacoemulsifier isimbi inonzi ultrasound iyo inodedera pamusorosoro wakadaro iyo cataract iri emulsified kana kuputika muzvimedu zviduku uye zvakanyatsotorwa kubva muziso.
Muna 2011, Zvokudya uye Drug Administration zvakapa mvumo kune makambani akawanda emashini ekurapa chirwere checataract, chinonzi femtosecond laser cataract surgery.
Traditional Versus Laser Cataract Surgery
Pakati pekuvhiyiwa kwechirwere chechirwere, kudonhedzwa kuduku kunowanikwa muhutachiona hwekornea . Iko kunogadzirwa kunoitwa nesimbi kana dhaimani tsvina yakaitwa nachiremba. Izvi zvinosungirirwa kuvhara zvinenge 2 kusvika ku2,5 mm kure uye zvine zvishoma zvishoma uye zvisinganzwisisiki chikamu kuitira kuti zvidimbu zvirege kudiwa.
Mukuvhiya kwema-cataract, nevakadzi femtosecond, chiremba anokwanisa kuona mufananidzo wakakurumbira, wakagadziriswa wakapiwa kwaari nechikwata cheOCT chakavakwa. A incipiral incision inogona kuve yakarongeka pasina kutora chiitiko chechiremba.
Izvi zvinonzi laser-designed incision ndezvokuchengeteka uye zvisimbiso zviri nani kupfuura chiremba chinogadzirwa nechiremba.
Chikamu chinotevera chechipatara chechipatara chirwere ndicho capsulotomy. Munguva yecsulotomy, chiremba anovhima mutsara muduku mukati mechikamu chekutanga che lens capsule inobata lens uye cataract. Kururama kwechikamu ichi chekuvhiya kunogona kusiyanasiyana kubva kuchiremba uye chiremba wechiremba sezvo kunyatsotaridzika kwekodsulotomy kunoenderana nechiitiko chechiremba.
Chiremba anovhiya achagadzira mukova uyu nekushandisa nheyo kubvarura gomba duku mu capsule. Chiremba uyo achazoshandisa forceps kuti adzore denderedzwa kusvika mberi kwemukati we capsule. Ichi chikamu chakakosha chekuvhiyiwa nokuti capsule yekare icharamba yakabata mitsva inopinza kana yemazino epraocular, iyo inowanikwa muziso kuitira kuti ichinese chinetso chekare chekare-cataract.
Mune chirwere chemalasi cataract, chirwere chinonzi capsulotomy chinoshandiswa mumutambo wakazara wakakwana uye yakasununguka zvizere nechiremba. Izvi zvinenge zvichitenderedzwa zvinogona kuve zvakanyatsotarisana kuti zvigadzire mutsara wekuvhara mutsva panzvimbo.
Kamwe iyo inonzi capsulotomy inowanikwa mukuvhiya kwechirwere chechipatara, chiremba anovhiya anoshandisa chipambo che phacoemulsifier chinoshandisa super-speed ultrasound kuti iparadze cataract muzvidimbu zviduku, izvo zvino zvichinyatsotorwa.
Nekadzi femtosecond laser, lens rinoputsika kuita zviduku zvishoma seine phacoemulsifier. Kubudirira kwekushandisa laser ndeyekuti simba rakawanda rinopinda mukuputsa cataract kunze, nokudaro kuderedza zvinetso zvingaita, zvakadai sokuputsa zvisiri izvo capsule, kana kuti zvinetso zvakanyanya, zvakadai sekubuda ropa kana kuti retinal detachment.
Nhanho inotevera mumutambo we cataract ndeyekuisa itsva inonzi intraocular lens implant kuti ishandise mutero wakambobviswa.
Muvarwere vazhinji, simba rakarongerwa rekutsvaira kwemazuva ano inoedza kuderedza kudiwa kwomurwere kupfeka magirazi nokuda kwemabasa akawanda ekufamba shure mushure mekuvhiyiwa. Kana munhu anenge achivhiyiwa ari pedyo kana kuti ari kutarisa, iyo inogadziriswa yemero inobhadharisa chirevo ichocho.
Dzimwe nguva, astigmatism yakasara ichabuda, zvichikonzera zvishoma pane zvaidiwa zviratidzo mushure mekuvhiyiwa. Vanachiremba vazhinji vanovhima vachaita zviduku zvishoma vachishandisa blade kuti vatsigire reastigmatism rekugara. Kamwe zvakare, ine laser, yakarurama, yakanyanya kuiswa, laser-induced incisions inogona kuitwa mukuedza kubvisa astigmatism.
Inonzi Laser Cataract Surgery Zviri nani Here?
Kuvhiyiwa kwechirwere chechipatara kunoramba iri nzira yakachengeteka uye inobudirira. Vakawanda vanachiremba vanotenda kuti chirwere chemalasi cataract ndiyo chokwadi danho rinotevera rekuvandudza kusachengetedzwa uye zviitiko zvevanhu vane chirwere checataract. Vakawanda vanoita chirwere chechipatara vanofunga kuti pakupedzisira chirwere checataract chichaitwa kuburikidza ne laser.
Nhasi, chirwere chinonzi cataract chirurgic chingangovheneka zvakajeka mukutanga multifocal kana kuti presbyopia-kugadzirisa kushandiswa kwekugadzira kurapwa. Izvi zvinonzi premium multifocal implants dzinoderedza kuderedzwa kwemashure ekugadzirisa magirazi ekugadzirisa magirazi kuburikidza nekugadzirisa matambudziko ekuona zvishoma chete asiwo pakati nepakati pedo kuona. Izvi zvinogadzirirwa kuita kuti murwere aite chete magirazi emaziso pane zvishoma. Urwu urwu hwekuvhiya hunoda kunyatsoona, saka femtosecond laser.
Kurwisa kweAraer Cataract Surgery
Chimwe chezvipingamupinyi zvishomanana zvekuvhiya chirwere chemahara chinokonzera kukonzera. Vanhu vanowanzoita maitiro emasero vanowanzowedzera kubwinya kwezuva mushure mekuvhiyiwa, nemhaka yekuita kwechiridzwa panguva yekuvhiyiwa.
Chipiri chekuvhiringidza kunodhura. Maitiro emaserasi ayo anowanikwa ikozvino FDA-anobvumidzwa nekuvhiyiwa kwecataract inodhura chiremba wevhiya chero kupi zvako kubva $ 400,000 kusvika ku $ 500,000 kutenga. Vanachiremba dzimwe nguva vanonetseka nepfungwa yokuti kunyange zvazvo teknolojia itsva ingangova nani kune dzimwe nzvimbo, kuwedzerwa kukuru kwebhadharo kunogona kunge kusingabatsiri murwere kana utano hwehutano huzhinji. Hazvina mubvunzo kuti Medicare nemakambani einishuwarenzi achavhara nzira yacho.
Chechitatu, kunyange zvazvo nhanho imwe neimwe yemararamiro emarara inenge yakachengeteka, iyo yose nzira yacho pachayo inotora nguva yakareba, kuwedzera njodzi yezvinetso kana utachiona. Mumaoko ane ruzivo rwechirwere chechirwere, chirwere chechipatara chechipatara chinogona kutora zvishoma semaminitsi gumi nemaminetsi gumi nemashanu ekuvhiya chaiyo pachake, uye chirwere chemalasi chinotora nguva yakareba.
