Tsanangudzo: Phacoemulsification ndiyo inowanzoshandiswa pakuvhiya chirongwa chakaitwa. Kuvhiyiwa kweCataract kunoshandiswa kugadzirisa zviratidzo mune varwere vane zviratidzo zvave zvichitonhora kubva kune cataract , a clouding ye lens yeziso.
Iyo lens iri seri kweIris. Icho chinotarisirwa kuisa chiedza pa retina, uye nekugadzira mifananidzo yakajeka, yakajeka. Iyo lens ine simba rekuchinja maitiro, inozivikanwa sekugara .
Sezvo meso akakura, zvisinei, lens iri rakaoma uye rinorasikirwa nekwanisiro yekubata. Ikose iyo yose iri mukati memusoro we lens. Sezvo maziso aripo, hutachiona hunoitika uye masero akafa anounganidza mumakumbo e-lens, zvichiita kuti lens iri zvishoma nezvishoma rive denga. Chiedza chinowanzotariswa ne-lens chakapararira kumativi ose nekuda kwegore, saka maonero haasisiri akajeka uye akajeka.
Ko phacoemulsification inoitwa sei?
Munguva yepa phacoemulsification, chiremba anovhiya anoita zviduku zvishoma pamugumo wekorne uye zvino anogadzira kuvhura mu membrane inopoteredza lens. Shanduro shomanana ye ultrasonic inowedzerwa, kuputsa masikati machena muzvikamu zviduku. Chimbo chacho chinodedera pa ultrasonic speed kukuma uye inoda kuparara kwemazipa emarara muzvikamu zviduku. Zvimedu izvi zvinobva zvabudiswa kunze kwe capsule nechibatanidza pane probe tip.
Mushure mokunge lens particles zvabviswa, intraocular lens implant, inowanzonzi iIOL, inoshandiswa uye yakagadzirirwa mu lens yemashupusi.
Inosungirirwa kuburikidza nediki duku rinokonzerwa nekodeni kuburikidza nehuputi yakabuda. Kamwe kacho lensi yacho inoputirwa, inobuda uye inoiswa panzvimbo.
Phacoemulsification inowanzoitwa muchipatara chekuvhiya kunze uye kazhinji haidi kuti chipatara chigare. Iro chirwere chekuchera chirwere chinoshandiswa pasi peanesthesia yepamunharaunda (anesthetic injected pedo neziso) kana temaini anesthesia (numbing maronta akaiswa muziso).
Ndeipi nguva yekudzikinura yepa phacoemulsification?
Iyo yakagadzirwa mu cornea kazhinji inoda kuti zvive zvakasungwa uye kuzvivhara. Mumazuva mashomanana, incision inoporesa zvachose. Maziso emashure anonzi Post-operative anorayirwa uye anowanzomira ane antibiotics, steroids, uye isiri-steroidal anti-inflammatory medication. Madonhwe aya anoderedza kupisa uye kudzivirira utachiona. Mishonga inorwisa mabhakitiriya inowanzomira mukati memazuva manomwe. Itero steroid uye kwete-steroidal anti-inflammatory inotorwa pamasvondo matatu kusvika matanhatu zvichienderana nekuvhiyiwa. Vakawanda varwere vane huono hwekuona zvishoma nenguva uye chiratidzo chinowedzera kuwedzera zvishoma pamasvondo mana kusvika ku5.
Phacoemulsification yakashandura chirwere checataract. Pamberi pekugadziriswa kwepamusoro kwakagadzirwa, vanachiremba vanovhiya vaizobvisa lens rose uye capsule. Izvi zvakaita kuti zvive zvakaoma kuisa lens intraocular. Ikopa reziso rinowedzera simba rekutarisa kune ziso. Somugumisiro, kana iwe ukabvisa cataract, iyo inonzi lens, murwere anasiyiwa nepamusoro-soro "pamwe," mutsara wepamusoro. Ichi ndicho chikonzero, makore mazhinji akapfuura, apo varwere vaiva nemakumbo akabviswa, ivo vaipfeka "cataract magirazi." Cataract magirasi akanga akaoma, akaremara uye akakudza maziso.
Hazvina nguva refu vanachiremba vakaziva kuti vaida nzira iri nani yekuisa lens implant kuitira kuti varwere vasazofanira kupfeka zvakadai, zvakashata-post-cataract chirwere magirazi. Varwere vaifara kuva necataract yakabviswa, asi kwete kufara kwazvo zvokuti vaifanira kunge vava kupfeka magirazi, akaremara.
Ndiani akasika phacoemulsification nzira?
Dr Charles D. Kelman, chiremba wehuputi, uye chiremba wechiremba muNew York, anorumbidzwa nekuvandudza kutanga kokutanga phacoemulsification process. pakunopera kwema1960 uye muna 1970 nzira yacho yakawanikwa kune vanovhiya. Dr. Kelman akashanda pamagariro akasiyana-siyana uye maitiro asi akawana pfungwa ye phacoemulsification mushure mekugara pachigaro chemazino achiita mazino ake akacheneswa ne-high-speed ultrasonic cleaner.
Zvinonakidza, zvimwe zvepfungwa dzepakutanga dzaaiva nadzo dziri kuratidza zvakare muzuva ranhasi chirwere chechipatara.
