Keratoconus inosanganisira iyo inokonzera cornea, iyo yakajeka dome-yakaita sarudzo pamucheto uri mberi kweziso rako. Zvishoma nezvishoma uye zvishoma nezvishoma, the cornea inotanga kubuda kunze uye kuwedzera.
Ne keratoconus, iwe unowedzera kuonekwa uye unogona kukura huru uye zvisingaverengeki zveastigmatism. Sezvo mararamiro ako achifambira mberi, iyo cornea inogona kukura masaga.
Mune zvimwe zviitiko, kuwedzera kwekorome kunogona kuva kwakakosha zvokuti inogona kuonekwa pachena pasina microscope.
Chiratidzo Kururamiswa
Sezvo keratoconus ichifambira mberi, unogona kutanga kunzwa zvakasvibiswa kana kuti kukanganisa maonero ayo akaoma kururamisa nemakirasi emaziso. Kana izvi zvikaitika, fungidziro dzemagetsi dzinowanzokurudzirwa nechiremba weziso rako. Kana ikorome yako yakanyanganisa zvakanyanya, gasi yakaoma inogadziriswa lenzi kana mavarai anonyatsogadzikana anowirirana anokurudzirwa. Aya majekisi anowanzopedza zvachose cornea, uye pamwe chete neanonzi inonzi lens lens (misodzi inozadza pasi pe lens), mask asingagadziri astigmatism , kukurumidza kana kupotoka. Kunyange zvazvo nzira iyi inoshanda zvakanaka muzviitiko zvakawanda, vamwe vanhu vanotambura nekeratoconus vanobatana-lens kusinganzwisisiki, zvichida nekuda kwemaziso akaoma kana kuti kubva pakusagadzikana kunosangana nekudzivirira kana kupora kwekonoa.
Mune vamwe vanhu vane keratoconus, iyo cornea inowedzera zvokuti zvakaoma kuwana gasi rakaoma gasi rinokonzerwa nemhepo inobuda kubva pameso avo.
Vanhu ava vanokanganiswa uye vanonzwa vakashungurudzika. Nokuti magirasi emaziso haakwanisi kugadzirisa dambudziko ravo rekuona, uye ikozvino kuonana kwemajeri kwemajeri hazvisi nyore, zvinotungamirira hupenyu hunofanirwa kubhadhara pakuonekwa kwavo kuderera. Apo lens zvingasarudzwa zvakapera, varwere ve keratoconus dzimwe nguva vanosiyiwa nesarudzo yekurapa iyo inosanganisira kuvhiyiwa uye zvichida inogadziriswa.
Soft Contacts
Munguva pfupi yapfuura, mutsva wekutengesa lens nyaya yakatsvaga yakagadzirirwa iyo inogona kubatsira vanhu vanove vasina kukanganisa zvetsika dzekugadzira lens. Zvitsva zviviri zvitsva zvitsva zvakatangwa: NovaKone (Alden Optical) uye Kerasoft IC (Bausch & Lomb).
- NovaKone: NovaKone lens, yakatangwa muna 2011, inopa mashizha mashanu anobatsira mask coral kupoteredza uye zvisina kukodzera astigmatism. Chii chinoita kuti izvi zvive zvakasiyana uye zvakabudirira zvemaoticometric kuti zvikwanise ndezvokuti kumushure kwemashure kwemajeri kune chevheji yakasiyana pane iyo inowanikwa. Iyo yakakomberedzwa yakakomberedzwa uye inoputika mavhirivheni inogona kuchinjwa zvisingatauriki kune mumwe kune imwe kuti igadzirise kukodzera kwe lens, uye lenzi inogona kuchinjwa zvakasiyana kune mumwe. Munguva yakapfuura, mazhenzi akareruka ainyanya kuumba mamiriro umo iyo cornea haina kuwana okwana yakakwana ku cornea uye yakagadzira nzvimbo isina kunaka yeziso. NeNovaKone lens, kushandiswa kwemisodzi pasi pe lens kunopa oksijeni yakanaka inoyerera. Kamwe murwere nemurume wake ari kugutsikana nekunyaradzwa uye maonero, lenzi inorayirwa mune imwe phuku kuitira kuti rimwe lens rinotsiviwa kwemwedzi mitatu.
- Kerasoft IC: Kerasoft IC lens, yakatangwa muna 2012, inogadzirwa nemashoko anonzi Definitive ane mvura yakadzika yehuwandu ye 74 muzana uye inosanganisira silicone iyo inobvumira kuti oksijeni yakanyanya kuyerera ichienda kune cornea. Somugumisiro, kuwanda kwema-lens hakuiti mamiriro ezvinhu akaipa ekunyanyisa kwehupenyu kweziso. Kungofanana neNovaKone lens, Kerasoft IC ine nheyo yepakati uye imwe yeropa inogona kuchinjwa zvakasununguka. Uyezve, mushandi anokwanisa kuchinja dzimwe nhengo dzemakona ekutsvaga kuti zvivandudzire nzira iyo lenzi inofanirana nayo paziso. I-lens yokutanga yakasarudzwa neanticometrist inotarisana nekorome shape uye rudzi rwe keratoconus, pane kungova kupera kwekonoa. Kungofanana neNovaKone lens, lens iyi inowanikwawo muine pfumbamwe-kushandiswa mana-pack pameso.
Zvaunofanira Kuziva
Kunyange zvazvo lenzi dzakanyorova dzave dzichishandiswa munguva yakapfuura kune varwere ve keratoconus, kukanganisa mune zvose zvakakodzera, zvakanakisisa-kuratidzwa maonero, kana kuti zuva nezuva kupfeka nguva kwaifanira kuitwa. Nekuuya kweizvi lensiti itsva, varwere ve keratoconus iye zvino vane imwe, zvichida yakanyanya kusununguka sarudzo yekugadzirisa matambudziko avo ekuonekwa ane keratoconus.
