Zamkatimu
Ndi chitukuko cha keratoconus mu gawo loyamba, ndizotheka kukonza mavuto a masomphenya ndi magalasi wamba. Koma m'tsogolomu, kusankha magalasi enieni a keratoconus ndikofunikira.
Keratoconus imachitika chifukwa cha njira ya dystrophic mu cornea, yomwe imatsogolera pakupatulira kwake, kupanga mawonekedwe owoneka ngati chulu. Ngakhale kuti matendawo adafotokozedwa kwa nthawi yayitali, chifukwa chenicheni cha chitukuko chake sichinakhazikitsidwe mpaka pano, ndipo pambuyo pozindikira matendawa, zimakhala zovuta kudziwa zomwe maphunzirowo adzakhala.
Ziwonetsero zimachitika ali aang'ono, nthawi zambiri pazaka 15-25, chitukuko chimatheka mofulumira komanso pang'onopang'ono, nthawi zina matendawa amatha okha, koma nthawi zina kupitirira kumachitika ndi mapindikidwe a cornea.
Pakati pa madandaulo ofunikira, pakhoza kukhala masomphenya awiri, zizindikiro za myopia, zomwe zimakhala chifukwa cha kusankha magalasi kapena magalasi, koma zimathandiza kwa nthawi yochepa ndikuwulula chifukwa chenicheni cha matenda mu mawonekedwe a cornea.
Kwenikweni, ndi keratoconus, myopia kapena astigmatism imapezeka, yomwe imagwirizanitsidwa ndi kusintha kwa kupindika kwa cornea, koma magalasi okhazikika kapena magalasi amakhala "aang'ono" pasanathe chaka chimodzi chifukwa cha kupitirira kwa zovuta za kuwala.
Kodi ndingavale magalasi ndi keratoconus?
Ndikofunika kutsindika kuti kugwiritsa ntchito magalasi kapena magalasi pakukula kwa keratoconus sikuthandiza pochiza matenda. Zopangira zowoneka bwino zimangothandizira kubweza zolakwika zomwe zilipo kale, koma matendawa amatha kupitilizabe.
Magalasi owongolera ma pathologies owoneka motsutsana ndi maziko a keratoconus sagwiritsidwa ntchito kawirikawiri, sangathe kuthetseratu zosokoneza. Magalasi olumikizana amakwanira bwino pamwamba pa cornea, motero amathandizira kuthetsa kusokonezeka kwamaso.
Ndi magalasi ati omwe ali abwino kwambiri kwa keratoconus?
Magalasi ofewa atha kugwiritsidwa ntchito poyambira matenda, ngati kusintha kwa refractive kukufika pa 2,5 diopters. Pambuyo pake, masomphenya omveka bwino amatha kupezedwa pogwiritsa ntchito lens yopangira toric. Komanso, m'pofunika kusankha zitsanzo ndi silico-hydrogel zinthu, chifukwa mpweya permeability awo mkulu.
Kumapeto kwa matendawa, magalasi apadera a keratoconus amagwiritsidwa ntchito, amapangidwa kuti azingoyitanitsa malinga ndi kukula kwake kwa cornea. Zitha kukhala zofewa kapena zolimba kapena zosakanizidwa.
Kodi pali kusiyana kotani pakati pa magalasi a keratoconus ndi ma lens wamba?
Kusankhidwa kwa magalasi kwa odwala omwe ali ndi keratoconus kuyenera kuchitidwa ndi ophthalmologist. Adzapangidwa payekhapayekha, malinga ndi kukula kwa cornea. Ngati izi ndi zinthu zofewa zomwe zimachitidwa payekha, zimagawidwa m'magulu awiri:
- axisymmetric, kukhala ndi makulidwe pakati - magalasi awa amatha kukonza myopia, koma sangathe kuthetsa astigmatism, ndi oyenera keratoconus, momwe cornea imawonongeka pang'ono pakati kusiyana ndi periphery;
- magalasi a toric amathandizira ndi astigmatism, makamaka ndi digiri yake yayikulu.
Ngati awa ndi ma lens olimba, amagawidwanso ndi kukula ndikugawidwa m'magulu awiri:
- ndi mainchesi ang'onoang'ono (mpaka 10 mm), cornea - nthawi zambiri magalasi angapo amitundu yosiyanasiyana amapangidwa kuti ayitanitsa, kuwasankha kuti azitha kuvala bwino.
- zokhala ndi kukula kwakukulu (kuyambira 13,5 mm kapena kupitilira apo), corneoscleral kapena scleral, zopangidwa ndi mpweya zomwe, zikavala, zimapumira pa sclera osakhudza dera la uXNUMXbuXNUMXbkeratoconus palokha - zimakhala zomasuka, koma zovuta kwambiri. kusankha.
Zopangira zophatikiza ndi kuphatikiza kwa magulu awiri am'mbuyomu. Mbali yawo yapakati imapangidwa ndi zinthu zomwe zimatha kutulutsa mpweya, koma m'mphepete mwake ndi ofewa, opangidwa ndi silicone hydrogel. Magalasi awa ndi omasuka, okhazikika pa cornea, amapereka kuwongolera masomphenya apamwamba, koma sangagwiritsidwe ntchito pamene cornea youma.
Ndemanga za madokotala za magalasi a keratoconus
"Poganizira za astigmatism yoopsa yomwe imatsagana ndi keratoconus, monga lamulo, kuwongolera kulumikizana kumakhala njira yopezera mawonekedwe abwino kwambiri," akutero. ophthalmologist Maxim Kolomeytsev. - Nthawi ndi kuchuluka kwa ma lens m'malo mwake kumatha kusiyanasiyana kutengera mtundu wa magalasi osankhidwa (magalasi ofewa kapena magalasi owoneka bwino a gasi) komanso kuchuluka kwa matendawa.
Mafunso ndi mayankho otchuka
Tinayankhula ndi ophthalmologist Maxim Kolomeytsev za vuto la keratoconus ndi kukonza mandala mmenemo, anafotokozera ena mwa nuances mankhwala.
