Iyadoo horumarinta keratoconus ee marxaladda hore, waxaa suurtagal ah in lagu saxo dhibaatooyinka aragga ee muraayadaha caadiga ah. Laakiin taariikhda dambe, xulashada lenses gaar ah, keratoconus waa lagama maarmaan.
Keratoconus waxay ku dhacdaa natiijada habka dystrophic ee xudunta, taas oo keenta khafiifinta, samaynta soo-baxa qaab-dhismeedka koontada. Inkasta oo cudurka pathology laftiisa la sheegay muddo dheer, sababta dhabta ah ee koritaankeeda ilaa hadda lama xaqiijin, ka dib marka la ogaado cudurka, way adagtahay in la ogaado waxa koorsadu noqon doonto.
Muujintu waxay ku dhacdaa da'da da'da yar, badanaa 15-25 sano, korriintu waa suurtogal labadaba degdeg iyo gaabis labadaba, mararka qaarkood cudurku wuu baaba'aa si iskiis ah, laakiin xaaladaha qaarkood horumarku wuxuu ku dhacaa qallafsanaanta cornea.
Waxaa ka mid ah cabashooyinka muhiimka ah, waxaa jiri kara aragti labanlaab ah, calaamadaha myopia, taas oo noqota sababta xulashada muraayadaha ama muraayadaha, laakiin waxay ku caawiyaan wakhti gaaban waxayna muujinayaan sababta dhabta ah ee pathology ee dusha sare ee cornea.
Asal ahaan, oo leh keratoconus, myopia ama astigmatism ayaa dhacda, taas oo la xiriirta isbeddelka qalooca ee cornea, laakiin muraayadaha caadiga ah ama muraayadaha ayaa noqda "yar" wax ka yar hal sano sababtoo ah horumarinta cilladaha indhaha.
Ma xiran karaa lenses leh keratoconus?
Waxaa muhiim ah in la xoojiyo in isticmaalka muraayadaha ama muraayadaha ee horumarinta keratoconus aysan ku caawinaynin daaweynta pathology. Alaabta indhaha ayaa kaliya ka caawiya inay magdhabaan cilladaha muuqaalka jira, laakiin cudurka laftiisa ayaa sii wadi kara horumarkiisa.
Muraayadaha loogu talagalay hagaajinta cudurrada muuqaalka ee ka soo horjeeda asalka keratoconus ayaa si dhif ah loo isticmaalaa, si buuxda uma baabi'in karaan aberrations. Muraayadaha indhaha ayaa si fiican ugu habboon dusha sare ee cornea, sidaas darteedna waxay caawiyaan ciribtirka khalkhalka aragga.
Muraayadaha nooca keratoconus waa kuwee?
Muraayadaha caadiga ah ee jilicsan ayaa kaliya loo isticmaali karaa marxaladda hore ee pathology, haddii isbeddelada dib-u-celinta ay yihiin ilaa 2,5 diopters. Ka dib, aragti cad ayaa lagu gaari karaa iyadoo la adeegsanayo lenska naqshadaynta toric. Intaa waxaa dheer, waa lagama maarmaan in la doorto moodooyinka leh walxaha silico-hydrogel, sababtoo ah gaaskooda sare ee gaaska.
Marxaladda dambe ee cudurka, lenses keratoconus gaar ah ayaa loo isticmaalaa, waxaa loo sameeyaa oo kaliya si loo dalbado iyadoo loo eegayo cabbirka shakhsi ahaaneed ee cornea. Waxay noqon karaan mid jilicsan ama adag ama isku-dhafan.
Waa maxay faraqa u dhexeeya muraayadaha keratoconus iyo muraayadaha caadiga ah?
Doorashada muraayadaha indhaha ee bukaanada qaba keratoconus waa in kaliya uu qabtaa dhakhtarka indhaha. Waxaa loo samayn doonaa si gaar ah, iyadoo loo eegayo xajmiga cornea. Haddii kuwani yihiin alaab jilicsan oo si gaar ah loo sameeyo, waxay u qaybsan yihiin laba kooxood:
- axisymmetric, oo leh dhumuc weyn oo dhexda ah - muraayadahani waxay sixi karaan myopia, laakiin ma awoodaan inay baabi'iyaan astigmatism, waxay ku habboon yihiin kaliya keratoconus, kaas oo cornea uu ka dhaawac yar yahay bartamaha marka loo eego hareeraha;
- lenses toric ayaa kaa caawin doona astigmatism, gaar ahaan heerkeeda sare.
Haddii kuwani yihiin lenses adag, sidoo kale waxaa loo qaybiyaa cabbir ahaan waxaana loo qaybiyaa laba kooxood:
- oo leh dhexroor yar (illaa 10 mm), corneal - inta badan dhowr lammaane oo lenses ah oo naqshado kala duwan ayaa la sameeyaa si loo dalbado, iyaga oo dooranaya raaxada ugu badan ee xirashada.
- oo leh cabbir weyn (laga bilaabo 13,5 mm ama ka badan), corneoscleral ama scleral, alaabta gaaska-permeable, marka la gashado, ku nasato sclera iyada oo aan taaban aagga uXNUMXbuXNUMXbthe keratoconus laftiisa - waxay ku raaxaystaan, laakiin aad u adag. in la doorto.
Alaabta isku-dhafan waa isku-darka labadii kooxood ee hore. Qaybtooda dhexe waxay ka samaysan tahay walxo oksijiin ah oo la dhaafi karo, laakiin dhinaca kale waxay yihiin kuwo jilicsan, oo ka samaysan silikoon hydrogel. Muraayadahani waa kuwo raaxo leh, oo si fiican loogu dhejiyay cornea, waxay bixiyaan hagaajinta aragti tayo sare leh, laakiin lama isticmaali karo marka cornea qalalan yahay.
Reviews dhakhaatiirta ku saabsan lenses for keratoconus
"Marka la eego astigmatism ba'an ee la socota keratoconus, sida caadiga ah, hagaajinta xiriirku waxay noqotaa ikhtiyaarka lagu gaaro aragtida ugu fiican," ayuu yidhi. dhakhtarka indhaha Maxim Kolomeytsev. -Waqtiga iyo inta jeer ee beddelka lensku aad bay u kala duwanaan karaan iyadoo ku xidhan nooca muraayadda la doortay (leensiska jilicsan ama muraayadaha gaaska adag ee lenses) iyo heerka horumarka cudurka.
