Iyada oo kor u kaca cudurka myopia adduunka oo dhan sannadihii u dambeeyay, ma jirto yaraan bukaanno u baahan in la daweeyo.Qiyaasta baahsanaanta Myopia iyadoo la adeegsanayo Tirakoobka Mareykanka ee 2020 ayaa muujinaya in waddanku u baahan yahay 39,025,416 baaritaanno indhaha ilmo kasta oo qaba cudurka 'myopia' sannad kasta, iyadoo laba imtixaan sannadkii.mid
Qiyaastii 70,000 ee dhakhaatiirta indhaha iyo dhakhaatiirta indhaha ee waddanka oo dhan, khabiir kasta oo daryeelka indhaha ah (ECP) waa inuu xaadiraa 278 carruur ah lixdii biloodba mar si uu u buuxiyo shuruudaha daryeelka indhaha ee hadda jira carruurta qaba myopia ee Maraykanka.1 Taasi waa celcelis ahaan in ka badan 1 myopia caruurnimo oo la baaro lana maareeyo maalintii.Sidee buu dhaqankaagu uga duwan yahay?
ECP ahaan, yoolkeenu waa in aan dhimno culayska myopia ee sii socota oo aan ka caawino ka-hortagga indho la'aanta muddada dheer ee dhammaan bukaannada qaba myopia.Laakiin maxay bukaankeenu ka fikiraan sixiddooda iyo natiijooyinkooda?
Marka ay timaaddo orthokeratology (Orthokeratology), jawaab celinta bukaan-socodka ee tayada nololeed ee la xidhiidha aragga waa qaylo.
Daraasad ay samaysay Lipson et al., Iyada oo la adeegsanayo Machadka Qaranka ee Cudurrada Indhaha oo leh Qalad Refractive Quality of Life Questionnaire, marka la barbar dhigo dadka waaweyn ee xiran muraayadaha indhaha ee jilicsan ee hal aragga leh dadka waaweyn ee xiran lenses orthokeratology.Waxay ku soo gabagabeeyeen in guud ahaan qanacsanaanta iyo aragga la barbardhigo, si kastaba ha ahaatee qiyaastii 68% kaqeybgalayaashu waxay door bideen Ortho-k waxayna doorteen inay sii wadaan isticmaalka dhamaadka daraasadda.2 Mawduucyada ayaa soo sheegay doorbidida aragga aan saxda ahayn ee maalintii.
Halka dadka waaweyni ay doorbidi karaan Ortho-k, ka waran aragga dhow ee carruurta?Zhao iyo al.la qiimeeyay carruurta ka hor iyo ka dib 3 bilood ee xidhashada orthodontic.
Carruurta isticmaala Ortho-k waxay muujiyeen tayada sare ee nolosha iyo faa'iidooyinka hawl maalmeedkooda, waxay u badan tahay inay tijaabiyaan waxyaabo cusub, waxay ahaayeen kuwo isku kalsoon, firfircooni badan, iyo inay u badan tahay inay ciyaaraan ciyaaraha, taas oo ugu dambeyntii keentay waqti badan oo lagu bixiyo. daaweynta.wadada.3
Waxaa suurtogal ah in habka guud ee daaweynta myopia ay gacan ka geysan karto in la sii wado la shaqeynta bukaanada oo si ku filan u caawiyo maareynta ku-dhaqanka muddada dheer ee habka daaweynta ee looga baahan yahay daaweynta myopia.
Ortho-k waxay horumar la taaban karo ka samaysay muraayadaha iyo naqshadaynta alaabta tan iyo markii ugu horeysay ee FDA oggolaatay ee muraayadaha indhaha ee ortho-k ee 2002. Laba mawduuc ayaa maanta ka soo muuqday dhaq-dhaqaaqa kiliinikada: muraayadaha Ortho-k oo leh farqi qoto dheer oo dhexdhexaad ah iyo awoodda lagu hagaajinayo dhexroorka aagga aragga dambe.
Iyadoo lenses meridian orthokeratology sida caadiga ah loo qoro bukaanada qaba myopia iyo astigmatism, fursadaha lagu rakibo iyaga ayaa aad uga badan kuwa lagu saxayo myopia iyo astigmatism.
Tusaale ahaan, iyada oo la raacayo talooyinka soo-saaraha, si macquul ah loogu talagalay bukaanada leh toricity xudunta xudunta 0.50 diopters (D), farqi qoto dheer oo aagga soo celinta ayaa si macquul ah loo qoondayn karaa.
Si kastaba ha ahaatee, qadar yar oo lens toric ah oo ku yaal cornea, oo ay weheliso lenska Ortho-k kaas oo tixgelinaya farqiga qoto dheer ee meridional, ayaa hubin doona dheecaanka jeexjeexa ee saxda ah iyo udubdhexaadinta ugu fiican ee muraayadda hoosteeda.Sidaa darteed, bukaannada qaar ayaa laga yaabaa inay ka faa'iidaystaan ​​xasilloonida iyo ku habboonaanta ugu fiican ee ay bixiso naqshaddan.
Tijaabo caafimaad oo dhowaan la qaaday, muraayadaha lafaha 5 mm dhexroorka aagga aragga dambe (BOZD) waxay faa'iidooyin badan u keeneen bukaannada qaba myopia.Natiijooyinku waxay muujiyeen in 5 mm VOZD ay kordhisay hagaajinta myopia by 0.43 diopters ee booqashada 1-maalin marka la barbar dhigo 6 mm VOZD design (lens control), bixinta sixitaan degdeg ah iyo hagaajinta muuqaalka muuqaalka (Jaantus 1 iyo 2).4,5
Jung iyo al.Waxa kale oo la ogaaday in isticmaalka 5 mm BOZD lenska Ortho-k ay ​​keentay hoos u dhac weyn oo ku yimid dhexroorka aagga daaweynta topographic.Markaa, ECP-yada hiigsanaya inay gaadhaan qiyaaso daawaynta oo ka yar bukaankooda, 5 mm BOZD waxay caddaysay inay faa'iido leedahay.
In kasta oo ECP-yo badan ay yaqaaniin ku habboonaanta muraayadaha indhaha ee bukaanka, ha ahaado mid ogaanshaha ama si macquul ah, hadda waxaa jira habab cusub oo lagu kordhinayo gelitaanka oo loo fududeeyo habka habboonaanta bukaan-socodka.
La bilaabay Oktoobar 2021, Paragon CRT Calculator app (Jaantuska 3) wuxuu u oggolaanayaa dhakhaatiirta xaaladaha degdegga ah inay qeexaan cabbirrada bukaannada qaba Paragon CRT iyo CRT Biaxial (CooperVision Professional Eye Care) nidaamyada orthokeratology oo ay ku soo dejiyaan dhowr dhagsi.DalboTilmaamaha cilad-raadinta gelitaanka degdega ah waxay bixiyaan qalab caafimaad oo faa'iido leh wakhti kasta, meel kasta.
2022, baahsanaanta myopia shaki la'aan wuu kordhi doonaa.Si kastaba ha ahaatee, xirfadda indho-indheynta ayaa leh ikhtiyaaro daaweyn oo horumarsan iyo qalab iyo agab si ay gacan uga geystaan ​​isbeddelka nolosha bukaannada carruurta ee qaba myopia.
