DMuraayadaha efocus Incorporated Multiple Segments Muraayadaha waxaa loogu magac daray sababtoo ah waxaa jira tiro muraayado yaryar oo indhaha qaawan laga arki karo xaglo gaar ah oo ku yaal dusha sare ee muraayadda, kuwaas oo ku kala firirsan qaab dhibic ah, sidaas darteed magaca. Muraayadaha Defocus Incorporated Multiple Segments waa nooc ka mid ah muraayadaha ka hortagga myopia iyo xakamaynta, kuwaas oo ka kooban laba meelood. Mid waa aagga dhexe ee indhaha loo isticmaalo si loo saxo khaladaadka refractive (myopia, fogarsightness iyo astigmatism), kan kalena waa bartamaha oo ku fidsan hareeraha muraayadda. Aagagga defocus myopic ee aag badan. Marka qofka xiran uu eego walxaha masaafooyin kala duwan, muraayadaha defocus ee qaybo badan leh waxay bixin karaan aragti cad iyo myopia defocus isku mar, waxayna ka hortagi karaan oo xakamayn karaan koritaanka myopia iyadoo la saxayo aragtida.
Mabda'u waa in la isticmaalo habka jawaab celinta dabiiciga ah ee isha - ifafaalaha emmetropization, si aragtida, horumarka muuqaalka iyo sawirka isha ee isha ay ugu dhow yihiin saameynta muuqaalka ee isha emmetropic.
Waqtigan xaadirka ah, myopia-ga dhabta ah ee dhalinyarada badanaa waa myopia-ga axial, kaas oo ay sababto koritaanka dhidibka isha. Sababtoo ah dheereynta kubbadda isha, booska sawirka waxaa lagu saadaaliyaa hortiisa retina. Marka la saxayo muraayadaha myopia-ga caadiga ah, sixitaanka ugu cad waxaa loogu talagalay oo keliya aragtida dhexe, naqshadeynta muraayadda lafteeduna si tartiib tartiib ah ayay u kordheysaa ama si aan caadi ahayn ayay u kordhisaa heerka aagga ka baxsan iftiinka dhexe. Ka dib sixitaanka, isla shayga waxaa lagu saadaalin karaa fovea ee macula iyada oo aan wax dhibaato ah la kulmin, taasoo hubinaysa aragti cad. Si kastaba ha ahaatee, shayga ay heshay retina-da durugsan si toos ah uma taal retina, laakiin waxaa lagu sawiraa dhinaca dambe ee retina. Tani waxay sidoo kale horseedi doontaa waxa aan hadda u aragno hyperopia-ga oo aan diiradda saarin, kaas oo hadda loo aqoonsaday mid ka mid ah sababaha ugu waaweyn ee sameynta myopia iyo qoto dheeraanta cilmi-baarayaashu. Tani waa sababta oo ah hyperopia-ga oo ka baxaya dhinaca dambe ee retina wuxuu kiciyaa koritaanka dhidibka isha ee dhinaca dambe, taasoo horseedaysa korriin axial iyo qoto dheeraansho myopia ah.
Muraayadaha yaryar ee ku jira aagga furfurka indhaha waxaa si gaar ah loogu talagalay inay lahaadaan heer ka duwan muraayadda keli ah ee ku taal aagga saxitaanka, taasoo keenta in sawirku uu ku dhaco horteeda isha, taasoo keenta furfurka indhaha oo siiya calaamad u socota dhidibka indhaha, taasoo keenaysa saameynta dib u dhigista qoto dheeraanta indhaha.
Faa'iidada:
1. Saamaynta xakamaynta myopia waa mid iska cad: saameynta dib u dhigista ee koritaanka myopia waa mid aad u sarreysa ilaa 59%, saameynta xakamaynta ee koritaanka axial-kana waa mid aad u sarreysa ilaa 60%.
2. Ku habboonaan fudud: Muraayadaha indhaha ee 'myopia defocus' ee leh dhibco badan waa nooc gaar ah oo muraayad hal-focus ah, ku habboonaantuna waa mid fudud.
3. Raaxo sare: Muraayadaha indhaha ee aan lahayn indhaha oo leh dhibco badan ma laha meel astigmatism ah mana taabanayaan isha aadanaha. Si ka duwan muraayadaha indhaha ee la xiriira cornea, ma keenaan raaxo darro.
4. Daryeel fudud: Marka la barbar dhigo muraayadaha kale, sida muraayadaha orthokeratology, kuwaas oo u baahan dhaqidda gacmaha iyo jeermiska mar kasta oo la iska saaro oo la xidho, dayactirka muraayadahana wuxuu u baahan yahay xalal daryeel oo gaar ah.
5. Saamaynta dib u dhaca ee myopia waa mid aad u sarreysa ilaa 59%, saameynta xakamaynta ee koritaanka axial-kana waa mid aad u sarreysa ilaa 60%.
