Muraayadaha wax akhrisku waa nooc ka mid ah muraayadaha indhaha, kuwaas oo bixiya muraayadaha myopia ee ay caadi ahaan isticmaalaan dadka qaba presbyopia, kuwaas oo ka tirsan lens-ka convex.Muraayadaha wax akhriska ayaa loo isticmaalaa in lagu buuxiyo aragga dadka da'da dhexe iyo kuwa da'da ah.Sida muraayadaha myopia, waxay leeyihiin qiimeyaal elektaroonig ah oo indhaha ah oo badan oo looga baahan yahay heerarka warshadaha qaranka, waxayna sidoo kale leeyihiin codsiyo gaar ah oo joogto ah.Sidaa darteed, muraayadaha akhriska waa in lagu qalabeeyaa muraayado.
Marka hore, kala soocida aasaasiga ah ee muraayadaha akhriska
Waqtigan xaadirka ah, waxaa jira saddex nooc oo ah muraayadaha wax akhriska ee suuqa, kuwaas oo kala ah lens-ka-aragga, muraayadaha bifocal iyo lens multifocal asymptotic.
Lens-arag keliya ayaa loo isticmaali karaa in lagu arko meel dhow, waana in aragga dib loo soo celiyaa marka la eego fogaanta.Waxay ku habboon tahay oo keliya dadka qaba presbyopia fudud iyo inta jeer ee hooseeya ee isticmaalka muraayadaha akhriska;
Bifocals waxay tixraacaan muraayadaha wax lagu akhriyo ee leh muraayadda muraayadda sare ee loo isticmaalo in lagu arko meel fog, iyo muraayadda muraayadda badhkeed ee hoose ayaa loo isticmaali jiray in lagu arko meel u dhow, laakiin muraayadaha akhriska ee noocan oo kale ah waxay yeelan doonaan indho-beel iyo boog, xirashada muddada dheer waxay aad ugu nugul tahay xanuunka indhaha, dawakhaad. iwm, nashqadeynta guduhu ma fiicna, mana aha hadda mid caadi ah;muraayada indhaha ee asymptotic multifocal waxay buuxin kartaa shuruudaha aragga cakiran ee masaafo kala duwan masaafada, dhexe iyo dhowba.Muuqaalku waa tignoolajiyada sare iyo moodada, waxayna aad ugu habboon tahay myopia casriga ah ee ka weyn da'da 40. Eye plus presbyopia, astigmatism group wear.
Marka labaad, xaaladaha codsiga ee muraayadaha akhriska
Presbyopia waa dhacdo caadi ah oo jireed, ma aha cudur indhaha ah, mana aha kaliya qof da' ah.Ka dib da'da 40, iyada oo si tartiib tartiib ah loo adkeynayo fiilooyinka kiimikada ee lenska indhaha iyo kabuubyada tartiib-tartiibka ah ee jidhka ciliary, isha bini'aadamku si macquul ah uma hagaajin karto muuqaalka muuqaalka (radial transformation).Iyada oo ku xidhan masaafada u dhaxaysa shayada, waa in aad ka fogaataa marka aad eegayso walxaha dhow ka hor inta aanad si fiican wax u arkin.Xaalada labada indhood wakhtigan waxa loo yaqaan presbyopia.
Haddii presbyopia ay rabto inay isticmaasho aragga indhaha ee fogaanta caadiga ah ee asalka ah, waa lagama maarmaan in la xidho muraayadaha wax lagu akhriyo si loo buuxiyo aragga indhaha, si aragtida dhow si cad dib loogu arko.Laba indhood oo indho.Heerka myopia ee presbyopia waxay la xiriirtaa da'da.Marka ay korodho da'da, xumaanta muraayadda indhaha ayaa kordhi doonta, heerka myopia ayaa si tartiib tartiib ah u kordhi doona.
Horay ayey u dhacday Presbyopia, haddii aad ku adkaysato in aanad xidhin muraayadaha wax akhriska, jidhku wuu daalan doonaa oo la qabsan kari la’a, taas oo hubaal ah in ay dhibka akhriska uga sii dari doonto, dawakhaad, dawakhaad iyo cuduro kale oo badan, kuwaas oo khatar gelinaya nolol maalmeedka iyo shaqada.Kalsooni sare.Sidaa darteed, muraayadaha presbyopia waa in isla markiiba la isku dhejiyaa iyada oo aan dib loo dhigin (dadka Shiinuhu waxay leeyihiin fikrad khaldan: waxay u maleynayaan in xirashada muraayadaha akhriska ay tahay "cudur" halis ah, mana aqoonsanayaan jiritaanka muraayadaha akhriska. Tani waa fikrad khaldan) .
Ka dib markii uu weynaado, muraayadaha akhriska ee asal ahaan ku qalabaysan myopia aan ku filnayn waa in isla markiiba la beddelaa.Sidaa darteed, muraayadaha akhriska waa in aan la gashan mar kasta.Xidhashada muraayadaha akhriska ee muddada-dheer ee leh heerka aan habboonayn ee myopia kaliya ma keenayso dhibaato badan oo nolol maalmeedka qofka, laakiin sidoo kale waxay sii wadi doontaa dedejinta habka presbyopia binocular.
Xaaladaha caadiga ah, waxaa jira laba astaamood oo waaweyn oo presbyopia ah marxaladda hore:
Marka hore waa shaqo dhow ama akhris adag.Tusaale ahaan, marka aad wax akhrinayso, waa in aad buugga ka fogaysaa, ama waa in aad ku akhridaa meel ilo iftiin xooggan leh si aad u aqoonsato.
Midda labaad waa daalka indhaha.Marka la dhimo awoodda hoyga, shuruudaha akhrisku waxay si tartiib tartiib ah u soo dhowaanayaan xadka awoodda hoyga, taas oo ah, marka la akhrinayo, asal ahaan dhammaan awoodda hoy ee labada indhood waa in la isticmaalo, si aanay suurtogal u ahayn in la isticmaalo indhaha muddo dheer, iyo Aad bay u fududahay in ay sababto bararka isha sababtoo ah laqabsiga xad dhaafka ah.madax-xanuun iyo calaamado kale oo daalka aragga ah.
Dhacdooyinka labada xaaladood ee kor ku xusan waxay muujinayaan in indhuhu ay u badan tahay inay si tartiib tartiib ah u duqoobaan.Kooxaha miyir-qabka, waxa lagama maarmaan ah in ay iska bixiyaan muraayadaha indhaha ama buug-akhrinta meel fog marka la akhrinayo meel u dhow, taas oo sidoo kale ah muujinta ugu weyn ee presbyopia.Ka dib marka labada indhood ay yihiin presbyopic, habka ugu badbaado badan waa in la xidho muraayadaha wax-akhriska ee ku habboon hagaajinta.
