Iilensi zamnyama zokubuyiselwa kombono

I-Orthokeratology - indlela yokubuyisela umbono, okubandakanya ukugqoka ii-lens ebusuku. Le yindlela yokulungiswa kokungagqirha. Kuze kube yimini, kuthathwa njengenye yeyona ndlela iphumelelayo kwaye ilula, ngoko inani elinyukayo yezigulane ze-ophthalmology liye lisebenzisa uncedo lwayo.

Ziziphi iilensi zomlingo wombono?

Ngundoqo, iilensi eziqhelekileyo zobusuku azifani kakhulu. Uhlobo oluphambili kukuba zenziwe ngezinto ezinqabileyo zogesi. Ngethuba le-OC unyango, umphumo kwi-cornea kunye noshintsho oluthileyo lwenziwa kancane kancane.

Ubusuku bobusuku bokuqala babonakala kwiminyaka engama-60. Kakade ke, ukususela ngoko ngoko ukuyila kwabo kuguqukile kakhulu kwaye kuphuculwe. Umgaqo wokusebenza kwabo usekelwe kwinto yokuba, kunye ne-myopia, imibala yokukhanya, ngokugqithisela imidiya ebonakalayo yamehlo, ijoliswe ngqo phambi kwe-retina. Ukugxininisa kwi-retina, kufuneka uguqule umlo we-cornea-ukwenza kube yincinane. Ukwenza oku, udinga iilensi ezinzima ukubuyisela umbono. Bancedisa ukudala uhla olutsha "olungileyo" lomphezulu we-cornea.

Esinye seziganeko ezibalaseleyo zendlela yukuthi emini, isiguli asiyidingi naluphi na optics yokulungisa. Kodwa ukuba imigaqo ye-orthokeratological isebenze, iilensi zebusuku mazibe zigugile rhoqo okanye ubuncinane ubusuku. Ukuba uwashiya ngaphambi kwexesha, emva kweentsuku ezintathu i-cornea iya kubuya kwimeko yokuqala.

Impembelelo yokusebenzisa unyango lwe-refractive - ukulungiswa kombono ebusuku kunye neelensi zelanga

Ngokwezibalo, i-orthokeratological lenses inokulungisa i-myopia kwi--1.5 ukuya kwi-4 diopters. Kwakukho iimeko xa le ndlela ikuncede izigulane nge- myopia kwi-di-5 ne -6 diopters. Kodwa kude kube ngoku aqhelekanga.

Izinguqu eziphezulu zijongwa ngokukhawuleza emva kokuqala kwesicelo seelensi. Kule ngongoma, ukulungiswa kwe-75% yombono kwenzeka. Kodwa ukubuyiselwa ngokupheleleyo kuza kwenzeka emva kobusuku obunama-7 no-10. Ngethuba lokunyanga emini, xa isigulane singekho kwiilensi, umphumo ungancipha. Oku kuqhelekileyo.

Izinzuzo zamalensi ezigqoke ubusuku ukubuyisela umbono:

1. Ukungafani. Abanalo mingcipheko yobudala. Kwaye oku kuthetha ukuba bangasetyenziswa ngabantwana abangafanelekanga ukulungiswa kwelasi.
2. Khu seleko. Ngaphantsi kwee-lens ezilungekileyo, i-cornea ayiveki ukungabikho kwe-oksijeni, njengokuba kwenzeka kwimeko yomini. Kwaye kunye ne-hypoxia yasebusuku, ekhulayo phantsi kweelusiki ezivaliweyo, ihlawulwa ngokupheleleyo ngemini.
3. Hypoallergenicity. I-lorkeratological lenses ayibangeli ukubandezeleka, i-conjunctivitis, i- keratitis . Ukongeza, banokusebenzisa ngokuphepha nayiphi na indlela yokwenza. Into ephambili yokuyihlamba ebusuku.
4. Elide. Iilensi zamnyama zokubuyisela umbono zinexesha elide lokuphila. Kwaye ngokunyamekela, abayi kuguqulwa.

Kananjalo okunye: ezi iilensi azikho ukulinganiselwa kobugcisa, akufanele zisuswe rhoqo ngexesha lemidlalo okanye ukubhukuda. Bafanelekile nakwabo bantu abaziva bengakhululekile kwii-lens eziqhelekileyo.

Ukungqinelana nokusetyenziswa kweelensi zamnyama ukubuyisela umbono

Ngeendlela ezichasayo kubalulekile ukuba zifikeleleke, kodwa zi:

1. I-lorkeratological lenses ayikwazi ukugqithwa kwizigulane ezinezifo ezivuthayo emehlweni nakwiinkophe.
2. Le ndlela inokulimaza abo banezikrakra kwinqanaba eliphambili le-cornea.
3. Kuyinto engathandekiyo ukusebenzisa iilensi kwi-syndrome eyomeleleyo yamehlo.
4. Ngexesha lokugula, elihamba nefiva kunye neempumlo ze-runny, ukugqoka iilensi kufuneka kupheliswe.
