Ama-lens axhumene ne-gas alingenekayo: ukubuyekezwa, ukukhiqizwa. Ukunakekela ama-lens okuxhumana okuqinile: i-cleaner yansuku zonke yama-lens asebenzayo kagesi ahambisanayo

Kuze kube manje, kunezindlela eziningi zokulungisa umbono. Ngokuvamile ukuthuthukisa ubukhali bayo, ukuqeda ezinye izinkinga, uxhumane namalensi asetshenziswa. Ngokuya ngohlobo lwezinto ezibonakalayo, hlukanisa phakathi kwe-lens okuthintana neyinkimbinkimbi yegesi yokuxhumana. Yiqiniso, uhlobo lokuqala luvame ukusetshenziselwa, kepha lo mlando unenzuzo eminingi.

Izinto zokukhiqiza zamalensi aqinile

Ama-lens amancane aqhuma kakhulu ngasekupheleni kwekhulu lama-20. Khona-ke ukwaziswa okuyinhloko kokukhiqizwa kwabo kwakuyi-polymethyl methacrylate. I-lens ngokwayo yayinobuncane obukhulu. Ukungalungi kwamalensi anjalo kwakungabikho kokushintshaniswa kwegesi. Ukufinyelela kwe-oksijeni kuya ku-cornea kwagcwaliseka kuphela ngenxa yokuhamba kanye nosayizi omncane wendlela yokulungisa lokho. Kodwa-ke, namuhla izinto ezisetshenzisiwe zanamuhla nezokufaneleka ziyasetshenziswa. Ama-lens axhumene ne-gesi angenamandla angenziwa ngama-compilation-silicone compounds. Ngenxa yalokhu, i-lens ine-oksijeni enhle yokubeka amandla. Kumele kuqashelwe ukuthi zikhululekile, zenziwa ngabanye, ziveza ukulungele ngqo kwesiguli esithile.

Izinkomba zokusetshenziswa kwamalensi aqinile

Amalensi othintana naye amancane anemikhawulo ebangeni lobukhulu bokukhanya. Ngokuvamile zichazwe i-myopia kuya ku -12 diopters, i-myopia ayikho ngaphezu kwe-diopters engu-8. I-myopia enamandla kakhulu idinga ukulungiswa okuqondile. Ama-lens amancane anezinhlawulo ezinkulu zamandla okukhanya azoba nobukhulu obukhulu kulokhu. Lokhu, kwandisa ingozi yezinkinga (ukulingana okuqinile kungaholela ku-eye hypoxia). Kodwa-ke, ungasebenzisa izibuko, kodwa namuhla ochwepheshe banikeza ama-lens asebenzayo kagesi aphephile. Zinezinhlobo ezihlukahlukene zokwehliswa - kusuka ku--25 diopters kuya ku-+25 amayunithi. Ukusetshenziswa kwezinto zanamuhla kuqinisekisa ukutholakala okwanele oksijini kweso. Kulesi simo, ukuqina kwamalensi anjalo akufani kakhulu nemingcele ehambelanayo yemikhiqizo ethambile yokulungisa umbono.

Ukwakhiwa kwe-lens eqinile

Ama-lens anzima anamuhla anendawo yokukhanya, ephakathi nendawo yomkhiqizo. Ububanzi balo abudluli 8 mm. Ngenxa yendawo yokudonsa, enesakhiwo esithile, i-lens isilondolozwe ngokuqinile e-eyeball. Indawo enqenqemeni inezilinganiso ezincane kakhulu. Nguye onomthwalo wokugqoka okunethezeka komkhiqizo, kuqinisekisa ukushintshaniswa okuvamile kokukhipha izinyembezi ngaphansi kwe-lens.

Izinzuzo eziyinhloko zama-lens

Iziguli eziningi ziphawula ukuthi ama-lens agxilile, asebenzayo gazi-permeable awancishiswa kakhulu ekuthuthukiseni, ekudaleni. Ngenxa yokuthi ububanzi bawo buyingcosana kune-lens esithambile, imikhiqizo enjalo ishiya indawo evulekile yomgwaqo we-cornea. Lokhu, futhi, akuphuli inqubo yokuqothula. Ziyakwazi ukumelana namaprotheni, ngakho-ke isikhathi sokusebenza okuphephile sikhula. Njengoba ukubunjwa okungenamanzi kwamanzi, ama-lens aqinile akakwazi ukuma, isiguli asidingi ukusebenzisa amaconsi athile okuphuthumayo. Kubalulekile ukuqaphela izindleko zabo zokusebenza kahle: ukuguqulwa kokubonakala okubonakalayo kusebenza njengesibonakaliso sokufaka esikhundleni. Njengoba i-astigmatism, i- lens yokuxhumana eqinile ikhonjiswa futhi . Ubufakazi beziguli bukhombisa ukuthi ukulungiswa kwe-lens elincane kunzima kunalesi simo, okuwukuphela kokukhetha ukusebenzisa imikhiqizo eqinile. Ukulungiswa kwe-Orthokeratology nakho kwande kakhulu. Kuhilela ukusetshenziswa kwamalensi aqinile ebusuku kuphela.

Orthokeratology. Kuyini okuyisisekelo sendlela

Lolu hlobo lokulungiswa kombono likuvumela ukuba ulugcine lubukhali emini, ebusuku udinga ukugqoka ama-lens akhethekile. Ngesikhathi sokulala, i-cornea yeso ishintshe, indawo yayo yokukhanya iyancipha. Leli fomu ligcinwa ngosuku olulandelayo. Njengomthetho, umphumela walokhu kulungiswa kungahlala izinsuku ezimbili. I-lens ebusuku ihle kakhulu kubantwana, iziguli ezinezinhlobo eziqhubekayo ze-myopia, ngokuphikisana nokusebenza ukuze kubuyiselwe umbono. Futhi, le ndlela ivame ukukhethwa ngabantu abasebenzayo abathile: abagijimi, ezempi, abakhi, njll. Ukuphikisana nokwelashwa kwe-orthokeratology yizifo ze-eye cornea, amajwabu amehlo, zonke izinqubo zokuvuvukala, isifo se-eye esomile.

Izikhathi ezimbi ekusetshenzisweni kwamalensi aqinile

Ngaphandle kwezinzuzo ezingenhla, i-lensi eqinile inezinselele zabo. Okokuqala, isikhathi esithile sokuguquguquka siyadingeka (cishe ngesonto). Ngemuva kokusetshenziswa, ukunganaki kuyanyamalala, kodwa ngisho nekhefu elincane ekugqokeni kudinga ukulimala okusha kumikhiqizo. Kunesilinganiso esithile sokuchithwa kwe-cornea, uma kusetshenziselwa ama-lens othintana ne-gas-permmeable contact. Ukuphawula kweziguli kubonisa ukuthi ukusetshenziswa kwezibuko ngemuva kwamalensi anjalo akuletha imiphumela efunayo: isithombe siyacaca, ubukhali buyancipha. Nokho, lokhu kuyimpumelelo yesikhashana. Emva kokubuyiselwa kwe-cornea, ungasebenzisa izibuko ngokuphepha, ngaphandle kokulahlekelwa ikhwalithi yombono. Futhi, inqubo yokukhetha izinto ide kakhulu, izindleko zabo zokuqala ziyoba umyalo wokuphakama okukhulu kunalokho kwe-lenses ezithambile.

Indlela yokukhetha i-lens permeable lens

Ukuze ukhethe kahle i-lens, kuqala kubalulekile ukubonisana nochwepheshe. Inquma ukubonakala okubonakalayo, izinga eliphezulu lokulungiswa. Ngosizo lwemishini ekhethekile, i-ophthalmologist yenza izinyathelo ezidingekayo ze-cornea yesiguli. Okulandelayo uzama ngezimbalwa ezimbalwa. Konke lokhu kudingekile kuyadingeka ukuze kulungiswe kahle lens. Ukwakhiwa kwama-lens okuxhumene nabo kwenziwa ngokuzimele, kuyilapho kunemibandela engaphezu kwengu-20 yeso. I-engineer ihlobisa ukuklanywa okudingekayo (indawo evulekile, indawo yesipelingi, indawo enqenqemeni). Okulandelayo, kumshini okhethekile, umkhiqizo ubukhali ngokugcwele ngokuhambisana nesakhiwo. Umkhiqizi odume kakhulu kule nkambu yinkampani yaseJalimane iWohlk. Lo mkhiqizi unikeza imikhiqizo yekhwalithi ephezulu. Njengomthetho, emva kwezinsuku ezingu-14 ungathola isethi ephelele yama-lens.

Ukunakekelwa kwansuku zonke kwama-lens oxhumana nabo okuqinile

Okokuqala, noma yiliphi i-lensi idinga ukuthobela imithetho yokuhlanzeka. Ngaphambi kokukhipha noma ukubeka izandla kumele kuhlanjwe nge-sese. Zisuse kahle ngethawula elimhlophe ukuze ugweme ukuwela emalini we-villi ehlukahlukene. Izitsha zokugcina kumele zigcinwe zihlanzekile. Kwabesifazane, kunezimiso ezikhethekile. Ama-Makeup kufanele asetshenziswe kuphela ngemva kokuthi i-lens igqoke. Ngakho, bese ususa ngemva kokukhipha umkhiqizo esweni. Futhi kuhlanzekile nsuku zonke kuyadingeka ukuze kube ne-lens eqinile yokuxhumana negesi. Isusa ukungcola, ukuphuza amanzi. Kanye ngesonto, ukuhlanza okujulile kwenziwa. Kumele uqaphele ukuthi awukwazi ukugubha ama-lensi kanzima kakhulu, ukuze ungaphazanyisi impahla yokukhanya. Kuze kube manje, ukuhlanza okuningi okusebenzayo kwamalensi okuxhumana okunzima kusetshenziswa kakhulu. Ivumela ukukhishwa ngokuphumelelayo kwamaprotheni amasheyithi (isibonelo, isisombululo seBoston Simplus), ayidingi ukuhlanzwa kwe-enzymatic eyengeziwe. Ibuye ihlukumeze ngokuphelele futhi ilulaze i-lens yokuxhumana. Ngokuhamba kwesikhathi, umkhiqizo unzima kakhulu ukuwuhlanza. Kulesi simo, i-lens ezinzima zingaphothulwa ku-laboratory ekhethekile.

Izidingo ezikhethekile zabanikazi bama-lens aqinile

Ukugqoka amalensi aqinile kubeka imithwalo ethile emithwalweni. Ukuvakashela ophthalmologist kufanele kube njalo. Lokhu kuzokwenza ukuthi ochwepheshe bahlole isimo samehlo. Lapho ushintsho oluncane esimweni samehlo, kubalulekile ukufuna iseluleko somchwepheshe. Ukwelapha okwesikhashana kuzogwema izimo ezifana ne-corneal edema, i-microbial keratitis, i-conjunctivitis, i-corneal ulcer, ukusabela kokugula. Ama-lens angama-gesi angapheliyo angama-lens ayisixazululo esihle kakhulu sokulungiswa kombono ezimweni eziningi, kodwa adinga ukunakekelwa okulungile nokucophelela.
