DI-efocus Ehlanganisiwe Yezingxenye Eziningi Amalensi aqanjwe ngenxa yokuthi kukhona inani lamalensi amancane abonakala ngeso lenyama kuma-engeli athile endaweni yelensi, asakazwa ngendlela yephoyinti, yingakho igama.I-Defocus Incorporated Multiple Segments Lens wuhlobo lwezibuko zokuvikela i-myopia nokulawula, ezakhiwe izindawo ezimbili.Enye indawo yokubona emaphakathi esetshenziselwa ukulungisa amaphutha e-refractive (i-myopia, ukubona kude kanye ne-astigmatism), kanti enye iyisikhungo esidlulela kuma-periphery welensi.Izindawo eziningi ze-myopic defocus zone.Lapho ogqokile ebheka izinto ezikude, i-defocus ehlanganiswe namalensi amasegimenti amaningi inganikeza umbono ocacile kanye ne-myopia defocus ngesikhathi esifanayo, futhi ingavimbela futhi ilawule ukukhula kwe-myopia ngenkathi ilungisa umbono.
Umgomo uwukusebenzisa indlela yemvelo yokuphendula iso - into eyenzeka nge-emmetropization, ukuze ukubona, ukuthuthukiswa kokubukwayo kanye nesithombe se-retinal yeso kuseduze nomphumela wokubukwa weso le-emmetropic.
Njengamanje, i-myopia yangempela yentsha ngokuvamile i-axial myopia, ebangelwa ukukhula kwe-eksisi yamehlo.Ngenxa yobude bebhola leso, indawo yesithombe iboniswa phambi kwe-retina.Lapho kulungiswa amalensi e-myopia avamile, ukulungiswa okucacile kuhloswe kuphela embonweni omaphakathi, futhi idizayini yelensi ngokwayo ikhula kancane kancane noma inyuse ngokungavamile izinga lendawo engaphandle kokukhanya okumaphakathi.Ngemva kokulungiswa, into efanayo ingaboniswa ku-fovea ye-macula ngaphandle kwenkinga, kuqinisekiswe ukubona okucacile.Kodwa-ke, into etholwe yi-peripheral retina ayikho ngqo ku-retina, kodwa ifanekiselwa ohlangothini olungemuva lwe-retina, Lokhu kuzophinde kuholele kulokho manje esikubheka njenge-hyperopia defocusing, okwamanje eyaziwa njengenye yezimbangela eziyinhloko ze-retina. ukwakheka kwe-myopia nokujula ngabacwaningi.Lokhu kungenxa yokuthi i-hyperopia defocusing ohlangothini olungemuva lwe-retina ikhuthaza ukukhula kwe-eksisi yeso ngaseceleni elingemuva, okuholela ekukhuleni kwe-axial nokujula okuqhubekayo kwe-myopia.
Ilensi encane esendaweni ye-defocus iklanyelwe ngokukhethekile ukuthi ibe nedigri ehlukile kunelensi eyodwa endaweni yokulungisa, okubangela ukuba isithombe siwe phambi kwe-retina, okuholela ku-myopia defocus futhi inikeze isignali ku-axis yeso phambili, ukufeza. umphumela wokubambezela ukujula kwe-myopia.
Inzuzo:
1.Umphumela wokulawula i-myopia usobala: umthelela wokulibazisa ekukhuleni kwedigri ye-myopia uphezulu njengo-59%, futhi umphumela wokulawula ekukhuleni kwe-axial uphezulu njengo-60%.
2.Ukufaka okulula: Amalensi e-myopia defocus enamaphuzu amaningi awuhlobo olukhethekile lwelensi yokugxila eyodwa, futhi ukufakwa kulula.
I-3.Induduzo ephezulu: i-multi-point myopia defocus lens ayinayo indawo ye-astigmatism futhi ayixhumani neso lomuntu.Ngokungafani nama-lens oxhumana naye, athinta i-cornea, ngeke abangele ukungakhululeki.
4.Ukunakekelwa okulula: Uma kuqhathaniswa namanye ama-lens, njengamalensi e-orthokeratology, adinga ukugeza izandla kanye nokubulala amagciwane njalo lapho ekhishwa futhi efakwa, futhi ukugcinwa kwamalensi kudinga izixazululo zokunakekelwa okukhethekile.
5.Umphumela wokulibaziseka we-myopia uphezulu njengo-59%, futhi umphumela wokulawula ukukhula kwe-axial uphezulu njengo-60%.
