DAmalensi e-efocus Incorporated Multiple Segments aqanjwe ngoba kunenqwaba yamalensi amancane abonakala ngeso lenyama ngama-engeli athile ebusweni belensi, asakazwa ngesimo sephuzu, yingakho igama lawo libizwa kanjalo. Amalensi e-Defocus Incorporated Multiple Segments awuhlobo lwezibuko zokuvimbela nokulawula i-myopia, ezakhiwe yizindawo ezimbili. Enye indawo ephakathi nendawo esetshenziselwa ukulungisa amaphutha okukhanya (i-myopia, ukubona kude kanye ne-astigmatism), kanti enye iyindawo ephakathi nendawo efinyelela emngceleni belensi. Izindawo eziningi ze-myopic defocus. Lapho umuntu ogqokile ebheka izinto ezikude ezahlukene, amalensi e-defocus afakwe ama-multiple segments anganikeza umbono ocacile kanye ne-myopia defocus ngesikhathi esifanayo, futhi angavimbela futhi alawule ukukhula kwe-myopia ngenkathi elungisa umbono.
Umgomo uwukusebenzisa indlela yemvelo yokuphendula iso - into eyenziwa yi-emmetropization, ukuze ukubona, ukuthuthukiswa kokubona kanye nomfanekiso we-retina weso kusondele kakhulu kumphumela wokubona weso le-emmetropic.
Njengamanje, i-myopia yangempela yentsha ikakhulukazi i-axial myopia, ebangelwa ukukhula kwe-axis yeso. Ngenxa yokwelulwa kwebhola leso, indawo yesithombe iboniswa phambi kwe-retina. Lapho kulungiswa amalensi avamile e-myopia, ukulungiswa okucacile kuhloselwe kuphela umbono ophakathi, futhi ukwakheka kwelensi ngokwako kwandisa kancane kancane noma kwandisa ngokungajwayelekile izinga lendawo engaphandle kokukhanya okuphakathi. Ngemva kokulungiswa, into efanayo ingaboniswa ku-fovea ye-macula ngaphandle kwenkinga, okuqinisekisa umbono ocacile. Kodwa-ke, into etholwa yi-retina yangaphandle ayikho ngqo ku-retina, kodwa iboniswa ohlangothini olungemuva lwe-retina. Lokhu kuzophinde kuholele kulokho esikubheka manje njenge-hyperopia defocusing, okwamanje okuqashelwa njengenye yezimbangela ezinkulu zokwakheka nokujula kwe-myopia ngabacwaningi. Lokhu kungenxa yokuthi i-hyperopia defocusing ohlangothini olungemuva lwe-retina ivuselela ukukhula kwe-axis yeso iye ohlangothini olungemuva, okuholela ekukhuleni kwe-axial kanye nokujula okwengeziwe kwe-myopia.
Ilensi encane endaweni ye-defocus iklanyelwe ngokukhethekile ukuba ibe nezinga elihlukile kunelensi eyodwa endaweni yokulungisa, okubangela ukuthi isithombe siwe phambi kwe-retina, okuholela ekususweni kwe-myopia futhi kunikeze isignali ku-axis yeso phambili, okufeza umphumela wokulibazisa ukujula kwe-myopia.
Inzuzo:
1. Umphumela wokulawula i-myopia usobala: umphumela wokulibazisa ekukhuleni kwezinga le-myopia uphezulu ngamaphesenti angama-59, kanti umphumela wokulawula ekukhuleni kwe-axial uphezulu ngamaphesenti angama-60.
2. Ukufakwa okulula: Amalensi e-defocus e-myopia enamaphuzu amaningi awuhlobo olukhethekile lwelensi eyodwa yokugxila, futhi ukufakwa kulula.
3. Induduzo ephezulu: amalensi e-myopia defocus anamaphuzu amaningi awanayo indawo ye-astigmatism futhi awathinti iso lomuntu. Ngokungafani namalensi okuxhumana, athinta i-cornea, ngeke abangele ukungakhululeki.
4. Ukunakekelwa okulula: Uma kuqhathaniswa namanye amalensi, njengamalensi e-orthokeratology, adinga ukugeza izandla nokubulala amagciwane njalo lapho ekhunyulwa futhi efakwa, kanti ukunakekelwa kwamalensi kudinga izixazululo zokunakekelwa okukhethekile.
5. Umphumela wokulibazisa we-myopia ufinyelela ku-59%, kanti umphumela wokulawula wokukhula kwe-axial ufinyelela ku-60%.
