DIilensi ze-efocus Incorporated Multiple Segments zibizwa ngokuba zininzi iilensi ezincinci ezibonakala emehlweni kwi-engile ethile kumphezulu welensi, ezisasazwa ngendlela ethile, yiyo loo nto zibizwa njalo. Iilensi ze-Defocus Incorporated Multiple Segments luhlobo lweeglasi zesakhelo sokuthintela i-myopia kunye nokulawula i-myopia, ezenziwe ziindawo ezimbini. Enye yindawo ephakathi ye-optical esetyenziselwa ukulungisa iimpazamo zokuhombisa (i-myopia, ukubona kude kunye ne-astigmatism), kwaye enye yindawo ephakathi efikelela kumda welensi. Iindawo ezininzi ze-myopic defocus zones. Xa umntu onxibe izinto ezikude, iilensi ze-defocus ezifakwe kwiilensi ezininzi zinokubonelela ngombono ocacileyo kunye ne-myopia defocus ngaxeshanye, kwaye zinokuthintela kwaye zilawule ukukhula kwe-myopia ngelixa zilungisa umbono.
Umgaqo kukusebenzisa indlela yendalo yokuphendula iliso - into eyenziwa yi-emmetropization, ukuze ukubona, uphuhliso lokubona kunye nomfanekiso we-retina weliso zisondele kakhulu kwisiphumo sokubona seliso le-emmetropic.
Okwangoku, i-myopia yokwenyani yolutsha ikakhulu yi-axial myopia, ebangelwa kukukhula kwe-axis yeliso. Ngenxa yokwandiswa kwebhola yeliso, indawo yomfanekiso iboniswa phambi kwe-retina. Xa kulungiswa iilensi ze-myopia eziqhelekileyo, ukulungiswa okucacileyo kujoliswa kuphela kumbono ophakathi, kwaye uyilo lwelensi ngokwalo luyanda kancinci okanye ngokungekho mthethweni lunyusa inqanaba lendawo engaphandle kokukhanya okuphakathi. Emva kokulungiswa, into efanayo inokujoliswa kwi-fovea ye-macula ngaphandle kwengxaki, ukuqinisekisa umbono ocacileyo. Nangona kunjalo, into efunyenwe yi-peripheral retina ayikho ngqo kwi-retina, kodwa iboniswa kwicala elingasemva le-retina. Oku kuya kukhokelela kwinto esiyithatha ngoku njenge-hyperopia defocusing, okwangoku ebonwa njengenye yezona zinto ziphambili zokwakheka kwe-myopia kunye nokunzulu ngabaphandi. Oku kungenxa yokuba i-hyperopia defocusing kwicala elingasemva le-retina ivuselela ukukhula kwe-axis yeliso ukuya kwicala elingasemva, okukhokelela ekukhuleni kwe-axial kunye nokunzulu ngakumbi kwe-myopia.
Ilensi encinci kwindawo ye-defocus yenzelwe ngokukodwa ukuba ibe nomlinganiselo owahlukileyo kunelensi enye kwindawo yokulungisa, nto leyo ebangela ukuba umfanekiso uwe phambi kwe-retina, nto leyo ebangela ukuba i-myopia ingabi nafocus kwaye inike isignali kwi-axis yeliso phambili, nto leyo efezekisa isiphumo sokulibazisa ukujula kwe-myopia.
Inzuzo:
1. Isiphumo sokulawula i-myopia sicacile: isiphumo sokulibazisa ekukhuleni kwe-myopia degree siphezulu njenge-59%, kwaye isiphumo solawulo ekukhuleni kwe-axial siphezulu njenge-60%.
2. Ukufakelwa okulula: Iilensi ze-myopia defocus ezinee-point ezininzi luhlobo olukhethekileyo lwelensi enye yokugxila, kwaye ukufakwa kulula.
3. Intuthuzelo ephezulu: iilensi ze-myopia defocus ezineengongoma ezininzi azinandawo ye-astigmatism kwaye azifiki kwiliso lomntu. Ngokungafaniyo neelensi zoqhagamshelwano, ezifikelela kwi-cornea, aziyi kubangela ukungonwabi.
4. Ukunyamekela okulula: Xa kuthelekiswa nezinye iilensi, ezifana neelensi ze-orthokeratology, ezifuna ukuhlamba izandla kunye nokubulala iintsholongwane ngalo lonke ixesha xa zikhutshwa kwaye zinxitywa, kwaye ukugcinwa kweelensi kufuna izisombululo zokhathalelo olukhethekileyo.
5. Isiphumo sokulibazisa se-myopia sifikelela kwi-59%, kwaye isiphumo sokulawula ukukhula kwe-axial sifikelela kwi-60%.
