Lens Scleral ukuthuthukisa futhi ushintshe umbala wamehlo

Lens ukumboza cornea kanye neso ingxenye ebonakalayo amaprotheni abizwa ngokuthi - lens scleral. Kahle zifakwa lens scleral abasakwazi ukhululekile ngoba begqoke izigqoko zeluliwe, naphezu yobukhulu bawo. Ngokuvamile, lokhu imodeli isetshenziswa izifo iso kanye zamehlo azalwa naso esweni e ngezinhloso ayeyisimonyo.

lens Scleral - izinzuzo

Izinzuzo onobuhle scleral zihlanganisa:

1. esikhoselweni ukukhubazeka yezimonyo esweni obonakele.

2. Awokuzenzisa uhlobo amehlo enempilo.

3. kwaqedwa ulahlekile esincane iso.

4. ngokugxilisa umfundi yokufakelwa endaweni efanele ngesikhathi squint.

lens Scleral - nebubi

1. main "omubi" lens scleral wukuthi Ukukhetha yabo kuthatha isikhathi eside, eliphezulu imishini umkhiqizi.

2. Ubungozi edema corneal. lens Scleral ikhiqizwa PPMA impahla uyavikeleka kunomoya-mpilo. Lokhu kuholela ingozi edema corneal. PPMA impahla kuyamukeleka kunjalo, uma ufuna ukushintsha ukuma. model, workpieces kungase kushintshwe. lens Scleral "phinda" kobuso iso nokubonisa abantu abaphethwe keratoconus (ugobile corneal).

3. Long senqubo yokukhiqiza (ngokwesilinganiso sezinyanga eziyisithupha). Phakathi nale nkathi, mlando elandelayo ingafinyelelwa:

- Ukuthatha izilinganiso zobukhulu ngqo.

- fitting lens okokuqala ngale. Ngemva kwalokho isiguli uyamthatha naye ukuhlukanisa nokufakwa. Inqubo yokufunda ukuphila nesimo esithile kuyi-lens scleral esokuba ngabanye kanye luncike degree of nozwela iso.

- Ngesikhathi ngifika ngokulandelayo oluqanjwe ukubukela degree lesiguli okuzivumelanisa.

- ukwenza izinguquko ezincane izilinganiso imodeli ukuze kuzuzwe imiphumela esiphezulu. I-lens kufanele kube ntofontofo kakhulu futhi ube nesikhathi ongeke ukubukeka yobuhle.

- I kufaneleka sokugcina. Kulesi sigaba, ukwethulwa kwe-zokugcina "imivimbo" futhi ezenziwe wokugubha phambi ingxenye.

- Isicelo umbala. It idlulisela yonke imininingwane ye iso enempilo: i-semithambo net, umthunzi nombala elungisa amaprotheni ingxenye.

lens Scleral ukunikeza umphumela yezimonyo, lapho ezizungezile, ezimweni eziningi, lapho engayitholi umehluko phakathi iso evamile futhi iso ne-lens. ukusebenza kwesikhathi ukukhiqizwa iminyaka emihlanu.

lens Scleral ezenziwe ngezinto eliqinile ukuze umoya-mpilo, kunganciphisa ematfuba ukuvuvukala corneal esiphansi. Nokho, izinto ezikhona igesi permeable - ngepulasitiki ukushisa ukumelana, okuyinto akukwazi ukucubungulwa usebenzisa ukushisa futhi usigcine. Leli qiniso kakhulu kunciphisa kungenzeka ukusetshenziswa lens anjalo keratoconus. I preform liyadingeka ukusingatha umshini ekhethekile futhi egcizelele ngaphansi ukuma iso esebenzisa imishini yokuhlola.

Lenses, okwandisa iso

onobuhle Magnifying azisetshenziselwa ngenjongo ukulungiswa noma ukuqedwa ukukhubazeka, futhi kukhona zokuhlobisa. lens anombala ukuthuthukisa iso ungaba ifomu ezihlukahlukene izinhliziyo, ihluzo, iwebhu, imiqhele. lens okunjalo ukwandisa iso pheze ngesiquntu. Amamodeli bangakhetha ngokusho ukunambitheka yakho, hlanganisa them timphahla tekubhukusha zomkhosi noma ingubo. Ungase futhi ukuthenga lens ukuthi ukushintsha umbala umfundi. Ngo lens ayatholakala emakhemisi ngoba brown amehlo. Nokho, ziyisici imbe eqolo ngaphezu for ukukhanya.

Contact lens, sandla ukwanda iso, okumele abe nomkhawulo ukugqoka uma ngokucasuka ububomvu, ukufiphala noma ukopha yesithombe. Kufanele kuqondwe ngokucacile ukuthi imikhiqizo efana asetshenziswa behlobisa amazwi emehlweni, ukwehluka. Ngu ukulungiswa izesekeli scleral zokuhlobisa ngalutho.
