Ukugqoka okanye ukungabandakanyi iilensi kunye ne- astigmatism - into ebalulekileyo kumntu wonke. Kuze kube kutshanje, izigulane ezinokuxilongwa okunjalo zazingenaso ithuba lokubona ngcono ngaphandle kokusebenzisa iiglasi. Okokuqala kwakukho iilensi ezinzima onokuzilungisa njenge-astigmatism, kwaye kwiminyaka embalwa edlulileyo, abavelisi bafunde indlela yokwenza i-lens torsi. Kancinci, uludwe lwezinto ezintle zokulungiswa kwe-astigmatism kunye neelensi zokunxibelelana zanda, uludwe lweempembelelo - lufutshane. Nangona kunjalo, basoloko baninzi.
Izixhobo zokukhetha iilensi zokudibanisa ze-astigmatism
Kukho izicwangciso ezintathu eziphambili zokugqoka ii-lens zokuthintana ne-astigmatism:
- I-lens zoxhumo ezinobungozi zokulungisa ukubonakala okubonakalayo kunye neengqungquthela, iilensi zazo ziba neeflasks zokulungisa i-astigmatism. Oku kunciphisa umthwalo kwamehlo kunye nobungozi beengxaki.
- Iilensi ezinobumba zisesigxina, ezichanekileyo njenge-astigmatism kunye ne- myopia .
- I-toric ezinamandla okanye ii-lens ezijikelezayo eziphucula ubunono obubonakalayo kwaye ziqwalasele njenge-astigmatism.
Indlela yokuqala ikhuselekileyo kwaye ikhululekile kwamehlo. Ekubeni i-astigmatism ishintsho ekujoliswe kuyo kwiso, akufuneki ukugqoka ii-lens kunye neziglasi eziphelisa le ntsilelo. Oku kufakwe intloko kunye nokuphulwa kwe-lens. Siyabulela kule ndlela, siyaqhubeka sibona ngokubonga iilensi, nangona sinika iliso ithuba lokuphumula, sithatha iziglasi zokulungisa izigulane. Ngelishwa, le ndlela ayithandwa kakhulu.
Iilensi zokuxhamla ezinobungozi kunye ne-astigmatism zikulungele ukuba aziphazamisi iinkqubo ze-metabolic kwiso kwaye zibonelela ngokubanzi kwamehlo omabili. Ngenxa yokuba ayinayo i-spycle kodwa i-toric, kufuneka ithathelwe ingqalelo ukuze kuqinisekiswe ukuba i-lens igcina isikhundla esigxina kwi-cornea kwaye ayihambeli. Ngokuqhelekileyo, imithetho yokugqoka ezi iilensi zifana neefowuni eziqhambileyo zoqhagamshelwano.
Iilensi zoqhagamshelwano ezinzima kufuneka zisuswe ebusuku. Banobuchule obukhulu bokuthonya i-astigmatism, kodwa amehlo aya kufuna ukuphumla okungaphezulu.
Indlela yokukhetha iilensi zokunxibelelana ezifanelekileyo njenge-astigmatism, kuxhomekeke kwizinto ezininzi, kodwa i-underlying one kulesi si thuzelo sakho. Eyona mpu melelo kakhulu kwi-optical point view, iilensi zingonakalisa ukuba zivakalelwa ngokucacileyo kwiso.
Iinkonzo kunye neNgqungquthela
Ukuba unokungabaza ukuba unokugqoka ii-lens zokudibanisa njenge-astigmatism, qwa lasela uluhlu lwezinto ezingonakaliyo kule ndlela:
- ubuchule obuphezulu bokuphuhliswa kweenkqubo ezivuthayo ngenxa yefomu engavumelekanga yelensi;
- ukwanda kwe-myopia ngenxa yokuphazamiseka kokuhamba kwe-oksijeni kwi-cornea;
- ubunokwenzeka bokutshintsha isimo se-cornea;
- utshintshe ubude bendawo ye-cornea, ehambelana nokukhethwa kwamandla alungelelwano olwenziwe kwilensi.
Ngelo xesha, iingenelo zithetha zona:
- ukuba kunokwenzeka ukulungisa ngisho ne-astigmatism ye-corneal ephezulu;
- utshintsho oluncinci kummandla wombono;
- mbono we binocular;
- Ubuncinane bomhlaba obonakalayo kunye nokuphazamiseka.
