Hypermetropic astigmatism

I-hypermethropic astigmatism yenye yezinto eziphambene nombono onokujonga. Kwiimeko ezininzi, ihamba ngokungaqondakaliyo, kodwa ngamanye amaxesha inokubangela ukukhungatheka kunye nentloko. I-hypermethropic astigmatism yamehlo omabini ayenzekanga, ngokuqhelekileyo eso sifo siphula kwelinye iliso.

Imiba echukumisayo ye-astigmatism

I-Astigmatism ibonakaliswa yimbonakalo apho amazinga ahlukeneyo okujonga kunye nokugqithisileyo ekhula kwiimeridi ezahlukeneyo zamehlo, ngenxa yoko, iliso lijolise kumaphuzu amabini, apho ludiniwe kwaye umbono uqala ukuhla kakhulu. I-Astigmatism kwi-hypermetropia, oko kukuthi, ukujonga phambili, ingaba yintsapho, kwaye kulo mbono umgangatho wenkqubela-mgangatho uphawuleza, kwaye ungabangelwa iintlobo ezahlukeneyo zexinzelelo. Nazi iindlela eziphambili zokugula:

• i-hypermetropic astigmatism;
• i-hypermetropic astigmatism;
• i-hypermetropic astigmatism ngqo.

Nge-astigmatism elula kwenye yeemeridians zeso, i- hyperopia ikhula, ngelixa kwelinye, umbono ugcinwa kwinqanaba "elilodwa", eliqhelekileyo. Kwiinkalo zombini i-meridians ukujonga ubude bume. Kwimeko yokuqala, ukucaca kombono akukwazi ukuncitshiswa iminyaka kwaye isifo sifumaneka ngethuba. Uphawu oluqhelekileyo luyintloko yamakhanda engaziwayo.

Kwimeko yesibini, iimpembelelo ezibonakalayo zibonakala kwiigulane kanye, kwaye i-astigmatism ye-hypermetropic ihlala ihamba ne-amblyopia. Oku kubizwa ngokuthi "iso lesiso" isifo, xa amadivaysi ombonakalo ayichaphazeli ubuninzi bokubonakala, akukho maglasi okanye iilensi eziphucula imeko. Nazi izizathu eziphambili zezi zimo ezibuhlungu:

• Ukwahlukana komntwana kwintlungu ye-eye refractivity;
• ukungabikho komboniso omnye kwamehlo;
• i-strabismus ;
• ingxaki kunye neengxaki zeentlungu zeentlobo zonke;
• ukuphulwa komthetho.

Ngaba kunokwenzeka ukuphilisa ubunzima be-hypermetropic astigmatism?

I-astigmatism elula kwonyango kunye nokulungiswa akuyidingi, kunye neendlela ezinzima kunconywa ukuba ugqoke iilazi ukwenzela ukunika amehlo zokuzonwabisa. Ngoncedo lwama-lens kunye neziglasi, umphumo wokulungiswa kwingxaki ayikwazi ukunikezelwa, indlela efanelekileyo yokuphilisa i-astigmatism eyinkimbinkimbi yonyango namhlanje. Nazi ezinye ezithandwa ngabo:

• laser thermokeratoplasty;
• thermokeratocoagulation;
• i-hypermetropic laser keratomileusis.

Njengendlela yobancedisi, unyango lwe-hardware lunokumiselwa.
