Astigmatism ye-Hypermetropic

I-astigmatism ye-Hypermethropic ingenye yeziphambeko zombono ngokubhekwa phambili. Ezimweni eziningi, igeleza ngokungaqondakali komuntu ogqokayo, kodwa ngezinye izikhathi kungabangela ukucasuka nokukhwabanisa okukhulu. I-astigmatism ye-hypermethropic kokubili amehlo ayikho okwenzekayo, ngokuvamile isifo siqala ngeso elilodwa kuphela.

Izici ezicasulayo ze-astigmatism

I-Astigmatism iyinkinga yokubona lapho amazinga ahlukene okubona okubonakalayo nokubukeka kwezinto ezibonakalayo ekhula ngamameridiya ahlukene e-eyeball, ngenxa yalokho, iso lugxile emaphuzu amabili, okuphuma kuyo bese ukhathala futhi umbono uqala ukunciphisa kakhulu. I-Astigmatism e-hypermetropia, okungukuthi, ukubhekwa phambili, ingaba yindlala, futhi kulokhu umbono kancane kancane uboniswa, futhi kungabangelwa izinhlobo ezihlukahlukene zokuhlukunyezwa. Nazi izinhlobo eziyinhloko zokugula:

• astigmatism elula ye-hypermetropic;
• i-astigmatism ye-hypermetropic enzima;
• i-astigmatism ye-hypermetropic eqondile.

Njengoba i-astigmatism elula kwesinye se-meridians iso, i- hyperopia iqala, kanti ngakolunye uhlangothi, umbono ugcinwa ezingeni elithi "eyodwa", evamile. Eyinkimbinkimbi kuzo zombili i-meridians ukubhekwa kwezinto ezibukhali kuzinzile. Esimweni sokuqala, ukucaca kombono akukwazi ukunciphisa iminyaka futhi lesi sifo sitholakale ngengozi. Uphawu oluvame kakhulu lukhanda olunzima lomsuka ongaziwa.

Esimweni sesibili, iziphambeko ezibonakalayo zibonakala esibhedlela ngesikhathi esisodwa, futhi ngokuvamile i-astigmatism ye-hypermetropic ihambisana ne-amblyopia. Lokhu okuthiwa "i-lazy iso" syndrome, lapho amadivaysi e-optical engathinti ama-acuity abukwayo, izibuko noma amalensi akwenza ngcono isimo. Nazi izizathu eziyinhloko zalesi simo esibuhlungu:

• umehluko wobuhlobo obusweni obususweni;
• ukulahlwa okubonakalayo kwesinye iso;
• i-strabismus ;
• ukuphazamiseka nokukhathazeka kokukhathazeka kwazo zonke izinhlobo;
• ukwephulwa kwesibambiso.

Kungenzeka yini ukwelapha i-astigmatism ye-hypermetropic eqondile?

I-astigmatism elula ekwelapheni nasekulungiseni akudingi, ngefomu eziyinkimbinkimbi kunconywa ukugqoka izibuko ukuze unike amehlo ukuphumula okudingekayo. Ngosizo lwama-lens nezibuko, umphumela wokulungisa kule nkinga awukwazi ukuhlinzeka, indlela kuphela ephumelelayo yokuphulukisa i-astigmatism eyinkimbinkimbi iyasebenza namuhla. Nakhu okuthandwa kakhulu kubo:

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

Njengendlela yokusiza, ukwelashwa kwe-hardware kungacelwa.
