●Yintoni i-cataract?
Iliso lifana nekhamera esebenza njengekhamera ekwiliso. Xa umncinci, i-lens iyabonakala, i-elastic kunye ne-zoomable. Ngenxa yoko, izinto ezikude nezikufuphi zinokubonwa ngokucacileyo.
Ngokukhula, xa izizathu ezahlukahlukeneyo zibangela utshintsho lwe-lens permeability kunye nokuphazamiseka kwe-metabolic, i-lens ineengxaki ze-protein denaturation, i-edema kunye ne-epithelial hyperplasia. Ngeli xesha, i-lens eqhele ukucaca njengejeli iya kuba yi-turbid opaque, oko kukuthi nge-cataract.
Kungakhathaliseki ukuba i-opacity ye-lens inkulu okanye encinci, ichaphazela umbono okanye cha, ingabizwa ngokuba yi-cataract.
● Iimpawu ze-cataract
Iimpawu zokuqala zecataract azibonakali kakuhle, kuphela ngombono ongephi. Izigulana zinokuthi ngempazamo ziyithathe njenge-presbyopia okanye ukukhathala kwamehlo, ngokulula ukuphosa ukuxilongwa. Emva kwe-metaphase, i-opacity ye-lens yesigulane kunye neqondo lokungaboni kakuhle liyancipha, kwaye kunokuba nemvakalelo engaqhelekanga efana ne-double strabismus, i-myopia kunye ne-glare.
Iimpawu eziphambili zecataract zezi zilandelayo:
1. Ukungaboni kakuhle
I-opacity ejikeleze i-lens ayinakuchaphazela umbono; nangona kunjalo i-opacity kwindawo esembindini, nokuba i-scope incinci kakhulu, iya kuchaphazela kakhulu umbono, nto leyo ebangela ukwenzeka kokungaboni kakuhle kunye nokwehla komsebenzi obonakalayo. Xa i-lens inamafu kakhulu, umbono unokuncitshiswa ube yimbono yokukhanya okanye nokuba yimfama.
2. Ukunciphisa ubuntununtunu bokuchasanisa
Kubomi bemihla ngemihla, iliso lomntu lifuna ukwahlula izinto ezinemida ecacileyo kunye nezinto ezinemida engacacanga. Olu hlobo lokugqibela lwesisombululo lubizwa ngokuba bubuntununtunu bokuchasanisa. Izigulana zeCataract zisenokungaziva zisehla ngokubonakalayo, kodwa uvakalelo oluchaseneyo luncitshiswe kakhulu. Izinto ezibonwayo ziya kubonakala zinamafu kwaye zifuze, zibangele isenzeko sehalo.

3. Guqula ngeSense yoMbala
Ilensi yamafu yesigulana sorhatyazo ifunxa ngakumbi ukukhanya okuluhlaza okwesibhakabhaka, nto leyo eyenza iliso lingabi namvakalelo kwimibala. Utshintsho kumbala we-nucleus yelensi luchaphazela umbono wombala, kunye nokulahleka kombala ocacileyo (ingakumbi oluhlaza okwesibhakabhaka kunye nohlaza) emini. Ngoko izigulane ze-cataract zibona umfanekiso ohlukileyo kubantu abaqhelekileyo.

●Indlela yokukhusela kunye nokunyanga i-cataract?
I-Cataract sisifo esixhaphakileyo kwaye sihlala sivela kwi-ophthalmology. Olona nyango lulo lwecataract lutyando.
Izigulana zokuqala ze-cataract azinayo impembelelo enkulu kubomi bombono wesigulane, ngokubanzi unyango aluyomfuneko. Bangakwazi ukulawula umlinganiselo wenkqubela phambili ngokusebenzisa iyeza lamehlo, kwaye izigulane ezinotshintsho lwe-refractive kufuneka zinxibe iiglasi ezifanelekileyo zokuphucula umbono.
Xa i-cataract iba mandundu kwaye umbono ongalunganga uchaphazela ubomi bemihla ngemihla, kunyanzelekile ukuba kwenziwe utyando. Iingcali zichaza ukuba umbono we-postoperative awuzinzile kwixesha lokuvuselela ngaphakathi kwe-1 inyanga. Ngokuqhelekileyo izigulane kufuneka zenze uhlolo lwe-Optometry kwiinyanga ezi-3 emva kotyando. Ukuba kuyimfuneko, nxiba iiglasi (i-myopia okanye iglasi yokufunda) ukulungelelanisa umbono okude okanye okufutshane, ukuze ufezekise umphumo ongcono wokubonwayo.
