●Kuyini i-cataract?
Iso lifana nekhamera lapho ilensi isebenza njengelensi yekhamera esweni. Uma liselincane, ilensi iyabonakala, iyanwebeka futhi iyakwazi ukusondeza. Ngenxa yalokho, izinto ezikude neziseduze zingabonakala kahle.
Njengoba iminyaka ikhula, lapho izizathu ezahlukahlukene zibangela ushintsho ekungeneni kwelensi kanye nokuphazamiseka kwe-metabolic, ilensi inezinkinga zokuguquka kwamaprotheni, ukuvuvukala kanye ne-epithelial hyperplasia. Okwamanje, ilensi eyayicacile njengejeli izophenduka i-opaque enamafu, okungukuthi nge-cataract.
Kungakhathaliseki ukuthi ukungabonakali kwelensi kukhulu noma kuncane, kuthinta umbono noma cha, kungabizwa ngokuthi i-cataract.
● Izimpawu ze-cataract
Izimpawu zokuqala ze-cataract ngokuvamile azibonakali, kuphela uma umbono ufiphele kancane. Iziguli zingase zikubone ngephutha njenge-presbyopia noma ukukhathala kwamehlo, okungase kuphuthelwe kalula ukuxilongwa. Ngemva kwe-metaphase, ukufiphala kwelensi yesiguli kanye nezinga lombono ofiphele kuyakhula, futhi kungase kube nomuzwa ongajwayelekile njenge-double strabismus, i-myopia kanye ne-glare.
Izimpawu eziyinhloko ze-cataract yilezi ezilandelayo:
1. Ukubona Okungaphilile
Ukungacaci kahle okuzungeze ilensi akukwazi ukuthinta umbono; noma kunjalo, ukungabonakali kahle engxenyeni ephakathi, noma ngabe ububanzi buncane kakhulu, kuzothinta kakhulu umbono, okubangela ukuthi umbono ofiphele kanye nokusebenza kokubona kwehle. Uma ilensi inamafu kakhulu, umbono ungancishiswa ube ukubona kokukhanya noma ngisho nokungaboni.
2. Ukunciphisa ukuzwela kokungafani
Empilweni yansuku zonke, iso lomuntu lidinga ukuhlukanisa izinto ezinemingcele ecacile kanye nezinto ezinemingcele efiphele. Uhlobo lokugcina lokuxazulula lubizwa ngokuthi ukuzwela kokungafani. Iziguli ze-cataract zingase zingazizwa ziwohloka ngokusobala kokubona, kodwa ukuzwela kokungafani kuncishisiwe kakhulu. Izinto ezibonakalayo zizobonakala zinamafu futhi zifiphele, okubangela isenzakalo se-halo.

3. Shintsha Nge-Color Sense
Ilensi enamafu yesiguli esine-cataract imunca ukukhanya okuluhlaza okwesibhakabhaka okwengeziwe, okwenza amehlo angazweli kakhulu emibala. Izinguquko embala we-nucleus walensi nazo zithinta umbono wombala, ngokulahlekelwa ukukhanya kwemibala (ikakhulukazi eluhlaza okwesibhakabhaka nohlaza) emini. Ngakho-ke iziguli ezine-cataract zibona isithombe esihlukile kubantu abavamile.

●Ungazivikela kanjani futhi uphathe kanjani i-cataract?
I-cataract yisifo esivamile futhi esivame ukwenzeka kwezokwelapha amehlo. Ukwelashwa okuyinhloko kwe-cataract ukuhlinzwa.
Iziguli ezinesifo sokuguga kwamehlo ezisakhula azinawo umthelela omkhulu empilweni yombono wesiguli, ngokuvamile ukwelashwa akudingekile. Zingalawula izinga lokuthuthuka ngemithi yamehlo, futhi iziguli ezinezinguquko zokubona kufanele zigqoke izibuko ezifanele ukuze zithuthukise umbono.
Uma i-cataract iba yimbi kakhulu futhi umbono ongemuhle uthinta kakhulu impilo yansuku zonke, kuyadingeka ukuthi kwenziwe ukuhlinzwa. Ochwepheshe baveza ukuthi umbono wangemva kokuhlinzwa awuzinzile esikhathini sokululama phakathi nenyanga eyodwa. Ngokuvamile iziguli kudingeka zenze ukuhlolwa kwamehlo ezinyangeni ezi-3 ngemuva kokuhlinzwa. Uma kudingeka, gqoka izibuko ezimbili (i-myopia noma ingilazi yokufunda) ukuze ulungise umbono okude noma oseduze, ukuze uthole umphumela ongcono wokubona.
