Kungani halo umphumela ibonakala ngemuva laser umbono ukulungiswa?

Emakhaya layimfica kulawa iziguli eziyishumi Ngahlinzwa laser umbono, umbiko imiphumela eyanelisayo. Kodwa amaphesenti abalulekile iziguli uhlangabezana ukungakhuli entsha ezibukwayo. Ngokwesibonelo, babona halos emhlabeni ikhanyisa sikhatsi lesingaba tinyanga letisitfupha emva inqubo, ngokusho kocwaningo entsha.

Imiphumela engemihle lokuhlinzwa

"Nakuba ukuhlinzwa laser bekulokhu kubhekwa njengendlela iphephile futhi isebenza ngempumelelo, inani elincane, kodwa abalulekile iziguli ukubika imiphumela nasezinkingeni ezilandela ngemva kokuhlinzwa ezifana ukukhanya, halos kanye nezinye izimpawu, kodwa futhi ukhuluma izinyembezi," - wathi Dr. Christopher Starr. He is likaprofesa wezifo zamehlo esibhedlela e-New York.

"Le miphumela ngokuvamile uzikhonze isikhathi noma ngesikhathi inqubo yokwelapha, okungase kuthathe izinyanga ezingu-12, noma futhi iqedwe ngekusebentisa tinchubo eyengeziwe uma kunesidingo", - uthe Starr, owayebizwa akazibandakanyi isifundo esisha.

Kweminingi iziguli wahlola angaphansi kwamaphesenti 1 ubike inkinga ukuthi ethinta ngayo ukuphila kwazo zonke izinsuku. Noma kunjalo, lezi zinkinga ingase ivame kakhulu kunalokho okwake kwacatshangwa.

Yiziphi izinkinga enza ukuhlinzwa laser

ukuhlinzwa Laser asetshenziselwa nokwelapha izinkinga ezifana myopia futhi hyperopia, futhi astigmatism (isifo samehlo lapho isithombe siphazamisekile bezibona). Izigidi zabantu abane, ababenethemba lokuthola ukuqeda izibuko noma ama-contact lens, wazibonela ukuhlinzwa laser kusukela ekuqaleni ukuthuthukiswa kwawo eminyakeni engaphezu kwengu-20 edlule.

Ukuze ufunde kabanzi mayelana imiphumela lolu hlobo ukwelashwa, Ukuphathwa American ngaphansi ukulawula izinga imikhiqizo nemithi izifundo ezimbili esikhathini kusuka 2011 kuya ku-2014.

umbono uchwepheshe

"Ezinye izinkinga ezichazwe iziguli kuhlanganisiwe ezifana izimpawu eziwohlozayo ezifana ukukhanya futhi halo umphumela, kanye amehlo omile," - wathi Dr. Malvina Adelman, umqondisi omunye neminyango FDA futhi co-umbhali amaphepha amabili amasha. Ngokusho kwakhe, kwezinye iziguli imisebenzi yansuku zonke futhi ukushayela ebusuku kakhulu sebehlushwa.

Noma kunjalo, Adelman futhi Starr ukuthi okutholakele musa inselelo imibono mayelana ukuphepha nokusebenza ngempumelelo ukuhlinzwa laser, ngoba izifundo Azidalwanga ukufunda lezi zinkinga.

ucwaningo Ukuqhuba

Kokunye ukuhlola, odokotela ukusabela 240 abamele izisebenzi Navy emva eyodwa futhi izinyanga ezintathu ngemuva kokuhlinzwa. 50% abaphendula abangabantu abasha.

Kokunye ukuhlola, abacwaningi bacubungula izimpendulo 271 empini, kanti isilinganiso seminyaka yobudala laba bantu - iminyaka engu-32. inhlolovo yabo lwenziwe izinyanga eziyisithupha ngemva kokuba sekudlule ngokusebenzisa inqubo ukuhlinzwa laser kwelinye izikhungo ezinhlanu e-United States.

Kufika 46% of the abahlanganyeli ayinazo izimpawu ebonakalayo ngaphambi kokuba uhlinzwe, yabika ukuthi ngemva kokushaywa izinyanga ezintathu ukusebenza kwakukhona okungenani eyodwa uphawu ezibukwayo.

Iziguli libike ukuthi avame eba halo umphumela. Kuya ku 40% iqhaza ngaphandle lo mphumela phambi ukusebenza ngiyitholile emva kwezinyanga ezintathu ke. Ngaphezu kwalokho, kuze kube u-28% walabo ngaphandle izimpawu iso ezomile ngaphambi kokuba sihlinzwe kubika kubo emva kwezinyanga ezintathu.

Le miphumela uhambisane izifundo eyedlule, kusho ososayensi. Noma kunjalo, abantu abangaphezu kuka-90% weziguli wabika yalokho okwanelisayo yini ukuhlinzwa. Futhi labo babe izikhalazo musa njalo bafune usizo.

"Abahlanganyeli okungaphezu kokuphonswe kabili amathuba okuba izimpawu zabo ezibukwayo ngesikhathi inhlolovo kunokukhuluma ngabo odokotela zabo" - Adelman wathi.

Kodwa namanje asikwazi ukusho ukuthi abantu kweminyaka noma ubulili obuthile ukuba usengozini yokuthola lezi zinkinga nasezinkingeni ezilandela ngemva kokuhlinzwa.

UDkt Starr ukuthi lemibuzo ingasetshenziswa ukusiza abacwaningi siyiqonde kangcono indlela ukuhlinzwa laser lihlotshaniswa izinkinga umbono ezithinta izimpilo zabantu.

Izingozi Izinzuzo

"Ngenxa yentuthuko kwezokuhlolwa zanamuhla kwezobuchwepheshe, cishe ayikaze isikhathi esingcono ukuvumelana laser umbono ukulungiswa", - uthe Starr. Waphawula ukuthi ukubuyekeza kwakamuva kwe-4.400 zokwelapha olwenziwa phakathi kuka-2008 no-2015, wathola ukuthi iziguli zithola imiphumela emihle ezibukwayo kunanini ngaphambili.

Nokho, ukuhlinzwa laser asifanele wonke ezigulini eziye kahle umbono. Kukhona ezinye zeziguli eziye ahlale kangcono contact lens noma izibuko, esikhundleni imali laser umbono ukulungiswa. Likhuluma ukubaluleka Ukuhlolwa ngokucophelela, kanye inkhulumomphendvulwano okukhululekile futhi obuthembekile phakathi Isiguli nodokotela mayelana nezinzuzo.
