Luyini Uvivinyo Olujwayelekile Lamehlo?

Ukuhlolwa okujwayelekile kwamehlo kuwuchungechunge olunzulu lokuhlolwa okwenziwe ngudokotela wamehlo. Udokotela wamehlo ungudokotela ogxile kwezempilo yamehlo. Lezi zivivinyo zihlola umbono wakho kanye nempilo yamehlo akho.

Kungani Ngidinga Ukuhlolwa Kwamehlo?

Ngokusho komtholampilo iMayo, izingane kufanele zivivinywe okokuqala ezineminyaka ephakathi kwemithathu kuya kwemihlanu. Izingane kufanele futhi zihlolwe amehlo ngaphambi kokuba ziqale ibanga lokuqala futhi kufanele ziqhubeke nokuhlolwa iso njalo ngonyaka kuya kwemibili. Abantu abadala abangenankinga yokubona kufanele amehlo abo ahlolwe njalo eminyakeni emihlanu kuya kweyishumi. Kusukela eneminyaka engama-40, abantu abadala kufanele bahlolwe amehlo njalo eminyakeni emibili kuya kwemine. Ngemuva kweminyaka yobudala engama-65, thola ukuhlolwa minyaka yonke (noma ngaphezulu uma unezinkinga ngamehlo noma umbono wakho).

Labo abanenkinga yamehlo kufanele babonane nodokotela wabo mayelana nokuvama kwezivivinyo.

Ngisilungiselela Kanjani Isivivinyo Samehlo?

Akukho ukulungiselela okukhethekile okudingekayo ngaphambi kokuhlolwa. Ngemuva kokuhlolwa, ungadinga umuntu ozokushayela ekhaya uma udokotela wakho evule amehlo akho futhi umbono wakho ungakabuyeli kokujwayelekile. Letha izibuko zelanga esivivinyweni sakho; ngemuva kokuhlanza, amehlo akho azokhanya kakhulu. Uma ungenazo izibuko zelanga, ihhovisi likadokotela lizokunikeza okuthile ukuvikela amehlo akho.

Kwenzekani Ngesikhathi Sokuhlolwa Kwamehlo?

Udokotela wakho uzothatha umlando wamehlo ophelele kufaka nezinkinga zakho zokubona, noma yiziphi izindlela zokulungisa onazo (isb., Izibuko noma amalensi wokuxhumana), impilo yakho yonke, umlando womndeni, kanye nemithi yamanje.

Bazosebenzisa ukuhlolwa kwe-refraction ukuhlola umbono wakho. Ukuhlolwa kokukhipha lapho ubheka khona idivayisi enamalensi ahlukene eshadini leso iso elingamamitha angu-20 kude ukusiza ukuthola ubunzima bokubona.

Bazophinde bavule amehlo akho ngamaconsi wamehlo ukwenza abafundi babe bakhulu. Lokhu kusiza udokotela wakho ukuthi abheke ngemuva kweso. Ezinye izingxenye zesivivinyo zingabandakanya ukuhlola umbono wakho wezinhlangothi ezintathu (stereopsis), ukuhlola umbono wakho wangaphandle ukubona ukuthi ubona kahle kangakanani ngaphandle kokugxila kwakho ngqo, nokuhlola impilo yemisipha yakho yamehlo.

Ezinye izivivinyo zifaka:

• ukuhlolwa kwabafundi bakho ngesibani ukubona ukuthi baphendula kahle yini
• ukuhlolwa kwe-retina yakho ngelensi yokukhulisa ekhanyisiwe ukuze ubone impilo yemithambo yegazi kanye nomthambo wakho we-optic
• isivivinyo sesibani esisikiwe, esisebenzisa enye into ekhanyisayo ukukhanyisa ijwabu leso, i-cornea, i-conjunctiva (ulwelwesi oluncane olumboze abamhlophe bamehlo), kanye ne-iris
• i-tonometry, ukuhlolwa kwe-glaucoma lapho kuqhuma khona umoya ongenabuhlungu esweni lakho ukukala ingcindezi yoketshezi olusesweni lakho
• ukuvivinywa kombala, lapho ubheka khona imibuthano yamachashazi amibalabala enezinombolo, izimpawu, noma ubujamo kuwo

Isho Ukuthini Imiphumela?

Imiphumela ejwayelekile isho ukuthi udokotela wakho akatholanga lutho olungavamile ngesikhathi sokuhlolwa kwakho. Imiphumela ejwayelekile ikhombisa ukuthi:

• ube nombono ka-20/20 (ojwayelekile)
• ingahlukanisa imibala
• abanazo izimpawu ze-glaucoma
• ayinakho okunye okungajwayelekile ngenzwa ye-optic, i-retina, nemisipha yamehlo
• azinazo ezinye izimpawu zesifo noma iso

Imiphumela engajwayelekile isho ukuthi udokotela wakho uthole inkinga noma isimo esingadinga ukwelashwa, kufaka phakathi:

• ukungaboni kahle okudinga izibuko zokulungisa noma amalensi wokuxhumana
• i-astigmatism, isimo esidala ukungaboni kahle ngenxa yokuma kwe-cornea
• umgudu wezinyembezi ovinjiwe, ukuvinjelwa kohlelo okususa izinyembezi futhi kubangele ukudabuka ngokweqile)
• iso elvilaphayo, lapho ubuchopho namehlo kungasebenzi ndawonye (okuvamile ezinganeni)
• i-strabismus, lapho amehlo angahambisani kahle (ajwayelekile ezinganeni)
• ukutheleleka
• ukuhlukumezeka

Isivivinyo sakho singaveza nezimo ezibucayi kakhulu. Lokhu kungafaka

• Ukwehla kwe-macular okuhlobene nobudala (i-ARMD). Lesi yisimo esibi esilimaza i-retina, okwenza kube nzima ukubona imininingwane.
• I-cataract, noma ukufiphazwa kwelensi ngeminyaka ethinta umbono, nakho kuyisimo esivamile.

Udokotela wakho angathola futhi i-corneal abrasion (ukuqala ku-cornea okungadala ukungaboni kahle noma ukungakhululeki), izinzwa ezilimele noma imithambo yegazi, ukulimala okuhlobene nesifo sikashukela (i-retinopathy yesifo sikashukela), noma i-glaucoma.
