Ingabe nawe unomuzwa wokuthi umbono wakho uya ngokuya ufiphala njengoba ukhula? Noma ukhathele ukugqoka izibuko? Mhlawumbe udokotela wakho ukutshelile ukuthi udinga ukushintshwa ilensi yakho. Abantu abaningi bayesaba kancane lapho bezwa lokhu, becabanga ukuthi, "Kuzokwenzekani emehlweni akho?" Kodwa empeleni akukwesabisi njengoba ucabanga. Lokhu ukuhlinzwa okuvamile kakhulu okwenziwa ngempumelelo emhlabeni wonke. Namuhla, ake sixoxe ngokuthi kuyini lokhu kuhlinzwa kokushintsha ilensi yamehlo, ukuthi kwenziwa kanjani, nokuthi kwenzekani ngemva kwakho, konke kalula.
Kusho ukuthini ngempela ukushintsha ilensi yeso?
Kalula nje, lokhu kuhilela ukususa ilensi yemvelo engaphakathi kweso lakho bese uyifaka esikhundleni sayo ngelensi yokwenziwa. Kufana nokushintsha ilensi ekhamera.
Ngaphakathi kwamehlo ethu, ngemuva kwe-cornea, kukhona ilensi yemvelo . Lokhu kucacile kakhulu futhi kusobala. Umsebenzi oyinhloko wale lensi ukugxila ukukhanya okuvela ezintweni esizibonayo kuyi-retina engaphakathi kweso, okuhlinzeka ngombono ocacile.
Kodwa ngezinye izikhathi, kungavela izinkinga ngale lensi yemvelo. Ezimweni ezinjalo, udokotela wamehlo ususa ilensi yakho yemvelo bese eyishintsha ngelensi yokwenziwa (Intraocular Lens - IOL) . La malensi okwenziwa enziwe ngezinto ezingenangozi njenge-acrylic noma i-silicone. Agxila ekukhanyeni njengelensi yemvelo futhi akusiza ukuthi ubone umhlaba ngokucacile.
Ngokuvamile kunezinhlobo ezimbili eziyinhloko zokuhlinzwa ezithatha indawo yelensi yaleli liso.
- Ukuhlinzwa Kwe-Cataract
- Ukushintshaniswa Kwelensi Ebonakalayo (Ukushintshaniswa Kwelensi Ebonakalayo)
Ake sibheke lezi ezimbili ngokwehlukana.
Ukuhlinzwa Kwe-Cataract
Lona ukuhlinzwa okuvamile kakhulu esike sezwa ngakho. Njengoba siguga, ngokuvamile ngemva kweminyaka engu-40, ilensi yemvelo ecacile emehlweni ethu iqala ukufiphala kancane kancane ibe njengobisi . Lokhu yilokho esikubiza ngokuthi i-cataract . Kufana nengilazi ecacile egcwala inkungu ngokuhamba kwesikhathi.
Uma le cataract iqala ukwakheka, izinto ziba mnyama, imibala ayibonakali kahle, futhi kuba nzima ukushayela ebusuku. Ngakho-ke uma iqala ukuphazamisa imisebenzi yakho yansuku zonke, udokotela uzoncoma ukuthi ususe le lens enamafu bese ufaka ilensi entsha, ecacile yokwenziwa. Lokhu kubizwa ngokuthi ukuhlinzwa kwe-cataract.
Ukushintshaniswa Kwelensi Ebonakalayo
Lokhu kuhlukile kancane. Kulokhu kuhlinzwa, ilensi yakho yemvelo ayisuswa ngoba inamafu. Lapha, ilensi yakho yemvelo icacile . Kodwa ukuhlinzwa kwenzelwa ukulungisa amaphutha akho okubona , okusho ukuthi awukwazi ukubona kude noma eduze.
Kalula nje, lokhu kuyindlela yokuhlinzwa yokususa izibuko noma ama-contact lens. Lokhu kungaba inketho enhle kulabo abangakwazi ukwenza ukuhlinzwa kokulungisa umbono njenge-LASIK noma i-PRK.
| Isici | Ukuhlinzwa Kwe-Cataract | Ukushintshaniswa Kwelensi Ebonakalayo (Ukushintshaniswa Kwelensi Ebonakalayo) |
|---|---|---|
| Isizathu esiyinhloko sokuhlinzwa | Ukususwa kwelensi yemvelo eye yaba namafu (yaba mhlophe) njengoba ikhula. | Ukunciphisa ukuthembela ezibukweni noma kuma-contact lens (ukulungisa ukubona kude/ukubona eduze). |
| Isimo selensi yemvelo ngaphambi kokuhlinzwa | Kufiphele, kufana nobisi. | Kusobala, kodwa kukhona iphutha elibonakalayo. |
Yiziphi izinhlobo zamalensi angaphakathi kweso (ama-IOL)?
Manje ungase uzibuze, "Ingabe ilensi iyafana kuwo wonke umuntu?" Cha, akunjalo. Kunezinhlobo eziningana zamalensi angaphakathi kweso (ama-IOL) ongakhetha kuzo kuye ngezidingo zakho, isimo samehlo, kanye nendlela yokuphila. Uhlobo ngalunye lunezinzuzo nezinkinga zalo. Kunezinhlobo ezintathu eziyinhloko zamalensi.
1. Amalensi e-Monofocal: Lawa uhlobo lwamalensi oluvame ukusetshenziswa kakhulu. Lawa malensi angakunikeza umbono ocacile ebangeni elilodwa kuphela. Odokotela bavame ukulungisa lawa malensi ukuze ukwazi ukubona kahle ebangeni elilodwa . Lokhu kusho ukuthi ungabona izinto ebangeni elikude (njengokubuka i-TV noma ukushayela) ngokucacile ngaphandle kwezibuko, kodwa kuzodingeka ugqoke izibuko ukuze usebenze eduze (njengokufunda incwadi noma ukusebenzisa ifoni yakho) .
2. Amalensi amaningi: Lawa afana nezibuko ezimbili. Lawa malensi anikeza umbono webanga kanye nebanga eliseduze .Zinikeza umbono ocacile. Ngakho-ke, ezimweni eziningi, ungakhululeka ngokuphelele ekusebenziseni izibuko uma ugqoka ilensi enjengale. Kodwa-ke, lezi zibiza kakhulu kunelensi ye-monofocal. Abanye abantu bangase babe nemiphumela emibi njengokukhanya okuzungeze izibani ebusuku.
3. Amalensi e-Toric: Lawa aklanyelwe ngokukhethekile abantu abanenkinga yokubona ebizwa ngokuthi i-astigmatism . I-Astigmatism yisimo lapho i-cornea yeso ingeyona indilinga ngokuphelele, kodwa ide kakhulu, njengebhola le-rugby. Lokhu kungabangela ukubona okufiphele. Ngakho-ke uma une-cataracts kanye ne-astigmatism, ukuthola ilensi ye-toric kungakusiza ukulungisa zombili izinkinga ngesikhathi esisodwa.
Kungcono ukuxoxa ngohlobo lwelensi olufanele wena nodokotela wakho ohlinza amehlo. Uzohlola amehlo akho, axoxe ngezidingo zakho, futhi akunikeze ikhambi elingcono kakhulu.
Ngingazi kanjani ukuthi lokhu kuhlinzwa kulungile kimi?
Kunezici eziningana ezihilela ekunqumeni ukuthi lokhu kuhlinzwa kukulungele yini. Akudingeki wenze lesi sinqumo wedwa, udokotela wakho uzozicabangela zonke lezi zinto futhi akunikeze iseluleko.
- Impilo yamehlo akho: Kubalulekile ukwazi ukuthi unezinye izifo zamehlo (njenge-glaucoma).
- Ukucaca kombono wakho: Ukuthi umbono wakho uwohloke kangakanani nokuthi uthinta kanjani impilo yakho yansuku zonke.
- Impilo yakho iyonke: Kungakhathaliseki ukuthi unezinye izifo, njengesifo sikashukela noma umfutho wegazi ophakeme, nokuthi ziyalawuleka yini.
- iminyaka yakho.
Ngemva kokucabangela konke lokhu, udokotela uzokuchazela izinzuzo zokuhlinzwa kanye nezingozi ezincane ezingaba khona.
Kwenziwa kanjani ukuhlinzwa? Ingabe kufanele ngesabe?
Yilapho abantu abaningi besaba khona. Kodwa asikho isizathu sokwesaba. Lokhu kuhlinzwa kuyashesha kakhulu, ngokuvamile kuqedwa ngemizuzu eyi-15 kuya kwengama-30 .
Ngeke uzwe ubuhlungu ngesikhathi sokuhlinzwa. Lokhu kungenxa yokuthi amaconsi amehlo azofakwa emehlweni akho ngaphambi kokuba kuqale ukuhlinzwa. Uzophinde unikezwe umuthi wokunciphisa ukukhathazeka nokucindezeleka kwakho. Lokhu kuzokusiza uphumule.
Ngemva kokuhlinzwa, ithimba lezokwelapha lizokuqapha amahora ambalwa bese likuthumela ekhaya. Kodwa khumbula, ngeke ukwazi ukushayela ngalolo suku . Ngakho-ke kubalulekile ukuba nomuntu ozokuthatha akuyise ekhaya. Kuvamile ukuthi umbono wakho ufiphale kancane ngemva kokuhlinzwa.
Lokhu kuyindlela yokuhlinzwa engadingi ukungenelela okuningi . Udokotela wenza konke lokhu kuhlinzwa ngokusika okuncane kakhulu esweni . Ukusikwa kuncane kakhulu kangangokuthi kuyaphola ngokwako .Awudingi ngisho nokuthungwa.
Kwenzekani ngesikhathi sokuhlinzwa isinyathelo ngesinyathelo
Le nqubo ibizwa ngokuthi i-phacoemulsification . Nakuba igama lingase lizwakale liyinkimbinkimbi kancane, okunye kulula kakhulu.
1. Okokuqala, udokotela ufaka ithuluzi elincane esweni ngalowo msibo omncane.
2. Bese, usebenzisa imisebe ye-laser noma amaza omsindo aphindaphindwayo (i-ultrasound), ilensi yakho yemvelo enamafu iyaqhekeka ibe yizicucu ezincane kakhulu bese incibilika.
3. Okulandelayo, izingcezu zelensi ezincibilikisiwe zikhishwa ngokucophelela ngedivayisi efana nomshini wokuhlanza i-vacuum.
4. Manje indawo lapho ilensi yemvelo yayikhona ayinalutho. Kuleyo ndawo engenalutho, ngaleyo ndlela encane efanayo, ilensi yokwenziwa egoqiwe `(IOL)` ifakwa. Uma isingaphakathi kweso, iyakhula ngokuzenzakalelayo futhi izinze endaweni yayo.
Yilokho kuphela. Lena inqubo efanayo eyenzeka ekuhlinzeni i-cataract kanye nokuhlinzwa kokulungisa umbono. Umehluko kuphela ukuthi ekuhlinzeni i-cataract, ilensi enamafu iyasuswa, kanti kwenye, ilensi ecacile iyasuswa.
Kuthatha isikhathi esingakanani ukululama ngemva kokuhlinzwa?
Kungathatha amasonto afika kwayisishiyagalombili ukuthi iso lakho liphole ngokuphelele. Kodwa lokho akusho ukuthi kufanele uhlale embhedeni amasonto ayisishiyagalombili. Ungaqhubeka nemisebenzi yakho eminingi evamile zingakapheli izinsuku ezimbalwa zokuhlinzwa.
Udokotela wakho uzokunika izinhlobo eziningana zamaconsi amehlo ongazisebenzisa. Kubaluleke kakhulu ukuwafaka emehlweni akho njengoba kuyalelwe, ngesikhathi esifanele. Kufanele futhi uqaphele ukuthi ungangenisi amanzi noma uthuli emehlweni akho. Akukuhle ukuhlikihla amehlo akho. Udokotela wakho uzokunikeza imiyalelo eqondile yokuthi ungashayela nini noma wenze umsebenzi onzima futhi.
Kuphephile kangakanani lokhu kuhlinzwa? Ziyini izingozi?
Njenganoma yikuphi ukuhlinzwa, kunezingozi ezincane kakhulu. Kodwa empeleni, ukuhlinzwa kwe-cataract kuyinqubo ephephile kakhulu . Ucwaningo luthole ukuthi abantu abangu-98% abahlinzwa i-cataract ababi nezinkinga ezinkulu .
Kunezinkinga ezimbalwa ezingavamile kakhulu ezingavela, eziningi zazo ezingalashwa kalula futhi zelashwe odokotela.
- Ukopha ngaphakathi kweso
- Ukuba nokutheleleka
- Ukuvuvukala (ukuvuvukala, ukubomvu)
- I-Glaucoma (ukwanda komfutho wamehlo)
- I-Posterior Capsular Opacification - Lokhu kubizwa nangokuthi "i-secondary cataract". Lokhu kungalungiswa ngemizuzu embalwa ngokwelashwa nge-laser.
- Ukuhlukaniswa kwe-Retinal
- Ukulahlekelwa umbono (lokhu akuvamile kakhulu )
Kubalulekile ukukhuluma nodokotela wakho ngengozi yakho ngokusekelwe esimweni samehlo akho kanye nezinye izimo zezokwelapha.
Le lensi entsha yokuxhumana izohlala isikhathi esingakanani?
Nazi izindaba ezinhle! Le lensi yokwenziwa (IOL) oyifakile esweni lakho yenzelwe ukuhlala impilo yakho yonke . Ihlala njalo. Akudingeki ukuthi uyishintshe kaninginingi.
Kodwa-ke, ezimweni ezingavamile, abanye abantu kungadingeka bashintshe amalensi abo. Isibonelo:
- Uma kukhona inkinga ngelensi efakiwe.
- Uma ungakwazi ukubekezelela imiphumela emibi yezinhlobo ezithile zamalensi, njengokukhanya okukhanyayo.
- Uma udinga ilensi enamandla ahlukile ukuze wenze umbono wakho ucace kakhudlwana.
Kubiza malini lokhu?
Izindleko zalokhu kuhlinzwa ziyahlukahluka kuye ngezici eziningana.
- Isizathu sokuhlinzwa: Uma uhlinzwa ngenxa ye-cataracts, izinhlelo eziningi zomshuwalense wezempilo zizoyikhokhela. Kodwa-ke, uma kwenziwa ukuze kulungiswe umbono wakho (i-Refractive Lens Exchange), ezinye izinhlelo zomshuwalense zingase zingakukhokheli.
- Uhlobo lwelensi (IOL) olukhethayo: Umshwalense uvame ukumboza kuphela izindleko zamalensi ayisisekelo e-monofocal. Uma ukhetha ilensi "ephezulu", njenge-multifocal noma i-toric, kungase kudingeke ukhokhe imali eyengeziwe ngayo.
Ngakho-ke, kubaluleke kakhulu ukukhuluma nodokotela wakho kanye nenkampani yakho yomshuwalense mayelana nezindleko ezihilelekile ngaphambi kokuhlela ukuhlinzwa kwakho.
Ukuhlinzwa kwe-cataract kuyinqubo ephumelela kakhulu engashintsha impilo yakho, icacise umbono wakho, futhi ikusize ulahle izibuko. Akukho okufanele ukwesabe. Into ebaluleke kakhulu ukuxoxa ngayo yonke imibuzo yakho nokwesaba kwakho nodokotela wakho, ukwaziswa ngakho konke, futhi ubhekane nokuhlinzwa ngengqondo ezolile.
Umlayezo Wokuya Nawe Ekhaya
- Ukuhlinzwa kwe-cataract kungenye yezindlela ezivame kakhulu, eziphephile, nezisheshayo emhlabeni. Ungesabi ngakho.
- Lokhu kwenziwa kakhulu ukususa ama-cataract (ilensi efiphele) noma ukulungisa ukukhubazeka kokubona (ukubona kude/ukubona eduze).
- Kunezinhlobo eziningana zamalensi angaphakathi kweso (ama-IOL) afakwa esweni lakho. Khuluma nodokotela wakho mayelana nokuthi iyiphi ilensi engcono kakhulu ezidingweni zakho.
- Nakuba ukululama ngemva kokuhlinzwa kushesha, kubaluleke kakhulu ukulandela imiyalelo yezokwelapha, ikakhulukazi ukusetshenziswa kwamaconsi amehlo, ngendlela efanele.
- Izinkinga azivamile, kodwa kubalulekile ukubuza udokotela wakho ngezingozi ezingaba khona.
- Cacisa ngezindleko zokuhlinzwa, umshwalense, kanye namanani ezinhlobo zamalensi ngaphambi kokuhlinzwa.
