Ese koko tuzi ibijyanye n'indorerwamo zo mu maso (IOLs)?

Wigeze wumva iby’indwara ya katarakte? Cyangwa wenda ushaka uburyo bwo kubona isi neza udafite indorerwamo. Muganga wawe w’amaso ashobora kuba yarakubwiye ibijyanye na 'Indorerwamo zo mu maso' cyangwa 'IOL'. Rero, uyu munsi turaganira mu buryo bworoshye kandi bw’inshuti ku bijyanye n’izi 'IOL', abazikeneye, ubwoko bwazo, uburyo bwo guhitamo izidukwiriye, n’ingorane zishobora guterwa na zo.

IOLs ni iki? Kuki ari ingenzi kuri twe?

Mu magambo make, `IOL` cyangwa `Intraocular Lens` ni lens igaragara neza cyane ishyirwa mu jisho ryawe, igasimbuza lens yawe isanzwe. Tekereza nawe, lens isanzwe iri mu jisho ryacu imeze nk'`lens` ya kamera. Uko igihe kigenda gihita, iyi lens ishobora kuba iy'ibicu, ari byo twita `cataract` . Icyo gihe ni bwo `IOL` ishyirwamo kugira ngo ikureho iyo lens isanzwe y'ibicu, iguhe kongera kubona neza. Nkuko ubikora ku ndorerwamo zawe cyangwa `contact lens`, izi lens za `IOL` zishobora gukosora ibibazo bitandukanye byo kureba. Urugero:

• Myopia (kureba hafi): Kubona ibintu hafi neza, ariko ibintu biri kure bisa n'aho bitagaragara neza.
• Kureba hafi (Hyperopia cyangwa kureba kure): Kubona ibintu biri kure neza, ariko kubona ibintu biri hafi, cyane cyane iyo ureba igitabo cyangwa ikinyamakuru, ntibisobanutse neza.
• Presbyopia (kureba hafi) uko tugenda dusaza: Abantu benshi bagorwa no gusoma inyandiko nto nyuma y'imyaka 40.
• Astigmatisme: Ibi biterwa n'impinduka mu miterere y'ijisho, bigatuma urumuri rukwirakwira aho kwibanda ahantu hamwe, bigatera kutabona neza.

Izi lenzi za `IOL` zishyirwa mu jisho burundu , bivuze ko ziguma mu mwanya wazo ubuzima bwose nyuma yo kubagwa. Zishobora kunoza cyane icyerekezo cyawe no kugabanya cyane kwishingikiriza ku ndorerwamo mu mirimo ya buri munsi. Izi lenzi za `IOL` zikunze gushyirwa mu jisho mu gihe cyo kubagwa kwa katarakte .

Ni nde ukeneye izi lenzi za IOL mu by'ukuri?

Ushobora kungukirwa na IOLs niba ufite kimwe muri ibi bibazo:

• Niba ufite ishaza ry'amaso kandi ukaba utabona neza kubera zo: Mu by'ukuri, abantu benshi babagwa ishaza ry'amaso hafi ya bose baba bakeneye ishaza rya IOL kugira ngo bongere kubona neza.
• Niba ufite izindi makosa yo gukosora amaso, ariko utari umukandida mwiza wo kubagwa izindi ndwara zo gukosora amaso nka LASIK :Hari igihe, bitewe n'imiterere imwe n'imwe y'ijisho ry'umuyoboro w'amaraso, 'LASIK' ntishoboka. Ku bantu nk'abo, lenseri za 'IOL' zishobora kuba igisubizo cyiza.

Ni ubuhe bwoko bwa lenses za IOL zihari? Reka turebe buri imwe.

Hari ubwoko butandukanye bwa IOL. Buri bwoko bufite ibyiza n'ibibi byabwo. Ingaruka mbi nyamukuru z'ubwoko bumwe na bumwe bwa lenti ni uko ugikeneye indorerwamo mu mirimo imwe n'imwe (urugero, gusoma igitabo). Nubwo ubundi bwoko bwa IOL bushobora kugabanya gukenera indorerwamo, bushobora gutera ingaruka mbi, nko kurabagirana hafi y'amatara y'imbere mu gihe utwaye imodoka nijoro. Hano hari ubwoko bumwe na bumwe bw'ingenzi bwa IOL. Ni byiza kuvugana n'umuganga w'amaso kugira ngo agufashe guhitamo ubwoko bwa lenti ikubereye. Ashobora kugufasha guhitamo lenti ikubereye ibyo ukeneye mu kureba, ubuzima bwawe, n'ibyo ukunda.

1. Indorerwamo z'ijisho rimwe (monofocal lenses)

Ubu ni bwo bwoko bwa lens abantu benshi bahitamo. Lens za `Monofocal` zifite imbaraga imwe gusa zo kwibandaho . Ibi bivuze ko izi lens zikora kimwe cya gatatu cy'uburyo ubona kure, kureba hagati (urugero, iyo ureba mudasobwa), cyangwa kureba hafi. Abantu benshi babona izi lens za `Monofocal` zigenewe kureba kure. Ibi bifasha cyane mu mirimo nko gutwara imodoka. Ariko, niba ibyo bibaye, uzakenera gukoresha indorerwamo mu mirimo yo kureba hafi, nko gusoma igitabo cyangwa kureba ikinyamakuru. Ku bantu bamwe bashaka kugabanya kwishingikiriza ku ndorerwamo, lens za ` Monovision` zigenewe `Monofocal IOL` zishobora kuba amahitamo meza. Ubusanzwe, lens za `Monofocal` zishyirwa ku maso yombi zihindurwa ku ntera imwe (urugero, kureba kure). Ariko muri `Monovision`, lens iri mu jisho rimwe ikorwa n'imbaraga imwe naho lens iri mu jisho rindi ikorwa n'imbaraga zitandukanye . Urugero, ushobora kugira lens igenewe kureba kure mu jisho ryawe ry'iburyo n'lens igenewe kureba hafi mu jisho ryawe ry'ibumoso. Muri 'Monovision', amaso yawe yombi akorana kugira ngo agufashe kubona ibintu biri kure n'ibiri hafi. Ariko, ibi bifata igihe kugira ngo ubimenyere. Hari abantu bashobora kutamenyera 'Monovision' na gato. Kubwibyo, mbere yo guhitamo 'Monovision IOL', muganga wawe ashobora kugusaba kugerageza 'Monovision contact lenses' mu gihe cy'ibyumweru bike. Hanyuma ushobora kureba niba ubu buryo bukubereye.

2. Indorerwamo za multifocal

Lenseri za `Multifocal` zishobora kunoza kureba kwawe kwa hafi no kure , kandi zikagabanya gukenera indorerwamo. Bitandukanye na lenseri za `Monofocal`, lenseri za `Multifocal` zifite ahantu henshi hagaragara.Yego. Ubwonko bwawe bumenyera utu duce hanyuma bugahitamo imbaraga zikenewe mu gikorwa icyo ari cyo cyose (urugero, gutwara imodoka cyangwa gusoma igitabo). Bishobora gufata igihe kugira ngo umenyere izi lens. Ariko uko igihe kigenda gihita, ugomba kuba ushobora kugabanya kwishingikiriza ku ndorerwamo zo gusoma. Hari abantu bashobora no kudakenera indorerwamo na gato. Imbogamizi imwe y'indorerwamo za 'multifocal' ni uko ushobora kubona 'impeta' cyangwa imirasire y'urumuri ('halos') hafi y'amatara rimwe na rimwe, nko mu gihe utwaye imodoka nijoro.

3. Indorerwamo za "extended depth-of-focus" (EDOF)

Bitandukanye n'ama-lense ya 'multifocal', ama-lense ya 'EDOF' afite ahantu hamwe hirengeye ho kwibanda . Ibi bikongera urwego rwawe rwo kureba neza n'ubwiyongere bw'ubwiyongere bw'ibyibandwaho. Aya ma-lense aguha kureba neza kure , ndetse akananoza kureba hagati (ku mirimo nko gukoresha mudasobwa). Ariko, ushobora gukenera gukoresha indorerwamo mu mirimo yo hafi, nko gusoma igitabo cyangwa ikinyamakuru.

4. Indorerwamo zo kwakira abantu

Izi lenzi ni nk'indorerwamo karemano mu maso yacu. Ibi bivuze ko iyo urebye ibintu biri hafi cyangwa kure, izi lenzi zishobora guhindura imiterere yazo . Ubu ni ubundi buryo bwiza bwo kugabanya kwishingikiriza ku ndorerwamo. Ariko, niba umara igihe kinini usoma igitabo cyangwa niba ugomba 'kwibanda' ku kintu kiri hafi, ushobora gusanga byoroshye gukoresha indorerwamo.

5. Indorerwamo za Toric

Indorerwamo za Toric zifasha abantu bafite astigmatism . Izi ndorerwamo zinoza uburyo urumuri rugwa kuri retina yawe, ziguha ubushobozi bwo kureba neza kandi neza. Indorerwamo za Toric ziboneka mu buryo bwa Monofocal, Multifocal, EDOF cyangwa Accommodative. Zinoza ubwiza bw'amaso. Indorerwamo za Toric zifasha kandi kugabanya urumuri n'urumuri, ari byo bibazo bikunze kugaragara ku bantu bafite astigmatism.

6. Indorerwamo zoroheje (LALs)

Indorerwamo z'urumuri (LALs) zitandukanye n'izindi nzira za IOL kuko nyuma yo kubagwa indorerwamo z'ijisho , umuganga w'amaso azakosora imbaraga zo gukosora izi ndorerwamo. Ibi bikorwa binyuze mu buryo butandukanye bwo kuvura urumuri rwa UV, buri hagati y'iminsi mike. Ubu buryo buzahuza imiti ya lensi yawe n'amaso yawe uko bishoboka kose, kandi buzagukorerwa by'umwihariko. Iyi ni lensi ikiri monofocal, bityo ushobora gukenera indorerwamo zo gusoma cyangwa gutwara.

7. Indorerwamo za Phakic

Indorerwamo za Phakic zikunze gushyirwa mu rubyiruko, mu gihe zigerageza kubungabunga indorerwamo zabo karemano z'abantu.Zikoreshwa mu gukosora ikibazo cyo kutabona neza, cyane cyane ku bantu badakwiriye kubagwa hakoreshejwe laser. Ibi bifasha mu kubungabunga ubushobozi bwawe bwo kwibanda no kwakira neza. Izi lens zishobora guha urubyiruko ubushobozi bwo kubona neza igihe kirekire, nubwo byaba ngombwa ko zikurwamo kugira ngo zibagwe cataract mu gihe kizaza.

Nigute nahitamo lensi ya IOL ikwiye?

Muganga w'amaso yawe azagufatira umwanzuro niba wakungukirwa no kubagwa cataract cyangwa niba wujuje ibisabwa kugira ngo ubagwe refractive lenses. Azagusobanurira amahitamo yawe kandi agufashe guhitamo IOL ikubereye. Azagukorera kandi isuzuma ryuzuye ry'amaso kugira ngo arebe uko amaso yawe ahagaze n'uko ahagaze. Azakora kandi ibizamini byinshi byoroshye kandi bitababaza kugira ngo apime ingano n'imiterere y'ijisho ryawe.

Mbere yo kuvugana na muganga w'amaso, ni byiza gutekereza ku byo ushyira imbere ukoresheje indorerwamo za IOL, n'ibintu bitari ngombwa kuri wowe.

Byagufasha kwibaza ibi bibazo:

• Ese rimwe na rimwe birangora kwambara indorerwamo ? Niba ari byo, ni kangahe kandi ni iyihe mpamvu? (urugero: nijoro gusa? iyo nsoma ibitabo gusa?)
• Ni ubuhe bwoko bw'icyerekezo akazi kanjye/umwuga wanjye gasaba? Ese mfite ikibazo cyo kwambara indorerwamo kuri aka kazi? (Tekereza niba ukorana na mudasobwa igihe kirekire.)
• Ese nkunda gutwara imodoka nijoro? Niba ari byo, ese nshobora kumenyera kubona urumuri n'urumuri bikikije amatara iyo ntwaye imodoka?
• Ni ibihe bikorwa nkunda cyane? Ni mu rugero rungana iki niteguye kwishingikiriza ku ndorerwamo muri ibi bikorwa? (Urugero, niba ukunda kudoda, kureba hafi ni ingenzi cyane.)
• Ingengo y'imari yanjye yo kubaga ni iyihe?

Nubwo gahunda nyinshi z'ubwishingizi zitanga ama-lenses ya 'Monofocal', ushobora kwishyura mu mufuka wawe ku zindi. Rero, menya neza ibiciro nyabyo by'amahitamo atandukanye ya 'IOL' mbere yo gufata icyemezo cya nyuma.

Ni ibihe bibazo n'ingorane bishobora kubaho mu gihe cyo gutera IOL?

Ingorane nyinshi za IOL ntizikunze kubaho , ariko ni byiza kubimenya. Dore zimwe muri zo:

• Ubwiyongere bw'inyuma y'inyuma: Ibi bikunze kwitwa cataract ya kabiri.Ibi bibaho iyo urwego rw'ibikoresho ruvutse inyuma y'indorerwamo yashyizwemo, amezi cyangwa imyaka nyuma yo kubagwa. Iyi ni inzira isanzwe nyuma yo kubagwa, kandi ni ikintu buri wese ashobora kwitega uko igihe kigenda. Kuvura ibi ni byihuse kandi byoroshye, akenshi bikorerwa mu biro hakoreshejwe "laser".
• Gucika kwa IOL: Iki ni cyo gihe IOL yawe iva mu mwanya wayo usanzwe. Uba uri mu kaga gakomeye niba ufite indwara zimwe na zimwe z'amaso , nka pseudoexfoliation syndrome, cyangwa niba waragize imvune mu jisho cyangwa warabanje kubagwa ijisho . Hari indwara zimwe na zimwe zo mu ngirabuzimafatizo , nka Ehlers-Danlos syndrome na Marfan syndrome, zishobora kongera ibyago byawe. Hari igihe, kubagwa bishobora kuba ngombwa kugira ngo uhindure cyangwa usimbuze IOL.
• Uveitis-glaucoma-hyphema (UGH): UGH syndrome ibaho iyo IOL irakaje ijisho ryawe n'ibindi bice by'ijisho ryawe. Ibi bishobora gutera kubyimba imbere, kwiyongera k'umuvuduko w'amaso, n'ibindi bimenyetso. Kimwe no kwangirika kwa IOL, kubagwa bishobora kuba ngombwa kugira ngo IOL ihindurwe cyangwa ishyirwemo indi nshya. Iyi ni ingorane idasanzwe abantu benshi badahura nayo mu gihe cyo kubagwa bisanzwe.
• IOL opacification: Iki ni cyo gihe lenzi yawe ya IOL iba irimo ibicu. Ubushobozi bwo kureba bushobora kugabanuka, kandi ushobora kubona urumuri rukikije amatara. Ubu buryo ni ukubaga kugira ngo ushyiremo IOL nshya. Ibi ntibikunze kubaho muri IOL zigezweho.
• Guhinduka mu buryo butunguranye mu maso (`Refractive surprise`): `Refractive surprise` ni igihe amaso yawe adakomeye nk'uko wowe na muganga wawe w'amaso mwari mwiteze nyuma yo guterwa 'IOL'. Muganga wawe w'amaso azaguha ibisubizo bitandukanye. Ushobora kwemera ko amaso yawe ari uko ameze nta kindi ukora. Cyangwa ushobora kwambara indorerwamo, kubagwa 'laser' mu buryo bwo gukosora amaso nka `LASIK` cyangwa `PRK`, cyangwa kubagwa 'IOL` mu buryo bwo guhinduranya lenzi.

Mbere yo gufata icyemezo cyo gutera IOLs, ganira na muganga w'amaso ku bibazo bishobora kubaho ndetse n'urwego rw'ibyago byawe. Azakubwira icyo wakwitega hashingiwe ku mateka y'ubuzima bwawe, ubuzima bw'amaso, n'ibindi bintu. Baza kandi ingaruka zikunze kugaragara zijyanye no kubagwa cataract cyangwa kubagwa indorerwamo z'amaso. Ni ngombwa kugira amakuru yose ukeneye kugira ngo ufate icyemezo gikwiye.

Amaherezo, ibintu byo kwibuka

Indorerwamo zo mu maso (IOLs) ni ikoranabuhanga ryiza cyane rishobora gufasha abantu benshi kubona isi neza kurusha mbere hose. Uko ikoranabuhanga ritera imbere, IOLs zitanga inyungu nyinshi, kandi nta mbogamizi nyinshi zifite. Iyo uhisemo IOL yawe, bishobora kuba ingirakamaro gukora urutonde rw'ibyo ushyira imbere (ibintu bikubereye cyane). Nanone, andika ibintu "byiza kugira, ariko bitari ngombwa." Sangiza aya makuru muganga wawe w'amaso. Hanyuma, hamwe, mushobora gufata icyemezo cyiza. Wibuke ko aya ari amaso yawe, kureba kwawe. Rero ni uburenganzira bwawe guhitamo ikikubereye.
