Lens Toric - ukunxiba njani? Lens astigmatism

lens Toric - uhlobo olulodwa amanqaku ezamehlo yenzelwe ekulungiseni umbono abantu abanengxaki astigmatism. ezahlukeneyo Ezo lula kwaye aluncedo asetyenziswayo kunye nabo kwiqela lokulungileyo kuthelekiswa nemithi.

iimpawu astigmatism

Phakathi zonke izifo iliso indawo ekhethekileyo unikwa astigmatism. Le yingxaki ephathelene onesiphene le inwebu okanye lens, nto leyo ekhokelela ukuba umntu ulahlekelwa ndikho, nombono ocacileyo. Amaninzi, astigmatism kubonakala kwangoko ebomini yaye inkqubela kunye ukubona okanye ezikude.

Amanqaku okanye amanqaku zemveli nzima yaye soft enombala ukuze ulungise kancinane inkqubo phambi iintlobo eziziziqalelo ngezifo, kodwa ke imilo ungqukuva lens zingachaphazela le ngxaki, ukuba umntu onesifo sifo ngezinga eliphezulu. Loo olukhetho kunceda kuphela xa ukubona okanye ezikude. Isisombululo kule ngxaki zezi toric lenses. Indlela ukunxiba ngathi iinketho uxelele iingcali, ekubeni nezikhundla zabo phezu inwebu ixhomekeke kwindlela aya kubona ngokucacileyo indoda.

ukuba nombono

Toric lens - ntoni na? ezahlukeneyo abanjalo phantse iimpawu efanayo imveliso eqhelekileyo enombala, kwaye zenziwe ngayo izinto ezifanayo. Umahluko yindlela amile lens ngokwayo, yaye isikhundla kufuneka kungene kwi inwebu ukwenzela ukunika nezo ziphumo zinqwenelekayo. Kanye ngenxa yale nto likuvumela ukuba ulungise astigmatism kwinqanaba eliphezulu xa kuthelekiswa kulimo ungqukuva izixhobo ezisebenzisa kunye iindondo.

Kukho lens nzima yaye soft toric. Ngokophindayo nabo kuxhomekeke kanye kule hlobo. lens Soft bakhululekile kakhulu ekukhetheni, ukusetyenziswa kunye nokhathalelo, ngoko abantu abaninzi bakhetha kubo. Ngaphandle koku, iimveliso enombala technology lemveliso ngqwabalala kwiminyaka yakutshanje itshintshiwe, nto leyo iba nefuthe elihle nakwizinga intuthuzelo. Ukongeza, banalo ixesha elide inkonzo, yaye oko ngokugqibeleleyo eyifaneleyo uqeqesho astigmatism, ngenxa yokuba ixesha elide kunye nokugcinwa nokumila inwebu. Ukhetho kuxhomekeke esizithandayo, ubungqongqo iingxaki mbono, kwakunye lomntu ngamnye.

iimpawu

Kutshanje, qhagamshelana technology lens lemveliso toric itshintshile. Lubonakala kuphela kwinqanaba izinto, iimpawu kunye nokulungiswa care, kunye noyilo. Ukuza kuthi ga ngoku, iinkampani ezizodwa ezifundisa umbala lens toric, leyo, ukongeza kumsebenzi wayo enombala, kananjalo zibe nefuthe izithambiso.

lens Toric zenziwa hydrogel kunye abicah hydrogel, xa kufikwa iintlobo okuthambileyo, okanye izinto akubonakali gas ngokusekelwe abicah xa kufikwa version nzima. ingqalelo eyodwa ufanelwe uhlobo ngesixhobo optical. Ukuba embodiments yemveli ungqukuva jikelele, ukuze ube ekuthiwa-design sferotsentricheskuyu toric evumela ngokuchane ngakumbi astigmatism echanekileyo. Ngenxa yale ngobuwena ofanayo ngaxeshanye amabini amagunya enombala, oko kukuthi inzuzo main lanele se toric. Indlela banxibe iinketho ezahlukeneyo, xelela specialist.

Umahluko phakathi lens ukulenza kunye toric

lens Spherical kunye toric - yintoni na kwaye yintoni umahluko? Iindidi zokuqala banoxanduva nasekubalungiseni ukubona okanye hyperopia, ngoko okwesibini, ngenxa ukwakheka kwalo, kwangaxeshanye benze imisebenzi ezimbini okubonakalayo. Enye Isalathisi yenzelwe ukulungisa astigmatism kwi okuyi elithile, ngoxa omnye olawula acuity olubonakalayo.

lens Toric for astigmatism kufuneka ahlale endaweni enye. esiqu kufuneka ilingane ngokungqongqo kwisikhundla sokuba nezamazembe engasebenzi lokubona. Kuphela kulo mzekelo, enze yonke imisebenzi yabo. Spherical lens umfowunelwa egcine i-unamandla ozinzileyo zokunganyangeki phezu komhlaba layo lonke, ngoko ke akunamsebenzi koko isikhundla kwi inwebu na.

buhle

lens Toric banamalungelo eziliqela xa kuthelekiswa nendlela zemveli wokulungiswa mbono.

• Ngenxa ukwakheka kwalo, ukuba ngaxeshanye ukwenza imisebenzi ezimbini: Umbono echanekileyo ukuphelisa astigmatism siphene.
• Kwanikelwa indawo eyiyo kwi inwebu ngenxa ifomu kunye eyongezelelweyo "izixhobo."
• ezahlukeneyo ezifana ezilungele abo babandezeleka nje kuphela astigmatism, kodwa kwezinye kwenwebu ukugula.
• lens enjalo ukwenza indima ngelensi iliso kwimeko iye yenziwa utyando ukuze ususe cataract. Ukulungiselela le njongo, kukho toric ezizodwa lens intraocular.

Xa zisetyenziselwa ukulungisa umbono amanqaku enombala uhlobo nzima, kuba iingenelo ezongezelelweyo, phakathi kuyo ilandelayo kufuneka kuqatshelwe: inqanaba eliphezulu oxygen inwebu, ukulungisa umbono echanileyo, ukungabi isiphumo 'iliso owomileyo "nokuzabalazela protein isimemezelo. Iyahlala ixesha elide zosetyenziso - nto kwakhona iingenelo kubalulekile ukuba lens engqongqo toric. Ixabiso iinketho engaphezulwana nje kancinane kune inobulali, kwaye ngokubanzi isusela ukusuka engange-300 ukuya kuma- 3000.

ukushiyeka

lens Toric babe neengxaki ezifanayo iintlobo eqhelekileyo ethambileyo okanye ziqinile. Ngokumalunga Uhlobo lokuqala izixhobo ezisebenzisa, oko kuqala:

• ixesha elifutshane ukusetyenziswa;
• nithiywe ukufikelela oxygen inwebu, ilens ezithambileyo kuba ligubungela phantse ngokupheleleyo;
• Ukwanda iliso owomileyo, nto leyo maxa wambi ifuna ukusetyenziswa amachaphaza ezizodwa okanye gel;
• indawo kwi iidiphozithi lensi protein ukusuka iliso, nto leyo enokuthi yenze uxabane kunye nabanye.

Ngokubhekiselele kwizixhobo engqongqo, neengxaki zilandelayo:

• nzima kakhulu kwaye ukhetho ende lens toric;
• kwinqanaba elisezantsi intuthuzelo kunye nemfuneko aziqhelanise inwebu.

Kubalulekile ukuba uqaphele ixesha enye ngaphezulu. Kungakhathaliseki ukuba uhlobo ixabiso - yenye ethile, leyo kufuneka lenses toric. Ixabiso iinketho iphezulu kakhulu, kungakhathaliseki ukuba athambe okanye kunzima ukuba. Oku kungenxa yokuba omabini nzima neengxaki ukubona okanye ezikude, kwaye astigmatism siphene iyapheliswa. Ukongeza iindlela ezizodwa lens kwi inwebu usebenzisa indawo echanekileyo, enokungena ixabiso.

Indlela ukukhetha?

Ukukhethwa lens toric kufuneka lwenziwe zamehlo onamava, kuba kubalulekile ukuqwalasela amagunya ezimbini okubonakalayo. Kubalulekile kwakhona ukuba ukugqiba udidi - soft okanye nzima. I ukhetho lokuqala ukhululeke ngakumbi, kodwa kwesibini iingenelo olongezelelweyo. Ukuba umntu lukhetha lona engqondweni nzima, kubalulekile ukukhumbula ukuba imveliso ngokutsha ukwenzela inwebu, ngoko emva kokuba uphethwe kuyimfuneko ukuba alinde de ilens engqongqo iza kwenziwa ngamnye.

Ukongeza imisebenzi yayo enombala, Ukrainian lunee ntlobo enjalo nayo nomphumo zokuhombisa. Ukuze ezi njongo, ungasebenzisa lens elimbala toric. Baya mbono kuphela ilungile, kodwa kancinci ukutshintsha inkangeleko yazo.

iindlela uvala

Mu kuya kwa nshita ukulenza, lens toric uya kakhulu ngempumelelo kuphela xa lumiswe ngokuchanekileyo. Kwimeko enjalo icandelo zezindlu iya kujolisa kuzo zone elilelona inwebu aspherical. Oku kuya kuvumela kwesiphumo ulungiso astigmatism, okuye lenses toric. Njengoko ukuguga loo lobeko iya kuxhomekeka iimpawu uyakwazi lutshixo lusetyenziswayo. Zazo ezininzi:

• zokulinganisa Prismatic. Ubukho a uPienaar encinane kwindawo esezantsi lens. Phantsi yempembelelo womxhuzulane isixhobo enombala uya kungena kwindawo echanekileyo.
• Periballast. Kulo mzekelo, ilens unalo kummandla luthe phezulu nasezantsi, ezithi zibekwe phantsi iinkophe. Oku kukuvumela ukuba uhlale kuyo sikhundla.
• Clip. Ukulungiselela le njongo ezantsi ilens ziguyiwe nxenye ithile, yaye nalo eli cut it iqhotyoshelwe apha kumazantsi kwinkulungwane.

Ukuze ufumane i-nitrogen ichanekileyo ngaxeshanye abenzi abaninzi basebenzisa ezininzi yezi ndlela.
