Njengoba ezothatha isikhundla lens iso

izifo ezihlukahlukene iso zidinga ngezinye izikhathi esikhundleni lens. Okuvame kakhulu isifo ezinjalo kuba cataract. Kuqakatheke ngani ukufaka esikhundleni i-lens empunga?

ushintsho olumayelana nohlelo ubudala kuhilelani kahle kwegazi emzimbeni, ngaleyo ndlela ngincipha iso ingcindezi okuholela ingaphazamisi biconvex esweni. Ukudla emizimbeni buthaka, okwaba nomthelela ekwakhekeni lesi sifo. Njengoba ezothatha isikhundla lens ezimweni ezinjalo, umane kudingeka, ngoba inattention sifo kungaholela ukuqedela ngobumpumputhe.

Okokuqala, isiguli kumele zihlolwe nguchwepheshe. Udokotela wezifo zamehlo efaka ukusazi ngokunembile isifo esikuphethe futhi ukunquma degree of turbidity. Isolezwe futhi ekhethiwe udokotela. Kubalulekile kakhulu ukukhetha lens afanele, ngoba kudingeka esikhundleni lens, ngokuba nomzimba angaphandle. Ngakho-ke, usayizi kufanele zifane ncamashi, ke kungenjalo zinganqatshelwa.

Ngaphezu kwalokho, iziguli ibhekane babonisana saziso nge udokotela. Udokotela kufanele asuse zonke izinhlobo yezinkinga e esimiso senhliziyo nemithambo yegazi njengoba yokusabela kuya izinzwa, nakuba wendawo kuphela.

Ukuhlinzwa ukuba esikhundleni lens esiqhutshwa ehhovisi umtholampilo. Isiguli ngesikhathi ukusebenza usesimweni lisalele. Udokotela ihlola inqubekelaphambili yomsebenzi ngokusebenzisa isibonakhulu, okuyinto igibele ngaphezu nesineke. Isithombe microscope kukalwa khona esibukweni zhidokristallichesky elenga odongeni. Njengoba ezothatha isikhundla lens akusho kuthathe imizuzu engaphezu kuka nanhlanu.

Isiguli ngosizo abasebenzi bezokwelapha kubeka etafuleni. Iso iqinile kule sikhundla evulekile. Anesthesia uthathe isinyathelo, ngakho isiguli akusho ukuzwa ukungakhululeki.

Ukuze wenze mikronadrez, udokotela usebenzisa ithuluzi idayimane eziyisithupha amamilimitha angu eside. Khona-ke, into ekhethekile yethulwa, okuzokwenza ukuvikela iso phakathi nokuhlinzwa. Lokhu viscoelastic. In the isinyathelo esilandelayo uphenyo busuka iso, ekhuthaza ngokuningiliziwe ukuguquka kwabantu abathintekayo crystalline lens e emulsion nokususwa kwalo okwalandela kusukela iso. Ngaphambi udokotela wakho ine umsebenzi onzima: ukulondoloza ifilimu, elalikade kwaba "wangempela" lens. Siyabonga ekulondolozweni ifilimu lifinyelele izinga eliphakeme kakhulu sokusinda yomzimba entsha ehlweni lomuntu.

esikhundleni Eminye lens Kwenziwa ekugxiliseni eligoqiwe lens intraocular okuyinto lihlelwe ngokuzimela futhi fixed ehlweni. Isigaba akuyona sutured. Eye ingcindezi ikhuthaza ezimele "ivaliwe" imbobo.

Isikhathi nokuvuselelwa liyadingeka emva kokuhlinzwa. Ungakwazi ngokushesha babuyele emsebenzini futhi waphila ukuphila okuvamile. Okuvumelekile sisebenza kuphela ukuthi siphakamise izinto ezisindayo. Phakathi eyodwa amasonto amabili akufanele iyophakanyiswa amakhilogremu angaphezu kwamabili.

Abakhiqizi ozama bebambisana ngangokunokwenzeka ne lens yokufakelwa samanje. Ngakho-ke, akunakwenzeka ukuba uthole ukuthi iyiphi i-lens engcono. isihlungi Yellow in the lens oluhambisana womuntu. Kanti futhi uphinde abe "yisihlangu" ngokumelene ultraviolet okwesibhakabhaka, ngaleyo ndlela kuncishiswe ingozi yokuba nezifo ezihlobene nokukhula ngwengwzi esweni. Njengoba ezothatha isikhundla iso lens lens aspherical kuletha ukucaca enkulu ebumnyameni. Aspheric - abe enamathela ifomu ekhethekile. Ukusetshenziswa lens multifocal inikeza umbono omuhle kanye aseduze nakude. Yomiselela lens akkomodiruschey lens kukuvumela zisebenzisa imisipha iso, kokulingisa kwaqeda ikhono lemvelo ngokugxila. Amadivayisi anjalo optical eduze ngangokunokwenzeka lens zemvelo. Lapho kuvela izinkinga ka cataract esikhundleni lens astigmatism ikhiqizwa esebenzisa lens toric.
