ukwanda semithambo le inwebu

iziphumo ezifana lens ukuguga, njengoko kunyebeleziso imithambo yegazi inwebu, kungaba yinto embi kunene xa umbono yabantu. Isizathu soku idla isicelo lens ezithambileyo, ezo musa ukuvumela ioksijini emoyeni ukuya inwebu, kwaye iqalisa ukuba yindlala.

keratitis amagciwane

Kukho nezinye iziphumo engasi enxibe lenses, ezifana keratitis ngeentsholongwane. Lo bunzima kakhulu kwaye iyingozi. Esi sifo kungakhokelela ekulahlekeni mbono.

Ngaphandle kwento yokuba iliso kuphela luthintela usulelo nakukuba umphezulu waso icocwe iminyaka, iinyembezi babehlamba inwebu, iiseli lixesha kufa, yaye endaweni zabo ezintsha, ngokufuthi kukho abantu abaphethwe keratitis ngeentsholongwane. Amaninzi ke abo banxiba lens ngokuqhubekayo inyanga okanye ngaphezulu. Ngeli xesha kwi magciwane iliso umphezulu kuyilwa, ezifana Staphylococcus aureus kunye Pseudomonas aeruginosa, ezo unobangela sifo.

Iimpawu zesi sifo:

• A nokushisa emehlweni.
• Ukoyika bokukhanya.
• Ngamaxesha athile ukuphalaza iinyembezi.
• Ubomvu.
• Liyancipha umbono.
• kulandelana Rapid.

Izizathu ngenxa enokuba khona keratitis ngeentsholongwane:

• Ukunxiba lens ixesha elide ngaphandle kokuphazanyiswa.
• lens Replacement kunqabile kakhulu.
• Seswekile okanye iliso ukulimala.
• "Iliso Dry".

Acanthamoeba keratitis

Esi sifo enqabile ngokwaneleyo, kodwa eyingozi kakhulu, ngokungathi awuqali ixesha unyango, ukuba singalahlekani umbono kuphela, kodwa amehlo.

Unobangela wale sifo acanthameba into ephilayo ngokulula emhlabeni, amanzi, nokuba okusela. Oku kungavela phezu naluphi na uhlobo lenses contact.

Ngoko ke musa ukunxiba iilensi xa siqubha echibini, esemanzini, okanye sokuhlambela. Ngaphezu koko, akukho mfuneko ukuhlamba okanye ukususa izitya echazwe amanzi etephini.

helcoma

Malunga izilonda kwenwebu kufuneka ndithi kuni, kakhulu, ngokuqwalasela iziphumo lens kukuwohloka nobomi elide kococeko lomntu buqu amahlwempu. Kwakhona, esi sifo kwenzeka xa kuthe umonakalo kumphezulu ocular.

isilonda kwenwebu kungaba ngeendlela ezimbini:

• Infectious.
• Abawaziyo.

ifomu eyosulelayo ngokuqhelekileyo kunye iintlungu eziqatha, iyinqambi ngobhobhozo Nanjengomvumbi of ubomvu, ngokufuthi emva nesifo epithelium kwenwebu luhlala lokuvula. Ngomhla uhlobo ezincinane eziphila phezu komhlaba iliso, isantya sophuhliso izilonda ixhomekeke. Elwa ukuba unyango kakhulu olusebenzayo.

indlela wawuqalekisa kwenzeka kakuhle kakhulu, ngaphandle imbonakalo imingxuma inwebu kwaye ngaphandle syndromes iintlungu.

ukwala kokuthile nempilo yomntu

Imiphumela emibi lens banxibe zingenzeka ngohlobo uxabane kwenzeka phezu izinto zokwakha lens ngokwayo, kwakunye amacandelo umxube kuyo phambili.

Kule ophthalmologists Kwimeko yokugqibela isincomo indawo isisombululo enye into yenziwa ngaphandle ukusetyenziswa kwisigcinakaliso.

Iidipozithi eyenza phezu komhlaba ilens nako kunokubangela amehlo uyaliwa. Kulo mzekelo, utshintsho akuqhelekanga uxabana conjunctivitis.

Ukuba umzimba kukubona umbandela ilens yenziwa apho, kufuneka indawo nje nge jonga eyahlukileyo.

Imiphumo lens wear elide kungenzeka ngohlobo conjunctivitis komzimba. Oko kukhatshwa ukurhawuzelela, lacrimation, ukoyika ukukhanya, ukudumba kunye nobunzima ngokubanzi. Kulo mzekelo, ukusetyenziswa kweziyobisi anti nokwaliwa ngohlobo amathontsi, leyo ebiqaliswe kwi-inwebu phambi kokufaka ilens kuyo.

ukuqhekeka conjunctiva

Kwiminyaka embalwa edlulileyo kwafunyaniswa wemiphumela ezingalunganga ngokunxiba lens - kuqhuma le conjunctiva. Oko kunokuthi kwenzeke ukuba ilens yenziwe abicah hydrogel. Iintanda becala kwenzeka kwiindawo apho kukho ukudibana ngohlangothi conjunctiva lens. Ngokuqhelekileyo oku yoko kwenzeka ngaphandle iintlungu okanye naziphi na iimpawu. Kwakuyeyona sizathu sokuba esi sifo a umonakalo ngomatshini okanye okuthuthuzela iliso, nto leyo edla kwenzeka xa ilens njalo isicelo.

balls mucin

Ezi amaso ingafunyanwa kwi kumphezulu engaphakathi ilens zoqhagamshelwano ngohlobo kwingxelo ezincinane ngeenxa zonke.
