1.According ga kafaffen matsayi na intraocular ruwan tabarau a cikin ido, shi za a iya raba zuwa gaban dakin intraocular ruwan tabarau da kuma na baya dakin intraocular ruwan tabarau.Ruwan tabarau na intraocular na baya (IOL) galibi ana dasa shi cikin ɗakin bayan gida saboda yawancin rikice-rikicen bayan tiyata.
2.Classification bisa ga kayan aikin ruwan tabarau na intraocular
A. Polymethylmethacrylate (PMMA): polymethylmethacrylate shine abu na farko da aka yi amfani da shi don kera ruwan tabarau na intraocular.Abu ne da aka fi so don ruwan tabarau na intraocular mai wuya.Yana da barga aiki, haske nauyi, mai kyau nuna gaskiya, kuma ba za a degraded da nazarin halittu hadawan abu da iskar shaka dauki na jiki.Ma'anar refractive shine 1.49.Rashin hasara shi ne cewa ba shi da juriya ga yawan zafin jiki da matsa lamba mai yawa.A halin yanzu, iskar ethylene oxide galibi ana amfani da ita don kashe kwayoyin cuta, kuma sassaucinsa ba shi da kyau.Akwai nau'i biyu na amfani na asibiti: ɗaya shine simintin ruwan tabarau na intraocular kuma an matse shi da kayan PMMA a lokaci ɗaya, wanda ake kira yanki ɗaya;Na biyu, ɓangaren gani na ruwan tabarau an yi shi da PMMA, kuma madaidaicin madaidaicin an yi shi da polypropylene, wanda ake kira guda uku.
B. Silicon gel: shi ne babban abu na taushi intraocular ruwan tabarau, tare da mai kyau thermal kwanciyar hankali, high-matsi tafasar disinfection, barga kwayoyin tsarin, mai kyau tsufa juriya, mai kyau biocompatibility, taushi da kuma elasticity.Za a iya dasa shi ta hanyar ƙananan ɓangarorin.Indexididdigar haɓakawa ta kasance daga 1.41 zuwa 1.46.Rashin hasara shine rashin ƙarfi mara ƙarfi, sauye-sauye a ƙarƙashin ƙarfin injina, mai sauƙin samar da tasirin electrostatic da sauƙin ɗaukar al'amura na waje.
C. Hydrogel: poly (hydroxyethyl methacrylate) abu ne na hydrophilic, tare da abun ciki na ruwa na 38% - 55%, har zuwa 60%, kwanciyar hankali mai kyau, mai kyau biocompatibility, high zafin jiki juriya da kuma babban tauri.Za a iya bushe ruwan tabarau na intraocular kuma a dasa shi.Bayan rehydration, laushinsa yana dawowa kuma tsayin layinsa yana ƙaruwa da 15%.Saboda yana da wadataccen ruwa a cikin ruwa, metabolites na intraocular na iya shiga cikin ciki kuma su manne da gurɓatacce, yana shafar gaskiya.
D. Acrylate: copolymer ne wanda ya ƙunshi phenylethyl acrylate da phenylethyl methacrylic acid.Yana da halaye iri ɗaya da na halitta kamar PMMA, amma kuma yana da laushi.Ma'anar refractive shine 1.51, ruwan tabarau na intraocular sirara ne, kuma ruwan tabarau na nadewa na iya fadada laushi da sannu a hankali.
