In kasta oo tirada muraayadaha indhaha ee hydrogel-ka ay ka sarreeyaan, haddana had iyo jeer ma ahayn kuwo ku qanacsanayn awoodda oksijiinta. Laga bilaabo hydrogel ilaa silicone hydrogel, waxaa la dhihi karaa in la gaaray boodbood tayo leh. Haddaba, maadaama isha ugu fiican ee taabashada hadda jirta, maxaa wanaagsan oo ku jira silicone hydrogel?
Silikoon hydrogel waa walax aad u hydrophilic ah oo dabiici ah oo leh awood oksijiin oo sareysa. Marka laga eego dhinaca caafimaadka indhaha, arrinta ugu muhiimsan ee muraayadaha indhaha ay tahay inay wax ka qabtaan waa in la hagaajiyo awoodda oksijiinta. Muraayadaha caadiga ah ee hydrogel waxay ku tiirsan yihiin biyaha ku jira muraayadda si ay oksijiin ugu gudbiyaan cornea, laakiin awoodda gaadiidka ee biyuhu aad bay u xaddidan tahay waxayna si fudud u uumi baxdaa.Si kastaba ha ahaatee, ku darista silikoonku waxay samaysaa farqi weyn.Monomers-ka silikoonkaWaxay leeyihiin qaab-dhismeed dabacsan iyo awoodo hoose oo u dhexeeya molecular-ka, milmida oksijiinta ku jirtana aad bay u sarreysaa, taasoo ka dhigaysa marin-u-helka oksijiinta ee silikoon hydrogels inay shan jeer ka badan tahay tan muraayadaha caadiga ah.
Dhibaatada ah in marin-u-helidda oksijiinta ay ku xiran tahay biyaha ayaa la xalliyay,iyo faa'iidooyin kale ayaa la keenay.
Haddii biyaha ku jira muraayadaha caadiga ah ay kordhaan, marka waqtiga xirashadu sii kordho, biyuhu way uumi baxaan oo way buuxsamaan iyadoo ilmadu soo baxayso, taasoo keenta qallayl labada indhood ah.
Si kastaba ha ahaatee, silicone hydrogel wuxuu leeyahay biyo ku filan, biyuhuna way xasilloon yihiin xitaa ka dib marka la xidho, sidaa darteed ma fududa in la soo saaro qalalan, muraayadaha indhahana waa kuwo jilicsan oo raaxo leh iyagoo u oggolaanaya in xuubka indhaha uu si xor ah u neefsado.
Natiijo ahaan
Muraayadaha indhaha ee laga sameeyay silicone hydrogel had iyo jeer waa kuwo biyo leh oo neefsan kara, taasoo hagaajinaysa raaxada iyo yareynta dhaawaca indhaha, faa'iidooyin aan la barbar dhigi karin muraayadaha indhaha ee caadiga ah.Inkasta oo silikoon hydrogel loo isticmaali karo oo keliya in lagu sameeyo muraayadaha la tuuri karo ee wareega gaaban ah oo aan lagu dabaqi karin muraayadaha la tuuri karo ee sannadlaha ah iyo kuwa nus-sanadlaha ah, haddana waa doorashada ugu fiican dhammaan alaabada.
