Hauv kev phais ophthalmic niaj hnub, ob peb cov ntaub ntawv txuas ntxiv yog qhov tseem ceeb raws li qhovOphthalmic Viscoelastic Device (OVD). Txawm hais tias thaum lub sij hawm cataract extraction, intraocular lens (IOL) implantation, glaucoma phais, los yog corneal transplantation, OVDs ua lub luag haujlwm tseem ceeb hauv kev khaws cov duab ntawm lub qhov muag, tswj qhov chaw phais, thiab txhim kho cov txheej txheem kev nyab xeeb.
Cov kws phais mob cia siab rau OVDs rau:
Khaws lub qhov tob ntawm anterior chamber
Tiv thaiv corneal endothelial cells
Tsim qhov chaw ua haujlwm ruaj khov
Txhim kho qhov pom kev pom thaum phais
Ua kom lub lens implantation thiab cov ntaub so ntswg manipulation
Txawm li cas los xij, txawm tias ntau xyoo ntawm kev siv tshuaj kho mob, ib lo lus nug tseem pheej sib cav:
Cov kws phais yuav tsum xaiv Cohesive OVD lossis Dispersive OVD?
Cov lus teb yog ntau nuanced dua xaiv ib tug universally "zoo dua" khoom. Qhov kev txiav txim siab feem ntau yog nyob ntawm cov txheej txheem phais, tus neeg mob lub cev nqaij daim tawv, theem txheej txheem, thiab kev nyiam ntawm tus kws phais.
Kev nkag siab txog tus cwj pwm rheological ntawm cov cuab yeej no tuaj yeem txhim kho kev phais thiab cov txiaj ntsig tau zoo.
Txhawm rau saib ze dua ntawm cov tshuaj sib xyaw sodium hyaluronate tsim los rau cov txheej txheem ophthalmic, tshawbSingclean ophthalmic viscosurgical ntaus ntawv portfolio.
Dab tsi yog Dispersive OVD?
Dispersive OVDs yog tus cwj pwm los ntawm lawvcov ntaub so ntswg siab - txheej muaj peev xwm thiab muaj zog adherence zog. Tsis zoo li cohesive formulations uas zoo li nyob ua ke raws li ib tug loj, dispersive OVDs kis thiab txuas mus rau ocular lug.
Lawv rheological profile feem ntau suav nrog:
Tsawg molecular cohesion
Muaj zog nto adhesion
Kev coj tus cwj pwm siab
Nce tuav ntawm cov ntaub so ntswg
Txo qis dua los ntxuav tawm thaum muaj kuab paug
Los ntawm qhov kev pom zoo ntawm kev phais, cov kws phais mob feem ntau piav qhia txog kev sib cais ntawm OVDs li "cov txheej txheem tiv thaiv."
Thaum lub sij hawm siab - zog phacoemulsification, lub zog ntawm ultrasound thiab cov kua dej turbulence tuaj yeem ua rau lub pob txha endothelium puas. Ib qho OVD dispersive tuaj yeem tsim kev tiv thaiv kev tiv thaiv thoob plaws qhov chaw endothelial.
Cov ntawv thov kev kho mob ib yam
Dispersive OVDs feem ntau nyiam rau:
Cov kab mob cataracts xav tau lub sijhawm ntev phaco
Corneal endothelial cuam tshuam
Cov txheej txheem hloov pob txha
Complex anterior ntu kev phais
Siab - cov neeg mob uas muaj kab mob cataract
Qhov zoo
Kev tiv thaiv endothelial zoo heev
Muaj zog cov ntaub so ntswg txheej muaj peev xwm
Kev khaws cia zoo dua thaum siv dej
Pab tau nyob rau hauv siab fluidic stress
Kev txwv
Txawm hais tias dispersive OVDs muab kev tiv thaiv zoo, cov kws phais feem ntau ntsib:
Kev nyuaj siab dua thiab tshem tawm
Muaj peev xwm postoperative intraocular siab nce yog tias cov khoom seem tseem tshuav
Tsawg siv qhov chaw tu
Ntau tus kws phais mob tshaj tawm tias kev tshem tawm ua tiav yuav xav tau lub sijhawm ntxiv.
Cohesive OVD yog dab tsi?
Cohesive OVDs muaj qhov sib txawv rheological profile.
Lawv feem ntau yog characterized los ntawm:
Siab molecular hnyav
Siab viscosity
Muaj zog elasticity
Qhov chaw tseem ceeb- tuav lub peev xwm
Yooj yim ntawm kev tshem tawm hauv ib qho bolus
Nyob rau hauv qis shear tej yam kev mob, cohesive OVDs nyob ruaj khov thiab tswj lawv cov duab. Raws li kev siv zog shear ntau ntxiv, lawv pom cov shear- tus cwj pwm thinning, ua kom yooj yim txhaj tshuaj.
Hauv chav ua haujlwm tiag tiag, cov kws phais mob feem ntau txaus siab rau kev sib koom ua ke OVDs rau ib qho laj thawj loj:
lawv tsim thiab tswj qhov chaw zoo heev.
Thaum lub sij hawm phais mob cataract, kev tswj cov anterior chamber stability yog qhov tseem ceeb. Lub chamber ruaj khov txhim kho qhov tseeb thaum lub sij hawm capsulorhexis, phacoemulsification, thiab IOL insertion.
Cov kws phais mob feem ntau piav txog kev sib koom ua ke OVDs li muab:
Zoo dua chamber tsim
Kev pom kev phais kom pom tseeb dua
Ib qho yooj yim ntsuas manipulation
Kev tshem tawm ntau dua
Rau cov txheej txheem cataract niaj hnub, qhov no feem ntau txhais mus rau hauv kev txhim kho kev ua haujlwm zoo.

Cohesive vs Dispersive OVD: Nkag siab qhov txawv qhov tseem ceeb
Es tsis txhob nug seb OVD yog "zoo tshaj plaws," cov kws phais feem ntau nug:
OVD twg yog qhov zoo tshaj plaws rau qhov kev phais mob no?
| Feature | Cohesive OVD | Dispersive OVD |
|---|---|---|
| Molecular Luj | Siab dua | qis |
| viscosity | Siab | Nruab nrab |
| Elasticity | Siab | qis |
| Cov ntaub so ntswg Adhesion | qis | Muaj zog |
| Chaw Kho Mob | Zoo heev | Nruab nrab |
| Corneal Txheej | Nruab nrab | Zoo heev |
| Chamber Stability | Zoo heev | Nruab nrab |
| Kev tshem tawm yooj yim | Yooj yim heev | nyuaj dua |
| Cov yam ntxwv txhaj tshuaj | du | Hloov pauv |
| Kev xaiv phais mob | Chamber creation | Cov ntaub so ntswg tiv thaiv |
Kev sib piv qhia tau hais tias qhov tseeb tseem ceeb:
Cohesive OVDs excel attsim thiab tswj qhov chaw, thaum dispersive OVDs zoo ntawmtxheej thiab tiv thaiv cov ntaub so ntswg.
Tsis yog tus yam ntxwv ib leeg txiav txim siab zoo dua.
