I-Cataract iyisifo esiyingozi esweni, okuvame ukuholela ekuqedeni ukungaboni. Indlela kuphela ephumelelayo yokuphulukisa isifo sokukhipha isifo sokukhipha isifo sokukhipha i-lens, eseyekile ukwenza imisebenzi yabo, futhi ukufaka esikhundleni sayo i-lens intraocular yokufakelwa. Ukwelapha kwangaphambi kokuhlinzwa kwakuneziqeshana zomtholampilo we-tunnel, manje ukuphazamiseka kwe-cataract ngokufakwa kwe-IOL kuyasetshenziswa kakhulu, njengendlela yesimanje kanye ne-hi-tech.
Iyini i-phacoemulsification ye-cataract kanye nokufakwa kwe-lens intraocular?
Okubalulekile kwalokhu kusebenza ukuchotshozwa nokususwa kwezindawo ezifile (ezigcwele) zelensi. Esikhundleni sezindawo ezingekho zokusebenza, ukufakelwa kufakwe - i-lens intraocular yokufakelwa elithambile. Inememori yefomu futhi ithatha ngokuphelele imisebenzi ye-lens elimelekile.
Iyiphi inqubo ye-ultrasound phacoemulsification ye-cataract nokufakwa kwe-IOL?
Ukulandelana kwezenzo ngesikhathi sokuhlinzwa:
- I-anesthesia yendawo.
- Ukwenziwa ngephambeni le-incne cornea kuze kube ngu-2 mm ubude.
- Isingeniso sedivayisi ye-ultrasound ekamelweni elingaphakathi leso.
- Ukujova ngesikhathi esisodwa kwe-viscoelastic ukuvikela izakhiwo zamehlo zangaphakathi.
- Ukubunjwa kwesikhokhelo ku-capsule yelensi.
- Ukuchithwa nokuguqulwa kwe-turbidity ibe emulsion.
- Ukuphumelela kwezicubu ze-lens ezilimele.
- Isingeniso nge-incision kwi-capsule ye-IOL eguquguqukayo, eyayiphakanyiswe ngaphambili nge-tube.
- Geza i-viscoelastic ekamelweni elingaphakathi leso ngokusebenzisa isisombululo sokunisela.
I-lens yangaphakathi ye-intraocular, engena emgodini we-lens, iqondisa lapho ngokuzimela, ithola isimo esifanelekayo futhi ilungise ngokuphepha.
Kufanele kuqaphele ukuthi, ngenxa yobungako obukhulu be-incision ku-cornea, akukho suturing edingekayo ngemuva kokusebenza. Ngakho-ke, isikhathi sokuphumula sithatha isikhathi esincane, futhi ngokujwayelekile, ukungenelela kokuhlinzwa akuyona into ephazamisayo.
Izinkinga zokuphazamiseka kwe-cataracts ne-IOL implantation
Imiphumela engenzeka yokusebenza:
- umonakalo wegament ligament;
- ukufuduka kwe-IOL;
- ukulimala okwesithathu kwe-cornea kusuka ku-ultrasound;
- ukuphuka kwe-capsule ye-lens;
- ukulahlekelwa komzimba we-vitreous.
Kubalulekile ukukhumbula ukuthi ubungozi bokucindezeleka buxhomeke ngokuqondile emsebenzini wokuhlinza.
