Ua ntej kho cov kev kho mob muaj nyob rau hauv phau ntawv qhov ciav extraction, tam sim no phacoemulsification ntawm cataract nrog implantation ntawm IOLs yog nce siv, raws li ib tug ntau niaj hnub thiab hi-tech txujci.
Qhov phacoemulsification ntawm cataracts nrog lub implantation ntawm lub lens intraocular yog dab tsi?
Tus essence ntawm lub lag luam no yog kev sib tsoo thiab kev tshem tawm ntawm cov chaw tuag (huab) ntawm lub lens. Qhov chaw ntawm cov cheeb tsam uas tsis yog ua haujlwm, muaj qhov muab cog rau - ib qho khoom muag sab nraud ntawm lub lens. Nws muaj lub cim xeeb ntawm daim ntawv thiab siv tag nrho cov kev khiav haujlwm ntawm lub lens puas.
Yuav ua li cas yog txoj haujlwm rau kev phacoemulsification ultrasound ntawm cataract nrog implantation ntawm IOL?
Kev sib lawv liag thaum lub sijhawm phais:
- Cov tshuaj loog.
- Tiav raws ntawm lub periphery ntawm cornea incision txog li 2 hli nyob ntev.
- Taw qhia ntawm ib qho ultrasound ntaus ntawv mus rau hauv lub chamber anterior ntawm lub qhov muag.
- Kev txhaj tshuaj kho ib zaug ib zaug tuaj yeem tiv thaiv lub qhov muag ntawm lub qhov muag.

- Crushing thiab transformation ntawm turbidity mus rau hauv emulsion.
- Suctioning ntawm cov lens uas puas tsuaj.
- Kev taw qhia los ntawm lub qhov muag ntawm daim npog ntawm ib qho yooj yim IOL, yav dhau los nyob rau hauv daim ntawv ntawm ib lub raj.

Cov teeb meem ntawm phacoemulsification ntawm cataracts nrog IOL implantation
Qhov yuav tshwm sim ntawm txoj haujlwm:
- kev puas tsuaj rau ligament ligament;
- tawm ntawm IOL;
- peb-raug mob ntawm lub pob kws los ntawm ultrasound;
- rupture ntawm lub capsule ntawm lub lens;
- poob ntawm vitreous lub cev.
Nws yog ib qho tseem ceeb kom nco ntsoov tias qhov kev pheej hmoo ntawm cov teeb meem nyob ntawm cov kws kho mob ntawm cov kws phais neeg.
