Ngokuqhelekileyo, utyando lwe-cataract lwenziwa ngokutshintsha i-lens egulayo kunye ne-lens yokwenziwa ukunyanga i-cataract. Uqhaqho lwecataract oluqhelekileyo olusetyenziswa eklinikhi lulandelayo:
1. Extracapsular cataract extraction
I-capsule yangasemva yagcinwa kwaye i-nucleus ye-lens enesifo kunye ne-cortex yasuswa. Ngenxa yokuba i-capsule yangasemva igcinwe, ukuzinza kwesakhiwo se-intraocular kukhuselwe kwaye umngcipheko weengxaki ngenxa ye-vitreous prolapse iyancitshiswa.
2. Phacoemulsification cataract aspiration
Ngoncedo lwamandla e-ultrasonic, i-capsule yangasemva yagcinwa, kwaye i-nucleus kunye ne-cortex ye-lens enesifo yasuswa ngokusebenzisa i-capsulorhexis forceps kunye ne-nucleus cleft knife. Amanxeba akhiwe ngolu hlobo lotyando luncinci, lungaphantsi kwe-3mm, kwaye alufuni i-suture, ukunciphisa umngcipheko wokusuleleka kwesilonda kunye ne-corneal astigmatism. Akukuphela nje ixesha lokusebenza lifutshane, ixesha lokubuyisela lifutshane, izigulane ziyakwazi ukubuyisela umbono kwixesha elifutshane emva kokuhlinzwa.
3. I-laser ye-Femtosecond incedise i-cataract extraction
Ukhuseleko lotyando kunye nokuchaneka kwonyango lwe-laser kuqinisekisiwe.
4. Ukufakwa kwi-intraocular lens
I-lens eyenziwe nge-polymer ephezulu ifakwe esweni ukubuyisela umbono.
