Is a canthopexy without infraorbital rim implant, sufficient and reliable? (photo)

I live in contienental Europe. I still didn't see an oculoplastic surgeon to discuss a possibility of having a canthopexy to make my eye external canthus neutrally aligned and have more narrow eyes. My question is, since I didn't find oculoplastic surgeons familiar with the Infraorbital rim implants....is it safe to go with the canthopexy option, alone... without Infraorbital rim implants ? Will the Infraorbital rim implants, help keeping the canthopexy from deteriorating?
