Objective  To investigate the effect of phakic posterior chamber implantable collamer lens （PPC-ICL） implantation surgery on the accommodative status of eyes with high myopia. Methods  The study included 30 eyes of 30 22-30 years old patients with high myopia. All patients underwent PPC-ICL surgery in the West China Hospital of Sichuan University. Monocular accommodative amplitude， positive and negative relative accommodation and accommodative facility were investigated before surgery and 1 month and 3 months after the surgery. The results were analyzed by repeat measured ANOVA. Results  Monocular accommodative amplitude had increased 3 months after surgery （F=57.909， P<0.05）. Accommodative facility had also increased 3 months after surgery （F=18.663， P<0.05）. However， there were no differences in positive and negative relative accommodation at the three time points. Conclusion  PPC-ICL implantation surgery does not cause adverse effects on accommodative function. After PPC-ICL implantation surgery， accommodative amplitudes and accommodative facility increase. But there is no significant effect on positive and negative relative accommodation.
