Objective To assess the effect on anterior chamber angle， corneal endothelial and adjacent tissue after implantation of phakic posterior chamber implantable collamer lens （PPC-ICL） for the correction of high myopia. Methods In this prospective， nonrandomized clinical study， 106 consecutive eyes of 58 patients with high myopic received ICL implantation between January 2011 and June 2013 in the Ningxia Eye Hospital. Uncorrected visual acuity（UCVA）， best corrected visual acuity（BCVA）， intraocular pressure， corneal endothelial cell count were measured preoperatively and at 1 month， 6 months and 12 months postoperatively. The ultrasound biomicroscopy （UBM） was used to observe the depth of anterior chamber （ACD） vault， angle opening distance 500 microns from the scleral spur （AOD500）， trabecular-iris angle （TIA） at point 2， 4， 8 and 10 respectively. The repeated measurement ANOVA was used to analyzed statistical data. Results The postoperative UCVA was equally or higher compare with preoperative BCVA in all patients. Intraocular pressure and corneal endothelial cell count were no statistically significant difference between pre- and postoperative （P>0.05）. The postoperaive ACD， AOD500 and TIA value were decreased significantly than preoperative at 1 month （F=12.372， 21.393， 22.076， 21.154， 21.763， 19.471， 19.823， 19.836， 19.247， P<0.05）. But there were no statistically significant difference of ACD， AOD500， vault and TIA between 1-month and 6-month， 12-month postoperatively. No pupillary block glaucoma or anterior capsule opacification occurred during the follow-up. Conclusion The structure of anterior chamber angle was stable and corneal endothelial cell was no obvious decrease postoperatively during 1 year follow-up.
