AIM: To evaluate the short-term efficacy of posterior chamber phakic intraocular lens implantation for moderate to high myopia.METHODS: Fifty-three eyes of 27 patients with moderate to high myopia(-3.25 to -21.5D)were received posterior chamber phakic intraocular lens implantation with 2.8mm clear corneal incision. Changes of visual acuity, intraocular pressure(IOP), counts of endothelial cells and surgically induced astigmatism at 1mo after surgery were observed. RESULTS: The preoperative best corrected visual acuity(BCVA LogMAR)were 0.05±0.18, the postoperative BCVA at 1d were 0.02±0.14, the postoperative BCVA at 1wk were -0.05±0.11, the postoperative BCVA at 1mo were -0.07±0.10. The postoperative BCVA were statistically significant differences in different time(P2, the postoperative endothelial cell count at 1d was 2917.1±299.0/mm2; the postoperative endothelial cell count at 1wk was 2902.5±288.6/mm2; the postoperative endothelial cell count at 1mo was 2855.3±284.2/mm2. The postoperative endothelial cell count was not statistically significant differences in different time. The preoperative IOP was 15.8±2.5mmHg; the postoperative IOP at 1d was 15.3±2.9mmHg; the postoperative IOP at 1wk was 17.4±5.8mmHg; the postoperative IOP at 1mo were 15.8±2.6mmHg. The preoperative IOP was significantly different compared with postoperative IOP at 1d, 1wk and 1mo. The postoperative IOP at 1d and 1wk were statistically significant differences(PPCONCLUSION: Posterior chamber phakic intraocular lens implantation for moderate to high myopia were safe, effective and predictability. But long-term effect remains needed to be further follow-up.
