Objective To observe the clinical effect of PC-PRL （phakic refractive lens）implants to correct high myopia. Methods This was a retrospective case series study. Twenty-five patients （45 eyes） with high myopia were implanted with PC-PRLs from January 2011 to May 2012. The postoperative follow-up period was 6 to 17 months （average 10.9±1.6 months）. A paired-sample t test was used to analyze uncorrected visual acuity， intraocular pressure， endothelial cell density， anterior chamber depth， and the occurrence of complications was recorded. Results Uncorrected visual acuity （UCVA） 4.5~5.2 was better than preoperative best corrected visual acuity （BCAV） for 35 eyes （78%）. The mean postoperative IOP was 13.7±4.2 mmHg， which was not a statistically significant difference from the mean preoperative IOP （13.9±4.1 mmHg）. The mean postoperative endothelial cell density was（2609±296）cells/mm2， which was not a statistically significant difference from the mean preoperative endothelial cell density（2818±327）cells/mm2. The stability of PC-PRLs was high， average high arch was （0.380±0.135）mm， and there were no artificial crystals close to crystal position. Conclusion PC-PRL implantation to correct high myopia is effective and safe and is the ideal treatment for patients with high myopia.
