AIM: To evaluate the long-term safety, efficacy and stability of posterior chamber intraocular lens(ICL)implantation for the correction of myopia.

METHODS: This retrospective non-randomized study included 107 eyes of 64 patients who were performed ICL implantation from January 2013 to December 2014. The uncorrected visual acuity, corrected visual acuity, intraocular pressure, the lens vault, endothelial cell morphometry were collected preoperatively and followed at 1wk, 1mo, 3mo, 6mo, 12mo and every year postoperatively.

RESULTS: The uncorrected visual acuity(LogMAR)was 0(-0.076, 0)at 1a postoperatively, and the uncorrected visual acuity 0.096(0, 0.221)decreased until last visit after the surgery. The change of visual acuity was associated with the change of axial length. The safety index was 1.19±0.24 and the efficacy index was 1.00±0.29 at the last visit postoperatively. The toric ICL implantation was stable without rotation at the last visit postoperatively. The vault of the ICL changed significantly in 1a postoperatively, but its change was smaller after 1a postoperatively. The intraocular pressure and endothelial cell morphometry did not changed significantly in long term postoperatively. Two eyes developed anterior cataract in 3a and 5a after the ICL implantation. There were no case developed pupillary block glaucoma.

CONCLUSION: Posterior chamber ICL implantation was a safe and stable procedure for the correction of myopia and astigmatism.
