Clinical research of phakic posterior chamber intraocular lens implantation for high myopia

Objective To investigate the clinical efficacy and safety of phakic posterior chamber intraocular lens (ICL) implantation for high myopia. Methods Twenty-four eyes of 12 patients with high myopia were treated with ICL implantation. The best corrected visual acuity, intraocular pressure and lens changes shape between post-operative and pre-operative were compared. Results Successful implantations were done in all patients. All eyes had a significant increase in uncorrected visual acuity. Exactly improved visual function in patients with high myopia status. The intraocular pressure was ( 14.26 ± 2.13) mm Hg(1 mm Hg = 0.133 kPa) of pre-operative , and was ( 14.79 ± 2.77) mm Hg at 1 year after post-operative, the intraocular pressure was stability after the operation. UBM showed that there was a certain gap between ICL and the lens. During the follow-up period,no complications such as cataract,chronic uveal infusion were found. Conclusion Phakic posterior chamber ICL implantation is effective,safe and reliable method for the correction of high myopia. Key words: Myopia;  Lens implantation, intraocular
