Clinical research of phakic posterior chamber intraocular lens implantation for high myopia / 中国医师进修杂志

ABSTRACT

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.
