·AIM:To investigate the effect of phacoemulsification and intraocular lens(IOL)implantation in treatment of high myopia.·METHODS:Phacoemulsification and IOL implantation was performed in 42 cases 55 eyes wih high cateract.·RESULTS:One month after phacoemulsification,the best-corrected visual acuities were≥ 0.5 in 27 eyes(49%),0.3-0.4 in 16 eyes(29%),<0.3 in 3 eyes(5%),where these 46 eyes ocular axes were from 24.26 to 30mm;the the best postoperative corrected visual acuities were all <0.5,0.3-0.4 in 3 eyes(5%),<0.3 in 6 eyes(11%),where these 9 eyes’ ocular axes were>30mm.·CONCLUSION:Phacoemulsification and IOL implantation is a safe and effective mothed for treating high myopia and correcting refractive error.·
