Purpose: To evaluate  the outcome of treatment for  high myopia by posterior phakic intraocular lens lens implantation
 
Setting: ophthalmology department, Sohag UniversityHospital, Sohag Faculty of Medicine.
Methods: 23 eyes of 16  highly myopic patients were included in the study. The mean age was 25.4 years (range 18 to 35 years), the mean spherical equivalent (SE) -14.64 diopters (D) (range 8 to 28 D), , 23 eyes of 16 patients received posterior chamber phakic IOL (ICL)  10 females and 8 males the age ranges from (18-35 years).
Results The spherical equivalent refraction at the last examination was within 1.0 D of the targeted refraction in 22 eyes (91.3% ) and within 0.5 D in 11 eyes (47.8%). Onecase ( 4.3%)  complained of glare in the Ist week postoperative which improved, One case ( 4.3%)  develpoed anterior subcapsular cataract  after 1 year.
Conclusion: Surgical management of high myopia  byposterior chamber phakic IOL ( ICL) , is safe and predictable
