Objective To evaluate the efficacy and safety of implanting a posterior chamber phakic intraocular lens to correct high myopia.Methods There were 117 eyes of 63 patients with high myopia.The range of preoperative myopia diopters was-5.25 ～-19.0D.The best corrected vision was ≥0.8 in 101 eyes and 0.5 ～ 0.6 in 15 eyes,and ＜ 0.3 in one eye,The examine included uncorrected visual acuity ( UCVA),corrected visual acuity,corneal endothelium,UBM,intraocular pressure,refraction,tonometry,kerameter,pachometer,axial length,depth of anterior chamber.horizontal corneal diameter (white to white),and posterior mean evaluation after indirect ophthalmoscope examination.The posterior chamber phakic intraocular lens manufactured with STAAR collamer was implanted though 3.0 mm sutureless temporal clear corneal incision under topical anesthesia.YAG laser peripheral iridectomy was performed before surgery to avoid pupil block glaucoma.The follow-up examination included visual acuity,refrection,tonometer,cornea,and space between crystal lens and IOL.Results 117 eyes implanting were successful,all eyes had a significant increase in uncorrected visual acuity,and a same or better corrected visual acuity,All eyes maintained a low negative power of refraction,but the patients managed most activities without spectacles.2 case (2 eyes) were found cataract genesis under anterior capsular membrane.Conclusion The posterior chamber phakic IOL was predictable,safe,and efficacious in the correction of high myopic.
