Abstract:AIM:To evaluate the clinical features of posterior polar cataract and the surgical technique of phacoemulsification in eyes with posterior polar cataract·METHODS: Case series of 12 patients(17 eyes) with posterior polar cataract who were treated in our hospital from October 2009 to March 2011 were collected.Patients underwent complete ophthalmological examinations including visual acuity,slit-lamp microscopy,and indirect ophthalmoscopy or B-scan ultrasonography.Under peribulbar anesthesia,phacoemulsification was carried out in all cases with foldable intraocular lens(IOL) implantation.The surgical technique,preoperative and postoperative visual acuities,and intraoperative complications were evaluated·RESULTS:All eyes were implanted foldable IOL.Eleven eyes revealed intact and transparent posterior capsule,four eyes revealed posterior capsule opacification which needed YAG laser capsulotomy later.Two eyes developed posterior capsule rupture in which one occurred during division of nucleus and another during aspiration of epinucleus.Fifteen IOL were implanted in the capsular bags,while two IOL were fixed in the ciliary sulcus.In all,16 eyes achieved a best-corrected visual acuity of 20/40 or better one month after operation·CONCLUSION:Phacoemulsification with foldable IOL implantation is an effective and safe method to treat posterior polar cataracts.By continuous curvilinear capsulorhexis,performance of careful and gentle hydrodelineation without hydrodissection,low power,low vacuum and low flux phacoemusification parameters setup,manual aspiration of epinucleus and cortex surgical technique,intraoperative complications could be decreased.
