Supracapsular implantation with optic capture of the posterior chamber intraocular lens in pediatric cataract / 眼科

ABSTRACT

Objective To assess the clinical effects of supracapsular implantation with optic capture of the posterior chamber intraocular lens in pediatric cataract.Design Retrospective case series.Participants 15 cases(17 eyes)with pediatric cataract.Methods Phacoemulsification,posterior continuous curvilinear capsulorhexis,about 4 mm in diameter,supracapsular implantation with optic capture of the posterior chamber intraocular lens in pediatric cataract were performed.Main Outcome Measures Preoperative and postoperative visual acuity,intraocular pressure,position of IOL,intraoperative and postoperative complications.Results Implantation of optic capture of the posterior chamber intraocular lens was successfully performed in 17 eyes.Positions of IOL were changed in 5 eyes after operation 6 months,from post-capsule to supra-capsule.Among these 5 eyes,opaque optic axis were found in 4 eyes.No optic axis opaque was found in 13 eyes with optic capture.The major complications of optic capture were lenticular precipitatesgrade 1 in 3 eyes(18%);grade 2 in 7 eyes(41%).Anterior synechia of iris occurred in 1 eye(6%);posterior synechia of iris in 4 eyes(24%).Pupil deformity occurred in 5 eyes(29%).Conclusions Posterior continuous curvilinear capsulorhexis and supracapsular implantation with optic capture of the posterior chamber intraocular lens are safe and effective in the treatment of pediatric cataract,especially in the prevention of secondary opacification from the visual axis.
