摘　　要：Background:Type 2 Peters ano maly is a rare anted or segment disorder characterized by central corneal leukoma with keratolenticular adhesion and cataract.Performing cataract surgery without corneal tissue transplantation in patients of type 2 Peters anomaly is extremely rare and challenging.We present a case of type 2 Peters anomaly treated by peeling off the adhesion without penetrating keratoplasty(PKP),in which restoration of corneal transparency is observed.Case presentation:An 11-month-old female infant of type 2 Peters anomaly presented with bilateral corneal opacity with distinct demarcation,keratolenticular adhesion and cataract,which was first noted at the age of 3 months.By peeling off the adhesion from comeal endothelium combined with lensectomy and vitrectomy,there was a gradual reduction in corneal opacity and improvement in visual acuity after surgery over a 2-year period.The visual acuity had improved from light perception preoperatively to 20/50 at the latest follow-up.No sight-threatening postoperative complications were noted.Conclusion:It is safe and effective to peel off the keratolenticular adhesion in patients of type 2 Peters anomaly presented with distinctly demarcated corneal opacity.
