The study was designed to investigate the clinical effects of rotated-chipping phacoemulsification in front of capsule.Phacoemulsification using rotated-chipping technique in front of capsule with intraocular lens implantation was performed with medium energy and high vacuum on 50 eyes.Rotated-chipping technique was successfully completed in 46 of 50 eyes (92%), unsuccessful cases were related to shallow anterior chamber and incomplete hydrodissection.These results suggest that rotated-chipping phacoemulsification be used for cataracts with various sclerotic nuclei and it is valuable to be applied extensively.
