Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Group:Traditional ultrasonic biological
The measurement of axial length was performed in 60 eyes (30 eyes for each group) with senile cataract of vitrectomised eye of diabetic retinopathy using lenstar and traditional ultrasonic biological combined with cornea curvimeter.In this group,we use traditional ultrasonic biological combined with cornea curvimeter to measure the ocular parameter.
Traditional ultrasound biometrics
To evaluate the clinical feasibility of using a new optical coherence interferometry ( lenstar ),comparing with traditional ultrasonic biometry and keratometry in the accuracy and characteristics for intraocular lens calculation of cataract after PPV
Group:Lenstar
