Background:To use theSirius imaging system to precisely evaluate the changes in the anterior chamber depth(ACD)and angle(ACA)before and after phacoemulsification of intumescent cataract in eyes with different axial lengths.
Subjects and Methods:A prospective study that included patients with intumescent cataract in one eye.All eyes were subjected to full ophthalmic examination, IOP, gonioscopy and axial length measurement.Anterior segment imaging of both eyes using Sirius system to determine the ACDand ACA.Eyes were classified into three groups according to their axial lengthGroup I:axial length24.5mm.Postoperative examinations were performed at1day,1week,1month and3months.
Results:The study enrolled 32eyes;Group I included 11eyes,Group II included 11eyes andGroup III included 10eyes.Before surgery,the meanACD was2.03±0.46mm in Group I,2.2±0.42mm inGroup II and2.62±0.37mm inGroup III(P
