Phacoemulsification Clinical Trial
Official title:
Assessment Of Anterior Chamber Configuration Changes After Phacoemulsification With Swept-Source Optical Coherence Tomography
To assess the changes of anterior chamber angle in patients with shallow anterior chamber and normal anterior chamber after phacoemulsification and intraocular lens implantation (IOL) using anterior segment swept-source optical coherence tomography (AS-SS-OCT).To observe the 60 eyes of 60 patients in our study.
This is a prospective case-control study; 60 eyes of 60 patients who underwent cataract surgery. Based on anterior chamber depth (ACD) and gonioscopy findings, the eyes are classified into two groups, shallow anterior chamber group (30 eyes) and narrow anterior chamber group (30 eyes). AS-SS-OCT was used to measure ACD and angle parameters (angle opening distance(AOD), angle recess area(ARA), trabecular iris space area（TISA）, and trabecular iris angle (TIA). Serial changes in each group were measured before and 3 months after phacoemulsification and IOL, and the differences between the two groups were compared. ;
