Abstract

Background: Phacoemulsification is widely recognized as the prevailing ocular surgical procedure conducted on a global scale. Multiple studies have provided evidence of a decrease in intraocular pressure (IOP) following phacoemulsification. The assessment of anatomical features in the anterior chamber has emerged as a key area of interest in determining the extent of IOP reduction following cataract surgery. Anterior Segment Optical Coherence Tomography(AS-OCT) has recently emerged as an objective and noninvasive method to assess the anterior chamber anatomy. Aim of the work: The aim of the work is to study the effect of phacoemulsification on the anterior chamber and IOP in glaucomatous patients and non-glaucomatous patients using AS-OCT. Patients and methods: The study was conducted on 25eyes of known glaucomatous patients and 25eyes of non-glaucomatous patients. All patients had IOP measurement and AS-OCT before and 3months after phacoemulsification. Results: Mean IOP was 17.34mmHg preoperative, 15.82mmHg postoperative with mean change -1.52mmHg in the non-glaucomatous group, 17.53mmHg preoperative, 16.12mmHg postoperative with mean change -1.41mmHg in glaucomatous wide-angle group and 18mmHg preoperative, 15.88mmHg postoperative with mean change -2.13mmHg in glaucomatous narrow-angle group. Anterior chamber parameters measured by AS-OCT showed marked widening in all groups. Conclusion: Phacoemulsification can decrease IOP and improve the morphology of the anterior chamber which may be of marked benefit for the glaucoma patients. AS-OCT offers a very useful tool for assessment of the anterior segment parameters. IOP changes after cataract surgery can be correlated with anterior segment parameters measured by AS-OCT.
