Anterior Chamber Configuration Changes after Phacoemulsification and Intraocular Lens Implantation Measured by Anterior Segment Optical Coherence Tomography

Background: Phacoemulsification can induce changes in anterior segment parameters. Anterior segment optical coherence tomography (AS-OCT) is a disconnected probe device that can detect these changes in anterior segment parameters. Objective: Was to investigate the change of the anterior chamber angle morphology and intraocular pressure (IOP) after phaco-emulsification cataract surgery and IOL implantation with comparing two groups of patients by two brands of IOL (hydrophobic one-piece IOL) and (hydrophilic one-piece IOL) in patients with senile cataract using anterior segment optical coherence tomography (AS-OCT). Patients and methods: Our study was a prospective randomized study including 30 eyes with visually significant cataract, as the only cause of visual impairment selected from those attending Al-Azhar University Hospital (Damietta branch) Ophthalmic outpatient Clinic and was randomized into two groups. Group A (15 eyes) was implanted with (hydrophobic IOL) and Group B (15 eyes) was implanted with (hydrophilic IOL). Results: the results revealed that there was a significant increase in the anterior chamber angle in both groups, except for the anterior chamber depth in group A, but there was no significant difference between the groups. Conclusion: Phacoemulsification with IOL implantation results in widening of the ACA, marked increase in BCVA and reduction of IOP, if using (Sensar 1 hydrophobic one-piece IOL) or (Eyecryl hydrophilic one-piece IOL) but we can not generalize the results due to the small sample size.
