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

Abstract

Background: Phacoemulsification can cause changes in the measurements of the anterior segment. Anterior segment optical coherence tomography [AS-OCT] is a disconnected probe device that can detect variations in the anterior segment parameters. The aim of the work: The current study aimed to investigate changes in anterior chamber angle [ACA] morphology and intraocular pressure [IOP] after phacoemulsification of cataract and intraocular lens implantation by comparing two groups of patients using two brands of IOL [Sensar 1 hydrophobic one-piece IOL] and [Eyecryl hydrophilic one-piece IOL] in patients with senile cataract using [AS-OCT]. Patients and Methods: Our study was a prospective randomized study including 30 eyes with impaired vision due to cataract, as the only cause of visual regression selected from the patients who attended Al-Azhar University Hospital [Damietta branch] Ophthalmic outpatient Clinic and were randomized into two groups. Group A [15 eyes] was implanted with [Sensar 1 hydrophobic IOL] and Group B [15 eyes] was implanted with [Eyecryl hydrophilic IOL]. Results: the results revealed that there was a significant increase in the AC angle in both groups, except for the AC depth in group A, but the difference between groups was statistically non-significant. Conclusion: Phacoemulsification with IOL implantation led to an increase in the ACA, a marked increase in BCVA and a reduction in IOP, if using [Sensar 1 hydrophobic one-piece IOL] or [Eyecryl hydrophilic one-piece IOL]. However, we cannot generalize the results because of the small sample size.
