Abstract

Purpose: To determine whether the infusion pressure used during phacoemulsification may have a detrimental effect on the anterior hyaloid membrane barrier (AHMB) in a pressure fluctuation-free environment using diagnostic spectral-domain optical coherence tomography (SD-OCT) postoperatively. Setting: Tandil Eye Clinic, Tandil, Buenos Aires, Argentina, and Centro Oftalmológico Dr. Charles, CABA, Buenos Aires, Argentina. Design: Prospective, randomized, multicenter, experimental, and double-masked study. Methods: Phacoemulsification with intraocular lens implantation was performed in all patients with the Centurion Vision System equipment with active fluidics and active sentry. Patients were randomly assigned to configuration 1 or 2. Configuration 1 had intraocular pressure (IOP) 30 mm Hg and configuration 2 IOP 80 mm Hg. Inclusion criteria were axial length >22mmand <25mm, age older than 50 and younger than 70 years, and complete adhesion of AHMB. Results: 80 eyes of 80 patients were included. Berger space was identified in 17 cases (42.5%) of group 2 and 3 cases (7.5%) of group 1 postoperatively using SD-OCT. A statistically significant relationship was established using Fisher exact test (P = .0003). Postoperatively, we observed posterior vitreous detachment changes in only 1 patient (1.25%) during the 3 months of follow-up (P = .5). According to the Wong-Baker FACES Scale, the patient's subjective perception was better for the low infusion pressure group (P = .0001, Fisher exact test). Conclusions: Phacoemulsification with high infusion pressure can change the vitreous-lens interface. Positive Berger space after phacoemulsification is a biomarker of this change and can occur in eyes without risk factors. Incidence is directly related to the infusion pressure used.
