Posterior Capsulorhexis for Draining Berger Space

Abstract

Lens material can be detected behind posterior capsule in case of infusion misdirection syndrome development during phacoemulsification. This condition is associated with Wieger ligament damage. There is no accepted management options for this issue. Authors offer original technique of small diameter (2–3 mm) posterior capsulorhexis performed before IOL implantation for evacuation of infusion fluidics and lens material from Berger space. Safety of new technique was evaluated by OCT images analyzing central foveal thickness in 1 day, 3 weeks and 6 weeks after cataract surgery. There were 3 patients groups: I — uneventful phacoemulsification (10 eyes) (control group); II — phacoemulsification with development of infusion misdirection syndrome and lens material behind posterior capsule without performing posterior capsulorhexis (10 eyes); III — phacoemulsification with development of infusion misdirection syndrome performing posterior capsulorhexis for draining Berger space. There was no significant difference in central foveal thickness between patients groups. There was trend of central foveal thickness increase in 3 weeks after surgery in all groups. Central foveal thickness returns to initial values in 6 weeks after surgery in all patients groups. There was no cases of cystoid macular edema in study. In conclusion, small diameter posterior capsulorhexis technique is useful in clinical practice for evacuation of infusion fluidics and lens material from Berger space before IOL implantation.
