An overview of the influence and design of biomaterial of the intraocular implant of the posterior capsule opacification

Posterior capsule opacification remains till nowadays one of the most hypothetical problems concerning the cataract surgery. When it comes in preventing PCO, this complication is made in multiple ways that concern, along with the surgery steps, the choice for the biomaterial of the intraocular implant lens. The concern of influence of the type of the used material (hydro-phob/ hydro-philic), of the design of the implant (1-piece IOL = monobloc vs. 3 - piece IOL - multipiece) and with the design at the edge, they all have been considered in multiple studies. This article performs a synthesis of those studies and establishes conclusions regarding possible choices. Abbreviations: PCO = Posterior capsule opacification, IOL = intraocular lens; LEC = lens epithelial cells.
