Background

The Posterior Cataract (PCO) is a common long-term complication of cataract phacoemulsification surgery, and is related to factors such as the surgical operation technology of operators, the material and design of artificial lenses, etc., and the literature reports that the incidence rate of PCO for three years is about 15%, the clinical incidence rate is generally 20% -60%, and the incidence rate of cataract of infants reaches 100% [1]. With years of effort improvement by clinicians, the incidence of PCO has decreased, but is still a long-term complication that plagues cataract surgeons. Common complications after intraocular lens implantation into the human eye are postoperative capsular opacification (posterior capsuleopacification, abbreviated PCO), anterior capsular opacification (anterior capsule opacifieation, abbreviated ACO), anterior capsular contracture, which are essentially caused by proliferation of residual Lens Epithelial Cells (LEC) in cataract surgery. The most commonly used way to prevent post-operative PCO is to make the edge of the back surface of the crystalline optic zone sharp. The rear surface of the crystal optical area is closely attached to the rear capsule. The posterior capsule is bent and shrunk at the included angle of the edge of the optical zone, so that LEC cells are blocked from migrating and proliferating to the contact part of the optical zone and the posterior capsule, and PCO is prevented.

The prior patent CN209301398U has a simple structure, but has poorer efficiency for reducing the PCO incidence, is more troublesome to use and has poor practicability, and the utility model discloses a crystal embryo structure for reducing the PCO incidence, which solves the problems.
