Cataract surgery is an ambulatory procedure that like other ocular or human body surgeries is no exempt of risks. However, because the incision in the intervention is minimal, as other significant advances developed in its technology and surgical procedure, postoperative complications have been reduced considerably. Concretely, one of the most frequent complications reduced in postoperative cataract surgery is Posterior Capsular Opacity (PCO). Such opacity is produced by the proliferation and migration of residual crystalline epithelial cells that remain in the capsular bag during cataract surgery. In its beginnings, the opacification occurs in the periphery, but if it progresses will affect the central vision, inducing blurred vision as glare and contrast sensitivity alterations. In such situation, an ophthalmological revision with pupilar dilatation is necessary to know the opacity grade, as likewise plan treatment by Nd:YAG capsulotomy to restore the vision.
Due to the visual limitation that induces Posterior Capsular Opacity after cataract surgery numerous scientific studies about its prevalence in the population and its main risk factors have been conducted. Likewise, various improvements in the surgical procedure, as in Intraocular Lenses technology to prevent capsular opacity have been developed. Concretely, good cortical clean, less time of irrigation-aspiration and capsulorhexis diameter lower than the optical zone of the intraocular lens to prevent Posterior Capsular Opacity has been proposed. To reduce the incidence of Posterior Capsular Opacity also has been proposed that viscoelastic must be eliminated completely after cataract surgery, as its concentration must be low in hyaluronic acid. Besides, intraocular lenses technology has experimented important developments in its material, as optical and haptic design to reduce the incidence of Posterior Capsular Opacity. Although the risk of developing PCO months or years after cataract surgery is explained clearly in the informed consents previously to the intervention, from ConsultoriaVisual.com, we plan content marketing and social media strategies in online platforms of ophthalmological clinics and hospitals in Spanish speaking countries. Our strategies will allow that the patients have greater knowledge of PCO, as its principal innovations developed to reduce its incidence. Likewise, from our international project we edit contents for the diffusion of postgraduate courses and master’s degrees to academy community receive more information about the different training programs.
