HERNANDEZ LOPEZ, Iván et al. Strategies for the prevention of the posterior capsule opacification. Rev Cubana Oftalmol [online]. 2010, vol.23, suppl.1, pp.608-623. ISSN 0864-2176.

The posterior capsule opacification (PCO) is the most important aspect in the cataract surgery nowadays. It continues being the more frequent late postoperative complication after cataract surgery associated with decrease of the visual acuity and other visual problems that lead to important social, economical and medical impacts. The laser capsulotomy is an effective procedure for the treatment of this complication but it is far from being the ideal method since it can be associated to considerable complications. This is the reason why several research studies recently have directed their attention to PCO-preventing strategies such as the design of intraocular lenses, modified and/or improved surgical techniques, additional implants, use of cytotoxic agents and drugs as well as new technologies. The gene therapy, among the novel interventions in study, seems to be a promising strategy in this field. Up to the present, there is not a unique method that avoids in a definitive way the development of the capsular opacification. The ophthalmologists should use the combination of all these methods available which have demonstrated a proved effectiveness in the reduction of PCO. Attaining long-term excellent visual result is the main purpose of the modern cataract surgery as well as paving the road towards novel surgical interventions for the treatment of presbyopia in patients older than 40 years. In order to achieve that goal, it is essential to avoid the opacification of the posterior capsule, even more with the use of multifocal and accommodative lenses that are more vulnerable to the opacity than the monofocal lenses. Therefore, we may dare to say that the biggest breakthrough in the modern cataract surgery is still awaiting: the definitive eradication of posterior capsule opacification.
