Factors influencing the formation of posterior capsular opacities after extracapsular cataract extraction with posterior chamber lens implant.
This study was designed to determine whether different factors could influence the formation of posterior capsular opacities. The study group comprised 271 patients who had undergone an extracapsular cataract extraction with implantation of a posterior chamber lens either with or without laser ridge. Between 12 and 25 months after surgery, a statistically significant difference was found with a lower rate of secondary cataract in the laser ridge group, but with respect to advanced secondary cataract, i.e. eyes which needed YAG capsulotomy, no statistically significant difference was found (P-value 0.99). No association was found between age or sex of patients, different surgeons or complications during or after surgery and the risk of getting a secondary cataract.
