Introduction: The posterior capsular opacity is the most frequent complication in the cataract surgery and, although capsulotomy with Nd-Yag laser is a very effective procedure to solve it, it is not free of complications. Objective: To describe the complications in patients exposed to capsulotomy with Nd-Yag laser.Methods: A descriptive and prospective study of 104 patients with posterior capsular opacity, assisted in "Enrique Cabrera" Ophthalmological Center from Havana, was carried out during the 2010. Variables of frequency and type of complication, age, sex, pathological ocular and systemic medical history, classification of the capsular opacity, energy used, as well as visual acuity before and after the treatment were analyzed.Results: The increase of the intraocular pressure and the cystic macular edema as the most common complications, the 56-75 year-old patients, female sex, as well as the capsular fibrotic opacity and the capsulotomy with more than 8,0 MJ prevailed in the case material.Conclusions: More than half of the patients presented complications of transitory and reversible type, which were not related to the quantity of energy used; the visual improvement after the procedure was remarkable.
