VIDAL CASTILLO, Malvys et al. Changes of the corneal endothelium in sequential cataract surgery with vitrectomy. Rev Cubana Oftalmol [online]. 2013, vol.26, n.1, pp. 99-110. ISSN 0864-2176.

Objective: to analyze the corneal endothelium behavior in patients undergoing sequential vitreous and cataract surgery. Methods: a prospective, descriptive and observational study of 15 patients (eyes) with several vitreous and lens surgeries at the "Ramón Pando Ferrer" Cuban Institute of Ophthalmology from January through November 2010. Results: most of the patients were males whose ages ranged 53 to 67 years. The main causes for indicating pars plana vitrectomy were retinal detachment and vitreous hemorrhage. Pre and postoperative cellular density averages in this group showed a cellular loss of 17.2 %. In the preoperative exam, lack of polymegatism in its mildest forms predominated, whereas moderate and severe forms increased in the postoperative phase. Pleomorfism behaved in a similar way. Postsurgical complications found were ocular hypertension,anterior segment toxic syndrome and anterior uveitis, with 9 cases at the two surgical periods. Conclusions: the corneal endothelium suffers both anatomical and functional changes after pars plana vitrectomy, which may be remarkable after a second surgery, even more if this occurs in the anterior segment such as the cataract extraction using phacoemulsification.

Palabras clave : endothelial microscopy; vitrectomy; sequential surgery; phacoemulsification.
