HERNANDEZ SILVA, Juan Raúl et al. Confocal microscopy of the cornea on phacoemulsification. Rev Cubana Oftalmol [online]. 2011, vol.24, n.2, pp. 220-229. ISSN 0864-2176.

Objective: To determine the structural changes in the cornea in the cataract surgery using phacoemulsification without complications. Methods: A prospective study of patients operated on from cataract using the coaxial phacoemulsification (Pre Chop) technique without complications was carried out. These patients also underwent confocal microscopy of the cornea with Confoscan4 (Nidek Technologies) with 40x target and Z - Ring adapter. The study was performed in the preoperative period and postoperative period for 24 hours, one week, one month and three months after surgery. Results: Structural changes were observed in the cornea such as epithelial cells with hypereflectivity nucleus, occasionally elongated, , areas of anomalous hypereflectivity 24 hours after surgery. Activated Keratocytes persisted as well as decreased hypereflectivity of the extracellular matrix that disappeared after a month. Conclusions: Although biomicroscopy did not show corneal alterations in the postoperative period of the cataract surgery using phacoemulsification, these can be observed in confocal microscopy of the cornea. These variations do not have an impact on optimal visual recovery of the patients.
