ABSTRACT
Objective: to determine the impact of the application of the techniques of prechop vs phacochop techniques on the corneal endothelium in the cataract surgery using phacoemulsification.Methods: a prospective, analytical case-control study in the cataract service of the Center of Ocular Microsurgery Ocular in "Ramón Pando Ferrer" teaching ophthalmological hospital, with the diagnosis of unilateral or bilateral cataract, and conducted from January 2013 to January 2014. Fifty patients underwent the prechop procedure and 50 were applied the phacochop method. The variables under study were age, sex, crystalline lens hardness and length of time of ultrasound application; both in the preoperative and postoperative phase, the cell density, hexagonality and the coefficient of variability were took into account.
Results: when comparing the postoperative results in the prechop group with those of the phacochop one, there were differences in the loss of cell density and hexagonality, being greater in the phacochop group. There were also differences in the coefficient of variability, and the effective time of phacoemulsificación, which were greater in the phacochop group.
Conclusions: the postoperative results corroborate that the group of patients under prechop procedure has better preservation of their corneal endothelium than those in the phacochop group.
