Malposiciones palpebrales y su influencia en la topografía corneal previa y posterior a la corrección quirúrgica de pacientes atendidos en el Hospital Militar Central

Introduction: palpebral malpositions (ptosis, upper dermatochalasis and ectropion) are the main reasons for consultation in the area of eye plastic surgery. There is still no conclusive information in the literature on the topographic corneal changes that are generated with palpebral malpositions and if there are changes in the corneal topography after surgical correction. Objective: to determine the topographic corneal changes of patients with palpebral malpositions submitted to surgical correction. Study design: longitudinal prospective observational study. Methods: Patients selected for convenience who underwent surgical correction of palpebral conditions (ptosis, ectropion and upper dermatochalasis) at the Central Militar Hospital of Bogota between April and September 2019. Corneal topography data prior to correction were described. and one month and three months after this and the visual acuity better corrected preoperatively and in the last postoperative evaluation performed. Results: surgical correction of palpebral malpositions was performed in 106 eyes of 54 patients. The middle cylinder had a change of 0,13 D and the displacement of the cylinder axis of 1,49 °. The average global change in mean keratometry was 0,01 D and the central corneal thickness decreased 1,5 mcs. With the best corrected visual acuity there was an increase of 0,0415 per LogMAR scale. Conclusion: palpebral malpositions surgery generates corneal topographic changes, where the correction of ptosis is the one that causes the most changes, with persistence of the changes at 3 months postoperatively.
