Aesthesiometry after Cryo-keratomileusis and in situ Keratomileusis

Objective: Evaluation of corneal reinnervation after cryo-keratomileusis and keratomileusis. Study Design: Retrospective evaluation of corneal sensitivity after cryo-keratomileusis and in situ keratomileusis. The measurements were performed with the Draeger electromechanical optical-controlled aesthesiometer, which is very precise and independent of external changes in temperature and humidity. Three measuring points were on the lenticle and 2 at approximately 1 mm distance from the limbus. Setting: Instituto Barraquer, Bogota, Columbia (South America). Patients: Twelve patients after cryo-keratomileusis and 38 patients after in situ keratomileusis. Results: It was shown that the recovery of corneal sensitivity after cryo-keratomileusis is delayed due to the depth of the keratectomy and freezing procedure compared to in situ keratomileusis.
