ABSTRACT

Objective: To describe the results of the application of cryoanalgesia in the cataract surgery using simultaneous bilateral phacoemulsification in patients with a history of allergic reactions to pharmacological anesthesics.
Methods: A descriptive case series study was performed in 10 patients with histories of allergic reactions to pharmacological anesthetics that are used in the cataract surgery. All these patients underwent Prechop technique-based simultaneous bilateral phacoemulsification through temporal clear cornea, with irrigation of balanced saline solution and viscoelastic substances at 4 °C in the Center of Ocular Microsurgery of "Ramon Pando Ferrer" Cuban Institute of Ophthalmology.
Results: No differences were found between sexes; the average age was 62.3 years; the crystalline lens hardness, according to LOCS III mostly presented with nuclear opacities ranging II to IV; the effective ultrasound time did not exceed half a minute. All these patients recovered their best corrected visual acuity and no complications were reported. The endothelial cell count showed a loss of 3.5 % when compared with the preoperative initial count.
Conclusions: Cryoanalgesia in phacoemulsification, with the use of refined surgical technique by experienced surgeons, is safe and effective with visual results similar to those achieved in patients operated on of cataract through phacoemulsification with pharmacological anesthetic.
