Objective To evaluate the effectiveness of acupunctural analgesia as an anesthetic method in cataract surgery using the Blumenthal technique. Methods Fifty patients who underwent cataract surgery using the Blumenthal technique from January to December 2005 in the Miguel Enriquez University Hospital were selected. All information gathered, including the operational variables of age, sex, race, hemodynamic and/or systemic alterations, and the need to change the technique to evaluate effectiveness and ocular or systemic complications were introduced into a database. The results were processed by the SPSS statistical software package, version 11.5, through a Pentium Dual-Core computer with the Windows Xp operating system programs Microsoft Office Excel and Microsoft Office Word to design the text. Frequency tables and graphics for the distinct variables were constructed. Summary measures, such as absolute values and percentages, were used. The non-parametric method of Pearsońs Chi-squared test of independence and statistical homogeneity was applied, with a permissible error of 5%. Results There were no systemic or hemodynamic alterations in the course of the surgery. The analgesic method was changed to intracameral injection of preservative-free lidocaine in only one patient. Postoperative complications were not attributable to the type of anesthesia and consisted of mild corneal edema and secondary ocular hypertension. Conclusions Acupunctural analgesia is an alternative technique in cataract surgery.
