Abstract
Objective: To evaluate the effect of topical anesthesia for extracapsular cataract extraction and posterior chamber lens implantation. Methods: 92 eyes of 87 cases were selected randomly to carry out the extracapsular cataract extraction and intraocular lens implantation in topical anesthesia. Results: 83 eyes (90.2%) were satisfied, 89 eyes (96.7%) were effective. Whereas posterior capsular was damaged and vitreous body was loss in 3 eyes (3.3%) and the operations were finished in retrobulbar anesthesia. The rate about the damage of posterior capsular and loss of vitreous body were lower than those of peri-bulbar anesthesia simultaneously. The reason was probably that the cases were cautiously selected to finfish the first extracapsular cataract extraction in topical anesthesia. Conclusion: The topical anesthesia for extracapsular cataract extraction and intraocular lens implantation might be a safe, effective and convenient method.
