【Abstract】 Objective To estimate the method and effect of the phacoemulsification and foldable intraocular lens implantation through a small clear corneal incision. Methods 138 cases of patients (168?eyes)with cataract includes the senile cataract.Complicated cataract,and traumatic cataract were operated with phacoemulsification and foldable IOL implantation through a clear corneal incision under topical anaesthesia.The visual acuity and the complications were observed postoperatively. Results Postoperatively,the uncorrected visual acuity was 0 4 in 157?eyes(93 45%) on d?1.The corrected visual acuity 0 5 or better after the first week and first month were achieved in 152?eyes(90 48%) and 160?eyes(95 24%),respectively.The inflammatory reaction after operation was associated with the hardness of the nuclei,the time and the power of phaco. Conclusion Phacoemulsification with foldable lens implantation through a clear corneal incision under the topical anaesthesia was a safe and effective method for the treatment of the cataract.The advantages and the technique of the topical anaesthesia used during the phacoemulsification was discussed in detail.更多还原
