[Phacoemulsification aspiration and intraocular lens implantation].

OBJECTIVE: To investigate the characteristics of phacoemulsification of cataract in our country and management and prevention of its complications. METHODS: The procedure of phacoemulsification with small incision (6 mm) intraocular lens implantation was improved and was performed on 40 eyes of 40 cases. They had been followed up for 3-6 months postoperatively and their follow-up results were summarized. RESULTS: The uncorrected visual acuity 1.0 or better was in 57.5%, 0.8 or better in 82.5% and 0.5 or better in 97.5%. The postoperative mean astigmatism was 0.50 +/- 0.25 D, which was less than that in the large incision group (9-12 mm) performed on 40 cases in the same period (P < 0.001). Cataract with hard nucleus can be successfully taken out by the technique of peripheral rotation engraving method. CONCLUSION: The operation is a safe reliable one for restoration of visual acuity in patients with cataract, and is superior to extracapsular cataract extraction.
