23G前段玻璃體切割術(shù)在淺前房低角膜內(nèi)皮細(xì)胞密度白內(nèi)障手術(shù)中的應(yīng)用
[Abstract]:Objective to evaluate the efficacy and safety of 23 G anterior vitrectomy combined with phacoemulsification in the treatment of low corneal endothelial cell density (endothelial cell density,ECD) cataract in shallow anterior chamber. Methods from January 2012 to December 2015, 30 patients (34 eyes) with shallow anterior chamber cataract with ECD1000 mm-2 received surgical treatment from January 2012 to December 2015 in the second affiliated Hospital of Zhengzhou University were divided into combined operation group and Phaco group. 16 cases (19 eyes) in combined operation group were treated with 23 G anterior vitrectomy combined with phacoemulsification, and 14 cases (15 eyes) in Phaco group were treated with phacoemulsification. The best corrected visual acuity (BCVA) and corneal edema degree were examined 1 week and 3 months after operation. The time of corneal edema regression, intraoperative and postoperative complications were recorded by ECD, before and 3 months after operation. Results on the 1st day after operation, the best corrected visual acuity in the combined operation group was significantly higher than that in the preoperative group (P0.05). At 1 week and 3 months after operation, the best corrected visual acuity (BCVA) in both groups was significantly higher than that before operation (P0.05). The best corrected visual acuity of the combined operation group was better than that of the Phaco group on the 1st day and 1 week after operation, and the difference was statistically significant (P0.05). One day after operation, the corneal edema was mainly grade 1 in the combined operation group and the second grade in the Phaco group. There was significant difference in the degree of corneal edema between the two groups (P0.05). The mean extinction time of corneal edema in the combined operation group was 1.0 days, which was less than that in the Phaco group (P 0.05). The loss rate of corneal endothelial cells in the combined operation group was (7.86 鹵0.76)%, lower than that in the Phaco group (13.39 鹵0.47)%, the difference was statistically significant (P0.05). Conclusion 23 G anterior vitrectomy combined with phacoemulsification is safe, with little corneal endothelial cell damage, slight corneal edema and rapid recovery of early visual acuity. It is suitable for patients with shallow anterior chamber and low ECD cataract.
