目的评估双手微切口超声乳化及Acri.smart人工晶体植入术的安全性、有效性。方法对22例(27眼)老年性白内障患者行双手微切口超声乳化术,植入Acri.smart人工晶体。观察患者术后视力、超声乳化时间、角膜内皮丢失率、散光变化及手术并发症。结果术后1周、1月、3月裸眼视力≥0.5的患者所占比例分别为85.2%,92.6%,96.3%,术后3个月矫正视力≥0.8为82.5%。平均有效乳化时间(EPT)为(4.8±3.13)sec,平均乳化能量为(13.6±7.32)%。角膜内皮丢失率为14.95%,术后1周和1月的散光分别为(0.72±0.35)D,(0.77±0.37)D。所有患者术中均切口密闭,前房稳定,未出现角膜灼伤等并发症。2例早期患者术中出现晶体断裂。结论双手微切口超声乳化及Acri.smart人工晶体植入术是安全有效的,可以通过1.2mm微切口实现白内障手术。
Objective To evaluate the safety and effectiveness of micromanipulation with phacoemulsification and Acri.smart intraocular lens implantation. Methods Twenty-two patients (27 eyes) with senile cataract underwent both-hand micro-incision phacoemulsification and implantation of Acri.smart intraocular lens. The postoperative visual acuity, phacoemulsification time, corneal endothelial loss, astigmatism and surgical complications were observed. Results The percentages of patients with uncorrected visual acuity ≥0.5 at 1 week, 1 month and 3 months after operation were 85.2%, 92.6% and 96.3% respectively. The corrected visual acuity ≥ 0.8 at 3 months after operation was 82.5%. The mean effective emulsification time (EPT) was (4.8 ± 3.13) sec and the average emulsified energy was (13.6 ± 7.32)%. The corneal endothelial loss rate was 14.95%. The astigmatism was (0.72 ± 0.35) D and (0.77 ± 0.37) D at 1 week and January respectively. All patients were incision airtight surgery, anterior chamber stability, no corneal burns and other complications. Two cases of early patients with intraocular lens fracture. Conclusions Two-hand micro-incision phacoemulsification and Acri.smart intraocular lens implantation are safe and effective, and cataract surgery can be achieved through 1.2mm micro-incision.
