目的 分析短眼轴性白内障超声乳化吸除术的难点 ,并探讨其预防措施。方法 对行超声乳化白内障吸除手术、眼轴长度为 2 0 2 1～ 2 2 10mm的白内障患者 12 2例 (143只眼 )进行回顾性分析。结果 术后 1个月矫正视力 1 0～ 1 2者占 16 8%,0 5～ 0 8者占 6 7 1%;术中晶状体后囊膜破裂发生率为 7 7%;术后炎性反应明显 ,角膜可逆性水肿发生率为 2 9 4 %,明显高于长眼轴白内障患者 (6 7%) ,高于正常眼轴硬核性白内障患者 (12 5 %)。结论 短眼轴性白内障患者前房浅、眼前段组织空间狭小、玻璃体压力高 ,手术难度大 ;强调切口规范 ,应用手法碎核技术和低能量、高吸引力超声乳化技术 ,提高超声乳化操作的有效性 ,使用高质量黏弹剂 ,保持前房深度 ,均是顺利完成手术的关键。
Objective To analyze the operative difficulty of cataract phacoemulsification in an eye with shorter axial length and discuss its preventive measures. Methods A retrospective study was performed to analyze the 122 patients (143 eyes) who had undergone cataract phacomulsification. Their ocular axial lengths were 20.21 to 22.10 mm. Results Because these patients had shorter ocular axis, shallower anterior chamber depth, narrower space in the anterior ocular segment and higher vitreous pressure, the operation was hard to perform. The rate of posterior capsular rupture was 7.69%. The postoperative inflammatory reaction was severe. The rate of reversible corneal edema (29.37%) was obviously higher than that in cataractous eyes with normal ocular axis (6.7%, P<0.01), and also higher than that in eyes with normal ocular axis and hard nucleus (12.5%, P<0.05). Conclusions It is emphasized that the correct technique of incision, application of chopping and breaking nucleus technique, lower energy and higher aspiration for effective phacoemulsification with the help of Viscoat viscoelastic material and maintenance of deep anterior chamber are the key procedures to obtain satisfactory operative results.
