To determine whether exposing the extraocular muscles (EOMs) to lidocaine via retrobulbar injection for cataract surgery has a demonstrable negative effect on subsequent function of the muscle.
York Finch Eye Associates, Humber River Regional Hospital, and Toronto Western Hospital Research Institute, Toronto, Ontario, Canada.
This study comprised 37 eyes that had phacoemulsification and posterior chamber intraocular lens implantation; 13 eyes had retrobulbar lidocaine with hyaluronidase and 24 eyes, topical anesthesia. The postoperative saccadic velocities were compared with the preoperative velocities using a sensitive recording device. The results were compared within and between the retrobulbar lidocaine and topical anesthesia groups.
No detectable decrement in postoperative saccadic velocities was detected in any patient, and no difference was found between the groups.
Exposing EOMs to lidocaine for cataract surgery had no detectable negative effect on saccadic velocities 1 week after surgery.
确定在白内障手术中通过球后注射将利多卡因暴露于眼外肌（EOMs）是否会对肌肉的后续功能产生明显的负面影响。
加拿大多伦多安大略省约克芬奇眼科协会、亨伯河地区医院和多伦多西部医院研究所。
本研究包括37只接受了超声乳化白内障吸除术和后房型人工晶状体植入术的眼睛；13只眼睛接受了含透明质酸酶的球后利多卡因注射，24只眼睛接受了表面麻醉。使用灵敏的记录设备将术后扫视速度与术前速度进行比较。对球后利多卡因组和表面麻醉组内部及两组之间的结果进行了比较。
在任何患者中均未检测到术后扫视速度有可检测到的下降，且两组之间未发现差异。
在白内障手术中将眼外肌暴露于利多卡因对术后1周的扫视速度没有可检测到的负面影响。
