目的探讨影响晶状体超声乳化吸出术后早期眼压变化的相关因素及临床意义。方法120例(136眼)行晶状体超声乳化吸出联合人工晶状体植入术,测量术前、术后24h和72h的眼压,比较不同麻醉方式(表面麻醉、球后浸润麻醉)、不同手术切口(巩膜切口、透明角膜切口)、术后口服皮质类固醇与否对术后早期眼压变化的影响。结果术后24h眼压较术前高,72h基本达到术前或略低于术前眼压。晶状体超声乳化术的麻醉方式和术后是否使用皮质类固醇与术后早期眼压变化具有相关性,相关系数分别为0.187和0.280(P<0.014和P<0.001)。球后浸润麻醉的术后眼压较表面麻醉的眼压相对增高;术后不用皮质类固醇比用皮质类固醇眼压相对增高。不同手术切口对术后早期眼压变化则无相关性。结论表面麻醉和术后口服皮质类固醇对白内障超声乳化术后早期眼压的影响较小。
Objective To investigate the related factors and clinical significance of early intraocular pressure (IOP) changes after phacoemulsification. Methods 120 patients (136 eyes) underwent phacoemulsification and intraocular lens implantation. The intraocular pressure (IOP) at preoperative and postoperative 24h and 72h were measured. The changes of intraocular pressure (I / R) Scleral incision, clear corneal incision), postoperative oral corticosteroids or postoperative IOP changes. Results Intraocular pressure was higher than preoperative 24 h after operation, and reached preoperative or slightly lower preoperative intraocular pressure at 72 h. The phacoemulsification phacoemulsification and whether postoperative use of corticosteroids and postoperative IOP were correlated with correlation coefficients of 0.187 and 0.280 (P <0.014 and P <0.001, respectively). Post-opthalmal anesthesia postoperative intraocular pressure than the surface anesthesia intraocular pressure relatively higher; postoperative corticosteroids than corticosteroid intraocular pressure was relatively higher. Different surgical incision postoperative IOP no correlation. Conclusion The effects of topical anesthesia and postoperative oral corticosteroids on IOP after cataract phacoemulsification are small.
