【 摘 要 】
References(28)This study was performed to evaluate changes in intraocular pressure (IOP) duringstandard coaxial phacoemulsification using 4 different bottle heights (BHs) and 2different incision sizes. Coaxial phacoemulsification was performed with a venturi-basedmachine in 8 enucleated canine eyes through 3.0 and 3.2 mm clear corneal incisions (CCIs).A pressure transducer inserted in the peripheral cornea monitored the IOP in real-time.The surgery was subdivided into 4 stages: sculpt-segment removal, irrigation/aspiration,capsular polishing and viscoelastic removal. The mean IOP and the difference between themaximum and minimum IOPs were calculated at each stage and compared. The ultrasound timeand volume of irrigation fluid used were recorded. The mean IOP increased with anelevation in the BH. The mean IOP in the irrigation/aspiration stage was significantlyhigher than that in the sculpt-segment removal stage at the same BH. The differencebetween the maximum and minimum IOP at each stage was greater in the 3.2 mm than the 3.0mm CCIs, although the mean IOP was lower with the 3.2 mm than the 3.0 mm CCIs. Theultrasound time and irrigation fluid volume were greater with the 3.2 mm than the 3.0 mmCCIs. Therefore, fluidic parameters during each stage could be reassessed and adjusted toreduce complications arising from an elevated IOP. Phacoemulsification with 3.0 mm CCIs ata lower BH might lead to less stress on the eye from IOP fluctuations, ultrasound energyand irrigation fluid.
