The Influence of the Type of Viscoelastic Substances on the Level of Intraocular Pressure after Phacoemulsification The aim of study was to asses the influence of the type of viscoelastic substances on the level of intraocular pressure (IOP) after cataract surgery and intraocular lens (IOL) implantation. In the study group of 100 patients Viscoat was used at 32 operated eyes, Provisc at 14 eyes and Duovisc in 54 eyes during phacoemulsification and IOL implantation. IOP was measured before surgery, one day after surgery and one week after surgery. Mean IOP level 1. day postoperatively was 24.94 mmHg in the Viscoat group of eyes, 24.65 mmHg in the Provisc group and 21.09 mmHg in the Duovisc group. The type of viscoelastic substance used during the surgery significantly influenced the level of IOP in the first postoperative day. The level of IOP was significantly lower in the Duovisc group comparing to Viscoat and Provisc. The level of IOP did not differ significantly between the Viscoat and Provisc group. One week after surgery the level of IOP was not significantly different between all types of viscoelastic device. Duovisc was the most profitable viscoleastic substance in the point of view of the course of phacoemulsification, IOL implantation and postoperative level of IOP.
黏弹剂类型对白内障超声乳化术后眼压水平的影响 本研究的目的是评估黏弹剂类型对白内障手术及人工晶状体（IOL）植入术后眼压（IOP）水平的影响。在100例患者的研究组中，32只手术眼在白内障超声乳化及IOL植入术中使用了Viscoat，14只眼使用了Provisc，54只眼使用了Duovisc。在手术前、术后1天及术后1周测量眼压。Viscoat组术后第1天的平均眼压水平为24.94 mmHg，Provisc组为24.65 mmHg，Duovisc组为21.09 mmHg。手术中使用的黏弹剂类型在术后第1天对眼压水平有显著影响。与Viscoat和Provisc相比，Duovisc组的眼压水平显著更低。Viscoat组和Provisc组之间的眼压水平无显著差异。术后1周，所有类型的黏弹剂装置之间的眼压水平无显著差异。从白内障超声乳化、IOL植入过程及术后眼压水平来看，Duovisc是最有益的黏弹剂。
