Hypromellose can be used as a viscoelastic substance during cataract surgery. Two groups of patients, one group operated on using hypromellose, the other using sodium hyaluronate as a viscoelastic substance were followed up 2-6 months postoperatively. A total of 16.7% of the eyes operated on using hypromellose developed a non-reactive semidilated pupil whereas none of the eyes from the control group developed this phenomenon. It was concluded that there is a probable link between the intraocular use of hypromellose and abnormal pupils after cataract surgery.
羟丙甲纤维素可在白内障手术中用作粘弹性物质。两组患者,一组使用羟丙甲纤维素进行手术,另一组使用透明质酸钠作为粘弹性物质,术后随访2至6个月。使用羟丙甲纤维素进行手术的眼睛中有16.7%出现了无反应性半散瞳,而对照组的眼睛均未出现这种现象。得出的结论是,白内障手术后眼内使用羟丙甲纤维素与瞳孔异常之间可能存在联系。
