摘　　要：目的探讨白内障超声乳化(超乳)手术对不同体位(包括坐位、仰卧位、侧卧位)眼压的影响。方法选取未合并青光眼且计划一眼行白内障超乳联合人工晶状体植入术的患者30例。于手术前及手术后1个月采用Tono-Pen AVIA眼压计分别测量坐位、仰卧和侧卧(手术眼位于下方)位置的眼压。不同体位保持15 min后按坐位、仰卧位、侧卧位顺序测量眼压,每次间隔15 min,测量3次取平均值。采用两因素重复测量方差分析不同体位的眼压变化。结果白内障超乳术后不同体位眼压均低于术前眼压,手术眼术后坐位、仰卧位、侧卧位的平均眼压均低于术前[(13.1±2.1)mmHg vs(14.6±1.5)mmHg,P=0.028;(14.9±1.8)mmHg vs(16.6±2.1)mmHg,P=0.002;(16.5±2.1)mmHg vs(19.5±3.1)mmHg,P=0.001]。坐位、仰卧位和侧卧位的手术眼平均眼压分别降低(0.7±2.1),(1.8±2.2)和(3.2±3.1)mmHg(坐位vs仰卧,P=0.043;坐位vs侧卧位,P=0.001;仰卧位vs侧卧位,P=0.027)。非手术眼术后眼压比较,差别无统计学意义(均P>0.05)。结论白内障超乳手术降低坐位、仰卧位和侧卧位的眼压,且卧位眼压较坐位眼压降低更明显。Objective To investigate the effect of phacoemulsification on intraocular pressure(IOP)in different positions including sitting,supine and lateral decubitus(LD)positions.Methods Thirty patients without glaucoma who planned to undergo phacoemulsification combined with intraocular lens implantation in one eye were selected.The Tono-Pen AVIA tonometer was used to measure the IOP in the sitting,supine position and LD(the operation eye is below)before the operation and 1 month after the operation.IOP was measured 15 min after assuming each position,and the average value of the measurements was taken 3 times.Two-factor repeated measures analysis of variance was used to compare the IOP changes before and 1 month after phacoemulsification in all postures.Results The postoperative IOP was lower than the preoperative IOP for the sitting,supine and LD positions[(13.1±2.1)mmHg vs(14.6±1.5)mmHg,P=0.028;(14.9±1.8)mmHg vs(16.6±2.1)mmHg,P=0.002;(16.5±2.1)mmHg vs(19.5±3.1)mmHg,P=0.001].The average IOP reduction of the operated eye was(0.7±2.1)mmHg,(1.8±2.2)mmHg,and(3.2±3.1)mmHg in the sitting,supine,and LD positions,respectively(sitting vs supine,P=0.043;sitting vs LD,P=0.001;supine vs LD,P=0.027).In the nonoperated eye,IOP did not change significantly after surgery(all P>0.05).Conclusions Cataract surgery lowered IOP in the sitting position as well as in the supine and LD positions.Especially postoperative IOP reductions were greater in the recumbent positions than in the sitting position.
