摘　　要：目的探讨超声乳化白内障摘除及人工晶体植入术后早期的眼压变化。方法对４９例（５３只眼）白内障患者进行手术前及术后定期眼压测量。结果发现无论术毕对切口缝合与否，术后１０～１２小时眼压均较术前明显升高；缝合切口组眼压的升高程度明显高于不缝合切口组（ｔ分别为４．４１和３．３２，Ｐ分别为０．０００１和０．００２０）。术后１６只眼眼压＞３．００ｋＰａ（１ｋＰａ＝７．５ｍｍＨｇ），其中缝合切口组１０只眼（１０／２０，５０．０％），不缝合切口组６只眼（６／３３，１８．２％），两组间的差异有显著性（χ２＝５．９８２０，Ｐ＝０．０１４）。术后２２～２４小时眼压已明显降低，４６～４８小时已降至术前水平。结论超声乳化白内障摘除及人工晶体植入术后早期眼压有不同程度升高，缝合切口者眼压升高更为显著，应于术后注意测量眼压，以便及时作相应处理，提高手术疗效。Objective To investigate intraocular pressure (IOP) changes early after phacoemulsification with posterior chamber lens implantation. Methods The IOP was measured in 49 patients 53 eyes before and 10～12, 22～24, 46～48 hours after the operation. Results The IOP increased obviously in all eyes 10～12 hours after the operation, and rose more significantly from the baseline to the maximum 10～12 hours after surgery in 20 sutured eyes than that in 33 unsutured eyes (t=4.41 and 3.32, P=0.000 1 and 0.002 0, respectively). It was higher than 3 kPa in 16 eyes, 10 (10/20, 50.0%) in the sutured group, 6 (6/33, 18.2%) in the unsutured group, respectively, and the difference was significant between the two groups (χ2=5.982 0, P=0.014). The IOP decreased markedly 22～24 hours, and returned to the baseline level 46～48 hours after the operation. Conclusion These results indicate that IOP increases early after phacoemulsification with posterior chamber lens implantation, especially in sutured eyes. Therefore, to apply corresponding management properly in time and obtain better therapeutic effects of the operation, IOP should be measured regularly.
