结论:有证据表明,白内障手术可以降低原发性开放角度患者的眼压。正常张力-,或剥脱性青光眼。白内障超声乳化术的完全效果被局部眼内压降低药物掩盖。
目的:评估白内障超声乳化和人工晶状体植入术对原发性开角型青光眼(POAG)患者眼压(IOP)水平的影响,剥脱性青光眼(XFG),剥脱综合征(XFS),正常眼压性青光眼(NTG),手术后12个月的高眼压(OH)或健康对照。
方法:2023年7月,对六个数据库进行了全面的文献综述。分析重点是随机对照试验(RCT)的超声乳化术。感兴趣的主要结果是超声乳化术后12个月观察到的平均IOP变化。
结果:这项荟萃分析包括来自9个RCT的9组,共有502名参与者。总的来说,术后12个月,平均IOP降低3.77mmHg(95CI:-5.55~-1.99,I2=67.9%).亚组分析,关注在测量IOP之前是否使用了冲洗期,显示有冲洗期的研究显示出更明显的眼压降低5.25mmHg(95CI:-7.35至-3.15,I2=0%),而无冲洗期的研究显示降低了3.13mmHg(95CI:-5.46至-0.81,I2=75.8%)。对后一组的敏感性分析,不包括离群值研究,显示降低1.81mmHg(95CI:-2.95至-0.67,I2=0%)。
结论:本系统综述和荟萃分析的结果表明,白内障手术有意义地降低POAG患者的眼压,XFG/XFS,或OH手术后12个月。然而,局部用药掩盖了超声乳化术对术后IOP的确切影响.有必要使用适当的冲洗期进行进一步的研究。
CONCLUSIONS: There is evidence that cataract surgery can reduce intraocular pressure in patients with primary open angle, normal tension, or exfoliative glaucoma. The complete effect of phacoemulsification is masked by topical intraocular pressure-lowering medications.
OBJECTIVE: To assess the impact of phacoemulsification and intraocular lens implantation on intraocular pressure (IOP) level in individuals with primary open angle glaucoma (POAG), exfoliative glaucoma (XFG), exfoliation syndrome (XFS), normal tension glaucoma (NTG), ocular hypertension (OH), or healthy controls 12 months after the surgery.
METHODS: In July 2023, a comprehensive literature
review was conducted across six databases. The analysis focused on the phacoemulsification arms of randomized controlled trials (RCTs). The primary outcome of interest was the mean IOP change observed 12 months after phacoemulsification.
RESULTS: This meta-analysis included 9 arms from 9 RCTs, comprising a total of 502 participants. Overall, the average IOP was reduced by 3.77 mm Hg (95% CI: -5.55 to -1.99, I2 =67.9%) 12 months after surgery. The subgroup analysis, focused on whether a washout period was used before measuring IOP, revealed that studies with a washout period exhibited a more pronounced IOP reduction of 5.25 mm Hg (95% CI: -7.35 to -3.15, I2 =0%), while studies without a washout period exhibited a reduction of 3.13 mm Hg (95% CI: -5.46 to -0.81, I2 =75.8%). The sensitivity analysis for the latter group, excluding an outlier study, showed a reduction of 1.81 mm Hg (95% CI: -2.95 to -0.67, I2 =0%).
CONCLUSIONS: The findings of this systematic
review and meta-analysis indicate that cataract surgery meaningfully lowers IOP in POAG, XFG/XFS, or OH 12 months after surgery. However, the use of topical medications masks the precise impact of phacoemulsification upon postoperative IOP. Further research using appropriate washout periods is warranted.
