【摘要】：目的:觀察飛秒激光輔助白內(nèi)障超聲乳化手術(shù)中2.2mm透明角膜切口引起的術(shù)源性散光(SIA)影響因素。方法:前瞻性研究。納入2014年3月至2016年4月期間,在山西省眼科醫(yī)院白內(nèi)障一科行飛秒激光輔助下白內(nèi)障超聲乳化手術(shù)的患者84例(105眼),測量并記錄患者術(shù)前,術(shù)后1個(gè)月、3個(gè)月、6個(gè)月的裸眼視力(UCVA),球鏡度和角膜地形圖數(shù)據(jù)。視力記錄為log MAR視力,使用Alpins矢量分析法計(jì)算SIA。并從術(shù)后隨訪時(shí)間(術(shù)后1、3、6個(gè)月3個(gè)時(shí)間點(diǎn))、晶狀體核硬度(分Ⅱ、Ⅲ、Ⅳ級核3組)、角膜散光類型(分順規(guī)、逆規(guī)、斜軸組3組)、眼別(左眼、右眼組2組)4個(gè)方面分析SIA。符合正態(tài)性分布的數(shù)據(jù)的比較使用重復(fù)測量的方差分析,以P0.05為差異有統(tǒng)計(jì)學(xué)意義。結(jié)果:84例(105眼)患者UCVA術(shù)前為0.65±0.24,術(shù)后1、3、6個(gè)月為0.07±0.02、0.06±0.01、0.06±0.01。手術(shù)前后比較差異有統(tǒng)計(jì)學(xué)意義;術(shù)后各時(shí)間點(diǎn)比較差異無統(tǒng)計(jì)學(xué)意義。術(shù)后1、3、6個(gè)月SIA分別為0.28±0.11D、0.25±0.13D、0.24±0.10D;3個(gè)時(shí)間點(diǎn)比較差異無統(tǒng)計(jì)學(xué)意義。按晶狀體核硬度分組從時(shí)間上及組別間比較均無統(tǒng)計(jì)學(xué)意義;順規(guī)組、逆規(guī)組、斜軸組3組從時(shí)間上及組別間比較差異均無統(tǒng)計(jì)學(xué)意義;右眼組與左眼組從時(shí)間上及組別間比較差異均無統(tǒng)計(jì)學(xué)意義。結(jié)論:2.2mm角膜切口飛秒激光輔助白內(nèi)障超聲乳化手術(shù)能夠提供穩(wěn)定的術(shù)源性散光,同時(shí)顯著提高患者術(shù)后裸眼視力,且術(shù)源性散光與裸眼視力自術(shù)后1個(gè)月起保持穩(wěn)定。
[Abstract]:Aim: to observe the influencing factors of surgical astigmatism induced by 2.2mm transparent corneal incision in femtosecond laser assisted phacoemulsification. Methods: prospective study. From March 2014 to April 2016, 84 patients with phacoemulsification underwent femtosecond laser assisted phacoemulsification in Department of Cataract, Shanxi Ophthalmology Hospital. 1 month, 3 months and 6 months after operation, the uncorrected visual acuity (UCVA), ball endoscopy and corneal topography were observed. Visual acuity was recorded as log MAR, and Alpins vector analysis was used to calculate the visual acuity. SIAs were analyzed from four aspects: postoperative follow-up time (1: 3, 6 months), hardness of lens nucleus (divided into 鈪，
