Abstract

Purpose: To compare vision quality following phacoemulsification cataract extraction and implantation of a Big Bag or Akreos Adapt intraocular lens (IOL) in patients diagnosed with high myopia complicated with cataract.

Methods: This was a randomized prospective control study. The patients with high myopia. complicated with cataract, with axial length ≥ 28 mm, and corneal astigmatism ≤ 1D were enrolled and randomly divided into the Big Bag and Akreos Adapt IOL groups. All patients underwent phacoemulsification cataract extraction and lens implantation. At 3 months after surgery, intraocular high-order aberration was measured by a Tracey-iTrace wavefront aberrometer at a pupil diameter of 5 mm in an absolutely dark room and statistically compared between two groups. The images of the anterior segment of eyes were photographed with a Scheimpflug camera using Penta-cam three-dimensional anterior segment analyzer. The tilt and decentration of the IOL were calculated by Image-pro plus 6.0 imaging analysis software and statistically compared between two groups.

Results: In total, 127 patients (127 eyes), including 52 males and 75 females, were enrolled in this study. The total high-order aberration and coma in the Akreos Adapt group (59 eyes) were significantly higher compared with those in the Big Bag (P < 0.05). The clover and spherical aberration did not differ between the two groups (P > 0.05). The horizontal and vertical decentration were significantly smaller in the Big Bag lens group than in the Akreos Adapt group (both P < 0.05), whereas the tilt of IOL did not significantly differ between the two groups (P > 0.05).

Conclusion: Both Big Bag and Akreos Adapt IOLs possess relatively good intraocular stability implanted in patients with high myopia. Compared with the Akreos Adapt IOL, the Big Bag IOL presents with smaller intraocular high-order aberration. Coma is the major difference between the two groups.

高度近视眼植入术后大袋型与Akreos型人工晶状体视力质量的比较。

目的:比较高度近视合并白内障患者超声乳化白内障摘出与植入术后的视力质量。方法:随机前瞻性对照研究。高度近视患者。纳入眼球轴长≥28 mm、角膜散光≤1D的合并白内障患者，随机分为Big Bag组和Akreos adaptive IOL组。所有患者均行超声乳化术、白内障摘除及晶状体植入术。术后3个月，在绝对黑暗的房间内，用Tracey-iTrace波前像差仪测量瞳孔直径为5mm的眼内高阶像差，并进行统计学比较。采用五凸轮三维眼前段分析仪，采用Scheimpflug相机拍摄眼前段图像。采用Image-pro plus 6.0影像分析软件计算人工晶状体的倾斜度和离体度，并对两组进行统计学比较。结果:共纳入患者127例(127只眼)，其中男性52例，女性75例。Akreos Adapt组总高阶像差和昏迷数(59眼)明显高于Big Bag组(P < 0.05)。三叶草和球差在两组间无显著差异(P > 0.05)。与Akreos Adapt组相比，Big Bag组的水平和垂直晶状体离体明显减小(P < 0.05)，而IOL的倾斜度两组间差异无统计学意义(P > 0.05)。结论:大袋人工晶体与Akreos人工晶体均具有较好的眼稳定性。与Akreos adaptive人工晶状体相比，Big Bag人工晶状体具有较小的眼内高阶像差。昏迷是两组患者的主要区别。

期刊介绍： Eye science was founded in 1985. It is a national medical journal supervised by the Ministry of Education of the People's Republic of China, sponsored by Sun Yat-sen University, and hosted by Sun Yat-sen University Zhongshan Eye Center (in October 2020, it was changed from a quarterly to a monthly, with the publication number: ISSN: 1000-4432; CN: 44-1119/R). It is edited by Ge Jian, former dean of Sun Yat-sen University Zhongshan Eye Center, Liu Yizhi, director and dean of Sun Yat-sen University Zhongshan Eye Center, and Lin Haotian, deputy director of Sun Yat-sen University Zhongshan Eye Center, as executive editor. It mainly reports on new developments and trends in the field of ophthalmology at home and abroad, focusing on basic research in ophthalmology, clinical experience, and theoretical knowledge and technical operations related to epidemiology. It has been included in important databases at home and abroad, such as Chemical Abstract (CA), China Journal Full-text Database (CNKI), China Core Journals (Selection) Database (Wanfang), and Chinese Science and Technology Journal Database (VIP).
