摘要

目的:从双眼视力的角度研究植入式角膜塑形镜(ICL)手术后视力回退的相关因素,并建立屈光度长期变化的预测模型:这是一项前瞻性研究,研究对象为在广东省总医院接受ICL手术的30名受试者(60例植入者)。对手术前、手术后1个月和1年的矫正远视力、未矫正远视力、球面等效视力(SE)、轴向长度和使用虚拟现实进行的双眼检查进行了分析:术前平均 SE 为 (-12.01 ± 0.86) D,术后 1 个月平均 SE 为 (-0.44 ± 0.13) D,术后 1 年平均 SE 为 (-0.97 ± 0.15) D。术后 1 年的平均回归(-0.53 ± 0.25 D of SE)显著(P = 0.01)。基线和术后一年的平均轴长分别为(28.35 ± 0.39)毫米和(28.91 ± 0.57)毫米。回归与双眼平衡差(r = 0.553,P = 0.002)和知觉眼位偏移程度相关,尤其是水平偏移(r = -0.620,P = 0.000)。与近视回归相关的重要变量是术前水平知觉眼位偏移(B = -0.007,P = 0.001)和双眼平衡差(B = 0.146,P = 0.012):结论:感知觉眼位偏移和双眼平衡差会导致双眼注视不稳定,不稳定的视网膜图像会产生 "微视网膜聚焦现象",导致轴长拉长,从而导致ICL手术后近视度数下降。

Virtual Reality Assessment Reveals Myopic Regression After ICL Implantation in High Myopia.

Purpose: To investigate the correlative factors of vision regression after Implantable Collamer Lens (ICL) surgery from the perspective of binocular vision and to develop a predictive model for the refractive change over the long term.

Methods: This was a prospective study of 30 subjects (60 implants), who underwent ICL surgery at Guangdong General Hospital. Corrected distance visual acuity, uncorrected distance visual acuity, spherical equivalent (SE), axial length and binocular examination using virtual reality were analyzed before, 1 month and 1 year after the surgery.

Results: Mean SE was (-12.01 ± 0.86) D preoperatively, (-0.44 ± 0.13)D 1 month postoperatively and (-0.97 ± 0.15)D 1 year postoperatively. The average regression 1 year postoperatively (-0.53 ± 0.25D of SE) was significant (P = 0.01). Mean axial length at the base line and 1 year after the surgery was (28.35 ± 0.39) mm and (28.91 ± 0.57) mm. The regression was correlated with the binocular equilibrium difference (r = 0.553, P = 0.002), and the degree of perceptual eye position shift, especially the horizontal shift (r = -0.620, P = 0.000). The important variables relevant to myopic regression were preoperative horizontal perceptual eye position shift (B = -0.007, P = 0.001) and binocular equilibrium difference (B = 0.146, P = 0.012).

Conclusion: Perceptual eye position deviation and the binocular equilibrium difference could cause binocular gazing instability, and the unstable retinal image created a 'micro retinal-defocus phenomena', leading to an elongation of the axial length and resulting in myopic regression after ICL surgery.

期刊介绍: This book series was started in 1990 to promote research conducted under the auspices of the EC programmes’ Advanced Informatics in Medicine (AIM) and Biomedical and Health Research (BHR) bioengineering branch. A driving aspect of international health informatics is that telecommunication technology, rehabilitative technology, intelligent home technology and many other components are moving together and form one integrated world of information and communication media.
