摘要
背景:人工晶状体巩膜固定术是治疗无晶状体的首选技术,该技术多年来不断发展。这些方法各有优缺点,但主要的问题是人工晶状体的位置、稳定性和并发症。最终的IOL位置是最终视力的主要决定因素,各种成像方式已被用于量化IOL倾斜。目的:应用Scheimpflug显像评价改良法兰巩膜固定人工晶状体(MFSIOL)的人工晶状体倾斜。设计:回顾性分析41例连续行MFIOL的患者。方法:我们对41例连续行MFIOL的患者进行回顾性分析。记录基线和最终最佳矫正视力(BCVA)、屈光不正和临床检查结果。使用Scheimpflug图像计算iol的垂直和水平倾斜。人工晶状体在垂直轴和水平轴上的倾斜度是主要观察指标,BCVA、残余屈光不正、眼压和手术并发症是次要观察指标。结果:平均基线BCVA为logMAR 0.49,分别提高至logMAR 0.356 (p r = 0.089, p = 0.580)、BCVA (r = 0.109, p = 0.498)、最终球面误差(r = 0.081, p = 0.615)、圆柱形误差(r = 0.207, p = 0.195)、轴向长度(r = 0.105, p = 0.514)、IOL度数(r = -0.139, p = 0.388)。结论:改良翼缘人工晶状体(MFIOL)是一种可选择的巩膜内人工晶状体固定技术,具有良好的晶状体稳定性。通过这种技术获得的IOL倾斜是最小的,并且不影响最终的视力结果或眼镜矫正。Scheimpflug成像是测量人工晶状体倾斜的一种简单、无创的方法。改良巩膜法兰固定晶状体位置的scheimpflug显像:本研究旨在分析改良巩膜法兰固定人工晶状体(MFSFIOL)病例中使用scheimpflug显像的晶状体倾斜情况,这是一种减少并发症和简化手术的新技术。人工晶状体(IOL)在可接受的垂直和水平倾斜范围内保持稳定。人工晶状体倾斜对最终最佳矫正视力(BCVA)和眼镜矫正无显著影响。Scheimpflug成像是一种准确且无创的技术,用于评估睫状体内固定患者的晶状体位置。
Scheimpflug imaging for evaluation of intraocular lens position in modified flanged scleral fixated intraocular lens.
Background: Scleral fixation of intraocular lens (IOLs) is the most preferred technique for the management of aphakia and the techniques have evolved over the years. These methods have their advantages and disadvantages, however, the major concern being the position of the intraocular lens, its stability and complications. The final IOL position is the major determinant of the final visual acuity, and various imaging modalities have been used to quantify the IOL tilt.
Objectives: Use of Scheimpflug imaging to evaluate the IOL tilt in modified flanged scleral-fixated intraocular lens (MFSIOL).
Design: Retrospective chart review of 41 consecutive patients who underwent MFIOL.
Methods: We conducted a retrospective chart review of 41 consecutive patients who underwent MFIOL. The baseline and final best-corrected visual acuity (BCVA), refractive error, and clinical examination findings were recorded. The vertical and horizontal tilts of the IOLs were calculated using the Scheimpflug image. The IOL tilt (in degrees) in the vertical and horizontal axes was the primary outcome and the BCVA, residual refractive error, intraocular pressure, and surgical complications were secondary outcome measures.
Results: The mean baseline BCVA was logMAR 0.49, which improved to logMAR 0.356 (p < .005) after the surgery. The mean IOL tilt in the vertical axis was 3.40° (range of 0.0°-8.5°, interquartile range: 1.21-5.66) and in the horizontal axis was 1.35° (range of 0.60°-4.620°, interquartile range: 0.44-1.86), respectively. There was no correlation between angle of IOL tilt and UCVA (r = 0.089, p = 0.580), BCVA (r = 0.109, p = 0.498), final spherical error (r = 0.081, p = 0.615), cylindrical error (r = 0.207, p = 0.195), axial length (r = 0.105, p = 0.514), and IOL power (r = -0.139, p = 0.388).
Conclusion: Modified flanged IOL (MFIOL) is an alternative technique for intrascleral fixation of IOL resulting in good lens stability. The IOL tilt achieved by this technique is minimal and did not influence the final visual outcome or spectacle correction. Scheimpflug imaging is simple and non-invasive method to measure the IOL tilt.
Plain language summary scheimpflug imaging for modified flanged scleral fixated lens position: This study on 41 eyes was aimed to analyze the lens tilt using Scheimpflug imaging in cases of modified flanged scleral fixation of intraocular lens (MFSFIOL), which is a novel technique to minimize the complications and simplify the procedure. The intraocular lens (IOL) remained stable with an acceptable range of vertical and horizontal tilt. There was no significant effect of IOL tilt on the final best-corrected visual acuity (BCVA) or spectacle correction. Scheimpflug imaging is an accurate and non-invasive technique for assessment of lens position in the patients with intrascleral fixation of IOL.
