To assess rotational stability, axial stability, decentration, and tilt of the Rayner RAO800C single-piece hydrophobic acrylic intraocular lens (IOL) (Rayner Intraocular Lenses Ltd) from end of surgery to 4 to 7 months postoperatively.
Surgeries were performed at the Department of Ophthalmology at the Medical University of Vienna. A total of 130 eyes of 68 patients received an aspheric hydrophobic Rayner RAO0800C IOL. IOLs were randomly implanted to the 0 ± 10, 45 ± 10, 90 ± 10, or 135 ± 10 degree axis. Baseline measurement was performed with the patient still supine on the operating table. Axis alignment after 1 hour, 1 week, 1 month, and 4 months was evaluated by retroillumination pictures. Postoperative IOL decentration, tilt, and aqueous depth at 4 months were assessed using an anterior segment swept-source optical coherence tomography.
Absolute median IOL rotation from end of surgery to 4 months was 2.4 degrees (range: 0.0 to 85.0 degrees). Median IOL rotation from end of surgery to 1 hour, 1 hour to 1 week, 1 week to 1 month, and 1 month to 4 months was 1.6 (range: 0.0 to 86.2), 1.1 (range: 0.0 to 28.8), 0.6 (range: 0.0 to 5.2), and 0.7 (range: 0.0 to 2.6) degrees. Respective proportions of IOLs rotating more than 5, 10, and 20 degrees from end of surgery to 4 months were 23.9%, 11.0%, and 6.4%. Horizontal and vertical decentration at 4 months was -0.09 ± 0.14 and 0.09 ± 0.14 mm, respectively. Horizontal and vertical tilt at 4 months was -4.78 ± 1.36 and -1.58 ± 1.10 degrees, respectively. A posterior axial shift of 0.052 ± 0.055 mm was observed from 1 week to 4 months.
Although median IOL rotation appeared to be low, a significant proportion of IOLs rotated postoperatively. Decentration and tilt values were generally low. A minimal posterior optic shift was observed after 1 week. [J Refract Surg. 2021;37(2):112-118.].
评估 Rayner RAO800C 单件疏水性丙烯酸一体式人工晶状体（IOL）（Rayner 人工晶状体有限公司）在术后结束到术后 4 至 7 个月的旋转稳定性、轴向稳定性、偏心度和倾斜度。
在维也纳医科大学眼科进行手术。68 例患者的 130 只眼接受了非球面疏水性 Rayner RAO0800C IOL。IOL 随机植入 0±10、45±10、90±10 或 135±10 度轴。基线测量是在患者仍仰卧在手术台上时进行的。术后 1 小时、1 周、1 个月和 4 个月时通过后照光照片评估轴对齐情况。术后 4 个月时使用前节扫频源光学相干断层扫描评估 IOL 偏心度、倾斜度和房水深度。
从手术结束到 4 个月时，IOL 旋转的中位数为 2.4 度（范围：0.0 至 85.0 度）。从手术结束到 1 小时、1 小时到 1 周、1 周到 1 个月和 1 个月到 4 个月的中位数 IOL 旋转分别为 1.6（范围：0.0 至 86.2）、1.1（范围：0.0 至 28.8）、0.6（范围：0.0 至 5.2）和 0.7（范围：0.0 至 2.6）度。从手术结束到 4 个月时 IOL 旋转超过 5、10 和 20 度的比例分别为 23.9%、11.0%和 6.4%。4 个月时水平和垂直偏心度分别为-0.09±0.14 和 0.09±0.14mm。4 个月时水平和垂直倾斜度分别为-4.78±1.36 和-1.58±1.10 度。从 1 周到 4 个月观察到后轴有 0.052±0.055mm 的偏移。
尽管 IOL 旋转的中位数似乎较低，但术后相当比例的 IOL 发生了旋转。偏心度和倾斜度通常较低。术后 1 周后观察到最小的后光学移位。
