摘要
目的：屈光不正在沙特阿拉伯很常见，通常通过角膜屈光手术来矫正。然而，并非所有患者都适合接受手术，术后并发症也是一个令人担忧的问题。对于不适合接受角膜屈光手术的患者，可以采用植入式有晶体眼人工晶体（ICL）。ICL 也可用于角膜炎。我们选择评估因屈光不正或角膜炎而植入 ICL 的患者的疗效：我们对年龄在21至45岁之间、在哈立德国王眼科专科医院前节门诊就诊、球面等效度数（SE）在（+16至-23屈光度）之间、在2015年2月至2017年9月期间接受ICL植入术的患者进行了回顾性回顾。手术前后均记录了SE。根据SE，患者被分为两组（近视和远视）。统计分析评估了患者手术前后平均 SE 的变化：我们共发现了 169 只眼睛，其中 155 只（92%）在手术前是近视眼。手术前，平均SE为-8.6，标准差（SD）为4.4。只有 14 只眼睛（8%）在手术前是远视眼，平均 SE 为 +5.5，标准差为 4.8。近视眼手术后与手术前的平均 SE 差异具有统计学意义（平均差异：7.8，标准差：5，P < 0.0001）。远视眼手术后与手术前的 SE 平均值差异也很明显（平均值：-6.1，标准差：5.2，P = 0.0007）。在 32 只患有角膜病的眼睛中，手术前的平均 SE 为-7.9，标准差为 4.1。角膜塑形镜手术后与手术前的平均SE差值为7.2，标准差为4.6，具有统计学意义（P < 0.0001）：结论：ICL 植入术在改善近视眼、远视眼和角膜病眼的 SE 方面效果显著。
Spherical equivalent pre- and post-implantable collamer lens implantation in patients with myopia, hyperopia, and stable keratoconus.
Purpose: Refractive errors are common in Saudi Arabia and keratorefractive surgeries are usually done to correct them. However, not all patients are fit and complications postoperatively are a concern. Implantable collamer lens (ICL) implantation can be used for patients who are not fit for keratorefractive surgeries. ICL can also be used for keratoconus. We elected to evaluate the outcomes of patients who had ICL implantation for refractive errors or keratoconus.
Methods: We retrospectively reviewed patients aged between 21 and 45 years old, who attended the anterior segment clinic at King Khaled Eye Specialist Hospital and who had spherical equivalent (SE) ranging between (+16 to -23 diopters), and had ICL implantation between February 2015 and September 2017. The SE was documented before and after the surgery. Depending on the SE, patients were divided into two groups (myopia and hyperopia). Statistical analysis was done to evaluate the change in mean SE before and after surgery for patients.
Results: We identified 169 eyes and 155 (92%) were myopic before the surgery. Before surgery, the mean SE was -8.6 and the standard deviation (SD) was 4.4. Only 14 eyes (8%) were hyperopic before the surgery with a mean SE of +5.5 and SD of 4.8. The difference in the mean of SE between after and before the surgery for myopic eyes was statistically significant (mean difference: 7.8, SD: 5, P < 0.0001). The difference in the mean of SE between post- and pre-operatively was also significant for hyperopic eyes (mean difference: -6.1, SD: 5.2, P = 0.0007). In 32 eyes with keratoconus, the mean SE before surgery was -7.9 with an SD of 4.1. For the keratoconus eyes, the mean difference of SE between after and before surgery was statistically significant as the mean difference in SE was 7.2 with an SD of 4.6 (P < 0.0001).
Conclusion: The effect of ICL implantation was significant in improving the SE for myopic, hyperopic, and keratoconus eyes.
