上海植入晶体和激光准分子手术的区别

      Implantable contact lenses (ICLs) appear to correct high myopia more accurately than customized all-laser LASIK (IntraLASIK), and the phakic lenses also provide a better quality of vision, according to G. Peyton Neatrour, MD. He is an assistant professor of ophthalmology at Eastern Virginia Medical School, Norfolk, VA, and is in private practice with Beach Eye Care, Virginia Beach, VA.

     G. Peyton Neatrour医生说，人工晶体植入术矫正高度近视的准确性远高于所有激光准分子手术，眼内晶体植入术同样也能为患者提供一个佳的视觉质量。G. Peyton Neatrour医生是东弗吉尼亚医科大学眼科助教，并在一家Beach Eye Care私人诊所行医。

     Dr. Neatrour and colleagues conducted a retrospective study of 79 consecutive eyes undergoing vision correction for high myopia. Patients chose either to undergo phakic IOL implantation or IntraLASIK (CustomVue IR, Advanced Medical Optics [AMO]) after receiving recommendations from their ophthalmologists.

     Neatrour医生和他的同事对于79只进行过高度近视矫正手术的眼睛进行了一项回顾性研究。患者都是由他们的眼科医生推荐进行眼内晶体植入术或准分子手术。

     Researchers measured uncorrected visual acuity (UCVA), gain or loss of best spectacle-corrected visual acuity (BSCVA), accuracy, high-order aberrations (HOAs), contrast sensitivity, complication rate, and enhancement frequency. They found that the phakic IOLs provided results superior to LASIK in regard to UCVA, gain in BSCVA, accuracy within 0.05 D, fewer HOAs, and contrast sensitivity.

     研究中，他们对患者的裸眼视力、佳矫正视力的变化、准确度、高阶像差、对比敏感度、并发症概率及增强手术的比例分别进行了测试，发现眼内晶体植入术在裸眼视力、佳矫正视力的提高、准确度（达到0.05D），高阶像差、对比敏感度等方面的结果均优于准分子手术。

      The investigators also measured patient satisfaction by having each patient rate effects on a scale of one (very satisfied) to five (very unsatisfied).

      研究者们同样也对患者满意度进行了调查，从非常满意（1）到非常不满意（5），以5分制表示。

      "We asked about sharpness, comfort, consistency, day and night vision, and glare, and we found the ICLs had a very slightly lower score (1.5) versus 1.6 with custom endpoints," Dr. Neatrour said. "When we looked at condition occurrences of dryness, blurriness, fluctuation in vision, glare, halos, difficulty at night, or ghosting, we found the custom IntraLASIK group did slightly better than the ICL group.

      “我们对视觉敏锐度、舒适度、稳定性、日间及夜间视力、眩光方面进行了提问，发现ICL手术患者的评分略低（1.5），相比于个性化激光手术的评分（1.6），”Neatrour医生说，“我们看到在术后干眼症、模糊情况、视觉波动、光晕、眩光、夜视力困难等问题的发生上，准分子并不比ICL来得好。”

      "Then we asked that question about, 'How was your vision with glasses or contacts before versus how your vision is afterward without any vision correction?' and all the way down the line on those symptoms, ICLs surpassed the custom IntraLASIK," Dr. Neatrour said.

     “然后我们问了一些问题，如：手术之前你配戴框架或隐形眼镜的视力同手术后的裸眼视力相比如何？所有的这些症状ICL的益处均超过个性化准分子LASIK手术，”Neatrour医生说。

     The groups had similar equivalent enhancement rates, according to wavefront analysis (WaveScanWaveFront, AMO). The amount of preoperative astigmatism with lens implantation was a predisposing factor to requiring an enhancement. The need for astigmatism-correcting enhancements should be minimized with the future availability of toric ICLs, Dr. Neatrour concluded.

     据分析，两组需要进行增强手术的比例类似。。术前的散光量直接影响ＩＣＬ植入患者是否需要增强手术。。当Toric ICL投入使用后，ＩＣＬ手术的增强手术率会有大幅下降，Neatrour医生总结道。
