To describe femtosecond laser cataract surgery and discuss the published peer-reviewed articles to have a fair evaluation of this new technology and its comparisons to conventional phacoemulsification surgery.
The technology information released in this article comes from the key individuals in each of the U.S. Food and Drug Administration-approved companies and from the available commercial information. Bibliographic research was performed in PubMed and MEDLINE for the published prospective or retrospective clinical studies.
The femtosecond laser has been reported to be safe intraoperatively and postoperatively, with less cornea and macula effect than conventional phacoemulsification. The incision is integrated, stable, and aberration free. Many studies reported the high precision of the capsulotomy over manual continuous curvilinear capsulorhexis, which favors less intraocular lens tilt, higher optical quality, and more accurate premium intraocular lens centration. The lens fragmentation is effective with significant reduction of the phacoemulsification power and effective phacoemulsification time. The refractive difference between femtosecond laser and standard phacoemulsification is minimal, with no difference in corrected distance visual acuity, but the optical quality and the internal aberrations results are significantly better for femtosecond laser phacoemulsification.
Femtosecond laser cataract surgery is a good addition to cataract surgery despite its few remarkable advantages among experienced phacoemulsification surgeons.
描述飞秒激光白内障手术，并讨论已发表的同行评议文章，以对这项新技术进行公正评估，并将其与传统的超声乳化白内障吸除术进行比较。
本文中发布的技术信息来自美国食品和药物管理局批准的每家公司的关键人员，以及可用的商业信息。在 PubMed 和 MEDLINE 中进行了已发表的前瞻性或回顾性临床研究的文献检索。
飞秒激光已被报道在术中及术后均安全，其对角膜和黄斑的影响小于传统的超声乳化白内障吸除术。切口整合、稳定且无像差。许多研究报告称，与手动连续环形撕囊相比，囊袋切开术具有更高的精确性，这有利于减少人工晶状体倾斜、提高光学质量和更精确的人工晶状体中心定位。与传统超声乳化白内障吸除术相比，飞秒激光白内障乳化术能有效减少超声乳化能量和时间。飞秒激光白内障手术与标准超声乳化白内障手术的屈光差异极小，术后矫正视力无差异，但飞秒激光白内障乳化术的光学质量和内部像差结果明显更好。
尽管在经验丰富的超声乳化白内障吸除术医生中，飞秒激光白内障手术的优势并不明显，但它仍是白内障手术的良好补充。
