Femtosecond laser is a promising new technology for the field of cataract surgery. Early studies have investigated many factors including visual outcomes, complication rates, and financial overhead costs. This review analyzes the most recent clinical studies of visual and refractive outcomes in laser cataract surgery, including those that make comparisons to outcomes found in conventional phacoemulsification cataract surgery.
As femtosecond laser cataract surgery has only emerged recently, there is limited literature available regarding visual outcomes. Most but not all existing studies showed no statistically significant difference in visual acuity and mean absolute refractive error between laser and conventional cataract surgery cases.
The majority of studies examined found visual acuity or refractive outcomes of femtosecond laser to be statistically equivalent to those of conventional phacoemulsification cataract surgery. However, the learning curve involved with laser use may account for these early results, which could potentially improve as better technology and surgical techniques are developed. Further long-term outcomes studies are necessary to more accurately evaluate the benefits and drawbacks of femtosecond laser cataract surgery.
飞秒激光是白内障手术领域一项很有前途的新技术。早期研究已经调查了许多因素，包括视力结果、并发症发生率和财务开销。这篇综述分析了激光白内障手术中视觉和屈光结果的最新临床研究，包括与传统超声乳化白内障手术结果进行比较的研究。
由于飞秒激光白内障手术最近才出现，因此关于视觉结果的文献有限。大多数（但不是全部）现有研究表明，激光和传统白内障手术病例的视力和平均绝对屈光误差没有统计学上的显著差异。
大多数研究发现，飞秒激光的视力或屈光结果在统计学上与传统超声乳化白内障手术相当。然而，激光使用的学习曲线可能导致了这些早期结果，随着更好的技术和手术技术的发展，这些结果可能会有所改善。需要进一步的长期结果研究来更准确地评估飞秒激光白内障手术的利弊。
