简要总结
To assess the effectiveness of the Verion-LenSx guided arcuate incision technique to reduce astigmatism in a pseudophakic population.
详细描述
The purpose of this study is to evaluate the effectiveness of corneal arcuate incisions when they are performed with a femtosecond laser system on subjects who have had previous cataract surgery. The procedure to be used would not be different from that employed during cataract surgery, except that the only corneal incisions made would be the partial-depth arcuate incisions at the laser.

研究组 & 干预措施
Verion-LenSx
The Verion-LenSx femtosecond laser system will be used to perform one or two corneal arcuate incisions.
干预措施: Verion-LenSx (Procedure)
结局指标
主要结局
Uncorrected Monocular Distance Visual Acuity
时间窗: 60 days (+/- 10 days) after laser treatment
Uncorrected monocular distance visual acuity, measured on a logMAR scale, (logarithm of the Minimum Angle of Resolution) which is a measure of visual acuity in which the smaller values indicate better visual acuity.
次要结局
- Change in Corneal Astigmatism(60 days (+/- 10 days) after laser treatment)
- Change in Refractive Cylinder(60 days (+/- 10 days) after laser treatment)
- Spectacle Independence at Distance(60 days (+/- 10 days) after laser treatment)
