Importance of calculation of posterior corneal astigmatism on Toric intraocular lens power
Journal Title: Eye Science (Yanke Xuebao) - Year 2021, Vol 36, Issue 2
Abstract
With the cataract surgery evolving from visual restoration surgery to refractive surgery, surgical correction of corneal astigmatism becomes more and more important. For Toric intraocular lens implantation, the surgeon should not only pay attention to the values in surface of anterior corneal astigmatism but also that in posterior corneal astigmatism. Otherwise, unwanted postoperative refractive errors may occur. The mean value of posterior corneal astigmatism was around 0.37 D. In most cases, the posterior corneal astigmatism produces against-the-rule effect. Therefore, the above-mentioned feature of posterior corneal astigmatism should be noticed to prevent the under-correction or over-correction effect of toric lens.
