“…Additionally, to create a smoother graft-host interface and more accurate incision depth in marginal lamellar keratoplasty, recently-developed techniques (such as excimer laser and femtosecond laser) can be applied to prepare the donor graft and recipient bed. These methods can extensively prevent high astigmatism as well as interlamellar opacification, and provide excellent refractive results (Yilmaz et al, 2007;Mian & Shtein, 2007;Sarayba et al, 2007;Schmitz et al, 2003;Soong et al, 2005). Intraoperative keratometry is a simple device but very useful to guide adjusting sutures to create an even suture tension (Gross et al, 1997).…”
