Purpose To evaluate the effect of cap-lenticule diameter difference (CLDD) on the visual outcome and higher-order aberrations (HOAs) of small-incision lenticule extraction (SMILE). Methods A total of 132 patients who had bilateral SMILE for myopia or myopic astigmatism were included. The CLDD was 0.4 mm in 54 patients (group 1) and 1.0 mm in 78 patients (group 2). The refractive parameters, u...

Refractive surgical treatment of hyperopia still remains a challenge for refractive surgeons. A new nomogram of small incision lenticule extraction (SMILE) procedure has recently been developed for the treatment of hyperopia. In the present study, we aimed to evaluate the wound healing and inflammatory responses of this new nomogram (hyperopic-SMILE), and compared them to those of hyperopic-las...

The three-dimensional finite element model of the postoperative whole human eye after small incision lenticule extraction (SMILE) surgery and axisymmetric air-puff were established, influencing factors in Air-puff test explored from displacement nephogram on anterior corneal surface. Our results showed that maximum depression was positively correlated with corrected diopter when peak pressure e...

purpose: to evaluate the anatomical and visual outcomes of descemet`s stripping with endothelial keratoplasty (dsek) in patients with bullous keratopathy after cataract surgery. methods: the study was performed on 20 eyes of 20 patients (13 male, 7 female) with bullous keratopathy (pseudophakic=15, aphakic=5). donor lenticule was prepared using a microkeratome (n=12) or manual dissection (n=8)....

PURPOSE To quantify the effect of small incision lenticule extraction (SMILE) on the corneal biomechanics using Scheimpflug noncontact tonometer (Corvis ST). METHODS Twenty eyes of twenty patients, evaluated as eligible for surgery, with high myopia and/or moderate myopic astigmatism, underwent small incision lenticule extraction (SMILE). All patients underwent Corvis ST preoperatively and po...
