PURPOSE The purpose of this article was to evaluate intraocular pressure (IOP) changes and investigate the relationship with corneal biomechanics after small-incision lenticule extraction (SMILE) and femtosecond laser-assisted laser in situ keratomileusis (FS-LASIK). METHODS A total of 193 eyes of 193 patients who underwent SMILE and FS-LASIK procedures(More)
BACKGROUND To evaluate the refractive outcomes for the correction of low to moderate astigmatism up to 1 year following small incision lenticule extraction (SMILE) surgery. METHODS This retrospective study enrolled 98 eyes from 98 patients who underwent SMILE surgery for the correction of myopia and astigmatism. Only right eyes were included in this study(More)
OBJECTIVE To report the clinical results of micro incision lenticule extraction (MILE) to correct myopia or myopia with astigmatism, and enlighten its viability and mechanism. METHODS Prospective case-control study. All patients enrolled were treated by the VisuMax femtosecond laser system to correct refractive errors. Sixty-one patients underwent MILE(More)
PURPOSE To investigate and compare corneal biomechanical changes in the form of corneal hysteresis (CH) and corneal resistance factor (CRF) after small-incision lenticule extraction (SMILE) and laser-assisted subepithelial keratectomy (LASEK). METHODS In this retrospective observational study, patients who underwent either SMILE (36 eyes, 21 patients) or(More)
During the drying of drops of nanoparticle suspensions, segregation can occur by internal fluid flows toward the contact line, if the contact line is pinned. This leads to a characteristic ring deposit or coffee stain. On solid substrates coffee staining can be eliminated through the use of solvent mixtures that promote Marangoni flows to oppose these(More)
OBJECTIVE To determine whether the long-term visual outcome of small incision lenticule extraction (SMILE) surgery is consistent with the short-term results in high myopic eyes. DESIGN Retrospective cohort study; data collected from 8 August 2011 to 31 August 2015. SETTING Single refractive surgery centre. PARTICIPANTS A total of 156 eyes were(More)
PURPOSE To investigate the aberration compensation between anterior and posterior corneal surfaces after SMILE and FS-LASIK. METHODS Fifty-five subjects (55 eyes) undergoing SMILE and 51 subjects (51 eyes) undergoing FS-LASIK were enrolled in this study. Wavefront aberrations of anterior and posterior corneal surfaces and the whole cornea at 6 mm in(More)
We have successfully used inkjet printing to cryopreserve 3T3 mouse fibroblast cells and human neuroprogenitor cells (NPCs) derived from human embryonic stem cells (hESCs). Sessile drops of volume 114 nl were formed by printing cell suspensions containing dimethyl sulphoxide (DMSO) as a cryoprotection agent (CPA) at rates in the region 100 Hz-20 kHz, from(More)
OBJECTIVE To discuss the accuracy of intraocular pressure (IOP) values measured after small incision lenticule extraction (SMILE), analyze the corneal biomechanical influencing factors of IOP measurement before and after SMILE, and regress the equation of IOP variation for estimating actual IOP. METHODS In this clinical controlled study, 116 eyes (60(More)
PURPOSE To assess the intraoperative complications during small-incision lenticule extraction (SMILE) for myopia and myopic astigmatism correction and evaluate visual outcomes 6 months postoperatively. SETTING Tianjin Eye Hospital, Tianjin, China. DESIGN Retrospective case series. METHODS Patients who had small-incision lenticule extraction surgery(More)
