PURPOSE To evaluate the efficacy of photorefractive keratectomy (PRK) using the advanced personalized treatment (APT) nomogram for correction of moderate to high astigmatism. METHODS This prospective interventional case series included 60 consecutive eyes of 30 patients undergoing wavefront-guided PRK (Zyoptix 217 Z100 excimer laser, Bausch & Lomb, Munich, Germany) using the APT nomogram and ...

Abstract Background Myopic shift and biometric ocular changes have been previously observed after scleral buckling (SB) surgery in rhegmatogenous retinal detachment (RRD), but long term-term outcomes had not yet explored. The purpose of present study is to evaluate term patients with primary macula-on RRD treated SB. Methods In this retrospective, observational study, we reviewed the medical re...

PURPOSE To evaluate the visual performance by high contrast visual acuity, contrast sensitivity and wavefront in myopic patients with or without astigmatism corrected with spectacles and with three different soft contact lenses [Acuvue 2 (Vistacon J&J Vision Care Inc., USA), Biomedics 55 (Ocular Science, USA), and Focus 1-2 week (Ciba Vision Corporation, USA)]. METHODS An interventional prosp...

PURPOSE To examine Chinese neonatal infants with both cycloplegic and noncycloplegic retinoscopy and to compare the distribution of refractive errors for the two techniques. METHODS Cycloplegic retinoscopy was performed by two experienced pediatric ophthalmologists on 81 neonatal infants randomly selected from a group of 185 neonates who had undergone noncycloplegic retinoscopy. All infants w...

Animal studies show that the rate of recovery from experimentally induced refractive errors is related to the level of ametropia induced. The present study examined the rate of emmetropisation occurring in a sample of 22 human infants refracted by near retinoscopy during the first six months of life and then again between 12 and 17 months old. None of the subjects were myopic. Regression analys...

Abstract Background To evaluate early optical quality outcomes after small-incision lenticule extraction (SMILE) surgery for correcting high myopic astigmatism. Methods This retrospective study enrolled 55 eyes from 37 patients who had preoperative astigmatism of ≥2.00 diopters (D) been treated with SMILE surgery. Preoperatively, the mean cylinder was − 2.41 ± 0.54 D (range, 2.00 to 4.50 D). Th...
