purpose: to evaluate the results of laser in situ keratomileusis (lasik) retreatment in  patients with postoperative regression. methods: in a retrospective interventional case series, 153 eyes of 113 patients who had undergone lasik retreatment for postoperative regression were evaluated. both initial lasik and retreatment were performed with a nidek: ec 5000 excimer laser, and flap was made w...

PURPOSE To investigate non-cycloplegic changes in refractive error prior to the onset of presbyopia. METHODS The Aston Longitudinal Assessment of Presbyopia (ALAP) study is a prospective 2.5 year longitudinal study, measuring objective refractive error using a binocular open-field WAM-5500 autorefractor at 6-month intervals in participants aged between 33 and 45 years. RESULTS From the 58 p...

Aim: We aimed to compare the results of photorefractive keratectomy (PRK) and femtosecond-assisted laser in situ keratomileusis (FS-LASIK) procedures treatment myopia myopic astigmatism.
 Material Method: Seventy eyes 35 patients with and/or astigmatism who had undergone PRK procedure were compared retrospectively 70 FS-LASIK procedure. 
 Results: All completed 2-year follow-up period...

BACKGROUND The aim of this study was to evaluate long-term efficacy, safety, stability, and predictability of photorefractive keratectomy (PRK) as treatment of astigmatism. MATERIAL/METHODS Ninety-four eyes of 52 patients, treated with PRK for compound myopic astigmatism, compound hyperopic astigmatism, and mixed astigmatism were studied during a 36-month period. Main outcome measures were un...

To evaluate the refractive outcomes of balanced salt solution infiltration during small-incision lenticule extraction (SMILE).This randomized prospective study enrolled 52 patients (104 eyes) with myopic astigmatism. Patients underwent SMILE to correct the myopic astigmatism in Daping Hospital of the Third Military Medical University between January and July 2013. One eye of each patient receiv...

PURPOSE To examine the symmetry of corneal changes following near work in the fellow eyes of non-amblyopic myopic anisometropes. METHODS Thirty-four non-amblyopic, myopic anisometropes (minimum 1 D spherical equivalent anisometropia) had corneal topography measured before and after a controlled near work task. Subjects were positioned in a headrest to minimise head movements and read continuo...

PURPOSE To compare toric implantable collamer lens (T-ICL), femto-LASIK, and ReLEx SMILE for the treatment of low to moderate myopic astigmatism in terms of long-term visual and refractive outcomes and predictability of astigmatic correction. MATERIALS AND METHODS The study included 30 eyes from 30 patients between the age groups of 21 and 40 years, undergoing bilateral surgery with any of th...
