PURPOSE To show the clinical use of the NIDEK OPD-Scan wavefront aberrometer and OPD-Station software in anterior segment surgery and pathology. METHODS Case examples are presented along with discussion about the relevant clinical data obtained from the OPD-Scan and OPD-Station software. RESULTS Six case examples including cataract surgery, secondary IOL implantation, phakic intraocular len...

PURPOSE To evaluate the contrast sensitivity and stereopsis tests in patients who underwent bilateral implantation of multifocal intraocular lens. METHODS Tests of contrast sensitivity using the Pelli-Robson chart and stereopsis evaluation with the Titmus Stereo Test were performed in 20 patients 30-60 days after the bilateral implantation of Acrysof Restor multifocal intraocular lens. RESU...

PURPOSE To determine the efficacy, stability, and predictability of refractive surgery for hyperopia using four different procedures: photorefractive keratectomy (PRK), laser in situ keratomileusis (LASIK), implantation of a phakic intraocular lens (PIOL), and removing the transparent lens with IOL implantation. METHODS We operated on 184 eyes with hyperopia; 56 eyes had less than +2.00 D (lo...

BACKGROUND Phakic intraocular lens (PIOL) implantation has been used to correct myopia and myopic astigmatism, although corneal decompensation can occur after implantation. Femtosecond laser-assisted cataract surgery (FLACS) has gained in popularity due to its lower postoperative astigmatism and endothelial loss. Herein, we report the use of FLACS in patients who previously received PIOL implan...

PURPOSE To compare refractive performance of Artisan (Ophtec, Groningen, The Netherlands) or Verisyse phakic intraocular lens and its foldable version, Artiflex (Ophtec), for the correction of moderately high myopia. DESIGN Randomized pilot study. METHODS setting: Institutional practice. patient population: Thirty-one patients with myopia that ranged from -6 to -14 diopters (D). interventio...

BACKGROUND We present two cases of transient vacuolar changes in the anterior subcapsular space of the crystalline lens in patients after posterior chamber phakic intraocular lens implantation. CASE PRESENTATION Implantable collamer lenses (ICL) were implanted in healthy myopic patients. Vacuolar changes developed just after the irrigating procedure through the narrow space between the ICL an...
