INTRODUCTION To evaluate the vitreoretinal complications in myopes after Visian implantable collamer lenses (ICL) implantation. MATERIALS AND METHODS This is a retrospective, observational, non-comparative clinical study that evaluated 617 consecutive myopes who underwent ICL implantation at the Department of Refractive Surgery, Yemen Magrabi Hospital, Sana'a, Yemen between July 2006 and May ...

PURPOSE To compare the intraocular pressure (IOP) values during a 3-month period after implantation of the new Visian Implantable Collamer Lens (ICL; STAAR Surgical Company, Nidau, Switzerland) V4c design with CentraFLOW technology without iridotomy using a standard procedure followed by implantation of the conventional ICL V4b model. DESIGN Retrospective cohort study. METHODS This study in...

PURPOSE To evaluate visual and refractive outcomes and safety of implantable collamer lens (ICL) implantation in low-to-moderate myopia. SETTING Private Practice - Dougherty Laser Vision, Westlake Village, CA, USA. METHODS A chart review was performed in 56 (104 eyes) consecutive patients who underwent implantation of the Visian ICL V4 model. Inclusion criteria were age between 21 and 40 ye...

OBJECTIVES To assess the stability of axis and patient satisfaction after toric visian implantable collamer lens (TICL) implantation for moderate to high myopic astigmatism. METHODS Total 33 eyes of 21 consecutive patients who underwent implantation of TICL for the correction of moderate to high myopic astigmatism were recorded and a minimum follow-up of six months was performed. The deviatio...

Purpose: To assess the visual and refractive outcomes after implantation of Toric Implantable Collamer Lens (T-ICL) in compound myopic astigmatism Methods: In this prospective study, 28 eyes with manifest refraction spherical equivalent (MRSE) errors of -10.94±4.09 diopter (D) and mean cylindrical errors of -3.47±1.39 D underwent T-ICL implantation. Six months after surgery, best corrected and ...

PURPOSE To evaluate the long-term safety and efficacy of posterior chamber collagen copolymer phakic intraocular lens (pIOL) implantation to correct myopia. SETTING Fernández-Vega Ophthalmological Institute, Oviedo, Spain. DESIGN Cohort study. METHODS Uncorrected (UDVA) and corrected (CDVA) distance visual acuities, refraction, pIOL vault, endothelial cell loss, and adverse events were ev...

PURPOSE To evaluate the efficacy, safety, and predictability of sequential implantation of Keraring intrastromal corneal ring segments (ICRS) and an Implantable Collamer Lens phakic intraocular lens (pIOL) with corneal relaxing incisions for refractive correction of keratoconus. SETTING Fernández-Vega Ophthalmological Institute, Oviedo, Spain. DESIGN Cohort study. METHODS This study compr...

Purpose: The purpose of the current study was to investigate the pathogenesis of visual fatigue in patients after implantable collamer lens (ICL) implantation based on an evaluation of accommodation function. Methods: Thirty patients (12 males and 18 females) with high myopia underwent a toric or non-toric ICL procedure. Accommodation function was tested pre-operatively and 1, 3, and 6 months p...

PURPOSE To assess axis alignment and stability of the Toric Implantable Collamer Lens (TICL; STAAR Surgical Co) over time. METHODS Thirty-five consecutive eyes of 19 patients received the TICL for treatment of myopic astigmatism. Manifest refraction spherical equivalent (MRSE) and manifest refractive cylinder were measured preoperatively and at 3 months postoperatively. The axis alignment of ...
