We report a case of Ferrara intracorneal ring (Mediphacos) implantation and cataract surgery for the correction of pellucid marginal corneal degeneration. Preoperatively, the patient's uncorrected visual acuity (UCVA) was 0.05 in the right eye and 0.10 in the left eye. The best spectacle-corrected visual acuity (BSCVA) was 0.50 with -2.00 -11.25 x 80 in the(More)
PURPOSE To determine whether implantation of an intraocular lens (IOL) with a modified anterior aspheric surface results in reduced spherical aberration and improved contrast sensitivity after cataract surgery. DESIGN Prospective, comparative, interventional case series. METHODS In an intraindividual randomized prospective study of 25 patients with(More)
Purpose. To evaluate visual performance for near, intermediate, and distant vision; complaints of photic phenomena, and patient satisfaction with the new diffractive multifocal IOL used in eyes which underwent phacoemulsification. Methods. Two thousand and five hundred consecutive eyes undergoing Tecnis ZM900 multifocal IOL implantation were included in(More)
PURPOSE To determine whether implantation of an intraocular lens (IOL) with a modified posterior aspherical surface (AcrySof IQ, Alcon Surgical Laboratories) results in reduced ocular aberrations (spherical aberration) and improved contrast sensitivity after cataract surgery. SETTING Brasilia Ophthalmologic Hospital, Brasilia, and Sao Geraldo Eye(More)
PURPOSE To assess the postoperative outcomes of piggyback implantation using the AcrySof ReSTOR intraocular lens (IOL) (model SA60D3, Alcon Surgical Laboratories). SETTING Hospital Oftalmológico de Brasília, Brasília, Brazil. METHODS Thirteen eyes of 7 patients who had phacoemulsification with piggyback IOL implantation were analyzed prospectively. In(More)
PURPOSE To assess the postoperative outcomes of primary piggyback implantation using the Tecnis ZM900 multifocal intraocular lens (IOL) (Advanced Medical Optics). SETTING Hospital Oftalmológico de Brasília, Brasília, Brazil. METHODS Patients who had phacoemulsification with primary piggyback IOL implantation were analyzed prospectively. In all cases, a(More)
PURPOSE To evaluate the efficacy and safety of capturing the intraocular lens (IOL) optic through the anterior capsulorhexis opening in eyes with multifocal IOLs and a residual refractive error. SETTING Hospital Oftalmológico de Brasília, Brasília, Brazil. METHODS Eyes with previous cataract surgery and Tecnis ZM900 multifocal IOL implantation were(More)
PURPOSE The techniques and results of cataract surgery have improved dramatically with technological advancements. One of the reasons for this improvement would be the reduced use of ultrasound with the new phacoemulsification devices. The objective of this study is to confirm the theoretical advantage of the NeoSoniX handpiece. METHODS The authors(More)
PURPOSE To observe the preliminary results based on the efficacy, stability and safety of Artisan anterior chamber intra-ocular lens for the correction of myopia in the first 6 months. METHODS A retrospective study of 18 patients (34 eyes) that received the implantation of Artisan anterior chamber intraocular lens for the correction of myopia was(More)
PURPOSE To evaluate the efficacy, safety, and complications related to the deep anterior lamellar keratoplasty (DALK) using the big-bubble technique. METHODS A prospective study of patients submitted to DALK using the big-bubble technique was conducted. After the procedure, uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), spherical(More)
