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 This study was designed to determine how patients with pellucid marginal corneal degeneration (PMCD) are managed in a tertiary corneal practice. METHODS A retrospective chart review of 45 patients with PMCD from a corneal referral practice was performed. Information collected from the medical records included demographic data, best-corrected(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)
To describe a possible case of unilateral keratoconus in a patient with continual eye rubbing due to an ipsilateral nasolacrimal obstruction in a 17-year-old woman complaint of progressing low visual acuity in the left eye. Presented with constant epiphora in the left eye throughout her life as a result of ipsilateral nasolacrimal obstruction, which(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 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 compare the anti-inflammatory efficacy of ketorolac of tromethamine 0.4% and nepafenac 0.1% eye drops for prophylaxis of cystoid macular oedema (CME) after small-incision cataract extraction. METHODS Patients were assigned randomly to three groups. Group 1 patients received a topical artificial tear substitute (placebo); group 2 received(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.
