PURPOSE To compare the outcome of phacoemulsification surgery in patients with and without prior vitrectomy, adjusted for confounding factors. DESIGN Retrospective cohort study. PARTICIPANTS AND CONTROLS Thirty-one consecutive eyes undergoing phacoemulsification after pars plana vitrectomy (PPV) and 116 consecutive eyes undergoing phacoemulsification(More)
PURPOSE To investigate possible adverse effects of a yellow-tinted intraocular lens (IOL) on scotopic sensitivity and hue discrimination. SETTING Departments of Ophthalmology, Columbia University and New York University School of Medicine, New York, New York, USA. METHODS Nine patients with a yellow-tinted IOL in 1 eye and a colorless ultraviolet IOL in(More)
PURPOSE To compare the incidence of visually significant pseudophakic macular edema after uneventful phacoemulsification in patients treated postoperatively with topical prednisolone and those treated with topical prednisolone and nepafenac 0.1% suspension (Nevanac). SETTING Edward S. Harkness Eye Institute of Columbia University, New York, New York, USA.(More)
PURPOSE Corneal collagen cross-linking through UVA-riboflavin photochemistry (UVAR) has been shown to be an effective treatment for keratoconus and related keratectasias. In recent studies using sclera, the authors observed that short-chain aliphatic beta-nitro alcohols can cross-link collagenous tissue under physiologic conditions. Thus, this study was(More)
The success of riboflavin photochemical cross-linking of the cornea in treating keratoconus and post-surgical keratectasia has prompted interest in cross-linking scleral tissue with a potential application to stabilize myopic progression. Applying an UVA light source to the sclera is difficult, particularly in the posterior region. An alternate(More)
Mutations in the BIGH3 gene on chromosome 5q31 cause four distinct autosomal dominant diseases of the human cornea: granular (Groenouw type I), Reis-Bücklers, lattice type I, and Avellino corneal dystrophies. All four diseases are characterized by both progressive accumulation of corneal deposits and eventual loss of vision. We have identified a specific(More)
Continuous refinements in vitreoretinal surgical techniques and an increasing number of posterior segment disorders are being successfully managed with pars plana vitrectomy (PPV). This has resulted in an increase in the number of vitrectomized eyes seen by cataract surgeons. Cataract surgery in previously vitrectomized eyes has been reported to be more(More)
PURPOSE To obtain objective measurements of corneal light scattering after excimer laser keratectomy, and to evaluate the relation of light scattering to clinical haze grading and visual acuity. METHODS The authors measured best-corrected visual acuity, subjective clinical haze grade, and corneal light-scattering index in patients undergoing(More)
We report an effective alternative treatment of profound chronic exposure keratopathy in a proptotic eye due to intraorbital extension of basal cell carcinoma. The corneal surface gradually reepithelialized in a 6-week period after the first application of Tegaderm transparent dressing (3M, St. Paul, MN, U.S.A.) with instillation of antibiotic ointment on(More)
