PURPOSE To determine whether corneal collagen cross-linking with riboflavin (C3-R) augments the effect of inferior-segment Intacs (Addition Technology) in the treatment of keratoconus. SETTING Private practice, Beverly Hills, California, USA. METHODS A retrospective nonrandomized comparative case series comprised 12 eyes of 9 patients who had(More)
PURPOSE To understand what level of higher order aberrations increases the relative risk of visual symptoms in patients after myopic LASIK. METHODS This study was a retrospective comparative analysis of 103 eyes of 62 patients divided in two groups, matched for age, gender, pupil size, and spherical equivalent refraction. The symptomatic group comprised(More)
BACKGROUND The competing interests of preventing recurrent ischemic optic neuropathy (ION) and minimizing medication side effects make corticosteroid dose reduction in giant cell arteritis (GCA) a difficult problem. The authors sought to determine whether any factors were predictive of recurrent ION. METHODS Retrospective review of the records of 100(More)
A 53-year-old man presented with a longstanding carotid cavernous fistula that could not be embolised completely via the femoral route. A superior ophthalmic vein approach was necessary; however, the vein was thrombosed anteriorly and only intraconal cannulation was possible. The vein was accessed via a superior lid crease approach and the fistula(More)
PURPOSE To analyze postoperative topographic centration when the coaxially sighted corneal light reflex was used for laser centration in hyperopic LASIK. METHODS Centration photographs of 21 eyes (12 patients) that underwent hyperopic LASIK with centration over the coaxially sighted corneal light reflex were reviewed to determine the distance from the(More)
BACKGROUND To validate Randleman's model of ectasia risk factor scores using a large unbiased sample of unpublished cases. METHODS Data were collected retrospectively on 36 eyes with ectasia post laser in situ keratomileusis treated by two surgeons at Vision Eye Institute. The data were then entered into Randleman's risk factor score system. Data were(More)
The recent introduction of femtosecond lasers to cataract surgery has generated much interest among ophthalmologists around the world. Laser cataract surgery integrates high-resolution anterior segment imaging systems with a femtosecond laser, allowing key steps of the procedure, including the primary and side-port corneal incisions, the anterior(More)
Community assembly theories such as species sorting theory provide a framework for understanding the structures and dynamics of local communities. The effect of theoretical mechanisms can vary with the scales of observation and effects of specific environmental factors. Based on 16S rRNA gene tag pyrosequencing, different structures and temporal succession(More)
PURPOSE To report the visual and refractive outcomes in an initial series of eyes undergoing femtosecond laser cataract surgery with implantation of a diffractive multi-focal intraocular lens (IOL). METHODS The first 61 consecutive eyes undergoing femtosecond laser cataract surgery and ReSTOR (Alcon Laboratories Inc) +3.00-diopter (D) add IOL implantation(More)
PURPOSE Underestimation of required intraocular lens (IOL) power with resultant hyperopia is common in post-corneal refractive surgery eyes. A number of methods to minimize error have been proposed but most studies have been small and theoretical. METHODS We retrospectively reviewed 34 eyes that had undergone routine phacoemulsification and IOL(More)
