With the volume of laser in situ keratomileusis procedures growing exponentially, ophthalmologists and other eye-care providers are becoming aware of an uncommon postoperative condition, diffuse lamellar keratitis, that can affect an otherwise ideal outcome. We present our strategy for diagnosing and managing this syndrome, developed from experience in a(More)
PURPOSE To evaluate the refractive results of 193-nm excimer laser photorefractive keratectomy (PRK) performed on 48 highly myopic eyes in a multicenter study. METHODS A Visx 2015 or 2000 argon-fluoride excimer laser and a single-zone ablation technique were used. Postoperatively, eyes were treated with topical fluoromethalone for up to 5 months. Most(More)
A 59-year-old man underwent pterygium excision with intraoperative application of 0.2 mg/ml (0.02%) mitomycin-C placed on the scleral bed for 3 min. A sliding conjunctival flap was used to cover the exposed limbus and sclera. Five weeks after the original surgery, the patient had mild trauma and noted decreased vision. At that time, it was noted that he had(More)
PURPOSE To evaluate the safety and effectiveness of the LipiFlow System compared to the iHeat Warm Compress (WC) for adults with meibomian gland dysfunction (MGD). METHODS This was a non-significant risk, prospective, open-label, randomized, crossover multicenter clinical trial. One hundred thirty-nine subjects were randomized between LipiFlow (n=69) and(More)
OBJECTIVE To evaluate the penetration of commercially available levofloxacin 0.5%, ofloxacin 0.3%, and ciprofloxacin 0.3% topical ophthalmic solutions in human corneal stromal and aqueous humor tissues. METHODS A total of 67 patients scheduled to undergo penetrating keratoplasty for treatment of stromal scar or dystrophy, keratoconus, pellucid marginal(More)
PURPOSE To investigate the outcomes of wavefront-guided photorefractive keratectomy (WG PRK) using prophylactic mitomycin C (MMC) in eyes that had previously undergone radial keratotomy (RK). DESIGN Retrospective, observational, consecutive case series. PARTICIPANTS Thirty-two eyes of 27 patients with previous RK that underwent WG PRK with MMC. (More)
PURPOSE The Cornea Donor Study (CDS) is an ongoing study that is being conducted to determine whether donor age is related to long-term corneal graft survival. Characteristics of the donor population have been evaluated with respect to donor age, endothelial cell density, and death to preservation interval. METHODS Within the context of a prospective,(More)
PURPOSE To report two different cases of sterile, peripheral keratitis following laser in situ keratomileusis (LASIK). METHODS A report of two cases (two eyes of two patients). RESULTS In two patients, peripheral infiltrates appeared 1 day after LASIK. One patient had a history of rheumatoid arthritis and both had peripheral corneal changes that may(More)
The Brown-McLean syndrome is a clinical condition with corneal edema involving the peripheral 2 to 3 mm of the cornea. The edema typically starts inferiorly and progresses circumferentially, but spares the central portion of the cornea. Additionally, the edema is associated with a punctate orange-brown pigmentation on the endothelium underlying the(More)
