PURPOSE To describe a case of severe corneal granular dystrophy with clinicopathologic and molecular genetic findings. METHODS The DNAs of a 53-year-old male patient suffering from corneal granular dystrophy and nonaffected family members were analyzed by molecular genetic methods. Clinical features, and histopathologic and immunohistochemical findings from the penetrating keratoplasty specim...

A 29-year-old male was referred following a flap loss after the creation of a thin, irregular flap with a visual acuity of logMAR 0.1 with -2.0 DS-2.75 DC × 175°. Corneal topography and anterior segment optical coherence tomography revealed an irregular corneal curvature and epithelial profile. Phototherapeutic keratectomy (PTK) followed by Topography - Guided Custom Ablation Treatment (TCAT), ...

PURPOSE To evaluate the outcome of primary or retreatment photorefractive keratectomy (PRK) or phototherapeutic keratectomy (PTK) with mitomycin C (MMC) 0.02% applied prophylactically intraoperatively for the prevention of haze and regression in cases of significant haze and regression after primary PRK, due to previous radial keratotomy (RK), in primary PRK eyes with high myopia, and in comeas...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2016218216 DESCRIPTION Band keratopathy is a chronic degenerative disease characterised by the gradual deposition of greyish opacity in superficial cornea over months or years in eyes with chronic uveitis or on intensive topical therapies containing phosphates. The mechanism of calcium ...

The aim was to assess the results achieved in keratoconic corneas submitted to the combined partial topography-guided photorefractive keratectomy (TG-PRK) and corneal cross linking (CXL) procedure performed on the same day. Four patients underwent this treatment of one eye. Corneal epithelium removal was performed by 50-micron phototherapeutic keratectomy. Then, partial TG-PRK laser treatment w...

PURPOSE To evaluate epithelial healing, postoperative pain, and best spectacle-corrected visual acuity (BSCVA) after transepithelial photorefractive keratectomy (PRK) performed with a new phototherapeutic keratectomy (PTK) mode using the NIDEK CXIII excimer laser. METHODS Fifteen eyes from 10 patients with myopia underwent transepithelial PRK using a multistage program to perform PTK followed...

Purpose. To present a case of a keratoconic patient who underwent epithelial removal with transepithelial phototherapeutic keratectomy (t-PTK) using a 213-nm solid-state laser system followed by corneal collagen cross-linking (CXL) with riboflavin and ultraviolet-A (UVA) irradiation. Methods. Case report. Results. A twenty-four-year-old male with keratoconus underwent CXL treatment after epithe...

This article reviews the current literature pertaining to rainbow glare (RG), including incidence rate, clinical presentation, etiology, prognosis, and management. RG is a rare optical complication of femtosecond laser-assisted in situ keratomileusis that results in patients seeing an array of spectral bands surrounding point sources of light under mesopic and scotopic conditions. The mechanism...

AIM To study the results of combined photorefractive keratectomy (PRK) and phototherapeutic keratectomy (PTK) in myopic patients with recalcitrant recurrent corneal erosion. METHODS PRK was performed in 16 eyes with the Visx 20/20 excimer laser at a central 6.0 mm zone, following total epithelial scraping. Subsequently, confluent 3.0 mm zones of PTK were ablated at a depth of 6.0 microns, sur...
