BACKGROUND The purpose of this study was to evaluate the long-term postoperative incidence of and key factors in the genesis of corneal ectasia after myopic laser-assisted in situ keratomileusis (LASIK) in a large number of cases. METHODS A retrospective review of one surgeon's myopic LASIK database was performed. Patients were stratified into two groups based on date of surgery, ie, group 1 ...

UNLABELLED Corneal ectasia is a progressive, degenerative, and noninflammatory thinning disorder of the cornea. Recently developed corneal reshaping techniques have expanded the treatment armamentarium available to the corneal specialist by offering effective nontransplant options. This review summarizes the current evidence base for corneal collagen crosslinking, topography-guided photorefract...

PURPOSE To evaluate a series of patients with corneal ectasia after LASIK that underwent the Athens Protocol: combined topography-guided photorefractive keratectomy (PRK) to reduce or eliminate induced myopia and astigmatism followed by sequential, same-day ultraviolet A (UVA) corneal collagen cross-linking (CXL). METHODS Thirty-two consecutive corneal ectasia cases underwent transepithelial ...

PURPOSE Four cases of corneal ectasia after small-incision lenticule extraction (SMILE) have been reported. In this review, we provide an overview of the published literature on corneal ectasia after SMILE and risk factors associated with this complication. METHODS Case reports were identified by a search of seven electronic databases for pertinent heading terms between 2011 and July 2017. We...

PURPOSE To evaluate changes in corneal topography indices after corneal collagen crosslinking (CXL) in patients with keratoconus and corneal ectasia and analyze associations of these changes with visual acuity. SETTING Cornea and refractive surgery subspecialty practice. DESIGN Prospective randomized controlled clinical trial. METHODS Corneal collagen crosslinking was performed in eyes wi...

Corneal ectasia is a rare complication involving the visual function. The disease starts sometimes insidiously with a long delay before clinical presentation; it is irreversible with pejorative prognosis (it may be an indication for a corneal graft). These characteristics make it a dreaded complication and give it an adverse and pernicious dimension. It can be caused by thermal burn. We report ...

purpose: to report bilateral terrien’s marginal degeneration, circumferential peripheral corneal ectasia and posterior polymorphous dystrophy in a patient with rheumatoid arthritis. case report: a 24-year-old male patient, who was known case of rheumatoid arthritis from 8 years before, presented with decreased vision since four years ago. comprehensive ophthalmic eye exami-nation revealed bilat...

The development of corneal ectasia has been recognized as a complication after LASIK since the first case report from Seiler and Quurke in the late 1990s. The clinical picture of iatrogenic corneal ectasia resembles that of progressive keratoconus with reduced corneal biomechanical strength, increasing central corneal steepness, irregular refractive errors, and decreasing visual acuity. Since t...

PURPOSE To report an unusual presentation of pellucid marginal degeneration (PMD). CASE REPORT A 57-year-old man with history of corneal ectasia experienced acute hydrops and spontaneous corneal perforation in his right eye. Examination revealed PMD in both eyes. After initial treatment with cyanoacrylate adhesive and a bandage contact lens, therapeutic penetrating keratoplasty was undertaken...
