OBJECTIVE To prospectively study the effects of the use of Intacs microthin prescription inserts (Addition Technology Inc, Fremont, Calif) for the postoperative management of corneal ectasia resulting from laser in situ keratomileusis (LASIK). METHODS In this prospective nonrandomized clinical trial, 10 eyes of 7 patients with post-LASIK corneal ectasia (2 men and 5 women) aged 33 to 46 years...

Corneal cross-linking (CXL) is increasingly performed in ophthalmology with high success rates for progressive keratoconus and other types of ectasia. Despite being an established procedure, some molecular and clinical aspects still require additional studies. This review presents a critical analysis of some established topics and others that are still controversial. In addition, this review ex...

Keratoconus is a bilateral non-inflammatory corneal ectasia with an incidence of approximately one per 2000 in the general population. Contact lenses are the most common treatment. When contact lenses fail, a surgical approach is necessary for visual rehabilitation. Penetrating keratoplasty has been the traditional and most common mode of treatment and has excellent results. 3 However, more rec...

Several methods have been described in the literature to both evaluate and document progression in keratoconus, but there is no consistent or clear definition of ectasia progression. The authors describe how modern corneal tomography, including both anterior and posterior elevation and pachymetric data can be used to screen for ectatic progression, and how software programs such as the Enhanced...

BACKGROUND Posterior keratoconus is a rare cause of a corneal opacity in an infant. It is characterized by thinning of the posterior cornea without ectasia of the anterior cornea. Imaging of this condition with anterior segment optical coherence tomography (AS-OCT) has not been reported in the literature. CASE PRESENTATION A six week old African-American male presented with a congenital corne...

PURPOSE Collagen cross-linking (CXL) for post-laser-assisted in situ keratomileusis (LASIK) ectasia (PLE) is traditionally performed either epi-on or epi-off on the corneal surface. This study describes a novel technique in treating early PLE with under-flap CXL (ufCXL) to the stromal bed and reports on 6-month outcomes. PATIENTS AND METHODS Case series of seven patients (eight eyes) with top...

The management of keratoconus and post – LASIK ectasia included until recently spectacle correction, Hard Fitted Gas Permeable Contact Lenses, Intrastromal Corneal Ring Segments. All these interventions are purely symptomatic and their only aim is the improvement of visual function of patients, without interfering with the pathophysiology of the ectatic disorders. The only actual treatment for ...
