Unexpectedly high corneal flap thickness and ectasia after mechanical LASIK

Revista Brasileira de Oftalmologia, 2023
LASIK is a refractive surgical procedure in which a corneal flap is created to expose the corneal stromal bed. Preoperative estimation of corneal flap thickness is necessary to calculate the percentage tissue altered in LASIK, an important quantitative ...

Management of advanced corneal ectasias [PDF]

British Journal of Ophthalmology, 2015
Corneal ectasias include a group of disorders characterised by progressive thinning, bulging and distortion of the cornea. Keratoconus is the most common disease in this group. Other manifestations include pellucid marginal degeneration, Terrien's marginal degeneration, keratoglobus and ectasias following surgery. Advanced ectasias usually present with
