Jul 20, 2023 · Keratectasia is an eye condition with bulging and cornea thinning, leading to decreased visual acuity. The disease can be caused due to LASIK surgery, an eye disorder, or any trauma to the eye. The eye doctor may diagnose the condition by comprehensive eye examinations and various diagnostic tests.

Dec 14, 2024 · Keratectasia, encompassing both naturally occurring and surgically induced corneal thinning and protrusions, presents a critical concern in the domain of ophthalmology, particularly within the realm of refractive surgery.

Ectasia after refractive surgery is a progressive increase in myopia, with or without increasing astigmatism, with keratometric steepening of the cornea and topographic asymmetric inferior corneal steepening. Over time there can be associated thinning …

Background: Patients with unilateral post-LASIK keratectasia (KE) have clinical ectasia in one eye but not in the fellow eye. As serious complications, these cases are rarely reported but are worth investigating. This study aimed to explore the ...

Apr 15, 2015 · Corneal ectasia can severely impair vision, especially in the progressive form caused by the inherent structural instability of the cornea. The clinical signs can challenge your detection skills—corneas with subclinical keratoconus are clinically normal in appearance but have subtle irregularities on corneal topography.

Feb 27, 2025 · Keratectasia can have several causes, including genetic factors, eye trauma, and conditions that affect the structure of the cornea. It can also be related to previous eye surgery, such as refractive surgery (LASIK), which can weaken the …

Bulging of the CORNEA due to weakening from thinning or softening (KERATOMALACIA). In keratectasia there is a danger of rupture under the influence of the normal intraocular pressure and urgent measures are needed to avoid this. Sometimes a ‘bandage’ contact lens is used; more often a corneal graft is performed.

The aim of this study was to evaluate the distribution of new Corneal Visualisation Scheimpflug Technology (Corvis ST) parameters in normal, Post-laser in situ keratomileusis (LASIK), Post-LASIK keratectasia (KE) and keratoconus (KC) eyes, and ...

May 5, 2016 · To give us the best chance of detecting corneas that are susceptible to keratectasia, we need to do three things: clarify our terminology, develop appropriate statistical methods, and use an applicable clinical model. Figure 3. Normal cornea, with a SCORE of -2.2.

Jul 1, 2024 · This review traces the development of the BEST as an addition to the tomographic ABCD staging system and highlights its strengths and limitations when applied in daily practice for the detection, monitoring and progression assessment in keratectasia.
