What is Keratectasia?

Keratectasia is a rare but serious complication of refractive surgery that leads to a significant and progressive decrease of CDVA and corneal thickness. Preoperative FFKC has been considered the major reason for corneal ectasia following LASIK or PRK.

How do you treat corneal ectasia?

Management options for postoperative ectasia include conservative management with various types of contact lenses such as rigid gas permeable lenses, custom wavefront-guided soft contact lenses, hybrid lenses and tandem soft contact lens-rigid gas permeable lenses.

How do you treat post ectasia after Lasik?

Treating Post-Surgical Ectasia The most effective way to treat post-surgical ectasia is with gas permeable (GP) scleral lenses. Unlike standard contact lenses, GP lenses are rigid. They maintain their shape on the eye, where soft lenses conform to the surface of the cornea.

Is post Lasik ectasia progressive?

It is characterized by progressive thinning with central and inferior steepening of the cornea. The incidence of progressive corneal ectasia after LASIK has been estimated to be 0.2% (Rad et al., 2004).

Is corneal ectasia the same as keratoconus?

What are ectasia and keratoconus? “Corneal ectasia” refers to a group of non-inflammatory disorders of the eye that involve the bilateral thinning of the cornea. Keratoconus is a specific type of corneal ectasia in which the cornea thins and weakens, leading to bulging and distortion.

What is Keratoglobus?

Keratoglobus is a rare noninflammatory corneal thinning disorder characterised by generalised thinning and globular protrusion of the cornea. It was first described as a separate clinical entity by Verrey in 1947.

Is corneal ectasia progressive?

What are the Symptoms of Corneal Ectasia? Corneal ectasia signs and symptoms are progressive as the cornea adopts a bulging shape. The most commonly reported are: Inability to fully correct vision to 20/20 with contacts or glasses.

How common is corneal ectasia?

Ectasia is a rare complication of corneal refractive surgery, occurring in just 0.04% to 0.6% of procedures.

Is corneal ectasia treatable?

Ectasia can usually be treated. Treatments for ectasia are similar to those used to treat a condition called keratoconus (another distortion of the eye’s shape). Thanks to advancements in technology, some patients with ectasia can now benefit from a procedure called corneal collagen cross-linking (CXL).
