<p>CSV import</p> <p><b>New page</b></p><div>&#039;&#039;&#039;Post-LASIK ectasia&#039;&#039;&#039; is a rare but serious complication that can occur after [[LASIK]] surgery. It is characterized by a progressive thinning and bulging of the [[cornea]], which can lead to vision loss. <br /> <br /> ==Etiology==<br /> <br /> The exact cause of post-LASIK ectasia is not fully understood. However, it is believed to be related to the weakening of the corneal structure following the removal of corneal tissue during LASIK surgery. Other risk factors may include a pre-existing condition known as [[keratoconus]], high [[myopia]], and a thin or irregular cornea.<br /> <br /> ==Symptoms==<br /> <br /> Symptoms of post-LASIK ectasia may not appear until months or even years after the LASIK procedure. They can include progressive [[myopia]], irregular [[astigmatism]], and an increase in higher-order [[aberrations]]. These symptoms can result in blurred or distorted vision, increased sensitivity to light, and difficulty seeing at night.<br /> <br /> ==Diagnosis==<br /> <br /> Diagnosis of post-LASIK ectasia is typically made through a comprehensive eye examination, including corneal topography and [[pachymetry]]. These tests can help to identify changes in the shape and thickness of the cornea that are characteristic of ectasia.<br /> <br /> ==Treatment==<br /> <br /> Treatment options for post-LASIK ectasia are limited and can depend on the severity of the condition. They may include the use of rigid gas permeable [[contact lenses]] to improve vision, [[collagen cross-linking]] to strengthen the cornea, or in severe cases, a [[corneal transplant]].<br /> <br /> ==Prevention==<br /> <br /> Prevention of post-LASIK ectasia involves careful patient selection for LASIK surgery, including thorough preoperative screening to identify potential risk factors. In patients with a high risk of developing ectasia, alternative refractive surgery procedures may be considered.<br /> <br /> ==See also==<br /> <br /> * [[LASIK]]<br /> * [[Keratoconus]]<br /> * [[Corneal topography]]<br /> * [[Pachymetry]]<br /> <br /> [[Category:Eye surgery]]<br /> [[Category:Ophthalmology]]<br /> [[Category:Medical conditions]]<br /> {{Eye-disease-stub}}<br /> {{Medicine-stub}}</div>
