what treatment options are there?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Corneal opacity can usually be treated.<br \/>\nHowever, the exact treatment method depends on factors such as the cause and severity. <\/span><\/p>\n<h3><b>Drug treatment  <\/b><\/h3>\n<p><span style=\"font-weight: 400;\">If the corneal clouding is caused by inflammation, treatment with medication may be considered.<br \/>\nEye drops containing cortisone are often used for this purpose.   <\/span><\/p>\n<h3><b>Surgical intervention<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Eye surgery (phototherapeutic keratectomy) is used if treatment with medication has not been successful or the corneal clouding has been caused by small injuries\/scarring.<br \/>\nA laser is used to remove the scarring and clouding.<br \/>\nHowever, this is only possible if the uppermost layers of the cornea are affected.  <\/span><\/p>\n<h3><b>Corneal transplantation<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">If the corneal clouding has progressed to such an extent that there is a risk of blindness, a corneal transplant (keratoplasty) is often the only promising treatment option.<br \/>\nIn keratoplasty, the cloudy cornea is removed and a donor cornea is inserted. <\/span><\/p>\n<p><b>Prevent corneal opacity<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Corneal opacities caused by injuries can be prevented by being careful in everyday life.<br \/>\nOtherwise, it is important to consult a specialist in good time if symptoms occur.<br \/>\nThe quicker the diagnosis is made, the easier it is to treat the opacity.    <\/span><\/p>\n<p><span style=\"font-weight: 400;\">A corneal opacity often develops gradually.<br \/>\nIf you experience visual disturbances, eye pain or a persistent foreign body sensation, it is always advisable to have the symptoms investigated.   <\/span><\/p>\n<h2><b>Frequently asked questions &amp; answers about corneal opacity<\/b><\/h2>\n<p><b>Can corneal opacity be cured?<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Corneal opacity can be treated well.<br \/>\nDepending on the cause of the corneal clouding, various treatment options are available: drug treatment, eye surgery (phototherapeutic keratectomy) and finally a corneal transplant. <\/span><\/p>\n<h3><b>How does corneal opacity manifest itself?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Corneal opacity can be visible externally.<br \/>\nIt is characterized by a white film over the eye.<br \/>\nHowever, this is only the case at an advanced stage.<br \/>\nInitially, those affected experience visual disturbances, eye pain or a foreign body sensation.<br \/>\nIf left untreated, corneal opacity can lead to blindness.    <\/span><\/p>\n<h3><b>Can a corneal injury heal on its own?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">If the corneal injuries are small and not deep, regeneration is possible.<br \/>\nHowever, scarring can also occur, which in turn promotes corneal clouding.<br \/>\nIt is always advisable to consult a doctor in the event of an eye injury.  <\/span><\/p>\n<hr \/>\n<div class=\"eyelaser-guide-cta\">\n<h3>Sharp vision without glasses \u2013 EyeLaser Vienna &amp;
