class=\"translation-block\"><a href=\"https:\/\/visionlaser.ch\/en\/trans-prk\/\" target=\"_blank\" rel=\"noopener\">PRK<\/a> is a type of laser eye surgery.\n PRK stands for photorefractive keratectomy.<\/p>\n<p>It helps people see better without glasses or contact lenses.<\/p>\n<p class=\"translation-block\">PRK was one of the first laser eye treatments.\n It is still used today and works very well for many people.<\/p>\n<h3><strong>What vision problems does PRK treat?<\/strong><\/h3>\n<p>PRK can correct common vision problems, such as:<\/p>\n<ul>\n<li>short-sightedness (myopia)<\/li>\n<li>long-sightedness (hyperopia)<\/li>\n<li>astigmatism<\/li>\n<li>presbyopia<\/li>\n<\/ul>\n<p>These problems make it hard to see clearly.<\/p>\n<h3><strong>How does PRK work?<\/strong><\/h3>\n<p class=\"translation-block\">PRK reshapes the cornea.\n The cornea is the clear front part of the eye.<\/p>\n<p class=\"translation-block\">A laser is used to gently change its shape.\n This helps light focus better on the retina.<\/p>\n<h3><strong><h3><a href=\"https:\/\/visionlaser.ch\/en\/correction-de-la-vision-trans-prk-a-quoi-sattendre-du-debut-a-la-fin\/\" target=\"_blank\" rel=\"noopener\"><strong>What happens during PRK surgery?<\/strong><\/a><\/h3><\/strong><\/h3>\n<p>PRK is a short and safe procedure.<\/p>\n<p>During the treatment:<\/p>\n<ul>\n<li>numbing eye drops are used<\/li>\n<li>the surface layer of the eye is gently removed<\/li>\n<li>a laser reshapes the cornea<\/li>\n<li>a soft contact lens is placed on the eye<\/li>\n<\/ul>\n<p>The treatment usually takes only a few minutes.<\/p>\n<h3><strong>Does PRK hurt?<\/strong><\/h3>\n<p>You do not feel pain during the surgery.\n Your eye is numb.<\/p>\n<p>You may feel:<\/p>\n<ul>\n<li>soreness<\/li>\n<li>light sensitivity<\/li>\n<li>watery eyes<\/li>\n<\/ul>\n<p>This usually lasts a few days.<\/p>\n<h3><strong><h3><a href=\"https:\/\/visionlaser.ch\/en\/combien-de-jours-de-repos-sont-necessaires-apres-une-operation-des-yeux\/\" target=\"_blank\" rel=\"noopener\"><strong>How long does recovery take?<\/strong><\/a><\/h3><\/strong><\/h3>\n<p>Recovery after PRK is slower than some other laser treatments.<\/p>\n<p>Most people:<\/p>\n<ul>\n<li>rest for a few days<\/li>\n<li>return to work after about one week<\/li>\n<li>see vision improve over several weeks<\/li>\n<\/ul>\n<p>Full vision results can take a few months.<\/p>\n<h3><strong>Who is PRK suitable for?<\/strong><\/h3>\n<p>PRK may be a good option if:<\/p>\n<ul>\n<li>you have thin corneas<\/li>\n<li class=\"translation-block\">you are not suitable for <a href=\"https:\/\/visionlaser.ch\/en\/lasik-femtoseconde\/\" target=\"_blank\" rel=\"noopener\">LASIK<\/a><\/li>\n<li>you play contact sports<\/li>\n<li>you want a proven treatment<\/li>\n<\/ul>\n<p>Only an eye exam can confirm this.<\/p>\n<h3><strong>What are the benefits of PRK?<\/strong><\/h3>\n<p>PRK has many benefits:<\/p>\n<ul>\n<li>no corneal flap is created<\/li>\n<li>long-term stable results<\/li>\n<li>suitable for more eye types<\/li>\n<li>safe and effective<\/li>\n<\/ul>\n<h3><strong>Are there any risks?<\/strong><\/h3>\n<p>All medical procedures have some risks.<\/p>\n<p>Possible side effects include:<\/p>\n<ul>\n<li>dry eyes<\/li>\n<li>blurry vision during healing<\/li>\n<li>glare at night<\/li>\n<\/ul>\n<p>Your surgeon will explain everything clearly.<\/p>\n<h3><strong><h3><a href=\"https:\/\/visionlaser.ch\/en\/lasik-ou-prk\/\" target=\"_blank\" rel=\"noopener\"><strong>PRK vs LASIK: what is the difference?<\/strong><\/a><\/h3><\/strong><\/h3>\n<p>PRK and LASIK both improve vision.<\/p>\n<p>The main difference is:<\/p>\n<ul>\n<li>PRK removes the surface layer<\/li>\n<li>LASIK creates a small flap<\/li>\n<\/ul>\n<p>PRK has a longer recovery time, but similar results.<\/p>\n<h3><strong>Why choose <a
