Refractiemethoden

Refractiemethoden refer to the various techniques used in the field of optics and visual sciences to modify or correct the refractive properties of the eye or optical systems. These methods are primarily employed to treat refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), astigmatism, and presbyopia, thereby improving visual acuity without the need for corrective lenses.

In ophthalmology, common refractiemethoden include surgical procedures like LASIK (Laser-Assisted In Situ Keratomileusis), PRK (Photorefractive Keratectomy), and SMILE (Small Incision Lenticule Extraction). These techniques involve reshaping the cornea with laser technology to alter its refractive power, enabling light to focus properly on the retina. Other methods include intracorneal ring segments and implantable lenses, which physically modify or supplement the eye's structure.

Non-surgical refractiemethoden include contact lenses and eyeglasses, which adjust the light path before it enters the eye. Additionally, orthokeratology employs specially designed rigid contact lenses worn overnight to temporarily reshape the cornea, providing clear vision during the day.

The choice of refractiemethoden depends on factors such as age, corneal thickness, degree of refractive error, and patient preference. Advances in laser technology and biomaterials continue to enhance the safety and efficacy of refractive corrections, making these methods widely accessible worldwide.

Overall, refractiemethoden aim to reduce dependency on corrective devices, offering improved quality of life for individuals with refractive errors through minimally invasive or non-invasive approaches.
