Synskorrigerende

Synskorrigerende refers to measures or devices that improve visual acuity by correcting refractive errors of the eye. In ophthalmology and optometry, the term encompasses both non-surgical and surgical interventions designed to reduce dependence on eyeglasses or contact lenses or to restore functional vision.

Refractive errors include myopia, hyperopia, astigmatism, and presbyopia. Non-surgical examples are eyeglasses and contact lenses—soft lenses, rigid gas-permeable lenses, and orthokeratology lenses worn overnight to temporarily reshape the cornea.

Surgical options include laser refractive surgery (LASIK, PRK, SMILE), implantable contact lenses (ICL), and refractive lens exchange. For presbyopia, multifocal or accommodating intraocular lenses may be used. Orthokeratology can also be considered vision-correcting for selected cases.

Effectiveness and safety: Most procedures provide significant improvements in uncorrected vision, though results depend on individual factors such as refractive error and corneal thickness. Potential risks include dry eye, glare or halos, infection, over- or under-correction, and, rarely, corneal ectasia. Long-term stability varies by method.

Selection and counseling: A comprehensive preoperative assessment is essential to determine eligibility, ocular health, and realistic expectations. Age, pregnancy, diabetes, and certain eye conditions may affect suitability. Glasses or contact lenses continue to be viable alternatives or adjuncts when appropriate.

Etymology: The term combines elements meaning sight and correction in Scandinavian languages, used to describe vision-correcting methods broadly.
