Nägemisimplantatsioonid

Nägemisimplantatsioonid, also known as intraocular lenses (IOLs), are surgical devices used to replace the natural lens of the eye, which may have become cloudy or damaged due to conditions such as cataracts. These implants are typically made from materials like silicone, acrylic, or other biocompatible substances. The procedure involves removing the cloudy lens and replacing it with an IOL, which can restore clear vision and improve the quality of life for patients.

There are several types of IOLs, each designed to correct different types of vision problems. Monofocal IOLs correct vision at one distance, usually for distance vision. Multifocal IOLs correct vision at multiple distances, providing clear vision for both near and far objects. Toric IOLs are used to correct astigmatism, a condition where the cornea or lens is irregularly shaped. Accommodating IOLs, also known as phakic IOLs, are implanted in front of the natural lens and do not replace it, allowing the eye to adjust focus like a normal eye.

The surgery to implant an IOL is typically performed under local anesthesia and takes about 15-30 minutes. Recovery time varies but usually involves a few days of rest and medication to reduce inflammation. Most patients experience improved vision within a few days to a few weeks post-surgery. Complications are rare but can include infection, retinal detachment, or glare from the implant.

Nägemisimplantatsioonid have significantly improved the lives of many patients by restoring their vision and reducing the need for glasses or contact lenses. Advances in technology continue to enhance the effectiveness and safety of these implants, making them a valuable option for those with cataracts or other lens-related conditions.
