Eye implants, most commonly intraocular lenses (IOLs), are artificial lenses placed in the eye to replace the natural lens or provide a new focusing element. They are used to correct vision problems like cataracts, myopia, and astigmatism, and can be implanted either during cataract surgery or through other refractive procedures. There are different types of IOLs, including monofocal and multifocal, that address various vision needs.
What are eye implants?
- Function: IOLs are clear, artificial lenses that take over the focusing function of the eye's natural lens, directing light onto the retina.
- Purpose: They are most often used to replace the cloudy lens during cataract surgery but can also be implanted in people with other vision problems through procedures like Refractive Lens Exchange.
- Types:
- Monofocal: Provide a single, fixed viewing distance, meaning glasses may still be needed for other distances.
- Multifocal: Can correct for multiple distances, reducing dependence on glasses, though some patients may still require them for certain tasks.
- Toric: Specifically designed to correct astigmatism.
- Placement: They are typically made of a flexible, foldable material and are about one-third the size of a dime. They are either implanted as a replacement for the natural lens or as an additional lens placed behind the cornea (phakic IOL).
Recovery and recovery
- IOL implantation is often a quick procedure, and patients can usually go home the same day.
- Vision often improves significantly within a day or two, and many daily activities can be resumed.
- You may need to wear an eye shield while sleeping and must avoid getting soap and water in your eyes for a period.
- Your doctor will prescribe eye drops and schedule follow-up appointments to monitor your recovery.
- Adherence to your doctor's post-operative instructions is crucial for proper healing.
