Understanding IOLs
IOLs are medical devices that can be used to replace the natural lens when cataracts develop. Before IOLs became popular, patients who had their cataracts removed had to wear special contact lenses or very thick prescription eyeglasses to see clearly following their procedure. This is because the lens was not replaced, just removed. However, with the integration of IOLs in cataract surgery, patients have options to restore their vision without vision correcting lenses. IOLs are placed into the eye and provide amazing results for patients who have struggled with cataracts.
What IOLs are available?
Below are the four common IOLs used after cataract removal for patient consideration:
- Aspheric IOLs – these lenses are different than traditional IOLs which have a spherical design. While ideally the eye should be uniformly curved, this is rarely the case. An aspheric IOL fits better on an eye that does not have perfect curvature and match closer to the shape of the natural eye lens. This provides sharper vision, especially for patients who have trouble seeing in low-light conditions or those who have large pupils.
- Toric IOLs – patients with an astigmatism in the eye may benefit from toric IOLs. In addition, these lenses can address nearsightedness or farsightedness. These IOLs have temporary markings that make it easier for the doctor to place them properly, rotating them to ensure proper astigmatism correction.
- Accommodating IOLs – accommodating IOLs are used instead of monofocal lenses, which still required patients to wear eyeglasses or contacts when reading or using a computer. The accommodating IOLs work by expanding the range of clear vision and eliminating the need for extra vision correction for daily tasks.
- Multifocal IOLs – patients who would otherwise need bifocals or trifocals can utilize multifocal lens for vision correction following cataract surgery. These can allow patients to avoid the use of multifocal reading glasses or eyeglasses after their cataract treatment.
