During cataract surgery, the lens of the eye is removed and replaced with an intraocular lens, which is also known as an IOL. The FDA recently approved advanced versions of IOLs, which means that patients in Boulder and Denver, CO who undergo cataract surgery now have more choices than ever when it comes to improving their vision.
Some types of IOLs are intended to enhance distance vision, which means that patients who have these lenses inserted may still need reading glasses. Others provide good near and far vision and can eliminate the need for glasses altogether. Still others provide excellent daytime vision, but may result in a glare that makes driving at night difficult. The type of lens inserted into the eye after cataract surgery can depend on factors such as a patient's overall vision, presence of eye disease, or astigmatism.
People in Boulder and Denver, CO who have near perfect vision may not be the right candidates for Multifocal IOL, since they would likely receive little benefit from them. These patients may be given presbyopia-correcting IOLs instead, as these lenses tend to help both nearsighted and farsighted individuals. Patients who are nearsighted in one eye and farsighted in the other may need to have different IOL lenses implanted in each eye. Those who have astigmatism may need to have Toric IOLs, as these lenses are specially designed to treat this condition.
After having cataract surgery at BoulderEyes/Beyer Lasik, many patients have improved vision, yet notice visual distortion from time to time. These visual distortions are usually more profound at night, resulting in a great deal of glare or the appearance of halos near sources of light. Even if a patient no longer needs to wear glasses, regular eye examinations are important to rule out changes in vision that could result in needing corrective eyewear. A regular exam can also detect changes or damage to the IOLs, which could require surgery to correct.
