Cataract surgery is an effective and safe procedure to replace the inner lens of the eye which has become cloudy with an artificial lens that will enable the person to see clearly again.
Cataract is a common eye condition that occurs due to various reasons, but the main cause is age. The older a person gets the more cloudy the lens inside their eye becomes which can lead to a milky white color of the lens. The less transparent the lens becomes, the more it causes impaired vision and sometimes glare from looking at lights. The good news is that there is very effective treatment for this condition and that is cataract surgery followed by a lens replacement, known as an intraocular lens or IOL. If you notice any changes in your vision, especially if you are around age 60 or above, please schedule an appointment with your eye doctor to check your eye health and to find out if you have cataract.
Cataract surgery is generally an outpatient procedure, meaning it does not require an overnight stay at the hospital and it often takes an hour or less. It is a very common and highly successful surgery which removes the part of your lens inside of your eye that has become cloudy. The most contemporary approach to this procedure is to leave inside your eye the outer sac layer of the lens in which your lens sits. Preserving this part of the sac allows for successful implantation of a tiny artificial lens which is about a third of the size of a dime and it’s called the IOL. This new intraocular lens does not require any maintenance, you don’t see or feel it and it simply becomes part of your eye, enabling you to see so much clearer than you were seeing prior to cataract surgery.
Cataract surgery is most often a non-emergency procedure. A person may have cataract for many years before deciding to go through with the operation. The main indication for surgery is when the cataract starts making day to day functions more difficult. In other cases, if cataract is interfering with other pre-existing eye conditions, one might be advised to have cataract surgery.
In order to make sure that you are a proper candidate for cataract surgery, you will first have a very thorough eye exam which will check your visual acuity, the health of your eyes, and various other necessary measurements. You will be asked to share a full medical background, including all medications you are taking and if you have any allergies. Your eye doctor will help you decide if cataract surgery is the right step for you.
If you decide to get cataract surgery, a very important step before the operation is figuring out which intraocular lens will best suit your needs. The natural lens inside of our eyes is responsible for performing the incredible task of providing clear vision at different distances which requires the lens to bend in different ways in order to reflect the incoming light in a way that enables us to see. During cataract surgery, your lens is removed and gets replaced with an artificial IOL. Like glasses and contact lenses, IOLs are available in different powers. The eye doctor will also measure the curvature of your cornea and the length of your eye in order to provide the best fit for your IOL.
Your eye doctor will explain to you the various types of artificial lenses that you can choose from and together you will decide which kind best suits your lifestyle and can fit your budget. There are different kinds of materials that the IOL is made from such as plastic, silicone, or acrylic. Some artificial lenses have a special feature of being able to fold which provides flexibility and some IOLs block ultraviolet rays from the sun. Today, there are so many different types of optics that the intraocular lenses can provide, these include:
After all preparations are made before the operation, you will also be given medicine to take in the form of eye drops for a few days leading up to the surgery. Your eye will be numbed right before the operation and you will be given a drug that will help you relax. During the procedure, you might see light but you shouldn’t feel anything, other than gentle pressure. During the surgery, your cloudy natural lens will be removed and replaced with the artificial IOL. This procedure does not require stitches and your eye can heal on its own. Most often, you can go home in less than an hour but someone else must drive you. Any procedure has a risk of complications but cataract surgery is not considered to be a risky one. It is possible to have post-op complications but the chances are very low and the eye doctor will do everything possible to avoid that and when necessary, to guide you through it.
It takes around 8-12 weeks for the eye to fully heal, but many people enjoy the benefits of being able to see so much clearer than they were seeing prior to surgery anywhere from a few hours after surgery to a week or two post-op. It is recommended that you wear sunglasses during these weeks and that you sleep with an eye shield. Your eye doctor will prescribe medicated eye drops that you will use for a number of weeks.
We are fortunate to be living in a time period where there is such a successful procedure available to provide clear vision to people who have cataract. Cataract surgery replaces your cloudy lens inside of your eye with an artificial lens, known as an IOL, that provides sharp vision and allows you to enjoy daily life with clear eyesight.
