What are Premium Multifocal Lenses (IOL)? Who can benefit from them? How are these lenses different from traditional ones? Premium IOLs are divided into two types: [Multifocal Lenses](https://www.alliedeye.com/?hsLang=en) and [Toric Lenses](https://www.alliedeye.com/?hsLang=en). Please visit those pages for information on each type. What are the risks of cataract surgery? As with any surgery, cataract surgery poses risks, such as infection and bleeding - both are very rare. Before cataract surgery, you may need to temporarily stop taking certain medications that increase the risk of bleeding during surgery. After surgery, you must keep your eye clean, wash your hands before touching your eye, and use the prescribed medications to help minimize the risk of infection. Serious infection can result in loss of vision. Cataract surgery slightly increases your risk of retinal detachment. Other eye disorders, such as high myopia (nearsightedness), can further increase your risk of retinal detachment after cataract surgery. Patients taking Flomax should inform their surgeon before cataract surgery, because it has an effect on pupil size. What happens before surgery? A week or two before surgery, we will perform some tests on your eyes. These tests may include measuring the curve of the cornea and the size and shape of your eye. This information helps us choose the right type of implant. There are options for different types of implants available. See Premium Lenses. You may be asked not eat or drink anything 12 hours before your surgery. What happens during surgery? At our center, drops will be instilled into your eye to dilate the pupil. The area around your eye will be washed and cleansed. The operation usually lasts 15 - 20 minutes and is almost painless. Many choose to stay awake during surgery. Others may need to be sedated for a short time. If you are awake, you will have an anesthetic to numb the nerves in and around your eye. After the surgery, a patch may be placed over your eye. You will be monitored for 15 to 30 minutes after surgery and then discharged. What happens after surgery? Your eye(s) may be blurred and watery after surgery. There may be light sensitivity, as well. If you have discomfort, we can suggest treatment. After one to two days, moderate discomfort should disappear. For a few days after surgery, you will need to use eyedrops to help healing and decrease the risk of infection. You will receive detailed instructions on using your eyedrops. You will need to wear an eye shield (or eyeglasses) to help protect your eye. Avoid rubbing or pressing on your eye. When you are home, try not to bend from the waist to pick up objects on the floor. Do not lift any heavy objects. You can walk, climb stairs, and do light household chores. In most cases, healing will be complete within eight weeks. We will schedule a follow-up exam to check on your progress. ### PATIENT RESOURCES ### QUICK LINKS ### Contact Us Allied Eye 7405 Shallowford Rd.
