Before surgery, your eye will be measured, these measurements help your Ophthalmologist select the proper lens implant for your eye. Your doctor will also discuss the various lens options available to you.
If you have had previous LASIK or other laser vision correction, you can still have cataract surgery. In planning for cataract surgery, provide your Eye M.D. with the vision correction prescription you had before LASIK, if possible. This information will help your Eye M.D. calculate the correct IOL prescription for you. Previous refractive surgery can make determination of the correct IOL more difficult and your vision presciption prior to refractive surgery can help the surgeon calculate the correct IOL power.
Medications and cataract surgery
If you are having cataract surgery, be sure to tell your ophthalmologist about all medications and nutritional supplements you are taking. If you currently use or have ever used alpha-blocker drugs for prostate problems, such as Flomax®, Hytrin®, Cadura® or Uroxatral® , tell your Eye M.D. These medications may prevent your pupil from dilating properly during surgery, leading to possible complications. If your surgeon is aware that you have had these drugs, he or she can adjust their surgical technique to adapt as needed, allowing for a successful cataract removal procedure. You should also tell your Eye M.D. about any other sedative medications you are taking.
To reduce the risk of infection from surgery, your ophthalmologist may prescribe antibiotic eyedrops for you to use one or two days before surgery.
The cataract surgery procedure
The most common procedure used for removing cataracts is called phacoemulsification. A small incision is made in the side of the cornea (the front part of your eye), where your Eye M.D. inserts a tiny instrument that uses high-frequency ultrasound to break up the center of the cloudy lens and carefully suction it out.
After the cloudy lens has been removed, the surgeon will replace it with an intraocular lens (IOL) implant made of plastic, silicone or acrylic. This new, clear lens allows light to pass through and focus properly on the retina. The IOL becomes a permanent part of your eye. In most cases, the IOL is inserted behind the iris, the colored part of your eye, and is called a posterior chamber lens. Sometimes, the IOL must be placed in front of the iris. This is called an anterior chamber lens. When the IOL is in place, the surgeon closes the incision. Stitches may or may not be used. After the surgery, your Eye M.D. usually places a protective shield over your eye.
