What Are the Steps in the IMT Procedure?

If you have answered yes to all questions in the Patient Questionnaire, please request a screening appointment with Dr. Grant Comer by calling Wendy Mrdjenovich, program coordinator, at 734-232-8404.

Eye examination and pre-training

As a first step in this treatment program, you will have a thorough medical eye examination by a Kellogg retina specialist who will determine whether you are a good candidate for surgery based on your retinal exam. Your doctor will also explain the benefits and risks of the treatment program. If you appear to be a good candidate, you will be referred to Kellogg’s Low Vision specialists.

Our Low Vision specialists will perform additional testing. They will also help you use an external telescope simulator to help you understand how your vision will change after the IMT is implanted.  This will help you know whether you are likely to adjust to vision with the IMT.

In addition they will describe the training you will need after the implant to become accustomed to your new vision. 

The surgical procedure

A Kellogg cornea surgeon will review the procedure with you, again discussing the potential risks associated with the implant.  The procedure involves removing the eye's natural lens and replacing it with the tiny telescope implant developed by CentraSight. This is an outpatient procedure, meaning it does not require a hospital stay. You will return home the same day.  The telescope is very small, does not protrude from your eye, and is barely noticeable.

Learning to use your new vision

Our Low Vision specialists will work with you to help you adapt to your new vision. With the implanted eye you will have highly magnified vision, but no peripheral vision. You will use your other eye for peripheral vision.  Our specialists will prescribe new eyeglasses and begin to teach you the skills that will help you become accustomed to the difference in vision between your eyes.

For example, you will learn to use the untreated eye for navigating and walking around, which require peripheral vision.  For the magnified eye, which will allow you to have central vision, you will learn techniques for focusing on objects, tracking moving objects, and tracing a path between two objects.
