What is Presby-Fix™?

Presby-Fix™ is a procedure that restores near vision or "reading vision" and frees you from the constant frustrations of reading glasses. Presby-Fix™ uses the first non-intraocular microsurgical device to treat Presbyopia. The procedure is usually performed using the AcuFocus KAMRA™ Inlay. Often called “farsightedness” or “middle-age eyes,” Presbyopia is characterized by a slow, progressive loss of near vision, making reading difficult and eventually impossible without correction. By the time you reach your 40s, you will experience these symptoms, usually requiring the use of bifocals or reading glasses. Unlike nearsightedness (myopia,) presbyopia does not affect distance vision.

How is this procedure performed?

Presby-Fix™ consists of a laser microsurgical insertion of a 3.8mm ultra-thin disc into the cornea, in front of the iris. This disc is necessary only in the non-dominant eye. The procedure takes about 10 minutes. There should be little to no discomfort with the procedure.

When will I be able to return to work?

After you have been seen the day after surgery for a brief checkup, you should be able to return to normal activities. You will have additional post-op visits to monitor your healing. All patients adjust at different rates. Some patients will see improved near vision within a few days and some patients will need a few weeks to a few months or longer.

Am I a candidate for Presby-Fix™?

Presby-Fix™ is an option that can be recommended for patients ages 40 to 60 who use reading glasses. In many cases patients who have had previous LASIK surgery may also be candidates for Presby-Fix™. As with all vision correction procedures you will undergo a very thorough evaluation to determine if you are a good candidate for this procedure.

Is there any cleaning or maintenance with the Inlay?

No maintenance is required for the Inlay. It will not need to be changed in the future.

Is Presby-Fix™ reversible?

Yes. The KAMRA Inlay is surgically removable.

Presby-Fix™ Details

Presby-Fix uses the KAMRA inlay which sits in the first few layers of the eye known as the cornea. Smaller and thinner than a contact lens, the inlay is a mini-ring with an opening - or pinhole - in the center. This pinhole allows only focused light to enter your eye. The KAMRA inlay is placed in only one of your eyes, allowing you to see up close, while maintaining your distance vision in both eyes. Your non-KAMRA eye is left untouched. Working together, the eyes allow you to see near to far. This is unlike monovision laser vision correction, which corrects one eye for near and one eye for distance and does not last over time.
