FAQs AND FACTS

This procedure is not yet available to the general public. The following information addresses most questions about the device and the results obtained to date.

MOST FREQUENTLY ASKED QUESTIONS:

Q. What is involved in this procedure?

A. A small vacuum cup smaller than a thimble is put in contact with the cornea of the eye and a vacuum is applied to the cup through a small flexible tube for a few minutes.

Q. Who is a candidate for this procedure?

A. The procedure will probably be indicated for all myopes, hyperopes may also be future candidates. More than one third of the U.S. population is myopic and more than half in Asian countries.

Q. How does the procedure correct vision?

A. The vacuum produces a suction force that slightly changes the curvature of the cornea. The reduction of the curvature of the cornea corrects myopia or nearsightedness.

Q. Is this a painful procedure?

A. The only anesthesia used is topical (eye drops). There is little discomfort. There are no injections, IVs, sutures or bleeding. Patients walk out and go home on their own. There is no pain during the procedure. In the eight hours after the procedure some patients need to take oral analgesics.

Q. How long does the procedure take?

A. About ten minutes.

Q. What kind of vision can be expected after a successful treatment?

A. The same or better vision that was attained with your glasses prior to the procedure.

Q. What are the risks?

A. There appears to be no significant risks. It is clearly safer than surgical methods, we have not detected any long-term risks.

Q. What will be the cost of the procedure?

A. Significantly lower than current methods, such as laser keratectomy and LASIK. In the clinical trial phase the treatment is free.

Q. Is the procedure done in the hospital or in the office?

A. This is a very simple, non-invasive out-patient procedure.

Q. Has the procedure been tried on human corneas?

A. The procedure has been used successfully on human and on animal corneas. Clinical trials started in several centers around the world.

Q. Can too much suction pressure be applied, thus causing damage to the eye?

A. The maximum vacuum pressure that is normally applied does not cause any damage to the cornea and it does not increase the intraocular pressure during the treatment.

Q. What are the long-term effects of plastically deforming the human cornea?

A. As in any new procedure the long-term effects are unknown. However, no adverse effects have been noticed in subjects treated.

Q. How can one become a candidate for free clinical trials?

A. Just send your name, age, eyeglass prescription and a reliable and complete means to contact you. We will include you in our list of potential candidates and will contact you when appropriate.
