Lens Implants Vision Correction Procedure

Approximately 30% of patients who are interested in Laser Vision Correction are not candidates. There are several reasons for this:

  1. Thin corneas
  2. Irregularly-shaped corneas
  3. Significant dry eye condition
  4. Level of myopia (nearsightedness) or hyperopia (farsightedness) that exceeds the laser vision correction range
  5. Correction needed only for reading vision (presbyopia)

For patients with these conditions Kelly Laser Center offers Implant Vision Correction. Implants are basically divided into two categories: 1) Phakic Implants and 2) Non-Phakic Implants or Clear Lens Extraction. Phakic means that the natural lens remains in the eye, and non-phakic means that the natural lens has been removed. Non-phakic is often referred to as “pseudophakic” and, in effect, the “pseudophakic” lens takes the place of the natural lens. The choice of implant used depends upon the underlying condition to be treated and the patient’s age.
Unlike Laser Vision Correction, which alters the surface of the eye (cornea), Implant Vision Correction corrects vision with the placement of a synthetic lens inside the eye. If the implant is placed in the eye with the eye’s natural lens still in place, the implant is called a phakic implant; if the implant is placed after the eye’s natural lens is removed, the implant is called a non-phakic or pseudophakic implant.  Implant surgery utilizes techniques and materials similar to those used for cataract surgery.  As such, the general technology has a successful record in tens of millions of eyes over 25 years.  Please note that Implant Vision Correction may be combined with Laser Vision Correction to provide extremely precise refractive corrections.

During your personalized one-on-one consultation, Dr. Kelly will discuss both the benefits and risks of implant surgery and the type of implant best suited to your condition.

A) Phakic implants

They are primarily used to treat high levels of myopia, generally over 10 diopters. They may be used for lower levels of myopia in situations where the cornea is thin and/or irregular in shape.  Phakic implants are actually divided into two groups: those that are placed in front of the colored part of the eye (iris), and those that are placed behind the iris. The lens placed in front of the iris is called the Verisyse lens, and the one placed behind the iris is called the Visian lens.  Many measurements of the eye are taken during the examination process to determine suitability and candidacy for implantation.  For this reason it is important that patients discontinue contact lens use for a week prior to their consultation.

The best candidates for the Visian lens are between 20 and 50 years old with higher levels of myopia and healthy eyes.  It is inserted through a tiny incision and is placed behind the iris in a structure known as the ciliary sulcus without the need for stitches.  It very seldom can be felt and requires no maintenance. The cosmetic appearance is excellent—the implant can not be seen by you or any other non-professional observer.

The Verisyse implant has a 20-year track record worldwide with many of thousands lenses inserted.  Like the Visian implant, the best candidates are healthy individuals with stable prescriptions age 20 to 50 who have higher levels of myopia.  More than 50% of Verisyse patients saw better after surgery than with glasses or contacts beforehand. As with implant vision correction in general, the Verisyse lens is reversible. In the unlikely event a patient is not satisfied with his or her vision, the implant can be removed.

Complications are rare with a small percentage of patients reporting night glare. Some other rare complications can be cataract development, inflammation, and infection. When comparing LASIK to Verisyse implants, the majority of highly myopic patients who had LASIK performed on one eye and a Verisyse implant inserted in the other eye preferred their quality of vision with the Verisyse eye. Safety factors were equal regarding the two methods.

Procedure Described

The insertion technique takes approximately 20 minutes and is performed on an out-patient basis. Patients are awake during the insertion and report very little to no discomfort while under the influence of a local anesthetic.
If the eye changes after implantation, a patient can use a mild glasses or contacts prescription or the implant can be removed or exchanged for a new power lens, just as glasses or contact lenses may need to be changed over time. Also Laser Vision Correction can be combined with the Verisyse and Visian Lens to optimize vision.  Periodic examinations to assess the ongoing health of the eye are required.
Patients are usually back to work the next day.  Implant surgery is performed on one eye at a time with a separation of a few weeks between eyes.  This separation is necessary to monitor healing and satisfaction.

B) Non-phakic implants/Clear Lens Extraction/Pseudophakic implants

These implants are primarily used to correct higher levels of hyperopia (generally over 5 diopters) and presbyopia. See illustration. Like the phakic implant procedure described above, the non-phakic/pseudophakic implant/clear lens extraction procedure is similar with respect to technology, results, safety, and recovery.  The main difference is that the natural lens is first removed before placing the implant and the implant is placedwithin the lens capsule rather than in structures farther in front of the eye.

The most recent FDA approval in Implant Vision Correction has been the exciting ReSTOR® Lens.

Until now most patients more than 45 years of age have needed glasses for up close-vision regardless of whether they underwent vision correction surgery. This is because of presbyopia. Now it is possible to eliminate or dramatically reduce your dependence on both distance and reading glasses or contact lenses. This is in addition to never developing the aging change of the eye known as a cataract.

There is breakthrough technology whereby an implant can restore a range of distance vision for a person, near through distance, while minimizing visual disturbances such as nighttime glare and halos.  This is in contrast to most implants that correct only distance vision. The technology is known as apodization and diffraction and has been used in microscopes and telescopes to improve image quality. The ReSTOR lens can provide lifestyle vision for the majority of active patients. In studies 80% of ReSTOR IOL patients never needed to wear glasses for any activity.

Studies demonstrated that in patients who had ReSTOR lenses in both eyes, no glasses were needed for driving, reading, using the computer, applying makeup, or shaving in the vast majority of patients. Studies also demonstrated that ReSTOR patients were so satisfied with their vision that 94% indicated they would have the procedure again.

The material that the ReSTOR lens is made of has been implanted in more than 23 million eyes since 1991. Only 5% of people had very noticeable nighttime halos, and some grew accustomed to these visual disturbances.  Some continued to notice them indefinitely. A small percentage noticed increased difficulty distinguishing objects from a dark background and should take extra care when driving at night. As with any surgical procedure, there are inherent risks, and your result can not be guaranteed. Feel free to discuss with your surgeon. Please request a Patient Information Booklet. Feel free to visit on www.acrysofrestor.com to learn even more about the ReSTOR lens.
Some patients may require laser enhancements in the office after the ReSTOR lens in placed. There is no fee for this.  Please discuss this possibility with the doctors at Kelly Laser Center.  Some patients may require the ReSTOR lens to be exchanged for another power ReSTOR lens or a different type of lens altogether.

Dr. Kelly and the Kelly Laser Center staff will address more specific aspects of the procedure at the time of your consultation. If you have been told that you are not a LASIK candidate, please contact Dr. Kelly to schedule a thorough eye exam to determine if Implant Vision Correction may be right for you.
