Relief from Dry Eye and Poor Vision

relief from dry eye and poor vision

Dr. Tiffani Methvien specializes in fitting the Custom Stable, a scleral contact lens that is specially designed to significantly reduce burning, dryness, and irritation. This unique lens creates a natural chamber of moisture between the lens and cornea that smooths out corneal imperfections while acting as a barrier against environmental challenges such as wind, air conditioning, and heat. In addition, the Custom Stable’s incredible refractive properties can restore vision for patients suffering vision loss due to keratoconus, corneal transplants, soft lens intolerance, and other complications. Contact Dr. Tiffani Methvien today to get fit in the Custom Stable and significantly improve your quality of life.

Do you suffer from Keratoconus or Corneal Ectasia?

keratoconus

Anita Miedziak, M.D. of the Princeton Eye Group in Princeton has conducted years of clinical research trials to study the effectiveness of an innovative treatment to stop or slow the progression of Keratoconus and Corneal Ectasia. Dr. Miedziak is one, of only two, principal investigators in FDA cross-linking trials in New Jersey. She has vast experience in arresting the progression of Keratoconus and Corneal Ectasia and is now the only ophthalmologist in this area performing the procedure.

Princeton Eye Group has acquired the KXL by Avedro Inc. – the only FDA approved cross-linking system in the USA – and is the only area provider to offer this technology. For more information or to schedule an appointment with Dr. Miedziak, please call 609-924-9200.

What is Keratoconus?

Keratoconus is a non-inflammatory eye condition in which the cornea progressively thins and weakens, altering its round dome shape to a cone-like bulge which can result in significant visual impairment.

What is Corneal Ectasia?

The term Corneal Ectasia refers to a group of conditions, including Keratoconus. In some cases, Corneal Ectasia can occur after a patient has undergone refractive surgery (LASIK or PRK), where irregular astigmatism has developed. In both instances, visual impairment can increase as the cornea continues to bulge.

Symptoms

Individuals in their late teens or early twenties may experience the first signs of Keratoconus. The condition may progress for 10-20 years before stabilizing or slowing down. Each eye may be affected differently. In the early stages of Keratoconus, people might experience:

  • Glare
  • Distortion of vision
  • Ghost images

What is Cross-Linking?

Corneal collagen cross-linking is a medical procedure that combines the use of ultra-violet (UV) light and riboflavin (vitamin B2) eye drops. Corneal cross-linking:

  • Arrests progressive stretching of the corneal collagen
  • Creates new corneal collagen cross-links
  • Results in a shortening and thickening of the collagen fibrils
  • Leads to the stiffening of the cornea

New Stitchless Advances in Corneal Transplantation Surgery Speed Recovery

Dr. Anita I. Miedziak, Director of Cornea Services at the Princeton Eye Group, performs the most advanced techniques in corneal transplantation with reduced risk of astigmatism and shorter recovery times.

DSEK (Descemet Stripping Endothelial Keratoplasty) is a new option in corneal surgery. DSEK is a partial thickness corneal transplant. It is offered to patients with persistent corneal swelling due to Fuchs dystrophy, failed corneal transplants, swelling induced by prior eye surgery or the aging process of the eye. In those cases DSEK can substitute traditional corneal transplantation and is performed without sutures. The advantages of the DSEK procedure include:

Significantly faster visual recovery since no additional astigmatism is induced (2-3 months vs. over a year with standard corneal transplantation)

Chances of corneal rejection are markedly reduced • Only the diseased layer of tissue is removed instead of the entire cornea –leaving the eye stronger –maintaining its normal resistance to injury

DSEK can be combined with cataract surgery

DSEK is performed on an outpatient basis under local anesthesia and takes approximately 30 minutes. The DSEK procedure removes the unhealthy endothelial cell layer and replaces it with healthy cells from a donor cornea. In order to make the new tissue adhere to the back of the old cornea, an air bubble is used to fill the front part of the eye for an hour after surgery. A follow-up visit is required the day after surgery.

Patients can return to their normal activities within two weeks with the exception of swimming. An antibiotic eye drop is used for two weeks and a steroid drop is used for at least a year to prevent graft rejection. Rejections are rare and treatable.

IEK (IntraLase Enabled Keratoplasty) is a new revolutionary way of performing full thickness corneal transplantation procedure utilizing a laser. The IntraLase laser is used to replace the diseased cornea in a precise fashion thus reducing postoperative astigmatism and corneal surface irregularity speeding up the visual rehabilitation. The IntraLase laser procedure also reduces the need for stitches making recovery both easier and faster.

Seeing the World Through Rose Colored…Contacts?!

Although not rose colored at all, the new Rose K™ contact lens is a welcomed advance in the treatment of Keratoconus.

Picture viewing the world as if you’re looking through a car windshield in a driving rainstorm – that’s how uncorrected vision looks to people with advanced Keratoconus. Keratoconus is characterized by a gradual thinning of the cornea, which alters its normal round shape to that of a cone. This bulging can severely affect a person’s ability to read, watch TV and see clearly enough to drive.

Keratoconus is generally diagnosed in young people around the age of puberty but can also be first diagnosed in people in their 40s and 50s. It initially presents as slightly blurred, distorted vision with a sensitivity to light and glare. It is a condition that progresses slowly and can, in the beginning stages, be easily corrected with glasses. As the condition advances, gas permeable (GP) contact lenses are often the best method to correct vision.

The complex geometry of the Rose K™ lens allows it to act in concert with the conical shape of the cornea throughout most stages of Keratoconus. As a result, the Rose K™ lens offers better comfort and optimum visual acuity. Its “breathable” material allows oxygen to flow directly through to the cornea proving excellent health to the eye. Rose K™ lenses can be custom fit by our Director of Contact Lens Services, Phyllis Rakow, to suit the varying levels of myopia and astigmatism in each eye.

DSAEK – An Alternative to Corneal Implants

Until now, when the cornea loses its transparency due to disease or injury there has only been one option: corneal transplant.

In order for the cornea to remain clear, it must remain relatively dry. Intricate bundles of collagen form a delicate layer of cells called endothelia. The endothelia acts as a pump to keep the corneal to accumulate water and develop corneal edema. In some patients, vision is impaired due to the disappearance of the nonregenerative cells of the endothelia.

Now, same day surgery can resupply the damaged endothelia with active endothelial pumping cells without replacing the entire cornea. DSAEK, Descemet’s Stripping and Automated Endothelial Keratoplasty, can be performed with a topical anesthetic and tiny incisions requiring no stitching. The DSAEK technique accelerates recovery time and greatly reduces the potential for complications.

Laser Corneal Transplantation

Corneal transplantation can now be done by laser. IntraLase Enabled Keratoplasty (IEK) is a new revolutionary way of performing full thickness corneal transplantation procedure.

The IntraLase laser procedure also reduces the need for stitches which in turn makes recovery both easier and faster.
