Eye Drops And Ultraviolet Light — U.S. Clinical Trial Has Potential To Dramatically Change Landscape For Patients With Keratoconus And Corneal Ectasia

San Leandro, California Ophthalmologist One of Few Doctors Offering Treatment in Clinical Trials  

An exciting new treatment option for patients suffering from Keratoconus and Corneal Ectasia is in U.S. Clinical trials right now.  Corneal Cross-linking is a non-invasive treatment that has the potential to halt the progression of Keratoconus and Corneal Ectasia, possibly saving patients from the need for corneal transplant.

Keratoconus and Corneal Ectasia

Keratoconus and Corneal Ectasia cause the cornea (the clear front part of the eye) to thin and become weak, to bulge and protrude outward thereby causing visual problems. Keratoconus occurs naturally, while Corneal Ectasia can occur when the cornea is weakened by LASIK or PRK procedures. Both conditions can severely compromise eyesight and may lead to legal blindness and corneal transplant surgery.

Corneal Cross-linking

The Corneal Cross-linking treatment being investigated in the clinical study is Avedro’s VibeX eye drops (Riboflavin) and KXL device (Ultraviolet light). Corneal Cross-linking may help improve vision by stabilizing the cornea and reducing astigmatism.  Traditional treatments include Rigid Gas Permeable contact lenses, corneal implants, or corneal transplant.

The study was initiated to investigate an alternative way to treat Keratoconus and Corneal Ectasia in patients after LASIK and PRK.  Only a small percentage of patients who have the surgery develop the sight-threatening condition, however, it frequently leads to corneal transplant or loss of vision.

Nicholas Batra, M.D.

Dr. Nicholas Batra, Medical Director of Batra Vision Medical Group in San Leandro, California, is one of only a handful of clinical investigators nationwide enrolling patients in this study.

“As a cornea specialist, I see this therapy has the potential to dramatically change the landscape of treatment for patients with Keratoconus and Corneal Ectasia. The United States is the only western industrialized nation where Corneal Cross-linking is not approved for use outside of clinical trials.”

Corneal Cross-Linking therapy is offered to patients in Mexico, Canada and Europe and other countries around the world. Dr. Batra is currently accepting US patients for the post-LASIK and Keratoconus segment of the Cross-Linking study.

Dr. Batra was awarded his Doctorate of Medicine at the University of California, Los Angeles (UCLA), and completed his ophthalmology residency at the University of California, San Francisco. In addition, Dr. Batra received a fellowship from UCSF/Proctor Foundation in Cornea and Refractive surgery and a Fellowship with the prestigious Heed Foundation.

Senior Citizen Laser Eye Surgery by Dr. Frank Thomnpson

Presbyopia is one of the most common conditions affecting senior citizens nowadays. Presbyopia is caused by the eye’s inability to focus in old age, especially with near objects. Thus, blurring of vision occurs, more prominently in the dark. Presbyopia typically presents with blurring of vision when looking at near objects, requiring patients to hold objects far away to be able to see or read. Some people who are nearsighted before they are 40 years old find that their nearsightedness is actually surprisingly advantageous, allowing them to see more clearly when presbyopia starts to set in.

Previously, presbyopia was treated with corrective lenses that are able to compensate for the loss of the eye’s ability to focus effectively. If the patient has an additional refractive error, convex lenses can be used. If corrective lenses aren’t enough, senior citizens can be given a prescription for bifocals or multifocals. The downside to the use of these lenses is that they can occasionally distort the images that you see. Also, the prescription of the glasses changes constantly, as presbyopia progresses.

Senior citizens who would rather not use eyeglasses or contact lenses can opt to undergo laser eye surgery in order to correct presbyopia. Typically, LASIK eye surgery is used in correcting presbyopia. Conventional LASIK eye surgery, however, can further aggravate the senior citizen’s inability to see things up close. Thus, instead of employing the typical LASIK eye surgery, a specific approach, known as monovision, is used.

The monovision approach was initially employed using contact lenses. One contact lens corrects near vision in one eye while the other contact lens corrects distance vision in the other. In time, a more permanent form of monovision was developed. Instead of using contact lenses, laser can be used to permanently change the vision of the eye. One eye can be permanently corrected for near vision while the other eye is permanently corrected for distance vision.

Some people find it very hard to adjust to monovision. Before undergoing monovision laser eye surgery, it is a good idea to first try with contact lenses. This will help you determine whether you can handle permanent monovision or not. If you can’t, laser eye surgery may not be for you. You may want to consider other forms of treatment for presbyopia. These treatments include the use of intraocular lenses and novel techniques, such as the use of scleral expansion bands and the surgical reversal of presbyopia, or SRP.
