Parker Cornea and the ASCRS Meeting of 2017

Parker Cornea was well represented at the annual meeting of the American Society of Cataract and Refractive Surgeons (ASCRS) held May 5-9 in Los Angeles, CA.

The ASCRS meeting is the largest conference in the United States dedicated exclusively to the surgeon who specializes in anterior segment surgery. In other words, cornea, cataract and glaucoma surgery. Both doctors John and Jack Parker, as well as other members from the Parker Cornea team, attended the meeting to learn about new developments in their field. Besides innovative courses, ASCRS also gave the doctors the opportunity to view the all the new technology available for use in treatment of eye disease.

I have keratoconus? What do I do now?

Chances are you went to see your ophthalmologist or optometrist because you were not seeing as well as you used to see out of your glasses or contacts. But instead of simply getting a new prescription, you were diagnosed with a progressive, sight threatening condition. You probably left the office with questions such as- “What is keratoconus and what are my options?”

Keratoconus is a condition that causes the clear, normally sphere-shaped, front part of the eye to bulge forward into a cone-like protrusion. The front part of the eye, the cornea, thins as it protrudes and causes vision to blur.

Fortunately there are several  options to help preserve and/or maintain your vision.

Why Should I Have Cross-Linking Now?

I Can Still See Clearly with my Contact Lenses.

Keratoconus is a relatively common bilateral condition that is characterized by progressive corneal distortion. The disease causes the corneas to bulge into an irregular cone shape which permanently blurs vision. In early keratoconus, contact lenses or even glasses can effectively correct vision. Even hard contact lenses do not prevent keratoconus progression. In most cases, corneal cross-linking actually halts the progression of keratoconus.

Vision changes are often a specific, but not sensitive, indicator that keratoconus is progressing. Since only some corneal deformation can be corrected with hard contact lenses or even surgery, it is important to stop a cornea from deforming as soon as possible. A cornea that is too deformed is not able to see well even with a hard contact lens.

Parker Cornea is the first provider of FDA approved corneal cross-linking in the state of Alabama because we participated in Avedro’s FDA trials. We offer a full range of keratoconus interventions including Intacs and partial-thickness corneal transplants. We were the first surgeons in the United States to offer Bowman layer transplantation for keratoconus and we teach and speak internationally on the treatment of keratoconus.

Corneal cross-linking: What is it?

Corneal cross-linking is a reliable means of permanently stopping the progression of keratoconus. Keratoconus, a relatively common condition affecting 1/2000 people, typically begins shortly after puberty. By causing corneal thinning and bulging, keratoconus can lead to blindness even in young people. Keratoconus is not reversible and until recently the only treatment has been hard contact lenses–a treatment that improves vision, often with significant discomfort, but does nothing to slow the progression of the disease.

If you have been recently diagnosed with either keratoconus or post-LASIK ectasia it is important that you: 1) Never rub your eyes, and 2) Stop the worsening of your corneal warpage as soon as possible with corneal cross-linking.

Dr. Jack Parker Discusses Bowman Layer Transplantation at EuCornea

At the EuCornea meeting in Barcelona, Spain, on Sept. 9, Jack Parker, MD, talked about Bowman’s layer transplantation, a minimally interventional procedure to arrest progression of the disease in patients with advanced keratoconus otherwise ineligible for other procedures. Watch a video of the presentation below and learn more about Bowman layer transplantation at Parker Cornea here.
