Cornea Center

The cornea is a clear, dome-shaped surface that covers the front of the eye. The main function of the cornea is to allow light to pass into the eye so that it can reach the lens and the retina in the back of the eye. This is why it is important for the cornea to be transparent. The second function of the cornea is to focus light, similar to a camera lens. The cornea accounts for two-thirds of the eye’s total optical power. Cornea health is extremely important to your vision and is dependent on certain factors such as health of the conjunctiva and the eyelids. The conjunctiva is tissue that covers the front of the eyeball except the cornea and is also lined in the back of the eyelids. Both contain glands producing tear fluid, an essential part of cornea health. Cornea diseases can cause distorted vision or even loss of vision.

Common corneal conditions, eye cornea diseases

Common corneal diseases and disorders

  • Corneal Abrasions – caused by trauma resulting in the loss of the surface epithelial layer of the cornea
  • Corneal Dystrophy – a build up of cloudy material causing one or more parts of the cornea to lose clarity
  • Fuchs’ Dystrophy – cloudy morning vision
  • Keratitis – inflammation of the cornea
  • Keratoconus – degenerative disease where the cornea thins and becomes cone-shaped.

What our Patients Say

‍A few years ago, I decided to have laser eye surgery to correct my lifelong problem with nearsightedness.  Before that I always wore glasses or contacts.  I remember having frequent problems with contacts which would lead to problems with sunglasses or diving masks and the like.  when I chose to have eye surgery, I decided to go with Dr. Narvaez.  As a surgeon myself, I knew of his reputation and we had some patients in common and I was always impressed by his work.  Therefore, the choice was clear to me even though I knew many other Doctors who could do the procedure. After the procedure, I had excellent vision.  I love my new vision and enjoy being glasses and contacts free.  Dr. Narvaez is an excellent surgeon and I highly recommend him.

What our Patients Say

I endorse my ophthalmologist, Julio Narvaez, MD.I have known him since moving to Loma Linda University in 2010.I was referred to him by a trusted friend and Ophthalmologist and was his patient; he is caring, bright and understood the problem and how I needed to be treated. He explained my options and allowed me to feel I had chosen my treatment while gently steering me the right direction. He was flexible when I asked to have my choice of anesthesia, which was local without sedation. He was not bothered by my continuous alertness during the surgery.

He is a bright and flexible surgeon, who makes excellent personal decisions and keeps perspective in his work and life.I would happily return to him for more care when needed.I endorse him without reservation and am glad to consider him a friend and colleague. Sincerely,

Dean A Hadley, MD Loma Linda University

What our Patients Say

It’s amazing to have new technology nowadays. Previously, I had worn eyeglasses for over 35 years. After having Symfony lenses implanted into both eyes, it’s a wonderful feeling to be able to read almost everything without glasses. All the worries and fears prior to the surgery were for nothing. It’s awesome; my vision is clearer and better!  I’m so grateful to have a very good, knowledgeable, and hardworking team. My experiences with you will forever be in my heart. God is so good. He will always guide me all the way.
