The cornea is the clear front part of the eye and is responsible for presenting an image of an object in space to the sensory retina. It can accomplish this because of its specific curvature which bends light as it passes through, which brings the image to pinpoint precision on the retina.
If the cornea is not shaped perfectly, light will not reach the retina in focus. If the corneal surface is curved too much (too steep), it will focus the image before the retina which will result in nearsightedness. If the corneal surface does not curve enough (too flat), it will focus the image after the retina which will result in farsightedness. It some cases, the cornea does not assume a spherical curve (it is bent), and the image does not come into a focus at all which results in astigmatism.
If we can take an imperfectly curved cornea and reshape it, it stands to reason that we can change where the image is focused. If we can do this in a controlled manner, we can get the image to focus on the retina, and improve clarity and quality of vision. That’s the process behind corneal reshaping, also called orthokeratology. It’s the same science and principle that gives refractive surgery the potential to change a patient’s uncorrected vision so drastically, but corneal reshaping is done non-surgically.
The process involves fitting a qualified candidate with a very specifically curved rigid gas permeable contact lens that they wear during sleeping hours. The lens design is different for each patient, dictated by the patient’s prescription and unique corneal topography (corneal shape). When fit correctly, the patient removes the customized contact lens upon awakening, and the cornea assumes the position enhanced by the shape of the contact lens that they wear each night. This new corneal shape results in improved uncorrected visual acuity, and in many cases eliminates the need for eyeglass correction or daytime contact lens wear. Corneal reshaping has made imperfect vision significantly and dramatically better for many of our patients. It has broadened career opportunities for athletes, pilots, and law enforcement, and enhanced the lives of 7-year-olds to grandmothers.
What used to take a year or more of exhaustive office visits and multiple lenses as the cornea was fine tuned over time, is now often done with one lens, like the Paragon CRT, that takes a patient from start to finish. Patients see dramatic improvements even on the first day after lens wear.
Patients presenting with degenerative corneal conditions like keratoconus require customized care. Using our in-office laboratory, visual acuity and comfort can be optimized for the Keratoconic patient.
Are there any alternatives for correcting vision besides refractive surgery? What if we could non-surgically change corneal shape in a controlled manner while the patient sleeps, resulting in excellent visual acuity during waking hours without the use of glasses or daytime contact lenses? We can!
Thank you for your 15 years of fabulous service to my family and me! I love seeing all of you…Pam, Dr. R, Dr. L., Fred, etc. etc. (wonderful staff). You’re like family. Thanks again for your kindness!- Paty G.
I have 4 children and have been a patient of Dr. Rembleski for 7 years. I am extremely happy and completely trust Dr. Rembleski with the care of our family’s vision. Dr. Rembleski is interactive and patient making the kids …- Kristen S.
Several years ago, I was having great difficulty with my vision and subsequently met Dr. Buffington. I was diagnosed with astigmatism which has since progressed to Keratoconus. From my first visit and every visit since, Dr. Buffington’s commitment to excellence …- Jeff H.
My family and I have been with this office for over 25 years. My right eye has a growth which makes wearing contacts very challenging. Drs. Rembleski and Buffington were able to create custom lenses in the smallest diameter possible …- Vicki P.
I have worn glasses for years, but as my vision got worse in graduate school, I found I was no longer able to play active sports–like basketball, softball, or even running–without corrected vision. Before I came to this office I …- Rich M.
I’d been wearing contact lenses for twenty years when I started coming to River City Doctors of Optometry. I had always worn soft lenses, so I was a bit apprehensive when Dr. Rembleski advised a switch to rigid gas permeable …- Amy M.
