The River’s Edge Optical prides itself in making sure our patients and customers know all the different vision correction options available to them besides traditional eyewear, ophthalmic lenses, and contact lenses. In addition to laser vision correction, an exciting therapeutic treatment for nearsightedness and astigmatism is called corneal refractive therapy (CRT). Corneal refractive therapy is also known as vision shaping treatment, overnight vision correction, corneal reshaping, and orthokeratology. These are all the same process, in which a retainer-like contact lens is worn overnight to gently reshape the cornea while you sleep. This alteration in curvature allows patients freedom from wearing glasses or contact lenses all day long and provides clear and precise vision with the reshaping process.
There are countless advantages to corneal refractive therapy, and ideal candidates are those that are adverse to having LASIK surgery, are concerned about the progressive vision loss from myopia (nearsightedness) in children, and children who are active in sports and leisure activities. It can also be a useful therapy for patients who have traditionally had difficulties wearing normal contact lenses.
The River’s Edge Optical is conveniently located next to Dunes Eye Consultants, a regional diagnostic vision medical clinic (Dunes Eye). Dr. Ferguson, the founder of Dunes Eye Consultants and The River’s Edge Optical, has been treating patients with corneal refractive therapy and corneal reshaping therapy for over a decade. He has hundreds of successful patients who have enjoyed this means of vision correction through both the ability to avoid dependency on daytime glasses and contact lenses and to reduce the progressive loss of vision from developing myopia.
Ideal CRT Candidates are Patients who:
– Do not want to wear contact lenses during the day
– Are children that are beginning to be nearsighted and are progressively losing vision
– Are too young for LASIK surgery
– Are active in sports and water activities
– Want a less expensive alternative to LASIK surgery
– Want a non-surgical and non-invasive alternative to LASIK surgery
Important Facts about Corneal Refractive Therapy and Corneal Reshaping
Corneal reshaping therapy only affects the cornea on the front part of the eye. The cornea shape is critical in maintaining sharp focus on objects by bending the light that enters the eye. Similar to what occurs in LASIK surgery where there is a permanent change to the curvature of the cornea, the corneal reshaping lens alters this curvature to provide clear, precise, and optimized vision with the modification. The corneal tissue is soft and can be subtly molded. The corneal refractive therapy lenses gently reshape the tissue and alter the curvature while you sleep.
When the lenses are removed in the morning, this slight change in curvature of the corneal surface results in clear vision during the day, reducing the need for contacts or glasses. Corneal refractive therapy contact lenses restore 20/20 vision in almost all cases in as little as one day up to a few weeks. Most cases of corneal refractive therapy respond quickly and immediately see the benefits after one night of use. What makes corneal refractive therapy so appealing is that it is a safe, non-surgical, non-invasive vision correction method, and it is totally reversible. Stopping the reshaping process, the eye will return to its natural shape normally, gently, and accurately. One of the important variables in corneal refractive therapy is your chemistry, and Dr. Ferguson pays special attention to ensure that any subtle, subclinical dryness is managed appropriately to create maximum effect, comfort, and vision performance.
Controlling Progressive Loss of Vision from Myopia (Nearsightedness)
Otherwise known as nearsightedness or shortsightedness, myopia is a condition in which your near vision is clear, but distant objects appear blurred to an uncorrected eye. Typically, this is caused by the eye changing shape through growth and elongating or an increase in curvature on the front surface of the eye. This normally occurs in early adolescence through later teen life, and even into early adulthood. The resulting effect is a mismatch between the length and curvature of the eye and where the rays of light are to be focused on the retina for precise vision. This imbalance of optical lengths and power results in the image focusing in front of the retina, creating blur and defocus. By using corneal refractive therapy lenses, a gentle reshaping process of the cornea occurs, and the cornea can optically realign with the focal point of the retina. It allows patients with as high of corrections as -10 to enjoy clear and distinct vision without typical contact lenses or glasses.
The FDA has not yet labeled corneal refractive therapy lenses for myopia progression control, but there are countless studies now supporting this evidence. It is being prescribed worldwide for this use. Dr. Ferguson has had firsthand experience in monitoring patients that have worn the lenses for over a decade. He reviews where their baseline nearsightedness began and where it ended once they stopped treatment, allowing their eyes to trickle back to normal shape before having LASIK surgery. In almost all cases, retardation of the progression of myopia was highly significant with minimal change occurring in the vast majority of patients, supporting the clinical studies.

If you are active and not interested in LASIK surgery but would like to reduce dependency on daytime glasses or contacts, corneal refractive therapy can be a wonderful option for you. If you have a child who has nearsightedness that is progressing and you are concerned about protecting their current state of nearsightedness, then corneal refractive therapy is the answer.
