Other Cornea Procedures
The surface of the eye (also known as the cornea) may develop scar tissue, non-adherent cells or an irregular surface that can make the vision blurry, even with glasses, and at times may cause discomfort. When glasses, contact lenses and eye drops are not sufficient for vision or comfort, a surgical procedure may be helpful.
Phototherapeutic Keratectomy (PTK)
Phototherapeutic Keratectomy (PTK) is a common laser procedure performed to smooth the surface of the cornea. This surgery is less invasive than a corneal transplant and the recovery process is not as extensive. Unfortunately, not everyone qualifies for the PTK procedure. Your doctor will discuss which option makes the most sense for you depending on your individual situation.
Intacs is an FDA-approved procedure for patients with low levels of myopia, or nearsightedness, and very little astigmatism. Intacs corneal implants are also an option for individuals experiencing intolerance to contact lenses who are facing a corneal transplant. This treatment may be the best option to stabilize the cornea, improve vision, and potentially defer the need for a corneal transplant. The Intacs procedure may also be used as an alternative treatment for LASIK and other types of laser eye surgery.
This procedure is often performed to improve vision and reduce the distortion caused by keratoconus. The implants are placed within the cornea to reshape and flatten the eye so that light rays can more effectively focus on the retina, increasing vision. For those battling Keratoconus, Intacs have the ability to flatten the steep part of the cornea, reducing the “bulging” or cone area of the eye, often leading to less visual distortions.
Conductive Keratoplasty (CK)
Conductive Keratoplasty (CK) uses very accurate pulses of radio-frequency waves to reshape the cornea and may be used for a variety of corneal issues. Some people use CK electively to correct mild hyperopia as a way to reduce their dependence on reading glasses.
Astigmatic Keratotomy (AK)
Individuals best suited for Astigmatic Keratotomy (AK) have minimal or moderate degrees of astigmatism, no major history of eye problems, have had a stable eye prescription for at least a year, and want better vision without the need for contacts or eyeglasses. With the high levels of success in correcting astigmatism with LASIK eye surgery, Astigmatic Keratotomy is now commonly performed alongside other procedures, most often cataract surgery. You may also hear Astigmatic Keratotomy referred to as “Corneal Relaxing Incisions”.
Natural Lens Replacement
In some patients who have refractive errors outside the range treatable with LASIK, or for those who have some cataract formation, a Natural Lens Replacement procedure may be an ideal option. This treatment involves removing the natural lens of your eye and replacing it with an intraocular lens (IOL) to help reduce the need for glasses or contact lenses. A Natural Lens Replacement procedure is very similar to cataract surgery, which is done to remove the cloudy natural lens. When the natural lens is removed, it needs to be replaced with a new intraolcular lens (IOL), and there are a variety of lens options available to best suit your visual lifestyle goals.

Patients who would benefit from a Phakic Intraocular Lens Implant are those who have a strong glasses prescription, thin corneas or prefer a non-laser vision correction. The surgical technique is similar to that used in cataract surgery, however the natural lens is not removed, but an artificial implant is placed in front of it. The natural lens itself remains functional and intact.
