Descriptions Bladeless All-Laser LASIK: Dr. Cohen exclusively uses the Intralase femtosecond laser for all his LASIK procedures. We have eliminated use of the blade in the interest of safety and precision. Once the corneal flap is created to the exact depth and diameter that Dr. Cohen desires, the Excimer laser is used to resurface the eye to improve the vision. Implantable Contact Lens (Visian Lens): Dr. Cohen makes a small incision on the edge of the eye and inserts a permanent contact lens into the eye behind the iris. This procedure is currently approved for patients with severe myopia who are unable to undergo LASIK for full correction of their vision. Custom Bladeless LASIK : Vision is as individual as a fingerprint, and the Cohen Ophthalmology has the technology to measure your visual errors with computer-driven precision. During the laser vision correction procedure, the eye is resurfaced according to the computer’s recommendations rather than manual refraction. The goal is not only to eliminate the need for glasses but to protect the overall quality of vision. Photorefractive Keratectomy : Also known as “surface ablation”, PRK is a laser resurfacing of the eye similar to LASIK, but without the flap. This procedure may be a better option than LASIK for some patients, and it may be combined with a Custom Wavefront ablation. Phototherapeutic Keratectomy : PTK is a treatment for corneal scarring, recurrent corneal erosions and corneal dystrophies. It is similar to PRK but there is no refractive correction. CK (Conductive Keratoplasty) Radio Wave Treatment : In patients who see well at a distance but desire better near vision, we offer CK. This procedure utilizes radio frequency waves to reshape the peripheral cornea to induce reading ability. The procedure is typically done on the non-dominant eye, leaving the dominant eye for distance. With both eyes open you see both distance and near, reducing the need for reading glasses. Laser-assisted Intacs : Keratoconus is a corneal disease leading to vision loss. Historically, options for patients with keratoconus were limited to gas permeable (“hard”) contacts and corneal transplantation. We are proud to offer laser-assisted INTACS for these patients in an effort to stabilize the disease, improve the vision and enable patients to return to comfortable contact lens wear. For safety reasons, we use the femtosecond laser to create the channels with minute precision, required in eyes with thinning due to keratoconus, rather than the manual instrument. YAG Laser : This instrument is used to perform procedures in-office to treat secondary cataracts, narrow angle glaucoma and to prepare patients for Visian ICL implantation. Dry eye syndrome (DES) is a chronic lack of sufficient lubrication and moisture in the eye. It can range from mild constant irritation to severe ocular inflammation of the front surface of the eye. Reconstructive Eye Surgery : Dr. Cohen is at the forefront in the development of new eye reconstructive surgeries to restore vision in patients who have been previously diagnosed as blind. These patients come from many places to see Dr. Cohen. Artificial Cornea - Dr. Cohen is especially interested in using the Alphacor artificial cornea in complicated corneal transplations, such as in replacement of failed grafts. Since March of 2004, Dr. Cohen has been performing the artificial corneal implantation in Tucson. We see patients for evaluation of this procedure. Pterygium : A pterygium is a raised, wedge-shaped growth of the conjunctiva. Patients suffering from this problem often report irritation, redness, tearing, light sensitivity and dry eye syndrome. In early stages, artificial tears and supportive therapy is typically prescribed. Since a pterygium is most commonly caused by sun exposure, protecting the eyes from sun, dust and wind is recommended. Instilling artificial tears liberally is also helpful. In some cases, steroid drops are prescribed to reduce inflammation. Dr. Cohen specializes in the removal of these growths using grafts and occasionally AMT and fibrin glue– This reduces the reccurence rate. Amniotic Membrane Transplantation (AMT) : Researchers have discovered that a wound to a developing fetus repairs itself without a scar. Further investigation has revealed that the amniotic membrane, the thin membrane that surrounds the fetus in the womb, plays a key role in this “scar-less wound healing.” For many people, the presence or absence of scarring in the cornea means the difference between blindness and sight. Corneal specialists are now using amniotic membranes to cover damaged corneas, allowing the eye to repair itself with a reduced amount of scarring. AMT is used to help healing in patients undergoing stem cell transplants, corneal surgery and even pterygium removal. Endothelial Transplant (DSAEK): When the back surface of the corneal fails, the cornea swells and vision becomes cloudy. Historically, patients with corneal diseases such as Fuch’s Endothelial dystrophy can benefit from a transplant of only the back part of the cornea. Dr. Cohen has performed this revolutionary surgery for years. If you’re interested in learning more about our surgical procedures, call or email Cohen Ophthalmology today. |
