Vision corrective surgeries, or refractive surgeries, such as LASIK, PRK, and LASEK, are revolutionary ways to lessen patients’ dependence on, and typically eliminate their need for, glasses and contact lenses. Each of these procedures uses an excimer laser to correct flaws in the shape of the cornea that cause myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.

Dr. Joseph P. Calderone, Jr. believes LASIK and other refractive surgeries should be done the right way for the right person with no exceptions. He will only recommend these elective procedures to improve vision if he believes they are truly right for you.

If you have considered a procedure which could eliminate your dependence on glasses and contact lenses, contact Dr. Calderone to find out if you are a candidate for LASIK or any of our other refractive surgeries.

LASIK

LASIK is the most popular type of vision corrective surgery. It is a painless procedure that takes less than an hour and is intended to reduce or eliminate the need for glasses and contact lenses. According the FDA in the original studies from the mid-1990s, seven out of ten LASIK patients achieve vision that is 20/20 or better, and the results are even better nowadays. LASIK has been performed over 3 million times in the past decade and has the highest patient satisfaction rating of any surgery.

Dr. Calderone is an expert in LASIK surgery and other refractive surgical procedures like PRK and LASEK. During your consultation with Dr. Calderone, he will determine which, if any, of these procedures are right for you to ensure that you receive the best possible results.

Myopia (nearsightedness), hyperopia (farsightedness), and astigmatism are refractive errors caused by flaws in the shape of the cornea. The cornea focuses images on the retina of the eye much like a camera lens focuses images on photographic film. An improperly shaped cornea focuses images on the retina like an out-of-focus camera, causing blurred vision. After creating and painlessly lifting a hinged, contact-lens-like flap of tissue from the top layer of the cornea, the LASIK procedure corrects for refractive errors using an excimer laser to precisely ablate, or vaporize, corneal tissue, reshaping it and improving its focusing capacity. The excimer laser ablates corneal tissue to as thin as 1/200th of a human hair. After the cornea is reshaped, the flap of tissue is folded back onto the cornea, where it reattaches within minutes without the use of stitches. A patient’s total time in our operating room is usually much less that an hour, and patients are usually able to return to normal activities the following day.

LASIK is regarded as a highly safe procedure. However, there are some risks that must be assessed before you undergo surgery. Dr. Calderone will explain your individual risk factors which may include visual halos around lights and dry eye. These symptoms may be a problem for some patients six to twelve months after surgery. For other patients who have thin corneas and/or high refractive errors (a need for strong glasses or contacts), LASIK could create the risk of visual instability after removing corneal tissue. For these patients, PRK and LASEK may be excellent alternatives as they leave more of the cornea intact.

PRK

PRK, or photorefractive keratoplasty or keratectomy, was the first excimer laser procedure introduced in the United States. The benefit of PRK is that it leaves more corneal tissue intact than LASIK. This is ideal for patients who have a greater refractive error, or the need for strong glasses or contact lenses, than is safely correctable with LASIK. PRK does not involve the creation of a thin flap of tissue from the outer layer of the eye, as is the case with LASIK. Instead, the excimer laser precisely ablates, or vaporizes, the corneal tissue at the surface or under the ultra-thin epithelial layer. A bandage contact lens is then placed on the cornea for a week after the procedure to aid healing. By leaving much less corneal thinning than LASIK, PRK is able to correct for strong refractive errors in patients that might otherwise not be candidates for refractive surgery.

If you are interested in PRK or other refractive surgeries, contact Dr. Calderone for a consultation.

LASEK

LASEK is the most recent innovation in refractive surgery and is something of a cross between LASIK and PRK. LASEK does not require the creation of a flap in the outer layer of the cornea as LASIK does, nor does it involve the ablation of tissue through the thinner epithelial layer as PRK does. Instead, there is an attempt to salvage the delicate epithelial layer by removing it completely and replacing it after surgery. After the epithelial layer is removed, an excimer laser is used to ablate and shape the cornea to precise specifications, much like PRK, before the layer is replaced. As a result, LASEK typically results in less discomfort and a shorter recovery time than PRK while still correcting for strong refractive errors and being suitable for patients with thin corneas that would otherwise not be treatable with LASIK.
