Dr. Howard N. Greene performs LASIK surgery and PRK surgery in North and South Carolina. He has helped patients achieve freedom from glasses and contacts using lasers to reshape the cornea and allow light to focus properly on the back of the eye.
Just a few minutes in our LASIK suite can result in years of visual freedom from glasses and contacts to enjoy life-changing things such as:
Some LASIK centers only offer general purpose, non-tailored, one-procedure-fits-all LASIK. Not at Carolinas Centers for Sight, P.C. Every LASIK patient receives custom, blade-free LASIK to address their unique vision characteristics. The result is better end result vision.
If your cornea is not shaped in a way that allows light to properly focus on the retina (called a refractive error), you will have blurry vision. LASIK, or the LASIK alternative called PRK, can be performed to correct the corneal shape, allowing light to properly focus and ultimately providing clear vision.
Both LASIK and PRK procedures use excimer lasers to reshape the corneal tissue. These are “cool” lasers that generate ultraviolet range power to remove microscopic layers of tissue – approximately 1/10 the width of a human hair. The laser is programmed to remove precisely the amount of tissue needed to achieve the desired visual result for your unique refractive error: nearsightedness, farsightedness or astigmatism.
At Carolinas Centers for Sight, P.C. in Florence the Wavefront Optimized Allegretto Wave® Eye-Q laser is used for LASIK and PRK. Precise laser energy pulses are applied on the periphery of the cornea in order to maintain the cornea’s natural shape while also respecting the cornea’s thickness and curvature. This can reduce the risk of halos, glare and nighttime visual disturbances after treatment. Best of all, the vision results using this technology are superb for most patients.
To be a good candidate for our LASIK technology, you must have the correct corneal thickness and eye health to support the procedure. That’s exactly why we have every LASIK patient undergo an extensive LASIK Consultation, to ensure a highly effective and accurate procedure.
Nearsighted individuals typically have problems seeing well at a distance and are forced to wear glasses or contact lenses. The nearsighted eye is usually longer than a normal eye and its cornea may also be steeper. Therefore, when light passes through the cornea and lens, it is focused in front of the retina. This will make distant images appear blurred. LASIK and PRK are both solutions for Myopia.
Farsighted individuals typically develop problems reading up close before the age of 40. The farsighted eye is usually slightly shorter than a normal eye and may have a flatter cornea. Thus, the light of distant objects focuses behind the retina unless the natural lens can compensate fully. Near objects require even greater focusing power to be seen clearly and therefore blur more easily. LASIK or PRK monovision, refractive lens exchange (RLE) and cataract surgery with the insertion of a multifocal lens are all solutions for Hyperopia.
Asymmetric steepening of the cornea causes light to be focused unevenly, the main optical problem in astigmatism. To individuals with uncorrected astigmatism, images may look blurry or shadowed. Astigmatism can accompany any form of refractive error and is very common. Solutions for astigmatism are LASIK, PRK, corneal relaxing incisions and Toric lens implants.
Presbyopia is a condition that typically becomes noticeable for most people around age 40 to 45. In children and young adults, the lens inside the eye can easily focus on distant and near objects. With age, the lens loses its ability to change focus adequately.
The lens inside the eye and its supporting structures lose the ability to make the lens longer during close vision effort. To compensate, affected individuals usually find that holding reading material further away makes the image clearer. Ultimately, aids such as reading glasses or bifocals are typically needed by the mid-40s. Surgical solutions for presbyopia include monovision LASIK or PRK, cataract or refractive lens exchange with a multi-focal IOL implant.
Not a LASIK candidate? Explore the EVO ICL. It is a soft lens, like a contact lens, that is surgically placed into the eye. The lens works similarly to LASIK and PRK in that it permanently corrects your vision. Unlike these procedures, however, it doesn’t require cutting or reshaping of the corneal tissue and it is removable.
Good candidates for this procedure are people ages 21 to 45 who are nearsighted and have had stable vision for a year. The ICL is made to help correct patients with low myopia (‑3 diopters) to high myopia (‑20 diopters). It can be a preferred option for people with severe dry eyes or thin corneas.
FDA-approved, ICLs have been available for 10 years. To date, more than 500,000 ICLs have been implanted in patients worldwide, with excellent visual outcomes. The patient satisfaction rate to date is 99%.1
