LASIK & PRK
LASIK eye surgery is a common procedure that corrects certain vision problems such as myopia (nearsightedness), hyperopia (farsightedness) and astigmatism. It is intended to eliminate the need for eyeglasses or contact lenses. LASIK eye surgery is the most common type of refractive surgery. Refractive surgery changes the shape of your cornea to correct your vision. This procedure can be quite effective, and has very few side effects.
LASIK is a great option for many individuals considering laser vision correction for a variety of very personal and professional reasons. The lifestyle benefits can be tremendous for active and social people. These benefits can enable people to more freely pursue their hobbies, sports activities or career options.
There is perhaps nothing more important in the LASIK eye surgery process than determining your candidacy. Your candidacy begins with a thorough eye health evaluation to check the overall health of your eye as well as the corneal thickness and shape.
During your initial screening, we will examine your eyes and perform comprehensive testing to make sure that LASIK eye surgery is the right procedure for you. A medical and eye history will be taken and several tests will be performed, including dry eye testing, visual acuity, refractive error, screening visual field, pupil size, eye pressure, general eye health and a detailed corneal evaluation (thickness and shape). Dr. Ginsberg is not only an experienced LASIK and refractive surgeon but also a fellowship-trained cornea specialist. This specialty makes him the best type of ophthalmologist to determine who is the right candidate for LASIK and who is not. If you are not an appropriate LASIK candidate and still desire freedom from spectacles and contact lenses, he will guide you as to which of the alternative procedures can help you to achieve your visual goals.
The LASIK Procedure
During LASIK surgery, we will numb your eyes using a local anesthetic. Then, we will create a thin, hinged flap on the surface of the cornea. This flap is then gently moved back to expose the inner layers of the cornea. The next step is to reshape the eye using an excimer laser. This will improve the way that light refracts onto the retina, allowing for clear vision. Once the eye is properly reshaped, the flap will be smoothed back over. There are no stitches required after LASIK, and the recovery time is quite fast!
PRK or ASA
PRK (Photorefractive Keratectomy) or ASA (Advanced Surface Ablation) is a laser eye surgery that corrects common refractive errors like myopia, hyperopia, and astigmatism. This procedure is meant to reduce or eliminate dependency on glasses and contact lenses.
This procedure is best suited for those who are not good candidates for LASIK surgery. The procedures are very similar, except that during PRK there is no corneal flap created. This is typically better for people whose corneas cannot withstand a corneal flap.
To begin the surgery, we will numb your eye using a local anesthetic. Next, we will remove the first layer of the cornea ( the epithelium) using a buffing tool and an alcohol solution. The next steps are the same steps used during LASIK. The Excimer Laser will reshape the eye. Once reshaped, we will place a contact-lens bandage over your eye to keep it safe and promote healing. Healing after PRK takes longer than after LASIK, but the results are comparable.
