- PRK vs LASEKIf you do any research these days into your refractive surgery options, you will inevitably see the terms “LASEK”, “PRK” and occasionally “advanced surface ablation” (ASA) being batted around. What is PRK, what’s LASEK, what is the difference, and how does ASA relate to these? First, very simply, the above procedures reshape the cornea to reduce or eliminate your need for glasses and contacts just like LASIK and Intralase do, but they do so without creating a flap. With PRK and LASEK, the re-shaping of your cornea takes place just under the thin loose surface layer of your cornea, called the epithelium. In both procedures, a contact lens is placed on the eye to protect the new cells as the heal. A lot of the information available to you on the internet regarding LASEK in particular is misleading and at the very least confusing, so I think it’s important that […]
- ICL (Implantable Contact Lenses)I was speaking to a fellow surgeon today on whom I performed bilateral ICL surgery last week. We’re used to our ICL patients being overwhelmed and delighted with their vision but she went even further than this. She remarked that the improved contrast, detail, and magnification she has gained with the ICL has made her a more confident surgeon! As a dermatologic surgeon, she is able to see the details and irregularities of the skin far better than ever before. You may be wondering- why and how a lens implanted in the eye can provide gains in visual acuity and vision quality? By taking the lens power from in front of the eye, as is the case with glasses and conventional contact lenses, and placing that lens power closer to the nodal point of the eye, we can realize several unique visual benefits for the nearsighted person. Among these are […]
- Contact LensesWe ophthalmologists, and especially refractive surgeons, don't have to go too many days in our clinics without seeing the damage that long term contact lens use can do to the eye. Far too frequently, patients will present with issues related to contact lens use, misuse, and overuse. These problems include but are certainly not limited to contact lens ...
