Comparing Vision Correction Options
Vision Correction Options: What is Right for Me?
When most patients begin to consider vision correction surgery, LASIK is the procedure that typically comes to mind. However, while LASIK is extremely effective at reducing visual refractive errors, this laser procedure is not always best for every patient. Fortunately, at The Eye Institute of Utah, we offer a full range of vision correction surgery options, including Visian ICLⓇ, LASIK, PRK, and Refractive Lens Exchange (RLE). We are happy to help you learn more about the vision correction options we offer, each of which has distinct benefits for our patients.
Visian ICL
The Visian ICL (Implantable Collamer Lens) is a highly appealing vision correction option, perfectly suited for a wide range of patients who are nearsighted or have astigmatism. In fact, this procedure is often ideal for patients who are not suitable candidates for LASIK and has a 99% patient satisfaction rate.1 Unlike LASIK which reshape a patient’s cornea, vision correction surgery with Visian ICL involves the implantation of an artificial lens implant that is 100% biocompatible and works in harmony with the natural eye. The Visian ICL procedure takes less than 20 minutes and results in near-immediate vision correction and a very short recovery time. The Visian ICL provides excellent night vision, has built-in UV protection, and is totally reversible if necessary. Visian ICL is often an ideal vision correction surgery for patients who are not good candidates for LASIK or PRK, including patients who:
- Have thin corneas
- Have dry eye
- Have a prescription out of range
LASIK
LASIK (Laser In-Situ Keratomileusis) is a form of laser vision correction surgery that permanently reshapes the patient’s cornea to reduce refractive errors. To begin the LASIK procedure, the surgeon uses a laser to create a flap in the patient’s cornea. Next, the cornea is minutely reshaped to smooth irregularities that prevent light from properly focusing and cause blurred vision. The entire procedure takes about 15 minutes per eye, and patients begin to notice improved vision within 24-48 hours of LASIK vision correction surgery.
PRK
PRK (photorefractive keratectomy) is very similar to LASIK in that this procedure reshapes the cornea to correct refractive errors. However, while LASIK surgery involves the creation of a corneal flap using a laser, no corneal flap is created during PRK. Instead, the top surface layer of the cornea (called the epithelium) is removed using a diluted chemical solution. Once the corneal surface is exposed during PRK, the surgeon then uses an excimer laser to reshape the cornea to correct vision. After PRK surgery, the surgeon will place a contact lens on the eye to act as a bandage while the epithelium heals. While PRK does typically entail a longer recovery period than LASIK, this procedure is often a better choice for patients who have chronic dry eye or thin corneas.
RLE (Refractive Lens Exchange)
Refractive Lens Exchange, or RLE, involves the permanent replacement of the natural lens of the eye in a procedure that is essentially identical to cataract surgery. To begin this 15-20 minute procedure, the eyes are numbed with anesthetic drops. A very small incision is made, and the lens of the eye is removed. The surgeon then replaces this with an intraocular lens implant (IOL) designed to improve the way the eye focuses light and corrects refractive errors. Most patients are able to return to normal activities within 2 days of RLE vision correction surgery.
