Our Alternatives To LASIK in Las Vegas, NV
Millions of people suffer from poor vision and wear glasses or contact lenses to correct the issue. While helpful, these can be inconvenient and annoying. While many have found a solution in LASIK eye surgery, others are unable to have it due to the nature of their eye problems. Siems LASIK & Eye Centers’ alternatives to LASIK in Las Vegas, NV, such as implantable contacts, are an exciting new option for those ineligible for corrective laser eye surgeries. Implantable lenses offer the same results as other eye surgeries, including better vision, convenience, and improved quality of life.
Anyone suffering from nearsightedness, astigmatism, or myopia can be treated with implantable contact lenses, and the surgery is quick and easy. Patients are usually done in 30 minutes or less. There are 3 different types of implantable contacts, including lenses that are placed behind the iris, lenses that attach to the iris, and bifocal lenses. Our own Dr. Jon Siems has been providing eye surgeries since 2001. He is a well-reputed doctor and can correct your vision today. Hear him talk about implantable contact lenses.
Photorefractive keratectomy, or PRK, is a laser procedure that reshapes the cornea to correct mild to moderate myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. It is the second most common laser eye surgery after LASIK. While during LASIK, a flap is created to access the cornea, during PRK, the entire epithelial layer of the cornea is removed and later allowed to grow back. Either way, the cornea is reshaped for better vision.
PRK Advantages for Patients
Compared to LASIK, PRK provides our surgeon with greater control over the location and amount of tissue being removed, which permits more precise results. PRK gently sculpts rather than cuts, maintaining corneal strength while providing impressive vision correction. Other advantages are:
• Less Depth of Laser Treatment
• No Corneal Flap Complications
• Ability to Be Performed on Thin Corneas
The procedure offers distinct benefits to individuals whose activities put them at elevated risk of eye injury—such as athletes—and for patients whose corneas are too thin or whose pupils are too large to permit LASIK. PRK also avoids not only the complications from corneal flaps but also a serious complication known as corneal ectasia, which can result in distorted vision and even permanent vision loss.
The Disadvantages of PRK
Both LASIK and PRK have comparable rates of vision improvement and carry some of the same risks, so a serious consultation with the ophthalmologist is necessary to determine which surgery will be most beneficial. While PRK may be a preferable to LASIK surgery for some, it is not without drawbacks:
- More discomfort for the first few days after surgery
- Longer recovery period
- Greater risk of postsurgical eye infection
- Greater risk of temporary or permanent haziness of the cornea
How the Procedure Works
Before we get started, we numb the eyes with anesthetic eye drops. Our surgeon then uses an excimer laser, with targeted laser energy, to reshape the cornea. He has complete control over the laser throughout the procedure for a highly precise and customized result, designed to provide the best vision possible. The entire procedure takes only a few minutes. Because of the potential for temporarily blurred vision, the surgery is often performed on only one eye at a time. We’ll schedule the second eye when the vision in the first has adequately cleared.
After the procedure, the eyes are bandaged with a soft contact lens to protect the cornea. New cells grow back over the next few days to replace those that were removed. Our surgeon removes the contact lens in a follow-up exam.
After PRK, patients rest before returning home. They may be required to wear eyeglasses until their vision has stabilized. Our surgeon prescribes eye drops to prevent infection and keep the eyes moistened.
While vision may improve immediately, full results can take several days or even weeks to become apparent. Strenuous exercise should be avoided for at least a week because this can interfere with the healing process. Patients can often see well enough to drive after 2-3 weeks.
The results of PRK are considered comparable to those of LASIK. Some may experience only 20/40 vision and still need glasses or contact lenses. PRK does not correct presbyopia, a natural change in the eyes that affects people over 40. Patients who require reading glasses will continue to need them. Overall, patients must maintain realistic expectations of the results of any laser surgery to achieve satisfaction.
Risks of PRK
As with any type of surgery, there are certain risks associated. Many of the complications that may arise are similar to those that can occur after any type of refractive surgery. They include:
- Postsurgical Infection
- Adverse Reaction to Anesthesia
- Inaccurate Vision Correction
- Sensitivity to Light
- Problems with Night Vision, such as Halos
- Hazy Vision
- Dry eyes
