If you wear contacts and glasses, you understand first hand how cumbersome they can both be. After time, both contacts and glasses can have negative effects and actually slow your lifestyle down.
Many of our patients choose to actively take charge of their lifestyle by changing the way they see, literally.
The industry specializing in vision and eyesight has made incredible advances in the past several years, especially with respect to vision correction surgery, also known as refractive eye surgery or laser eye surgery. The types of vision correction these days is out of this world compared to twenty years ago, or even ten years ago.
Most of the surgeries today use technology to reshape the cornea. This is so that the light passing through the cornea will focus on the retina. There are other surgeries that focus on replacing the lens of the eye.
Keep reading to learn about the different types of corrective surgeries and how they work.
Lasik Corrective Eye Surgery
Lasik Corrective Eye Surgery reshapes the underlying tissue in order to focus the light into the eye in order to reach the retina. We recommend this procedure for those who are near or far sighted or have astigmatism. The uniqueness of Lasik revolves around the methodology of performance. We create a small flap on the outer layer of the cornea. In order to perform this surgery, surgeons must have pinpoint accuracy and advanced computer technology.
Photorefractive Keratectomy or PRK
Photorefractive Keratectomy or PRK uses a laser to reshape the cornea. This is unlike Lasik in that PRK only reshapes the cornea. PRK surgery is only ideal for those with mild near or farsightedness or astigmatism.
Lasek Eye Surgery
Lasek eye surgery is similar to PRK corrective eye surgery. In Lasek, the surgeon creates a small flap where the epithelial cells are loosened. This is done by using an alcohol solution. The surgeon then reshapes the cornea using a laser. Once the cornea is reshaped, the flap gets placed back down and set with a contact lens. This helps everything heal correctly. Lasek can treat nearsightedness, farsightedness and astigmatism.
Automated Lamellar Keratoplasty
Automated Lamellar Keratoplasty, or ALK, is recommended for those with extreme nearsightedness. For the most part, Lasik has replaced this method of surgery, with the exception of very few cases. For this procedure, the surgeon creates a flap in the cornea and makes an incision by hand to the sub-layer of the cornea.
Refractive Lens Exchange or RLE
The surgery corrects cataracts. For this procedure, the surgeon makes a small incision on the edge of the corna to remove the natural lens of the eye. The eye’s natural lens gets replaced with a plastic or silicone lens. The procedure is also used to correct severe near or farsightedness, as well as a host of other minor eye problems. You may also hear this called CLE, or clear lens extraction surgery.
EpiLasik Corrective Eye Surgery
This procedure is similar to photorefractive keratectomy, or PRK, in that, the surgeon separates a thin layer of the cornea to reshape it. This layer can be replaced, as previously mentioned, or removed all together. The procedure ends with a soft contact lens to protect the eye while it heals.
Prelex Corrective Eye Surgery
Presbyopic is a condition in which the eye’s lens loses its flexibility. Individuals with this condition may have difficulty focusing on close objects. The patient receives a multifocal lens to restore their focus, and over time, improve flexibility.
Intacs Corrective Eye Surgery
Intacs is short for intracorneal ring segments, which may also be referred to as ICR. Similarly to the previous procedures, the surgeon makes a small incision into the cornea. The surgeon then places two semi-circle shaped plastic rings around the cornea. This is to help flatten the cornea. For the most part, intacs corrective eye surgery has been replaced by laser surgeries.
Phakic Intraocular Lens Implants
Sometimes patients are too nearsighted or farsighted to be a candidate for Lasik. This is where the Phakic Intraocular Implants procedure comes in. In this procedure, the surgeon attaches an implant to the iris of the pupil. The eye’s natural lens is normally left.
Astigmatic Keratonomy Corrective Eye Surgery
This surgery corrects an astigmatism without using a laser. This surgery corrects the astigmatism by relaxing the cornea with two incisions around the edge of the cornea. This procedure can be combined with other laser eye surgeries.
