Refractive and laser eye surgery, known also as vision correction surgery, is implied to surgical procedures that repair problems with vision. In the last decade there have been huge developments in the process of vision correction using lasers. Both refractive and laser eye surgery allow patients to see better than they previously.
Many laser eye vision correction surgeries are done by reshaping the eyes cornea. The cornea is the front part of the eye that lets light pass through it and focus it on the retina, which is the back of the eye. Other surgical procedures are done by replacing the natural lens of the eye.
LASIK, otherwise known as laser in-situ keratomileusis, is a surgery that assists in nearsightedness, farsightedness, and astigmatisms. The surgeon will reshape the tissues found underneath the cornea, so the light can focus properly. A flap is made in the outer layer of the cornea in order to access the tissues that lay underneath. This flap is what differentiates LASIK from other surgical vision procedures. During LASIK surgeons may also use wavefront technology. This technology creates a detailed picture of the cornea to use as a guide during surgery.
During Epi-LASIK, a surgeon separates the thin layers of tissue from the cornea and then reshape them using a laser. The area is protected by using a soft contact lens to hold the flap in place while the tissues are healing.
PRK, otherwise known as photorefractive keratectomy, is a surgery that assists in the correction of mild to moderate nearsightedness, farsightedness, and astigmatisms. Similar to LASIK a laser is used in PRK to reshape the cornea. In PRK the laser is only used on the cornea and not the tissues underneath. Similar to LASIK, wavefront technology is used in PRK to obtain a picture of the cornea.
LASEK, otherwise known as laser epithelial keratomileusis, is a surgery that is very similar to PRK that assists in nearsightedness, farsightedness, and astigmatisms. Surgeons create a flap and use an alcohol solution that loosens the tissue and the laser is then used to reshape the cornea. Once this part of the procedure is complete the surgeon will put a soft contact in place to hold the flap while it heals.
During Epi-LASEK, a surgeon cuts a small flap within the cornea while using an alcohol solution to separate the thin layer of tissue for the cornea, reshapes it with the laser, and is protected by a soft contact lens holding the flap in place for healing.
RLE, refractive lens exchange is known by a few different common names including PRELEX, CLE, and RLR. This is the same surgery that is done for cataracts. Surgeons make a small cut at the edge of the cornea. They then remove the eyes natural lens and replace it with a plastic or silicone lens. This surgery is used to correct severe farsightedness and nearsightedness. The surgery works for patients with dry eye, thin corneas, and minor issues with their corneas.
Surgical laser vision correction is safe and effective. Similar to any surgery there are known side effects that can include: infection, a delay in healing, under or over correction, worse vision, corneal haze, halo effect, regression, and/or flap damage. All of which are rare but can occur. It is important to always talk in depth with your laser vision correction surgeon before the procedure about any questions or concerns you may have.
