Four Types of Refractive Procedures for Laser Vision Correction
Vision correction surgery is a common procedure used to correct various vision problems in San Antonio, TX. These eye refraction procedures help correct refractive errors. The goal of refractive procedures is to either reduce or end the need for glasses or contacts. At Focal Point Vision, our doctors can evaluate your eye health to determine if you would benefit from a laser vision correction surgery.
What are refractive errors?
Your vision depends on how well both your cornea and lens focus light on the retina. The light must refract to focus on the retina properly. Refractive errors are vision problems that are caused by an irregularly-shaped cornea. These errors occur when light from an object cannot focus on the retina properly, causing blurry vision. There are four types of refractive errors that we treat at Focal Point Vision, including:
Nearsightedness: Myopia occurs when objects in the distance are blurry. This occurs when the eye is longer than normal, or the cornea has too much curvature.
Farsightedness: Hyperopia occurs when you can see objects in the distance clearly, but things up close are blurry. This happens because the eye is shorter than normal, or if your cornea is too flat.
Astigmatism: This occurs when items are blurry at a distance and can be caused by an irregularly-shaped cornea or lens.
Presbyopia: This is an aging eye that has lost its ability to focus. Refractive surgery cannot be used to correct this.
Refractive surgery options
At Focal Point Vision, our doctors in San Antonio, TX offer a variety of laser vision correction surgeries, including:
Refractive lens exchange: This procedure is similar to cataract surgery in that the natural lens is replaced with an intraocular lens to improve vision. This is a great choice for those with myopia or hyperopia who aren’t eligible for LASIK eye surgery. A small incision is made in the cornea, which is split up and removed. A new custom lens is implanted in its place.
LASIK: Laser-assisted in situ keratomileusis is our most popular refractive eye surgery in San Antonio, TX. It can be used to correct hyperopia, myopia, and astigmatism by changing the cornea’s curvature. The eyes are fully numbed before a thin corneal flap is folded back to alter the curve of the cornea. This helps improve vision in one day.
PRK: PRK eye surgery is the first that grants patients 20/20 eyesight. It can fix or improve myopia or hyperopia and has a slightly longer healing process than the other two surgeries. It is used on patients who don’t have enough cornea tissue to be eligible for LASIK surgery. The procedure is just like LASIK, except a flap isn’t needed. The thinnest outermost layer of the eye is removed, and the cornea underneath is reshaped.
Implantable contact lens: Implantable contact lenses correct many visual acuity problems for patients who aren’t candidates for PRK or LASIK. They offer sharp and clear vision without the need for contacts or glasses. These implants are made of biocompatible materials that are well tolerated by the eye. Those with astigmatism or myopia with a consistent eyeglass prescription and in good health are the best candidates for this procedure. A tiny opening is made into the eye to place the new lens.
