There are many successful advanced vision correction procedures. Most of them are designed to help the people who wear glasses or contact lenses to dramatically reduce or even completely eliminate their dependence on these corrective tools. Vision correction procedures can benefit patients with nearsightedness, farsightedness, astigmatism and presbyopia. Astigmatism manifests as distorted or warped vision when the surface of the eye is irregular in shape. Presbyopia is a condition in which eye progressively loses the ability to focus on near objects with age. Here is a quick review of some of the most popular advanced vision correction procedures. LASIK
LASIK is a short for laser-assisted in situ keratomileusis. This is a type of eye surgery that is performed using a laser. LASIK method has some very important advantages over the other types of vision correction procedures. For example, it is relatively painless and provides very fast recovery. During the procedure, eye surgeon will perform a flap on corneal tissue, remodel the cornea underneath the flap using the laser, and reposition the flap.
Advanced Surface Ablation
This procedure is also known under the name Wavefront-guided surface ablation. This is a procedure that is similar to LASIK but with one important difference – surface ablation technique doesn’t cut a flap. Surface ablation is any technique that applies the laser immediately underneath the epithelium. The surface skin cells of the epithelium are softened with diluted alcohol solution and then removed before using the laser. This technique is much safer than LASIK and may be an ideal alternative for some patients, since it removes all risks of flap complications.
Blended Vision treatment is designed to greatly reduce or even completely eliminate the need for reading glasses. This option is better than the classic LASIK surgery, which is powerless against the effects of ageing on the vision. From the early middle age, the lenses inside the eye are starting to lose their ability to change shape and focus objects from distance to near and back. Laser Blended Vision fights this obstacle by adjusting each eye in different ways. The brain will compensate for the difference combining two images (from left and from right eye) into single image of much greater depth and vision.
CustomCornea is a customized laser eye surgery that reshapes the cornea to meet patient’s individual needs. This procedure treats vision problems that may not be detected using a traditional exam and delivers improved vision and reduced glare. Before the procedure, it will be necessary to capture a picture of the eye using a custom wavefront technology. This map of an eye is transferred to laser system to provide a guide for the laser.
