Laser Eye Surgery for Different Eye-Problems

A medical procedure to correct refractive error is known as eye-surgery. There are different types of eye-surgeries for different refractive-errors and eye-problems, diseases. Eye-surgery procedures based on laser technique are eye-laser-procedures that actually involve the use of laser to reshape the surface of the eye. As there are types of laser-eye-surgery for different eye-problems but all the procedures involve correcting problems reshaping cornea. Laser surgery for eye is done to improve or correct myopia (short-sightedness), hypermetropia (long-sightedness) and astigmatism (uneven curvature of the eye’s surface).

Lets’ understand what laser surgery involves. It involves reshaping cornea which is the transparent tissue that covers the front of the eye. This tissue helps to control focusing. In procedure, a computer-controlled excimer laser is used to remove microscopic amounts of tissue from the cornea. It is done to restore normal eyesight. The thin outer layer of the cornea is removed and the underlying layers are reshaped. In simpler words, a thin flap of corneal tissue is created. This flap is then lifted out of the way. And using laser technique reshapes the underlying tissue and the flap is replaced to cover the newly re-contoured surface. Benefits of laser surgery are:

•    It corrects different refractive-errors.

•    It corrects different eye-diseases and problems.

•    It eliminates need of wearing contact lenses and eye-glasses.

•    It is associated with minimal discomfort.

•    It does not require any surgical-equipments.

•    It does not require any stitches.

•    It does not require any bandages after surgery.

•    Results are dramatically seen as a improved and correct vision.

Some after-precautions are:
•    Do not rub eyes.

•    Do not use soaps or shampoos. Make sure eyes are completely safe from such chemicals.

•    Keep eyes safe from pollution and dust & dirt.

•    Avoid driving. Only resume driving vehicles on your own, after consulting and getting permission from your eye-doctor.

Above are few precautions a person gone under eye laser surgery must follow. However, eye-doctor will conduct a proper consultation session with patient to inform and educate about surgery, after and before preparations & precautions, what to expect during surgery, side-effects and results etc. Make sure you consult with expert eye-surgeon. There are online websites from people can gather detailed information about eye-care-clinics and expert-eye-surgeons.

Types of Laser Eye Surgery Procedures

Laser Eye Surgery is also known as Vision Correction Surgery and Refractive Eye Surgery. This is a surgical procedure performed by expert eye-surgeon to correct vision problems. There are types of laser eye surgeries and most of them work by reshaping the cornea so that light traveling through it is properly focused onto the retina located in the back of the eye. The other types of such procedures involve replacing the eye’s natural lens. Following are some of the common, important and frequently done surgeries by experts for patients.

•    LASIK: The most common type of laser surgery. It stands for laser in-situ keratomileusis. It is performed to correct vision in people who are nearsighted, farsighted, and have astigmatism. A flap is made in the outer layer of the cornea so that the underlying tissue can be accessed. Then surgery involves correcting vision by reshaping underlying corneal tissue. This is done so that it can properly focus light into the eye and onto the retina.

•    PRK: It stands for photorefractive keratectomy. This type of laser eye surgery is used to correct mild to moderate nearsightedness, farsightedness, and/or astigmatism. In this procedure, an eye surgeon uses a laser to reshape the cornea. This laser, which delivers a cool pulsing beam of ultraviolet light, is used on the surface of the cornea.

•    LASEK: It sounds similar to LASIK, but it is different from it. LASEK is a type of surgery, laser epithelial keratomileusis, which is a variant of PRK. In this procedure, an epithelial flap is created and then epithelial cells are loosened using an alcohol solution. A laser is used to reshape the cornea and the flap is replaced and secured with a soft contact lens while it heals.

•    RLE: Refractive Lens Exchange, RLE, is a procedure commonly known as clear lens extraction. It is performed for cataracts and involves making a small incision at the edge of the cornea to remove the natural lens of the eye and replace it with a silicone or plastic lens.

Above are some common and important types of laser eye surgery. There are other types of laser surgery available and performed by expert for patients to correct different eye-problems and diseases. Laser Clinic offers expert medical assistance for all patients suffering from any type of eye-problems, eye-diseases.
