Lasik Vision Surgery: How It May Help You See Into The Future
Refractive surgeries are cosmetic, elective procedures performed to reshape corneal tissue and correct refractive errors so that eyeglasses or contact lenses are no longer needed. Current procedures include radial keratotomy, photorefractive keratectomy (PFK), and vision surgery.

Among the different refractive surgeries, vision surgery is considered as one of the most convenient and has shorter recovery time compared to photorefractive keratectomy or PRK.

Statistics show that nearly 99% of patients who used to wear eyeglasses can do without them after undergoing vision surgery and the visual acuity rates more than 99% as well.

Lasik vision surgery combines delicate surgical procedures and laser treatment. A flap is surgically created and lifted to one side. A laser is then applied to the cornea to reshape it. This type of refractive surgery alters the major optical function of the eye and thereby carries certain surgical risks.

You need to fully understand benefits, potential risks and complications, common side effects, and limitations of the procedure.

Lasik vision surgery does not alter the normal aging process of the eye. If the reason for the procedure is occupational vision requirements, the results must satisfy both the patient and the employer. Precise visual outcome cannot be guaranteed with certainty. Typically, patients must be at least 18 years of age.
The corneal structure must be normal and refractive error stable.

Patients are required to discontinue using contact lenses for a period

LASIK: Revolutionising correction of refractive errors
LASIK, an unprecedented advancement in eye care, offers people a safe and simple opportunity to see the world clearly, minus the inconvenience or discomfort of scratched or lost contact lenses, or the blocked side vision of spectacles. In simple term LASIK is a revolutionary laser technique for correction of refractive errors.
LASIK surgery works wonders for Packers' Ferguson
Ferguson said he went to three doctors seeking a panacea for the headaches. One suggested that LASIK surgery probably would solve his eye problem and just might curb the headaches.
New, Improved LASIK Surgery
Just how much better this new ?wavefront-guided LASIK? works isn't proven yet, but it's causing excitement among eye surgeons who say the three-dimensional maps let them customize treatment in a way never before possible.
Opening Your Eyes To LASIK
More and more people are going under the laser to shed their glasses and contact lenses. So the Eye Surgery Education Council has issued new guidelines to help patients determine whether they could be candidates for laser eye surgery.
BLADE-FREE LASIK SURGERY
Are you near-sighted? Far-sighted? LASIK eye surgery could rid you of your glasses. But if fear of going under the blade is stopping you -- stop worrying. Now, a new blade-free approach.

before the procedure, preferably 2 to 3 weeks for soft lenses and 4 weeks for hard lenses.

Patients with conditions that are likely to adversely affect corneal wound healing, such as corticosteroid use, immunosuppression, are not good candidates for the procedure. Any superficial eye disease must be diagnosed and fully treated before a refractive procedure.

Diagnostic Overview

An improvement over PRK, particularly for correcting high or severe myopia (nearsightedness), a refractive error in which the focus of light rays from a distant object is anterior to the retina, Laser-assisted In Situ Keratomileusis, involves flattening the anterior curvature of the cornea by removing a “stromal lamella” or layer. The surgeon creates a corneal flap with a microkeratome, which is an automatic corneal shaper similar to a carpenter's plane. The surgeon retracts a flap of corneal tissue less than one-third of the thickness of a human hair to access the corneal stroma and then uses the excalculated measurements. The corneal flap, a naturally adhering bandage, is rolled back and repositioned.

LASIK also appears to be an effective, predictable, stable, and safe procedure for correcting residual myopia after cataract surgery. This type of eye surgery causes less postoperative discomfort, has fewer side effects, and is safer than PRK. The patient has no corneal haze and requires less postoperative care. However, the cornea has been invaded at a deeper level, and any complications are more significant than those that can occur with PRK.

DLK is a peculiar, noninfectious, inflammatory reaction in the lamellar interface after vision surgery. DLK is characterized by a white, granular, diffuse, culture-negative lamellar keratitis occurring in the first week after surgery. Studies suggest that, because no single agent appears to be solely the cause of DLK, the cause is multi-factorial.

Lasik Enhancements

With various technological developments, enhancements have been created. These enhancements are surgical operations from improved technology and software used to treat a wider range of myopia, hyperopia, and astigmatism in eyes with a history of refractive surgery.

Indeed, vision surgery can be very effective especially if the patient learns how to administer self-care after the procedure. The nurse, social workers, family and others should collaborate to assess the patient's home condition and support system to facilitate the healing process after the operation.
