Best Corrective Eye Surgery

In recent decades, medicine made a breakthrough in the treatment of refractive disorders. And laser-assisted corrective eye surgery began to be extremely popular worldwide because of its high success rate and immediate results, balanced by a slight post-operative discomfort and vision risk very low risk.

A concept that began to be used during the last half of the 20th century called corrective eye surgery, is currently the best option to address deficiencies corrective refraction such as myopia, hyperopia and astigmatism. The operation was first performed in Japan at the prestigious University of Juntendo, and back then, was to make a deep incision in the tissue of the cornea, the stroma, and altering the shape of the cornea to to transform it into a better refractive surface.

Types Of Corrective Eye Surgery

One of the first types of corrective eye surgery, RK, which means radial keratotomy, involved the creation of internal and posterior incisions in the body of the cornea to eliminate the deficit of refraction, which caused the problem vision. However, during the period immediately following this procedure, many patients develop a condition known as bullous keratopathy.

But in the 1970s, radial keratotomy was replaced totally, and advanced procedures were developed by scientists over many years, that limits the risk of that which threatens our vision to a minimum, and limits the time it takes to recover and also the post-operative discomfort.

Today, laser corrective eye surgery shows remarkable results in treating people suffering from nearsightedness, farsightedness or astigmatism, however, if a person decides to undergo laser corrective surgery, he or she must meet certain criteria pre -operatively. Therefore, the first criterion that must be taken into account is the patient’s age, as there are some vision deficiencies inherent in old age – for example, after a certain age, you may not have a good view of far or near distance vision in your eyes, and you will probably need to wear reading glasses.

Other vital aspects to bear in mind are the number of dioptres in a patient’s prescription – this is the diopter measurment of glasses or contact lenses. Apart from this aspect, we must bear in mind that laser corrective eye surgery is not the answer to all problems of sight and there are additional problems, which disqualifies the patient for refractive surgery. These concerns may be related to the health of the eyes – scarring or corneal disease, herpetic keratitis, keratoconus, cataracts or glaucoma, or may be related to compications with ones metabolism – AIDS,lupus, rheumatoid arthritis,or diabetic retinopathy. So corrective eye surgery is not suitable for everyone.

As with any other surgery, corrective eye surgery can lead to a series of complications, both minor and serious. Complications can be grouped into those that occur during the operation itself (intraoperative) and those that occur later (postoperative complications).

INTRA-OPERATIVE COMPLICATIONS

Corrective eye surgery employs the use of a microkeratome to create a corneal flap can lead to various complications during surgery. Perforation of the eye, though rare, has been reported to occur. This was associated mainly with higher microkeratome units, and was mainly due to improper assembly. Other complications related to the use of a microkeratome flap include problems such as thin, perforated fins, irregular or free. Small particles can also be conducted under the flap, resulting in the spots in the vision after corrective eye surgery.

Apart from complications due to the use of a microkeratome, there are also intraoperative complications due to the use of a laser. These complications include irregular astigmatism and decentered. With advances in laser technology, there has been a significant decrease in laser-related complications now occur in less than 1% of corrective eye surgery.

POSTOPERATIVE COMPLICATIONS

Different problems in one’s vision may occur after corrective eye surgery. Some patients notice a decrease in best corrected vision after surgery your vision before surgery. This is usually caused by irregular removal of eye tissue. Other vision problems include flashes of vision, halos, glare and double vision. These problems tend to diminish over time. Night vision can also be seriously affected after corrective eye surgery.

Overcorrections Undercorrections and are also common complications of any surgery procedure of the eye. These complications may require the use of glasses or contact lenses after the procedure, or you may have to undergo augmentation surgery.

Flap complications have also been known to occur after the operation. Dislocation of the flap often happens during the first two days after surgery to correct the eye has taken place. Because of this, patients are advised not to rub your eyes and wear an eye shield during the first or second day after corrective eye surgery. This dislocation of the flap can lead to blurred vision and pain in the eyes. If this occurs, the condition must be treated immediately.

Certain types of corrective eye surgery have been largely associated with the occurrence of dry eye syndrome. LASIK, in particular, has an incidence of almost 30% of dry eye syndrome after the procedure. With dry eye, you may feel a burning sensation or blurred vision. This can be treated with eyedrops for more severe cases corrective eye surgery.
