A review of eye surgeries, comparisons and perceptions of vision

Patients with vision problems often visit a physician who has specific treatment options to treat their problem. However, the best way of treating the patient's vision problem is after the initial consultation, eye evaluation and medical examinations, and this method is generally different from the one that the person considered at the beginning of the referral to the doctor. Today, the demand for eye surgery has increased in young people. Many of these patients are in the 18-year-old age range, whose lifestyles make them unwelcome using glasses and contact lenses. In this case, two methods of laser and lASIK surgery are common eye surgery. This article will explain the common eye surgery as well as the difference between LASIK and LASZK.

LASIK surgery (LASIK)


LASIK surgery is the most common type of laser eye surgery. In this operation, the thin layer (flap) is cut off from the outer surface of the cornea. This layer bends easily to display the inner surface of the stroma or flattening, the inner surface of the cornea. The eximer light is then transmitted to the cornea of ​​the cornea, and the flap eventually returns to its original location. The flap is fixed shortly after surgery without the need for stitches. In this way, the rest of the cornea remains intact, the laser is not transmitted to the cornea, and many patients feel uncomfortable for only a few hours. Recovery of vision occurs very quickly, and the majority of patients wake up in the morning after a 20/20 wide vision surgery.

Laska surgery (LASEK)


In the operation of the lacquer, sometimes known as PRK, the skin or epithelium of the cornea is diluted with 20% alcohol for about 20 minutes to detect stroma or flatulence. Then using a laser, the tissue that needs to be changed to change the surface of the cornea is shaved. After 4 to 5 days, the epithelium begins to repair under the protective lens contact lining. This method, unlike LASIK, does not involve removing a layer of cornea (flap), and is therefore a reference method for surgeons with less experience in LASIK surgery.

The lens is generally suitable for patients who wear glasses and in addition suffer from cornea-like illnesses, such as contact lens infections, which cause wounds and rubbing at the cornea. Surface surgeries can also be used in pathologic treatments in addition to treating eye focus.

Surgery ReLEx SMILE


This surgical procedure is the latest generation of laser eye surgery, which is less likely to be risked than other methods, and does not require a flap to cut and remove skin or epithelium of the cornea. This treatment is performed in a stroma and is performed with a very small incision. When the exact amount of tissue is removed, the surgery ends. This method also applies to patients with mild dryness, a problem that makes people unable to perform LASIK surgery.

This method also provides surgery for patients with weaker eyes. Since 2012, more than 1.2 million ReLEx SMILE surgeries have been performed in the world.

PRESBYOND Laser Blended Vision
This is the most effective way to treat vision problems in the elderly. As the age increases, changes in vision make people use glasses to study, or even use dual-focus glasses. This surgery has a similar resemblance to the three surgical procedures described, with the exception that in this surgery, to increase the depth of the field of view, it is possible to view objects as well as to see nearby objects.

The PRESBYOND Laser Blended Vision method is a remarkable improvement in the techniques used to treat vision when it is studying, less invasive, more secure, and has less side effects. This method also has moderation and reversibility.

Important points you should know before using LASIK or LASIK
The recovery period after LASIK and LASIK surgery varies according to the patient's overall condition and depends on the age and type of surgery. But in general, most patients, one or two days, or a little more, can resume their daily routine after surgery. Patients are unable to drive after surgery, so it is best for the patient to have someone with him to bring him back home. After surgery, patients can not even make up, drink alcoholic beverages or woolen clothes that may produce lint.
