In recent years, laser surgery or laser eye surgery has become a more common method of correcting vision.
Learn the details of this process:Laser surgery usually involves reshaping the cornea (the clear layer at the front of the eye).
This is done by using a laser known as an excimer laser.
Several mechanisms are used to correct myopia (myopia disease), farsightedness (farsightedness disease) and astigmatism.
Laser refractive surgery is generally unnecessary.
Typically, you should be 21 age or older, and the prescription must not vary over at least two years.
Types of laser Eye surgery
Your ophthalmologist can discuss with you the various methods of correcting your vision, the advantages and
disadvantages of glasses and lenses, and laser refractive surgery.
Here is a summary of some of the most common types of laser surgery:
LASIK (laser keratoplasty).
Eye surgery has been performed since the mid-1990s and is the most common procedure in the UK. Both myopia and farsightedness can be corrected with LASIK surgeries,
but they may not be suitable for correcting severe cases. Surgeons make an incision through the cornea and then raise a flap of tissue.
The visible part is then reshaped with an excimer laser, and the flap is repositioned.
Optical keratectomy refraction
Photorefractive keratectomy has been performed since the late 1980s, but since the advent of laser core surgeries and laser epithelial keratectomy
photo-refractive keratectomy has been mainly used to correct low-grade medical conditions and the cornea is reshaped with an excimer laser without cutting a flap of tissue.
Laser epithelial keratoplasty:
It is similar to the resection of the cornea with refractive vision, but with the preservation of the surface layer of the cornea as a flap.
It is believed that the preservation of the epithelial layer prevents complications and speeds up recovery.
