As a result, the eye possesses excessive refractive power hence light has to be focused before reaching it into the retina. You may get blurred vision for the faraway objects due to the improper focused of light.
- Farsightedness or Hyperopia: It is much identical to myopia excluding the focal points of the rays of light. It is behind the retina which is why nearby objects may be viewed translucent.
- Night sightedness: Another issue is night sightedness when both of the sights become blurred and distorted. It is more prominent if the light is much brighter in dark areas (especially for driving at night).
- Presbyopia: Naturally, the eye’s structure gets changed after 40. With aging certain changes occur to the eyes such as loss of flexibility of the lens. It can be only corrected with laser eye surgery and that has to be performed minutely.

Another type is PRK (Photorefractive Keratectomy) that helps in reshaping of the cornea on own by using a laser. It can correct mild to moderate myopia, astigmatism or hyperopia levels.
LASEK, also known as Laser Epithelial Keratomileusis is much identical to PRK. It also reshapes the cornea by creating and replacing the flap. In the end, a soft contact lens is attached and left to heal naturally.
ALK or Automated Lamellar Keratoplasty is incredible for correcting some degree of hyperopia and severe myopia. Now, it is greatly substituted by LASIK. Typically, the sublayer of the cornea is cut for reshaping and fixing the issue.
RLE or Refractive Lens Exchange is the process for correcting cataracts. A tiny cut is made for removal of the natural lens of the eye at the very corneal edge. It is replaced with the help of the plastic, silicone and synthetic lens.
Refractive lens replacement or clear lens extraction also corrects extreme myopia or hyperopia. Even the patients with dry eyes, small eye issues and thin corneas can be corrected as well.
EpiLASIK is the procedure for separation and replacing of the thing corneal layer. PRELEX (Presbyopic Lens Exchange) is the procedure in which rigid natural lens is replaced by a flexible as well as multifocal lens.
In Intacs or ICR (Intracorneal Ring Segments) 2 crescent-shaped rings made of plastic are inserted at the outermost corneal edge for flattening. It enables the light rays for focussing in the retina. It is widely preferred for treating myopia.
