Which Type Of Vision Correction Do You Need?

June 3, 2022

Introduction
Nowadays there are multiple options of refractive vision corrections available. About 75% of adults use some form of visual aids such as glasses or contact lenses.

Every vision correction option has its pros and cons. While deciding what the best choice is for you, there should certain things should consider such as your lifestyle, systemic health and personal preference. These parameters can help you distinguish between the various options available for you.

Problems requiring vision correction

Myopia

  • Also known as nearsightedness.
  • Difficulty in seeing objects placed far away
  • Caused due to an abnormally long eyeball or steeper cornea which causes light to be focused in front of the retina

Hyperopia

  • Also known as farsightedness.
  • Difficulty in seeing objects placed near
  • Caused due to an abnormally short eyeball, or flatter cornea which causes the light to be focused behind the retina.

Presbyopia

  • It is farsightedness that develops with age above 40
  • Eyes will lose the ability to shift the focus between close and far objects.

Astigmatism

  • In this condition, the image appears distorted and there may be double vision
  • It is caused due to  the cornea being elongated instead of round.

Vision correction depends on a variety of factors
There are certain factors when it comes to figuring out the right vision correction option for you.

Daily needs
When you experience trouble in reading, driving or certain other daily activities, you need some visual aids such as glasses or contact lenses. But if you want a more permanent procedure which eliminates the hassle of wearing glasses or lenses daily, you should opt for vision correction surgery.

Overall health
Contact lenses or glasses might be difficult to handle when you are already suffering from a chronic condition. Storage and handling of contact lenses becomes tough while you manage your health condition.

Lifestyle
If your lifestyle includes many other activities such as sports, you might prefer contact lenses. If you are a pilot or applying for the navy, glasses will not be suitable for you. In such cases, surgical options are the best.

Vision correction options

There are many vision corrections are available. Some of them are:

  • Glasses
  • Contact lenses
  • Surgical implants
  • Refractive laser surgery

Vision correction surgery

LASIK

  • Most popular vision correction surgery.
  • Gives outstanding outcomes
  • It corrects nearsightedness, farsightedness or astigmatism and presbyopia
  • Reshapes the cornea to allow light to focus correctly on the retina
  • Should have a reasonable corneal thickness to allow the procedure
  • Patients must be over the age of 18
  • People over the age of 50  should prefer other options.

ICL

  • Minimally  invasive and excellent procedure for treating myopia, hypermetropia and astigmatism
  • The procedure includes implantation of Collamer( soft and foldable) lens inside your eye
  • A small incision is made with laser to implant the lens and it doesn’t require any stitches.
  • ICL surgery is a reversible surgery ie. If outcome is not satisfactory one can opt for removal which is also a very safe surgery.

Wavefront-guided LASIK

  • It involves measuring your eyes using a special wavefront laser technology
  • This helps in creating a 3-D image of your eye and is customized to your needs.

SMILE

  • The surgery is different from LASIK
  • Used to correct myopia
  • Surgery involves a small incision, then a small lenticule or coneal tissue is dissected with the help of laser, and this lenticule is then taken out, effectively flattening the cornea.

Photorefractive keratectomy (PRK)

  • Alternative to LASIK
  • It involves reshaping of cornea using laser after removal of the epithelial layer of the cornea. A protective contact lens is placed on the eye to allow fresh epithelium to grow

EpiLasik

  • This involves reshaping the cornea after removal of only the top layer of the cornea. The epithelial layer of the cornea is reattached to the cornea after reshaping it.

Conductive keratoplasty (CK)

  • The procedure involves heat to shrink and tighten the cornea.

Phakic intraocular lenses (IOLs)

  • Surgically implanted lens
  • It is placed in front of the natural lens of the eye.

Refractive Lens Exchange (RLE)

  • It is a replacement of the natural lens with an artificial lens.
