Refractive Surgery

Refractive surgery is a vision correction (specs removal) option for patients who wish to reduce or eliminate their dependence on spectacles or contact lenses offering long term vision correction. It encompasses both laser-based procedures that reshape the cornea and lens-based procedures for more severe refractive errors or presbyopia (age-related near vision loss).

If the curvature of the cornea is not regular or the proportions of the eye are not exact, the light cannot be brought into sharp focus at the back of the eye. This causes a blurry, unfocused vision.Refractive errors occur when the shape of your eye prevents light from focusing correctly on the retina. The most common types of refractive errors include:

Normal Vision:

Vision is the result of the eye refracting incoming light onto the back of the eye, called the retina.

With normal vision the light rays are bend by the cornea, the front part of the eye and the lens inside the eye, exactly in one point directly on the retina, forming a clear image

Myopia (Nearsightedness):

Caused by a cornea that is too curved for the given length of the eye or the eye is too long causing light rays to focus in front of the retina instead of on the retina. This causes distant objects, such as street signs or people across a room, to appear blurry. Near vision objects, such as reading a book or writing text messages on your smartphone, will still be focused without glasses or contacts.

Hyperopia (Farsightedness):

Hyperopia, or farsightedness, is caused by a cornea that is too flat for the given length of the eye or the eye is too short, causing light rays to focus behind the retina instead of on the retina. This causes near vision objects, such as books and smart phones, to appear blurry. Distant vision objects may still be seen more clearly without glasses and contacts.

...
...

Astigmatism:

Astigmatism is caused by a cornea that is shaped more like a rugby ball, instead of round like a basketball. This condition creates many variations of distorted, hazy vision for both near vision and distant vision. Almost all people have some degree of astigmatism, and it often combines with myopia or hyperopia deteriorate. Blurred vision at all distances due to an irregularly shaped cornea or lens, causing light to focus unevenly on the retina.

...

Presbyopia:

Age-related loss of the eye's ability to focus on close objects. This occurs due to the hardening of the natural lens, often requiring reading glasses.

Refractive surgery is suitable for many patients, but not everyone. Here are some key inclusion and exclusion criteria:


Inclusion Criteria:
  • Stable vision for at least 1 year.
  • Over 18 years of age.
  • Presence of myopia, hyperopia, astigmatism, or presbyopia.
Exclusion Criteria:
  • Thin or irregular corneas (depending on the type of surgery).
  • Unstable vision or progressive refractive error.
  • Autoimmune diseases or certain health conditions that may impair healing.
  • Pregnant or breastfeeding women, as hormonal changes can affect vision.

"For patients who may not qualify for laser vision correction, lens-based procedures like ICL or PRELEX may be considered."


Our centre provides a complete range of refractive surgery options, divided into Laser Vision Correction and Lens-Based Procedures.

...

A. Laser Vision Correction

Laser vision correction reshapes the cornea to correct refractive errors. The key procedures include:


1.    PRK (Photorefractive Keratectomy):

PRK is a surface ablation technique that corrects vision by removing the outer layer of the cornea before reshaping it with an excimer laser. This is a great option for patients with thinner corneas.

Advantages
  • No flap creation, reducing the risk of flap-related complications.
  • Suitable for patients with thin corneas or irregularities.
...

2.    LASIK (Laser-Assisted In Situ Keratomileusis):

LASIK is the most commonly performed laser surgery. A thin flap is created in the cornea, which is lifted to allow reshaping of the underlying corneal tissue with an excimer laser.

Advantages
  • Fast recovery with minimal discomfort.
  • Excellent outcomes, with most patients achieving 20/20 vision or better.
...

3.    Bladeless Femto LASIK:

This is an advanced form of LASIK, where a femtosecond laser (VisuMax) is used to create the corneal flap instead of a microkeratome blade. This results in greater precision and safety.

Advantages
  • Blade-free, more precise flap creation.
  • Less risk of complications and faster recovery.
...

4.    SMILE (Small Incision Lenticule Extraction):

SMILE is a minimally invasive procedure that reshapes the cornea by creating and removing a small lenticule of tissue through a tiny incision. It does not require a flap.

Advantages
  • Less invasive, no flap.
  • Faster recovery and less dry eye postoperatively.
...

B. Lens-Based Procedures

Lens-based procedures are often preferred for patients with high refractive errors or those with presbyopia.


1.    ICL (Implantable Collamer Lens):

ICL is a lens implant procedure for patients who are not suitable candidates for laser procedures due to high myopia or thin corneas. The ICL is implanted between the natural lens and the iris to correct vision.

Advantages
  • Reversible and can be replaced.
  • Suitable for patients with higher refractive errors.

2.    Clear Lens Extraction:

This procedure involves removing the natural lens and replacing it with an artificial intraocular lens (IOL). It is similar to cataract surgery and is often used for patients with high hyperopia.

Advantages
  • Permanent vision correction.
  • Can treat both refractive errors and presbyopia.

3.    PRELEX (Presbyopic Lens Exchange):

PRELEX is a lens replacement procedure for patients with presbyopia. It involves replacing the natural lens with a multifocal/trifocal or EDOF (Extended Depth of Focus) IOL or ther newer generation lenses to restore both near and distance vision.

Advantages
  • Corrects presbyopia and other refractive errors.
  • Reduces dependence on reading glasses.

As part of our comprehensive refractive services, we also offer solutions for presbyopia, the age-related condition that reduces the eye’s ability to focus on near objects.

  • Laser Vision Correction for Presbyopia: In some cases, monovision LASIK can be performed, where one eye is corrected for distance vision and the other for near vision.
  • Lens-Based Solutions: Procedures like Presbyopic ICL and PRELEX (Presbyopic Lens Exchange) with the use of multifocal or EDOF IOLs are often the best solutions for presbyopia. Read about IOL Types.
