LASIK Eye Surgery For Vision Correction

LASIK (Laser-Assisted in Situ Keratomileusis) is a type of vision correction surgery aimed at treating vision problems caused by refractive errors.

 

A refractive error means that light rays do not bend (refract) correctly inside the eye, leading to blurred vision.

 

The LASIK procedure utilizes a laser to reshape the cornea, which is the transparent part at the front of the eye, to improve how light is focused on the retina, thereby enhancing vision.

 

LASIK is used to correct nearsightedness, farsightedness, and astigmatism, reducing the need for glasses or contact lenses. In many cases, patients no longer need glasses or contacts after the procedure, although some may still require them.

 

In this article, ophthalmology experts at Magrabi Health provide a comprehensive guide to LASIK vision correction surgery and outline the ideal candidates for this procedure.

 

How does LASIK improve vision?

 

For clear vision, light rays must pass through the cornea and lens, where they are bent to focus on the retina. The retina then converts this light into signals that the brain processes to form the final image.

 

In cases of refractive errors, an abnormal cornea shape causes light to bend incorrectly, preventing it from landing properly on the retina, resulting in blurred vision.

 

During LASIK, Magrabi Health surgeons use a laser to reshape the cornea, reducing the abnormal refraction of light and helping it focus correctly on the retina, thereby improving vision.

 

Who is a candidate for LASIK surgery?

 

Not all patients with refractive errors are suitable for LASIK surgery. Candidates for the procedure must meet the following criteria:

 

  • Age: The patient must be at least 18 years old, but ideally, LASIK should be performed after the age of 21 when vision is more stable.
  • Stable eyesight: The patient should not need to change their glasses or contact lens prescription for at least one year before undergoing the procedure.
  • Correctable refractive errors: The type and degree of refractive error must be within the range that can be treated with LASIK.
  • Healthy corneas: The cornea must be healthy and of sufficient thickness, with no significant eye diseases.

 

Patients should also have realistic expectations regarding the outcome. While LASIK significantly improves vision, it may not eliminate the need for glasses or contact lenses in all cases.

 

Certain conditions may disqualify a patient from undergoing LASIK, including:

 

  • Unstable refractive error.
  • Severe dry eyes.
  • Thin corneas.
  • Corneal scars.
  • Keratoconus (a condition in which the cornea is cone-shaped).
  • Advanced glaucoma.
  • Uncontrolled diabetes.

 

Additionally, Magrabi Health ophthalmologists do not recommend LASIK for pregnant or breastfeeding women due to temporary vision changes associated with hormonal fluctuations during these periods.

 

Steps of LASIK surgery

 

Before undergoing LASIK surgery, Magrabi Health ophthalmologists perform a comprehensive evaluation of the patient’s eyes. This includes checking for overall eye health, measuring the refractive error, assessing corneal thickness and shape, and determining whether the patient has dry eyes.

 

At Magrabi Health, the LASIK procedure is performed using the latest surgical techniques to increase the likelihood of success and minimize potential complications. The steps involved in LASIK surgery include:

 

  1. Anesthesia: The eye surgeon uses anesthetic eye drops to ensure that the patient does not feel any pain during the procedure.
  2. Keep the eye steady: An eyelid holder is placed to prevent blinking, and a suction ring is used to keep the eye still.
  3. Creating a corneal flap: The surgeon creates a thin flap by separating the outer layer of the cornea using either a laser or a surgical instrument, and then folds the flap back to expose the underlying corneal tissue.
  4. Reshaping the cornea: The eye surgeon asks the patient to focus on a specific light while the laser reshapes the cornea based on precise measurements taken during the pre-surgery evaluation.
  5. Repositioning the flap: After reshaping the cornea, the surgeon puts the flap back in its normal position, which naturally heals without the need for stitches.

 

The LASIK procedure typically takes about 20 minutes for both eyes.

 

Recovery after LASIK surgery

 

After LASIK surgery, patients may experience some dryness or itching, which is normal and should be resolved within a few days.

 

Magrabi Health eye surgeons prescribe eye drops to prevent infection and assist with healing. Most patients notice significant improvement in their vision within 24 to 48 hours.

 

However, full recovery may take several weeks, during which patients should have follow-up visits at the eye hospital to assess the surgery’s success.

 

The ophthalmology experts at Magrabi Health advise patients to avoid rubbing their eyes and to wear eye shields while sleeping for a few days to protect their eyes during the recovery period.

 

Long-term successful results of LASIK surgery

 

LASIK is a highly successful procedure, with over 90% of patients achieving the desired results and no longer needing glasses or contact lenses.

 

However, patients should be aware that LASIK does not prevent vision problems associated with aging, such as presbyopia, which is common after the age of 40. This means that even after LASIK, many patients may still need reading glasses.

 

LASIK side effects and risks

 

While LASIK is a safe and effective procedure, like all surgeries, it carries some potential side effects. These side effects are usually temporary and include:

 

  • Dry eyes: Dry eyes are a common side effect, typically resolving within weeks but potentially persisting in some cases.
  • Halos and glare: Some patients may notice halos or glare around lights, especially at night, which usually diminishes over time.
  • Unstable vision: It is normal for vision to fluctuate slightly during the healing process.
  • Light sensitivity: Temporary sensitivity to bright light is common after surgery.
  • Double vision: Some patients may experience double vision, particularly in low-light conditions.

 

In rare cases, complications such as eye infections, under-correction or over-correction of vision, or even loss of vision may occur.

 

Patients can minimize side effects and prevent complications by choosing a specialized eye hospital, where experienced surgeons use the latest diagnostic and treatment technologies.
