“Vision is the art of seeing what is invisible to others.” – Jonathan Swift

What is LASIK surgery?

LASIK is a surgical procedure for vision correction. It is a laser refractive surgery that reshapes the front surface - cornea of the eye. This enables light entering the eye to focus on the retina without glasses or contact lenses. LASIK surgery can be helpful for people suffering for nearsightedness, farsightedness or astigmatism.

Possible Causes: 

What is LASIK: 

The full form of LASIK is laser-assisted in situ keratomileusis. People who suffer from myopia, hyperopia or astigmatism get this laser surgery done to correct their vision.  In myopia light rays focus in front of the retina and blur distant vision. We use the term short-sighted as it’s possible for you to see nearby objects clearly, but not those that are far away.  In hyperopia, light focusses behind the retina instead of on it. You are able to see distant objects clearly but near vision is blurry. Astigmatism is a condition of the eye which disrupts the focus of both near and distant vision.

Risk Factors: 

Possible side effects (extremely rare): 

  • Dry eyes: tear production is reduced temporarily after a LASIK surgery. During the first few months which is the healing period your eyes may feel dry. At this time our eye doctor might prescribe eyedrops for your eyes.
  • Glare, halos and double vision: night vision may get affected, with halos around bright lights or double vision. Your vision in dim light may be hazy.
  • Astigmatism: you may require additional surgery, glasses or contact lenses due to uneven tissue removal. 
  • Vision loss: it may happen that you experience loss of vision due to surgical complications. 
  • Under corrections: if less than required tissue is removed from your eye, then your vision will not be as clear as you expected. This happens mostly to people who are near-sighted. 
  • Overcorrections and flap problems: this can cause complications and infections.

Signs & Symptoms: 

Who benefits from LASIK: 

LASIK surgery is a corrective surgery for those people who do not wish to continue wearing glasses or contact lenses and want to have clear vision. If you suffer from myopia, hyperopia or astigmatism, you are a good candidate for the surgery. However, LASIK is not recommended by doctors if you suffer from autoimmune diseases like lupus or rheumatoid arthritis, if your eyesight prescription number is not stable, or in young patients below the age of 18 years and those older, who begin to develop cataract.

Diagnosis: 

LASIK Workup: 

The diagnosis begins with a full eye examination by your ophthalmologist. The objective is to determine if you are a good candidate for LASIK surgery and whether you have certain risk factors.

  • Your doctor will ask you about the medication you are taking currently and if you have any allergies. Also, if you’ve had any previous eye surgery or trauma, you need to share it with the specialist.
  • Evaluation of your vision to check for eye infections, inflammation, dry eyes and enlarged pupils to mention a few conditions.
  • For those who wear contact lenses, doctors advise you to stop wearing them and start using glasses a few days before the surgery. This is done to ensure accuracy of the measurements of your cornea. 
  • The doctor will also measure your cornea, noting the shape, contour, thickness and any anomalies.

Treatment Options: 

Refractive surgery options: 

  • LASIK surgery is performed by a specialist using a laser to remove tissue from the cornea of the eye. The eye surgeon first creates a thin corneal flap using a microkeratome and then pulls it back to work on the corneal tissue. Using a programmed laser, he or she reshapes parts of your cornea. The flap is put back into place and Lasik surgery recovery usually involves healing without stitches. 
  • Some other LASIK surgeries: 
  • Wave front-guided LASIK is used to reduce the chance of after-surgery problems such as glare, blurry vision, and poor night vision.
  • PRK (photorefractive keratectomy) or LASEK (laser epithelial keratomileusis) are two procedures that are used for patients with thin corneas where LASIK surgery is not possible.
  • Epi-LASIK uses a special instrument, the Epi-keratome for patients who are unable to have LASIK surgery.

FAQs: الأسئلة الشائعة:
  • What are the risks of having a LASIK procedure done?

    A: LASIK is a safe and effective way of correcting your vision. You may not have sharp vision initially or you may have dry eyes, increased sensitivity to light, glare, shadows, and seeing halos around lights. However, these go away after a short time.

  • What are the advantages of LASIK surgery?

    A: Most patients are satisfied with the results of their LASIK surgery. LASIK is safe and accurate since it is a computer guided laser treatment. The procedure is quick and painless. In the event you need an enhancement several years after the surgery, it’s still possible.

  • What happens during the procedure?

    A: During the procedure, your doctor will give you medication to help you relax and puts drops in your eye. The procedure generally takes 30 minutes.  A cutting laser cuts a small hinged flap away from the front of your eye, and a programmed laser allows the surgeon to reshape parts of your cornea. The laser beam helps to remove tiny amount of the corneal tissue. Then, the flap is put back in its place.

  • What do I expect after the procedure?

    A: After surgery, your eye might itch, burn and be watery and you might have blurred vision. If you experience pain, you should not worry as your vision will recover quickly. Your doctor might ask you to cover your eye and give you pain medication or eye drops after the procedure. Your vision might not be clear right after the procedure and might take two to three months to heal completely.

  • Is Lasik surgery permanent?

    A: Although Lasik surgery is permanent and restores vision, there could be exceptions when the patient experiences vision issues such as near or farsightedness, blurred vision or astigmatism. This typically happens if there are some complications in the inserted lens. 

    If the vision issue reoccurs, a follow-up Lasik procedure is done to correct it. However, the chances of the problem reoccurring are meagre, and most Lasik surgeries are permanent. It is also important to remember that Lasik could work differently on individuals; so, consult your doctor to know if you are eligible for the procedure.

  • Will I need glasses after Lasik?

    A: Although Lasik surgery is a permanent procedure, some patients may have to wear glasses after it. The surgery is effective in reducing vision issues and restoring vision to a great extent, but it may not completely eliminate the need for glasses or contact lenses.

    There are also certain eye conditions, such as presbyopia, which almost everyone experiences as they age, which may not be treated with Lasik. Thus, the requirement for glasses depends on the extent to which your vision has deteriorated. It's best to speak to your doctor to know more about glasses after Lasik surgery.

  • Is Lasik surgery painful?

    A: In most cases, we use numbing drops before performing surgery so patients don't feel any pain during the procedure. There is no pain after the surgery as well as there are no stitches involved. However, patients may feel some pressure on the eyes which makes it essential to take certain precautions like avoiding contact sports after the surgery.

    Lasik is the most popular and safest technique to correct and restore vision. It is done under prescribed scientific and clinical protocols and has a very high success rate.

  • Do I qualify for Lasik?

    A: While Lasik is a trusted way to correct vision, it may not be suitable for everyone. For instance, Lasik doesn’t work for conditions such as presbyopia, which affects your ability to see close by objects. However, Lasik shows fantastic results for people suffering from myopia or nearsightedness, hyperopia, astigmatism and other vision issues. 

    A good candidate is someone who has had prescription glasses for at least a year and is in good health. People suffering from Lupus, diabetes, or HIV may not qualify for the procedure as the medication for these conditions could affect the patient's immune system. Expectant mothers are also not advised to undergo Lasik surgery. Lastly, Lasik is typically performed on those who are eighteen years and older.
