Clear Vision Without Glasses or Contacts: Laser Eye Surgery

Laser eye surgery is a way to correct your vision permanently, so you don’t need to wear glasses or contact lenses anymore. It’s a popular choice because it works well and is convenient.

Types of Laser Eye Surgery

LASIK (Laser-Assisted In Situ Keratomileusis)

  • Procedure: A small flap is made on the eye’s surface, then a laser reshapes the underlying part of the eye.
  • Recovery: Fast, with most people seeing better within 24 hours.
  • Best For: Nearsightedness, farsightedness, and astigmatism.

PRK (Photorefractive Keratectomy)

  • Procedure: The top layer of the eye is removed, then a laser reshapes the underlying part.
  • Recovery: Slower than LASIK, taking a few weeks to fully heal.
  • Best For: People with thin corneas or certain eye shapes.

SMILE (Small Incision Lenticule Extraction)

  • Procedure: A small cut is made, and a piece of tissue inside the eye is removed to reshape it.
  • Recovery: Quick, similar to LASIK.
  • Best For: Nearsightedness and astigmatism.

What Is the Process of Laser Eye Surgery?

Laser eye surgery is a medical procedure designed to correct vision problems, such as nearsightedness, farsightedness, and astigmatism. Here is a simple explanation of the process:

Steps in Laser Eye Surgery

Initial Consultation

  • Eye Examination: The doctor will check your eyes to see if you are a good candidate for the surgery.
  • Discussion: You will talk about your medical history and any eye issues you have had. The doctor will explain the procedure and answer any questions.

Preparation Before Surgery

  • Stop Using Contacts: If you wear contact lenses, you might need to stop using them for a few weeks before the surgery. This helps your eyes return to their natural shape.
  • Eye Drops: You may be given eye drops to use before the surgery.

Day of Surgery

  • Arrival at Clinic: You will arrive at the clinic, and the staff will prepare you for the procedure.
  • Anesthesia: Numbing drops will be put in your eyes so you won’t feel any pain during the surgery.

During the Surgery


  • Flap Creation: A small flap is made on the surface of your eye.
  • Laser Reshaping: The laser reshapes the underlying tissue of the cornea to correct your vision.
  • Flap Replaced: The flap is put back in place to heal.


  • Surface Removal: The outer layer of the cornea is removed.
  • Laser Reshaping: The laser reshapes the cornea.
  • Bandage Contact Lens: A soft contact lens is placed on the eye to protect it while it heals.


  • Small Incision: A tiny cut is made in the cornea.
  • Tissue Removal: A small piece of tissue is removed to reshape the cornea.

After the Surgery

  • Recovery Area: You will rest for a short time in the clinic.
  • Post-Surgery Check: The doctor will check your eyes to make sure everything is fine.
  • Instructions: You will receive instructions on how to care for your eyes, including using eye drops and avoiding certain activities.

Recovery Period

  • Follow-Up Visits: You will have follow-up appointments to check on your healing.
  • Healing Time: Most people notice better vision within a few days, but complete healing can take a few weeks.
  • Temporary Effects: You might experience dry eyes, glare, or halos around lights, but these usually go away as you heal.

Which Conditions Are Treated by Laser Eye Surgery?

Laser eye surgery is used to treat several common vision problems. Here are the main conditions that can be corrected:

1. Nearsightedness (Myopia)

  • Description: People with nearsightedness can see nearby objects clearly, but distant objects appear blurry.
  • Correction: Laser eye surgery reshapes the cornea so that light focuses correctly on the retina, improving distance vision.

2. Farsightedness (Hyperopia)

  • Description: People with farsightedness can see distant objects clearly, but nearby objects appear blurry.
  • Correction: The laser reshapes the cornea to allow light to focus properly on the retina for clearer close-up vision.

3. Astigmatism

  • Description: Astigmatism occurs when the cornea is irregularly shaped, causing blurred or distorted vision at all distances.
  • Correction: Laser eye surgery smooths out the irregular shape of the cornea, allowing light to focus correctly on the retina.

4. Presbyopia

  • Description: This age-related condition makes it difficult to see close objects clearly. It usually affects people over the age of 40.
  • Correction: While laser eye surgery can’t directly fix presbyopia, there are techniques like monovision LASIK, where one eye is corrected for distance vision and the other for near vision.

5. Keratoconus (in early stages)

  • Description: A progressive condition where the cornea thins and bulges into a cone shape, causing distorted vision.
  • Correction: In the early stages, laser eye surgery combined with other treatments like corneal cross-linking can stabilize the condition and improve vision.

Benefits of Laser Eye Surgery

Laser eye surgery offers numerous advantages for individuals seeking to improve their vision. Here are the key benefits:

Improved Vision

  • Enhanced Clarity: Most patients achieve 20/20 vision or better after laser eye surgery, significantly improving their ability to see clearly without glasses or contact lenses.

Long-lasting Results

  • Permanent Correction: Unlike glasses or contacts that need regular updates and replacements, laser eye surgery provides a permanent solution to vision problems.

Quick Recovery Time

  • Rapid Healing: Most people experience improved vision within a few days, with full recovery typically occurring within a few weeks.


  • No More Glasses or Contacts: Eliminates the need for daily maintenance and the inconvenience of wearing glasses or contact lenses.
  • Active Lifestyle: Easier to participate in sports and outdoor activities without the worry of glasses falling off or contacts drying out.

Cost-Effective in the Long Run

  • Savings Over Time: Although the initial cost is higher, the long-term savings on glasses, contact lenses, and cleaning solutions can make laser eye surgery more economical.

Enhanced Safety

  • Reduced Risk of Eye Infections: Fewer eye infections compared to wearing contact lenses, which can sometimes lead to serious eye issues if not handled properly.

Improved Self-Confidence

  • Aesthetic Benefits: Many people feel more confident and comfortable with their appearance without glasses.
  • Comfort: Enjoy the freedom of clear vision without the hassle of glasses or contacts.

Advanced Technology

  • Precision and Customization: Modern laser eye surgery techniques use advanced technology, allowing for highly precise and customized treatment tailored to each patient’s specific vision needs.

Is Laser Surgery the Best Option for You?

Deciding if laser eye surgery is right for you depends on a few important factors. Here’s a simple guide to help you decide:

Things to Think About

Vision Needs

  • Current Vision Problems: Laser eye surgery can fix nearsightedness, farsightedness, astigmatism, and early-stage keratoconus.
  • Age: You should be over 18 and have had a stable vision prescription for at least a year.

Eye Health

  • Corneal Thickness: Your cornea needs to be thick enough for LASIK. If it’s too thin, PRK might be a better option.
  • Overall Eye Health: Your eyes need to be healthy. Conditions like severe dry eyes, glaucoma, or certain retinal diseases might make you unsuitable.

General Health

  • Medical Conditions: Diseases like diabetes, autoimmune diseases, or a history of eye infections could affect your suitability.
  • Pregnancy: It’s often best to wait until after pregnancy due to hormonal changes that can affect vision.


  • Active Lifestyle: If you play sports or lead an active life, laser eye surgery can be very convenient.
  • Occupation: Certain jobs, like pilots or athletes, can benefit from clear vision without glasses or contacts.


  • Realistic Goals: Know that while most people get 20/20 vision, some may still need glasses for certain tasks.
  • Risks and Side Effects: Understand and be okay with potential risks like dry eyes, glare, or trouble seeing at night.

Financial Considerations

  • Cost: Laser eye surgery can be expensive and is usually not covered by insurance. However, it can save money in the long run by reducing the need for glasses or contacts.

Steps to See if You’re a Good Candidate

Consultation with an Eye Doctor

  • Comprehensive Eye Exam: The doctor will check your eye health and vision to see if you’re a good candidate.
  • Discussion of Options: The doctor will explain different types of laser surgery and suggest the best one for you.

Learn About the Procedure

  • Understand the Process: Learn what the surgery involves, how long it takes to recover, and how to care for your eyes afterward.
  • Ask Questions: Ask any questions you have about the surgery, risks, and what to expect.

Consider Alternatives

  • Other Vision Correction Methods: Think about other options like glasses, contact lenses, or non-laser surgeries if laser eye surgery isn’t suitable for you.


Q1. What Does Laser Eye Surgery Do?

A1. Laser eye surgery uses a laser to change the shape of your eye’s surface. This helps fix problems like being short-sighted (can’t see far away), long-sighted (can’t see up close), and astigmatism (blurry vision). It can also help with presbyopia, which is difficulty seeing up close as you get older.

Q2. Is Laser Eye Surgery Painful?

A2. Most people do not feel pain during laser eye surgery. You might feel some pressure, but your surgeon will put numbing drops in your eyes to make you comfortable. After the surgery, you might feel some discomfort or mild pain when the numbing drops wear off.

Q3. Is Laser Eye Surgery Safe for Eyes?

A3. Laser eye surgery is generally safe, and most people are happy with the results. Side effects like dry eyes and temporary vision issues (like glare) are common but usually go away after a few weeks or months. In rare cases, these issues might last longer.

Q4. Is Laser Eye Surgery Permanent?

A4. Laser eye surgery usually provides permanent vision correction. However, as you get older, your eyes might change and you could develop new vision problems. The surgery’s effects are permanent, but it doesn’t stop age-related changes in your eyes.

Q5. What Is the Best Age to Do LASIK?

A5. The best age for LASIK surgery is generally between 25 and 40 years old. By 25, your glasses or contact lens prescription is likely stable, which is important for a good LASIK candidate.
