Understanding Myopia: A Clear Look at Nearsightedness
What is Myopia?
Myopia, commonly known as nearsightedness, is a refractive condition where:
- The eye’s axial length is too long relative to its focusing power
- Or the cornea has an overly steep curvature
This causes light to focus in front of the retina instead of directly on it, resulting in blurry distant vision while near objects remain clear.
Common Symptoms:
- Clear vision for close objects
- Blurry vision for distant objects
- Frequent squinting
- Eye strain and headaches
Quick Facts:
- Affects approximately 30% of the U.S. population
- Often develops during childhood
- Can progress throughout adolescence and early adulthood
Don’t let myopia hold you back from seeing the world clearly!
Diagnostic Techniques
Accurate diagnosis of myopia involves several techniques:
- Visual Acuity Test: Measures how well you can read letters on a standard eye chart.
- Refraction Test: Determines the exact lens power needed to correct your vision.
- Corneal Topography: Maps the curvature of your cornea to detect any irregularities.
- Axial Length Measurement: Uses ultrasound or optical methods to measure the length of your eye.
- Dilated Eye Exam: Allows for a thorough examination of the retina and optic nerve.
Laser Vision Correction Approach
Laser vision correction offers a long-term solution for myopia. The most common procedures are:
LASIK (Laser-Assisted In Situ Keratomileusis)
- A thin flap is created on the cornea
- Laser reshapes the underlying corneal tissue
- The flap is repositioned
- Quick recovery, with most patients seeing clearly within 24 hours
PRK (Photorefractive Keratectomy)
- The outer layer of the cornea (epithelium) is removed
- Laser reshapes the cornea
- The epithelium regrows naturally
- Longer recovery time but suitable for those with thin corneas
SMILE (Small Incision Lenticule Extraction)
- A small lens-shaped bit of tissue is created within the cornea
- This lenticule is removed through a tiny incision
- Minimally invasive with quick recovery
The Laser Vision Correction Process
- Consultation: Comprehensive eye exam to determine candidacy
- Pre-operative Preparations: Instructions on medication and eye care
- Procedure: Usually takes about 15-30 minutes for both eyes
- Post-operative Care: Follow-up visits to monitor healing
Benefits of Laser Vision Correction for Myopia
- Reduced or eliminated dependence on glasses or contact lenses
- Improved quality of life
- Cost-effective in the long run
- Quick procedure with rapid visual recovery
Is Laser Vision Correction Right for You?
While laser vision correction can be life-changing, it’s not suitable for everyone. Ideal candidates are:
- 18 years or older
- Have stable vision for at least a year
- Free from certain eye diseases
- Not pregnant or nursing
Consult with an eye care professional at Burjeel Day Surgery Center, Al Reem to determine if you’re a good candidate for laser vision correction.
