Correction of Refractive Vision Errors

Correction of Refractive Vision Errors

The goal of correcting refractive vision errors is to help individuals see more clearly by adjusting the eye’s focusing power. In general, this is done by modifying how light is refracted: reducing the eye’s focusing power in individuals with myopia (nearsightedness) and increasing it in those with hyperopia (farsightedness).

 

1. Eyeglasses

This is the most commonly used method. However, many people are unable to rely on glasses for vision correction for various reasons, such as having significantly different prescriptions in each eye, or due to occupational needs or sports activities.

2. Contact Lenses

Another popular option, but it requires careful hygiene to avoid complications such as corneal infections, which can be severe and may even lead to vision loss. Additionally, some individuals cannot wear contact lenses due to allergies to the lenses or cleaning solutions. Certain environments, such as dusty areas, and activities like swimming, may also make contact lens use unsuitable.

3. Refractive Surgery (ReLEX SMILE, Femto LASIK, PRK)

Suitable for individuals who prefer not to wear glasses-whether due to discomfort, dizziness, thick lenses, or inability to wear contact lenses because of allergies, dry eyes, or eye inflammation. Modern technology has advanced significantly, allowing for bladeless surgery using lasers (Femtosecond Laser and Excimer Laser) throughout the procedure. These methods are highly safe, precise, and offer quick recovery after surgery.
