What Can LASIK Correct
LASIK corrects vision problems by correcting corneal irregularities that lead to myopia or hyperopia, with or without astigmatism.
In a “normal” eye, light passes through the cornea and is focused directly onto the retina (back of the eye). If the light focuses in a different area of the eye, this will result in one of three conditions:
- Myopia (Nearsightedness) – When your eye is longer than a normal eye with a steeper cornea, light is focused in front of the retina. This will make it difficult to see distant images well.
- Hyperopia (Farsightedness) – When your eye is shorter than a normal eye and has a flatter cornea, light is focused behind the retina. This makes it difficult to see objects close-up.
- Astigmatism – When the shape of your cornea is uneven, images can be focused on the retina at irregular intervals, causing blurred vision. This condition can be found in people who also have myopia or hyperopia.
Presbyopia is a condition that tends to occur to most people after age 40. As we age, our once supple lenses begin to stiffen, making it difficult to focus on objects close-up. This starts slowly but can gradually become worse over time. This is why you may see many low-level “prescription reading glasses” displays in retail stores or drugstores.
LASIK Monovision is sometimes used to resolve presbyopia by correcting one eye for close-up vision and the other eye for distance vision. It can take a little time to adapt to having this type of vision correction, which is why we often test the process using contact lenses to make sure our patients will be happy with the outcome.
