Farsightedness up to +6.00 diopters. Generally, eye doctors will set their limits at +6 for farsightedness, -12 for myopia and 6 diopters for astigmatism. However, not all laser intensities are the same, so there is some room for maneuver. There are general rules that can describe who is a good candidate for LASIK based on vision measurements.
Irregular astigmatism is more difficult to treat with refractive surgery, and LASIK is generally not an option. But how can you tell if you're a good candidate for LASIK? Here are some of the criteria that make you a good candidate for LASIK surgery. LASIK is successful in treating astigmatism for most people, as long as it's the right type and is within the limits of treatment. Objects in the line of sight may be blurry because your eyes can't focus light when you have astigmatism.
You may be a candidate for laser-assisted in situ keratomileusis (LASIK) in situ (LASIK) if you have mild to moderate astigmatism. While LASIK can be used to correct many vision problems, to achieve the best results, your prescription should not be too high (whether you are nearsighted, farsighted, or have astigmatism). You may be wondering, “Am I a good candidate for LASIK? You might also ask yourself, “Which prescription is too high for LASIK? The treatment limits for LASIK are quite generous, so even astigmatism that is considered severe may fall within them. There is also no upper age limit for LASIK surgery, and many adults are satisfied with the results of LASIK starting at age 40.
In general, excimer lasers used during LASIK are approved by the FDA to correct prescriptions of up to approximately +6.00 diopters of farsightedness, -12 diopters of myopia and 6.00 diopters of astigmatism. Irregular astigmatism is the result of eye trauma or certain corneal conditions, such as keratoconus, marginal pellucid degeneration, epithelial basement membrane dystrophy, and others. You should contact your doctor if you have a refractive eye condition, such as astigmatism, regardless of how you decide to treat it. Astigmatism often goes hand in hand with other refractive eye conditions, such as nearsightedness and farsightedness.
