Does LASIK correct presbyopia?

LASIK does not directly correct presbyopia, which is the age-related, natural loss of near vision that affects most people after the age of 40. However, some people may undergo LASIK using a technique called "monovision" to reduce their reliance on reading glasses.

The primary goal of LASIK is to correct refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism by reshaping the cornea [1]. Conversely, presbyopia is caused by the stiffening of the eye's natural lens and the loss of its elasticity as one ages, making it difficult to focus on close objects [1].

Understanding Presbyopia and Its Impact

Presbyopia is a natural condition that occurs with aging, as the eye's lens gradually loses its flexibility. This makes it difficult for the eye to change the shape of the lens to focus on nearby objects, resulting in blurred vision when reading or performing tasks that require close vision [1]. Even people who have excellent distance vision may require reading glasses after approximately age 40 due to presbyopia [1].

LASIK and Monovision as a Solution for Presbyopia

Although LASIK does not directly treat presbyopia, the monovision technique can be an option for some individuals. In this technique, one eye is corrected for distance vision, while the other eye is left slightly nearsighted or is corrected for near vision [1]. The brain learns to adapt to this difference, using the nearsighted eye for close-up tasks while the other eye is used to see distant objects [1].

It is important to note that monovision is not suitable for everyone [1]. Before deciding on this procedure, an ophthalmologist may recommend trying monovision with contact lenses to evaluate your ability to adapt to this type of correction [1].

What to Expect After LASIK if You Have Presbyopia

If you undergo LASIK to correct other refractive errors, you will likely still need reading glasses after age 45 due to presbyopia, even if your distance vision is excellent [2]. The goal of LASIK is to reduce or eliminate the need for glasses or contact lenses for distance vision, not to correct presbyopia [1].

It is essential to have realistic expectations about what LASIK can achieve. Discuss your visual needs and lifestyle with your ophthalmologist to determine the best option for you [1].

Are You a Good Candidate for Monovision LASIK?

To determine if you are a good candidate for monovision LASIK, an ophthalmologist will perform a comprehensive eye exam and evaluate your general eye health [1]. Some basic requirements include being 18 years of age or older (preferably over 21), and having a stable glasses prescription for at least one year [1]. The cornea must also be thick and healthy enough, and overall eye health must be good [1].

The ophthalmologist will discuss potential risks and benefits with you, including any side effects such as dry eyes or glare around lights, which usually disappear over time but may persist in rare cases [1].
