Can farsightedness be treated with laser surgery?

Hyperopia (farsightedness) is a refractive condition in which parallel light rays, after passing through a relaxed eye, are focused posterior to the retina. It occurs when the eye’s refractive power is insufficient or when the axial length of the eye is too short. In such eyes, the optical focal point lies behind the retina, resulting in blurred retinal images. Consequently, hyperopic eyes often remain in a state of accommodative effort, making them prone to eye strain and fatigue. So, can hyperopia be corrected with laser surgery? Below, we provide answers to this question.

Can hyperopia be corrected with laser surgery?

In general, yes—laser vision correction is an option for hyperopia. If hyperopia results from congenital genetic factors or abnormal prenatal development, leading to significant refractive error that impairs visual function, it is advisable to consult an ophthalmologist at a reputable hospital for a comprehensive evaluation. For patients with isolated hyperopia and no other ocular comorbidities who strongly wish to avoid wearing corrective lenses, laser refractive surgery may be considered.

Additional Information: Causes of Hyperopia

1. Refractive Hyperopia

This type arises from reduced refractive power of the crystalline lens. It commonly occurs as part of normal aging (presbyopia-related changes) or as a pathological consequence of conditions such as diabetes mellitus during treatment. Lens dislocation posteriorly may also induce hyperopia—this may be due to congenital abnormalities, ocular trauma, or disease. Furthermore, aphakia (absence of the lens) leads to high-degree hyperopia.

2. Curvature Hyperopia

This form results from decreased curvature (i.e., flattening) of any refractive surface within the eye’s optical system—most commonly the cornea—and is thus termed curvature hyperopia. Examples include congenital flat cornea or acquired flattening secondary to trauma or corneal disease. Optically, every 1-mm increase in the cornea’s radius of curvature corresponds to approximately +6.00 diopters (D) of hyperopia. In curvature hyperopia, very few corneas retain perfect sphericity; nearly all cases are associated with concurrent astigmatism.

The above provides an overview of whether hyperopia can be treated with laser surgery. We hope this information proves helpful to you.
