Understanding the condition

What is hyperopia?

Hyperopia is a refractive condition characterized by an eye that is too short (axial hyperopia, the most common form) or a cornea that is insufficiently curved (refractive hyperopia). The image of nearby objects forms behind the retina, causing blurred vision mainly up close. At a distance, vision often remains sharp thanks to the focusing ability of the crystalline lens, at the cost of constant muscular effort.

Unlike myopia, which progresses during adolescence, hyperopia often decreases in childhood (as the eye grows) and then remains stable in adulthood. It affects about 25% of the adult population in population-based studies (Beaver Dam Eye Study, Blue Mountains Eye Study). Its prevalence increases with age because the eye’s focusing power gradually weakens, revealing latent hyperopia.

Symptoms and the three forms of hyperopia

The ophthalmologist classically distinguishes three forms based on age and focusing ability:

  • Latent hyperopia: fully compensated by the eye’s focusing effort (typically in young adults). No symptoms at rest, but eye strain during prolonged tasks. PMID 10366072.
  • Manifest hyperopia: partially compensated. Glasses are often helpful for comfort, particularly for children at school.
  • Total hyperopia: cannot be compensated by focusing effort (after age 40–45, or with a stiffer crystalline lens). Glasses are required for sharp vision.

Typical symptoms: blurred near vision (difficulty reading or using a screen), end-of-day headaches, frequent blinking, eye redness and a stinging sensation. In children, severe uncorrected hyperopia can lead to accommodative strabismus and, over time, amblyopia (lazy eye), which is why early vision screening matters.

Surgical options

Operating on hyperopia: available techniques

Refractive surgery for hyperopia is technically more demanding than for myopia. The laser must reshape the periphery of the cornea (making it steeper in the center), which is more prone to long-term regression. Four main techniques are available.

1. LASIK: the reference technique

LASIK corrects hyperopia up to +5 diopters. Visual recovery is gradual over 1 to 3 weeks (slower than for myopia). The precision of the latest-generation laser (MEL 90, EX500) and aberrometry-guided customization help limit halos and glare. Returning to work is usually possible in 2 to 3 days.

2. PRK: surface laser

PRK treats hyperopia up to +4 diopters. It is preferred for patients with a thin cornea or those exposed to eye trauma. Recovery is longer (7 to 14 days), but no corneal flap is created.

3. SMILE for hyperopia (VisuMax 800)

Since 2024, the VisuMax 800 platform has extended the SMILE indication to hyperopia up to +6 diopters. This minimally invasive technique preserves the cornea’s biomechanics. Its main advantage: less postoperative dry eye and greater long-term stability compared with LASIK for moderate hyperopia.

4. ICL EVO phakic implant or PRELEX

For high hyperopia (beyond +6 D) or when the cornea is not suited to the laser, two options are available:

  • Hyperopic ICL EVO: a phakic implant placed between the iris and the crystalline lens, reversible. Available up to about +10 diopters. It requires a sufficiently deep anterior chamber.
  • PRELEX (PREsbyopia Lens EXchange): replacing the clear crystalline lens with a custom-calculated implant. Often offered after age 45–50, especially as presbyopia sets in at the same time. A multifocal or EDOF implant can treat hyperopia and presbyopia simultaneously.

Assessment and pricing

Preoperative assessment and cost of surgery

The preoperative assessment includes: refraction before and after cycloplegia (particularly important for revealing total hyperopia), corneal topography, pachymetry, aberrometry, anterior-segment OCT and a dilated fundus examination. Cycloplegia (pharmacological dilation) is essential in hyperopia to reveal the accommodative component and confirm the actual correction to be treated.

Indicative prices at Dr Tourabaly’s practice: LASIK €1,500/eye (€3,000 for both eyes), PRK €1,250/eye (€2,500 for both eyes), SMILE €1,650/eye (€3,300 for both eyes), PresbyLASIK €1,750/eye (€3,500 for both eyes), ICL EVO surgeon’s fee €1,200/eye + Clinique Sainte-Geneviève fee (€650 + €48 for both eyes) + implant on quotation, PRELEX (multifocal implant) €2,500 to €3,500/eye depending on the implant. Refractive surgery is not covered by the French health insurance system, except in specific cases (high anisometropia, documented intolerance to glasses/contact lenses). Private health plans generally offer a refractive-surgery allowance that can be activated. See refractive surgery pricing.

Consultation with Dr Tourabaly

Dr Moïse Tourabaly sees patients at the Cachan practice (94) to assess hyperopia and discuss the surgical options. Procedures are performed using latest-generation surgical equipment. Hyperopia calls for particular expertise because of the greater variability in tissue response: a detailed assessment and honest information make it possible to choose the technique suited to each patient.

Frequently asked questions

Frequently asked questions about hyperopia surgery

Yes. LASIK corrects hyperopia up to +5 diopters, PRK up to +4 D and SMILE up to +6 D (VisuMax 800). Beyond that, a hyperopic ICL EVO phakic implant or a lens exchange (PRELEX) is preferred. Laser correction requires a cornea of sufficient thickness and a preoperative assessment that includes refraction under cycloplegia.

Laser treatment for hyperopia reshapes the periphery of the cornea to make it steeper in the center. This peripheral zone is more sensitive to the biological process of healing, which explains a visual stabilization over 1 to 3 months, longer than for myopia. Vision returns gradually: reading comfort is often noticed at 1–2 weeks, with full stability at 3 months.

A partial regression is possible with hyperopic LASIK, estimated at 10–20% of patients at 5 years according to the studies (Reinstein, Kohnen). It is linked to a slight natural flattening of the cornea and to changes in the crystalline lens. A laser enhancement can correct this regression in most cases. Intraocular implants (ICL or PRELEX) offer greater long-term stability.

Yes, and this is often the moment when hyperopia becomes disabling (declining focusing ability, associated presbyopia). Two approaches: PresbyLASIK or replacement of the crystalline lens with a multifocal implant (PRELEX), which treats hyperopia and presbyopia at the same time. PRELEX offers lasting stability because the crystalline lens no longer changes. A full assessment with a contact-lens trial can help confirm the choice.

The hyperopic ICL EVO is a collamer lens placed between the iris and the crystalline lens, correcting hyperopia up to about +10 diopters. It is indicated in younger patients (21 to 45 years) with a sufficiently deep anterior chamber. It preserves the cornea and the crystalline lens, is reversible and can be removed during a future cataract operation.

No, except in exceptional cases. In children and adolescents, refractive surgery is contraindicated because the refraction changes naturally (the eye grows and hyperopia often decreases). Management is with glasses, with close monitoring in the event of accommodative strabismus or amblyopia. Surgery would be considered after age 21 and once the refraction has been stable for at least 1 year.
