Topolaser (Topography-Guided Excimer Laser): What Is It?

Topography-guided laser treatment is a fully customized excimer laser procedure planned according to the individual contour map (topography) of your cornea. The goal is to correct surface irregularities on the cornea, improve visual quality, and create a more regular optical surface — particularly in conditions such as keratoconus that distort the corneal surface.

Unlike standard laser procedures, this approach uses three-dimensional topographic data from your cornea. Because every patient's corneal architecture is unique, the treatment plan is tailored individually.

How Does It Work?

    1. A detailed map of the cornea is created.
      Specialized topography devices record the cornea's irregularities, surface variations, curvature changes, and asymmetries at micron-level precision.

    2. A personalized ablation plan is generated using computerized simulation.
      This plan determines exactly how much tissue is to be removed from each area, with precision down to one-thousandth of a millimeter.

    3. Treatment is delivered with the excimer laser.
      The laser is applied only to the areas that require correction. The goal is to bring the cornea as close as possible to the smoothest achievable optical surface.

When Is Topolaser Used?

  • If the irregularity on the corneal surface following keratoconus is pronounced
  • If visual quality has not improved sufficiently after CXL (cross-linking)
  • In patients with irregular astigmatism
  • If the corneal surface has become misshapen following trauma, infection, or surgery
  • If contact lens tolerance is poor and smoothing of the surface is desired

What Does Topolaser Offer in Keratoconus?

  • A smoother corneal surface
  • Noticeable improvement in vision quality (especially night vision)
  • Reduction in light scatter and glare
  • Greater comfort with contact lens wear
  • Partial reduction in astigmatism

Who Is Not a Suitable Candidate?

  • If corneal thickness is below the safe threshold for laser treatment
  • If the disease is actively progressing (CXL must be performed first)
  • In advanced keratoconus cases
  • If the structural integrity of the cornea poses a risk for laser treatment

Procedure Overview

  • The eye is numbed with topical anesthetic drops.
  • A laser treatment lasting only a few minutes is performed.
  • You are typically discharged on the same day.
  • The surface re-epithelializes within 1–2 weeks.
  • Final visual quality stabilizes over the course of several weeks to months.

Result

  • Topolaser is a customized, advanced excimer laser procedure designed to regularize the cornea's natural shape. In keratoconus and other corneal surface irregularities, it is a valuable option for improving vision quality in suitable candidates.
