Corneal medicine

The cornea: treating it,
not just reshaping it

When the eye is no longer only a matter of glasses.

Most of this website is about reshaping a healthy cornea to reduce your dependence on glasses. But the cornea is also living tissue, which can be weakened, deformed or damaged by disease. The aim then changes in nature: it is no longer about correcting an optical error, but about treating a surface, stabilising a structure, and restoring the eye’s clarity and comfort.

This section brings together the situations where the cornea calls first for medical care. The approach remains the same as for the rest of my practice: the indication comes before the technique, every cornea is mapped before any decision, and the limits of a treatment are set out to you just as much as its benefits.

Three areas

Corneal medicine covers three areas. I am opening the first today; the other two will follow to expand this section.

01

The corneal surface
— PTK

Available

Some conditions affect the most superficial layer of the cornea: they cause pain, fluctuating vision and persistent discomfort. Phototherapeutic keratectomy (PTK) can, in selected cases, treat this surface with the laser.

02

Keratoconus

Coming soon

Keratoconus is a progressive deformation of the cornea, which thins and bulges. Detecting it early and stabilising it changes its course.

03

The corneal
graft

Coming soon

When the cornea is too deeply affected to be treated at the surface alone, a graft — partial or full — becomes an option.

A common thread

What links these situations is that a diseased or fragile cornea cannot be approached like a healthy eye that one wishes to free from glasses. Here the decision is medical before it is optical. It takes into account the possible course of the disease, day-to-day comfort, and the fact that vision, here, is monitored over time: follow-up is part of the treatment.

One laser, two intentions

A point that often comes as a surprise: the same excimer laser that corrects myopia is also used to treat the surface of the cornea. The tool is identical; the intention is quite different.
