Introduction
Pterygium is a membrane-like growth that invades from the conjunctiva onto the cornea, especially common in sunny climates. Modern surgery aims not only to remove the growth but to reconstruct the ocular surface so that recurrence is unlikely and the cosmetic result is excellent. Laser technology has become a valuable tool in achieving that precision.
How the femtosecond laser is used
A femtosecond laser emits ultra-short pulses that create micron-level micro-bubbles within tissue, cutting it with exceptional precision and without thermal damage. In pterygium surgery, the goal is to produce a thin conjunctival graft — approximately 50–70 microns — of planned, uniform dimensions and free of Tenon’s tissue. A graft prepared this way adheres better to the eye, reduces astigmatic distortion, and supports faster, more aesthetic healing.
Precision and reproducibility
Because the laser digitizes the planning of the cut, it delivers a high degree of reproducibility between procedures and shortens the manual cutting time. The result is a consistently thin, well-defined graft — the kind of detail that contributes to a low recurrence rate and a clean cosmetic outcome.
Is laser-assisted surgery right for you?
Laser assistance is one of several tools an experienced cornea surgeon can use, and its suitability depends on the specifics of each case. Prof. Michael Mimouni can advise, during a consultation, whether laser-assisted technique is appropriate for your pterygium and explain how it fits into the overall surgical plan.
