TESA-S is a Customized TESA (Trans-Epithelial Surface Ablation) procedure performed using the Schwind Amaris 1050RS excimer laser.
The Schwind Amaris 1050RS laser is currently the highest performing, fastest excimer laser in the market with an unprecedented 7D eye tracker. A shorter treatment time aided by a unique eye tracker produces accurate results.
Prior to the treatment, patients are subjected to measurements by the Schwind Combi Wavefront Analyzer, a powerful diagnostic system that provides complete corneal analysis and treatment planning.
The eye is positioned well before the corneal skin (epithelium) is gently removed using excimer laser. This will allow laser correction to the inner layers of the cornea.
The excimer laser is then used to reshape the inner layers of the cornea, thus correcting the eye’s power.
A bandage contact lens is then placed on the cornea to allow regrowth of the epithelium and is removed within 1 week.
TESA-S+* is a full wavefront-guided TESA-S for patients with poor initial vision quality and night vision. A wavefront-guided treatment is important to maximize vision results for these specific patients.
