Method and apparatus for performing oculoplasty including applying a photosensitizer solution to a human eye surface includes defining a treatment region within the human eye surface. The treatment region is associated with a predetermined spatial pattern. The method further includes irradiating the treatment region with controlled photoactivating radiation. In relation to presbyopia treatments, shrinkage of the paralimbal scleral region near the scleral spur results in improved near focus with no loss in far acuities.

L'invention porte sur une méthode et un appareil d'oculoplastie consistant à appliquer un photosensibilisateur sur la surface de l'oeil après en avoir défini la zone à traiter, laquelle est associée à un motif spatial prédéterminé. On irradie ensuite ladite zone par des rayons photoactivants contrôlés. Dans le traitement de la presbytie ou du rétrécissement de la région sclérale paralimbale proche de l'éperon scléral, on améliore la focalisation proche sans perte de l'acuité à distance.
