Zusammenfassung:	The present invention generally relates to a method for producing silicone hydrogel contact lenses having less optical defects or free of optical defects by subjecting the extraction tray for the formed silicone hydrogel contact lenses to a reciprocating lowering and raising motion thereof to obtain the silicone hydrogel contact lenses. La présente invention concerne de manière générale un procédé de production de lentilles de contact en hydrogel de silicone ayant moins de défauts optiques ou exempts de défauts optiques par soumission du plateau d'extraction pour les lentilles de contact en hydrogel de silicone formées à un mouvement d'abaissement et d'élévation en va-et-vient de celui-ci pour obtenir les lentilles de contact en hydrogel de silicone.
