An ocular suction ring for an ophthalmic laser treatment system, comprising: an outer contact ring configured to mate with a patient eye surface; an inner contact ring configured to mate with said patient eye surface; said outer contact ring forms an outer elliptical cylindrical tube having an outer ellipse major axis and an outer ellipse minor axis that configure said outer contact ring with an outer ellipse eccentricity greater than zero; the ocular suction ring being characterised in that: said inner contact ring forms an inner elliptical cylindrical tube having an inner ellipse major axis and an inner ellipse minor axis that configure said inner contact ring with an inner ellipse eccentricity greater than zero; said outer ellipse major axis is coincident with said inner ellipse major axis; said outer ellipse minor axis is coincident with said inner ellipse minor axis; said outer elliptical cylindrical tube comprises an outer distal peripheral edge that is longitudinally curved to conform to said patient eye surface; said inner elliptical cylindrical tube comprises an inner distal peripheral edge that is longitudinally curved to conform to said patient eye surface; said outer contact ring and said inner contact ring are joined together with a contact ring radius to form a patient eye vacuum chamber when said outer distal peripheral edge and said inner distal peripheral edge simultaneously contact said patient eye surface. an outer contact ring configured to mate with a patient eye surface; an inner contact ring configured to mate with said patient eye surface; said outer contact ring forms an outer elliptical cylindrical tube having an outer ellipse major axis and an outer ellipse minor axis that configure said outer contact ring with an outer ellipse eccentricity greater than zero; the ocular suction ring being characterised in that: said inner contact ring forms an inner elliptical cylindrical tube having an inner ellipse major axis and an inner ellipse minor axis that configure said inner contact ring with an inner ellipse eccentricity greater than zero; said outer ellipse major axis is coincident with said inner ellipse major axis; said outer ellipse minor axis is coincident with said inner ellipse minor axis; said outer elliptical cylindrical tube comprises an outer distal peripheral edge that is longitudinally curved to conform to said patient eye surface; said inner elliptical cylindrical tube comprises an inner distal peripheral edge that is longitudinally curved to conform to said patient eye surface; said outer contact ring and said inner contact ring are joined together with a contact ring radius to form a patient eye vacuum chamber when said outer distal peripheral edge and said inner distal peripheral edge simultaneously contact said patient eye surface. said inner contact ring forms an inner elliptical cylindrical tube having an inner ellipse major axis and an inner ellipse minor axis that configure said inner contact ring with an inner ellipse eccentricity greater than zero; said outer ellipse major axis is coincident with said inner ellipse major axis; said outer ellipse minor axis is coincident with said inner ellipse minor axis; said outer elliptical cylindrical tube comprises an outer distal peripheral edge that is longitudinally curved to conform to said patient eye surface; said inner elliptical cylindrical tube comprises an inner distal peripheral edge that is longitudinally curved to conform to said patient eye surface; said outer contact ring and said inner contact ring are joined together with a contact ring radius to form a patient eye vacuum chamber when said outer distal peripheral edge and said inner distal peripheral edge simultaneously contact said patient eye surface.
