Abstract:
An ophthalmic laser treatment system and method providing for a liquid optical interface (LOI) with a patient eye surface (PES) using an elliptical ocular suction ring (OSR) is disclosed. A disposable ocular patient interface (OPI) provides for simultaneous differential vacuum mating of the PES, OSR, OPI, and an optical window retainer (OWR). The PES, OSR, OPI, and OWR form an enclosed volume in which liquid may be interjected to cover the PES during laser treatment. A vacuum suction pump (VSP) provides controlled vacuum to the OPI ensuring proper differential vacuum mating (DVM) between the PES, OSR, OPI, and OWR during laser treatment. The OWR connects to a laser objective bracket (LOB) via an ocular force sensor (OFS) and an optical separator bracket (OSB). The OFS senses applied pressure to the PES and provides data to a computerized control device (CCD) that limits applied pressure to the PES during laser treatment.

Claim (Index 11):
An ophthalmic laser treatment method, said method operating an interface for an ophthalmic laser treatment system comprising:\n (a) ocular suction ring (OSR) (b) ocular force sensor (OFS); (c) vacuum suction pump (VSP); and (d) computer control device (CCD); wherein: said ocular suction ring (OSR) further comprises an outer contact ring (OCR) having a generally elliptical shape and configured to mate with a patient eye surface (PES); said ocular suction ring (OSR) further comprises an inner contact ring (ICR) having a generally elliptical shape and configured to mate with said patient eye surface (PES); said ocular suction ring (OSR) comprises an outer distal peripheral edge (ODE) that is longitudinally curved to conform to said patient eye surface (PES); said ocular suction ring (OSR) comprises an inner distal peripheral edge (IDE) that is longitudinally curved to conform to said patient eye surface (PES); said outer contact ring (OCR) and said inner contact ring (ICR) are joined together with a contact ring radius (CRR) to form a patient eye vacuum chamber (EVC) when said patient eye surface (PES) is simultaneously contacted with said distal peripheral edge (ODE) and said inner distal peripheral edge (IDE); said vacuum suction pump (VSP) is configured to supply controlled differential vacuum to said patient eye vacuum chamber (EVC); said ocular force sensor (OFS) is configured to sense pressure applied to said patient eye surface (PES) by said ocular suction ring (OSR) via measurement of deflections of said ocular force sensor (OFS); and said computer control device (CCD) is configured to control operation of said laser radiation source (LRS), monitor pressure readings from said ocular force sensor (OFS), and monitor and control applied vacuum pressure to said patient eye surface (PES) by said vacuum suction pump (VSP); wherein said method comprises the steps of: (1) Connecting said vacuum suction pump (VSP) to said patient eye vacuum chamber (EVC); (2) Setting vacuum pressure on said vacuum suction pump (VSP); (3) Positioning said ocular suction ring (OSR) onto said patient eye surface (PES); (4) Activating said vacuum suction pump (VSP) to vacuum mate said ocular suction ring (OSR) to said patient eye surface (PES); (5) Under control of said computer control device (CCD), monitoring vacuum pressure to said patient eye surface (PES) by reading vacuum measurements obtained from a vacuum gauge connected to said vacuum suction pump (VSP); (6) Under control of said computer control device (CCD), monitoring applied pressure to said patient eye surface (PES) by reading pressure measurements obtained by said ocular force sensor (OFS); (7) Performing ophthalmic laser surgery with a laser radiation source (LRS) operated by said computer control device (CCD) and positioned by said laser objective bracket (LOB); (8) Opening an ocular suction ring vacuum relief valve (OSR-VRV) in said vacuum suction pump (VSP) to disengage said ocular suction ring (OSR) from said patient eye surface (PES); (9) Undocking said ocular suction ring (OSR) from said patient eye surface (PES).
