4 results about "Phakic intraocular lens" patented technology

The invention relates to a phakic intraocular lens (1), comprising: - an optic (2) with an optical axis (100) that extends perpendicularly to a horizontal axis (110) and a vertical axis (120) of the intraocular lens (1) in plan view, wherein the horizontal axis (110) and vertical axis (120) are located in a tangential plane (130) to an optic upper side (3), wherein the optic (2) has a diameter (D) in plan view, - a haptic (10) connected to the optic (2) and consisting only of a first haptic body (11) and a second haptic body (16), wherein a vertical distance (a5) along the vertical axis (120) from the optical axis (100) to a first centre of mass (S1) of the first haptic body (11) is smaller than a vertical distance (a6) along the vertical axis (120) from the optical axis (100) to a second centre of mass (S2) of the second haptic body (16).

The present invention provides a device 1 that can reduce the risk of angle-to-angle narrowing after ICL (intraocular lens) implantation surgery. [Solution] The device 1 includes a calculation unit 5. The calculation unit 5 (acquisition unit) acquires at least the preoperative AOD (preoperative angle of view) from the patient before ICL insertion. The calculation unit 5 (calculation unit) calculates the vault threshold using the acquired preoperative AOD, based on a threshold calculation formula that calculates a pre-set vault threshold, which is an indicator of narrow angle, with preoperative AOD and vault (distance) as variables. Furthermore, the calculation unit 5 (selection unit) selects the ICL lens size by referring to the calculated vault threshold.
