Problems solved by technology

[0003] Furthermore, since surgical procedures typically occur when the eye is at elevated intraocular pressure, or IOP, any intraoperative measurement without normalized IOP does not correspond to the size of the anatomical features as when the eye is in its normal or natural state

Abstract

Systems and methods for capturing intraoperative biometry and/or refractive measurements include a sensor or valve associated with the eye and configured to detect a pressure of the eye. The system also includes an intra-op diagnostics device including a control unit arranged to actuate the intra-op diagnostics device to capture the intraoperative biometry and/or refractive measurements when the sensor or valve detects pressure within a predetermined pressure range.

Description

technical field [0001] The present disclosure relates to systems and methods for intraoperative eye refraction measurement, and more particularly to systems and methods for intraoperative eye refraction measurement using a smart intraocular pressure valve and tonometer. Background technique [0002] A typical phacoemulsification surgical procedure includes preoperative optical analysis of the eye. The pre-surgical analysis includes measurements of tissue and anatomical features when the eye is intact and intraocular pressure is at a natural or normal level. Based on the pre-surgical analysis, a surgical plan is created. The surgical plan takes into account the tissue of the eye and the dimensions of the different anatomical features. Furthermore, based on this, the refractive power of the replacement lens is also selected. However, during a surgical procedure, in which tissue is removed and manipulated, the dimensions of various anatomical features may change, which may a...
