A method implemented in an ophthalmic surgical laser system that employs a resonant scanner, scan line rotator, and XY- and Z-scanners, for forming a corneal flap in a patient's eye with improved bubble management during each step of the flap creation process. A pocket cut is formed first below bed level, followed by the bed connected to the pocket cut, then by a side cut extending from the bed to the anterior corneal surface. The pocket cut includes a pocket region located below the bed level and a ramp region connecting the pocket region to the bed. The bed is formed by a hinge cut and a first ring cut at lower laser energies, followed by a bed cut and then a second ring cut, which ensures that any location in the flap bed is cut twice to minimize tissue adhesion. The side cut is formed by multiple side-cut layers at different depths which are joined together. All cuts are formed by scanning a laser scan line generated by the resonant scanner.

A method implemented in an ophthalmic surgical laser system for forming a corneal flap in a patient's eye with improved bubble management. The flap includes a horizontal bed and a vertical or near vertical side cut around the periphery of the bed except for an uncut hinge area. The side cut has a bubble barrier layer that can prevent bubbles formed by the laser-tissue interaction from escaping into an interface between the corneal and the patient interface lens. In some embodiments, the bubble barrier layer is a thin uncut layer, located in the epithelium of the cornea, that separates the side cut into two portions. In other embodiments, the side cut does not reach the anterior corneal surface, leaving an uncut bubble barrier layer located with the epithelium. In other embodiments, an additional side cut portion is formed through the uncut bubble barrier layer as the last step.

A system includes an actuator, one or more diagnostic devices configured to make ophthalmic measurements, and one or more treatment devices configured to assist in performing an ophthalmic treatment on an eye of a patient. A controller is coupled with the actuator and configured to cause the actuator to move the one or more diagnostic devices and the one or more therapeutic devices into and out of a region in front of the eye of the patient. The ophthalmic treatment may be a LASIK or SMILE treatment with ametropia and / or eye geometry measured using a diagnostic device.

This invention discloses an intelligent recommendation and optimization method for refractive surgery types based on corneal biomechanics, relating to the fields of intelligent medical decision-making and ophthalmic refractive surgery planning. After collecting preoperative feature sets of patients, this invention outputs a range of potential surgical procedures through a preliminary screening model that integrates a rule engine and LightGBM. By dividing the historical feature sets of four surgical procedures—ICL, SMILE, LASIK, and SURFACE—a two-stage classification and prediction framework is constructed. First, it distinguishes between ICL and corneal refractive surgery, and then further subdivides the corneal refractive surgery types. During training, optimization models are employed using five-fold cross-validation and SMOTE to output recommended surgical procedures. An interpretability force graph is drawn based on SHAP values ​​to improve the accuracy and safety of surgical procedure recommendations. This invention is the first to systematically incorporate corneal biomechanical parameters into a refractive surgery prediction model, achieving intelligent recommendation within a unified framework for multiple surgical procedures. It provides a reliable auxiliary decision-making basis for refractive surgery planning and has broad application value.
