RECRUITINGIdentify risk factors for progressive suction loss
Progressive suction loss, the precursors to the loss of suction are quite evident. This study involved reviewing surgical videos and classifying patients into normal and progressive suction loss groups based on diagnostic criteria for progressive suction loss proposed by Huang. The intruding gas, liquid, and conjunctival tissue were analyzed using the ImageJ image processing software. Progressive suction loss was classified into three groups based on severity: Group A, where bubbles and wet spots begin to appear at the contact area between the suction ring and the corneal edge; Group B, where the area of bubbles and wet spots increases, exceeding 5% of the contact area as analyzed by ImageJ, but not spreading to the corneal surface; Group C, where bubbles and wet spots spread to the corneal surface, even affecting the laser scanning area.
