Inclusion criteria
Inclusion criteria: Aged not less than 18 years old; with clear cognitive ability; 22mm <= preoperative axial length <= 26.5mm. Control group: corneal astigmatism <= 1.0D, with L-313 IOL implanted in one eye; observation group 1: cataract patients with corneal astigmatism <= 1.0D, with LS-313MF15 IOL implanted in one eye; observation group 2: regular corneal astigmatism 1.0D~4.0D , cataract patients implanted with LS-313MF15T IOL in one eye (patients with unilateral surgery selected the operated eye, and patients with binocular surgery were selected as the priority operated eye). According to the Emery-Little grading system, the nuclear hardness of both eyes was grade I-IV; the operation went smoothly without complications such as posterior capsule rupture (judgment needs to be made during the operation). The patient agreed to sign the "Subject Informed Consent Form".
