Inclusion criteria

Inclusion criteria: 1. After an open corneal injury, combined with traumatic cataract or aphakia, corneal laceration suturing has been performed or the corneal wound has closed spontaneously; 2. Underwent phase I/II intraocular lens implantation surgery in our hospital; 3. Intraoperative implantation of a monofocal intraocular lens; 4. Having the results of subjective refraction in our hospital before surgery and the results of subjective refraction after intraocular lens implantation with a follow-up time of >= 1 month.

Exclusion criteria

Exclusion criteria: 1. A history of other severe eye diseases that affect the transparency of the refractive media or corneal curvature, such as keratitis, uveitis, keratoconus, cataracts caused by other known reasons, etc. 2. There is a history of previous corneal injury or refractive surgery, but the corneal damage has recovered and the cornea is completely transparent; 3. A history of fundus diseases or injuries that affect vision; 4. During the follow-up period, occurrences such as intraocular lens displacement or fundus diseases like retinal detachment, choroidal detachment, vitreous hemorrhage, macular hemorrhage or edema, optic neuropathy, etc. 5. Patients whose true corneal curvature data cannot be measured in the IOL Master data measurement.
