Inclusion criteria
Inclusion criteria: Case group (MFIOL Group) : 1. Children diagnosed with congenital or developmental cataracts who have undergone cataract extraction combined with multifocal intraocular lens (MFIOL) implantation in our hospital. 2. The age at the time of MFIOL implantation should be <=12 years old. 3. It has complete postoperative follow-up records, including key information such as axial length of the eye, visual acuity, and diopter, and the last follow-up time exceeds one year after the operation. 4. Be capable of cooperating to complete the examinations corresponding to the retrospective data extraction required in the research (such as visual acuity, axial length measurement, etc.). 5) Parents or legal guardians agree to the retrieval and analysis of retrospective research data; Control Group One (SFIOL Group) : 1. Children patients diagnosed with congenital or developmental cataracts who have undergone cataract extraction combined with single-focus intraocular lens (SFIOL, such as ZCB00) implantation in our hospital. 2. The age at the time of SFIOL implantation should be <=12 years old. 3. It has complete postoperative follow-up records, including key information such as axial length of the eye, visual acuity, and diopter, and the last follow-up time exceeds one year after the operation. 4. Be capable of cooperating to complete the corresponding checks for retrospective data extraction required in the research. Parents or legal guardians agree to the retrieval and analysis of retrospective research data. Control Group Two (Normal Children Group) : 1. Normal children with no known history of eye diseases and no systemic diseases that can affect the elongation of the eye axis and visual development. 2. Age <=12 years old. 3. Have regular eye examination records from this center, including key information such as axial length of the eye, visual acuity, and diopter, and the follow-up period is matched with that of the case group. 4. Parents or legal guardians agree to the retrieval and analysis of retrospective research data.
Exclusion criteria
Exclusion criteria: 1. Exclusion criteria Children who develop high intraocular pressure, VAO (visual axis opacity), IOL deviation, retinal detachment, endophthalmitis or other serious complications after surgery, which may significantly affect axial changes and visual function. 2. Suffering from microphthalmia (axial length <16 millimeters), optic nerve hypoplasia, macular degeneration and other eye diseases that may independently affect visual function or axial development. 3. Children with severe systemic diseases or syndromes known to affect axial elongation and visual development (such as severe neurological dysfunction, severe retinopathy of prematurity, etc.). 4. Children patients/normal children who lack key follow-up data or cannot be matched.
