Objective: To present the visual outcomes and intraocular lens (IOLs) stability after cataract surgery with foldable single piece IOLs in a patient with congenital cataract-microcornea syndrome (CCMC). Case presentation: A 28-year-old woman presented with bilateral microcornea and posterior polar cataract. Her uncorrected (UDVA) and corrected (CDVA) distance visual acuities were 20/100, 20/160 and 20/80, 20/80, respectively. The horizontal cornea diameter was 9.0 mm in both eyes. Anterior chamber angle assessment (ACAA) with Scheie classification showed grade 3 on the superior, inferior, and temporal site and grade 2 on the nasal site in both eyes. On ultrasound biomicroscopy (UBM), the anterior chamber depths were 2.35 mm. OD and 2.41 mm. OS. The axial lengths were 23.28 mm., OD and 22.50 mm. OS with the A-scan ultrasound biometry. The IOLs power calculation with SRK/T formulas was +25.00 diopter OD and +22.50 diopter OS (A-constant 118.4). Phacoemulsification was performed on both eyes. After lens aspiration, ruptured posterior capsule, a common complication occurred. Then anterior vitrectomy was performed. A foldable single piece IOLs without haptic trimming was implanted in the sulcus in each eye. CDVA was 20/63 equally in both eyes. The intraocular pressure was 12 and 14 mmHg. ACAA showed grade 2 and no pigment dispersion. The IOLs had no tilt or decentration. UBM showed the IOLs were in the proper position and were not rubbing the iris. Conclusion: The foldable single piece IOLs without haptic trimming in the sulcus were safely implanted in both eyes with microcornea in CCMC.
