“…Lens coloboma is not a true coloboma because, unlike colobomas of the iris or choroid, there is no specific focus of missing tissue [ 1 – 3 ]. However, the lens becomes more spherical in the defective areas, which can cause astigmatism and decreased visual acuity [ 4 ]. It is usually located inferonasally due to failure of the fetal fissure to close at the area.…”

Patient: Male, 27-year-old Final Diagnosis: Lenticular colobomas Symptoms: Decreased vision Clinical Procedure: ICL implantation Specialty: Microbiology and Virology • Ophthalmology Objective: Rare coexistence of disease or pathology Background: The efficacy and safety of the implantable collamer lens (ICL) in correcting high astigmatism have been previously reported. They are commonly used as an alternative to laser refractive surgery due to advantages such as leaving the cornea untouched, inducing fewer higher-order aberrations, resulting in better optical and visual quality, and it is a reversible procedure. We aim to present the outcome of ICL in managing anisometropia without cataract in an eye with unilateral lenticular coloboma. Case Report: A 27-year-old man with a Marfanoid body habitus was seeking refractive surgery for the correction of high astigmatism in the right eye. On presentation, the best corrected visual acuity was 20/30 and 20/20 in the right eye and left eye, respectively. Slit lamp examination indicated inferior lens coloboma extending from the 5 o’clock to the 7: 30 o’clock position in the right eye, after dilation of pupil. Following a complete refractive work-up, a toric ICL implantation was the presumed suitable surgery. Three weeks postoperatively, central vaulting was low, his ICL subluxated inferiorly, and the previously implanted temporal footplates were resting over the lenticular defect inferiorly. A high-resolution ultrasound biomicroscopy confirmed the presence of a ciliary body (CB) cyst at 9 o’clock position. Urgent explantation of the unstable ICL was performed. Conclusions: This case report emphasizes the challenges and limitations associated with ICL implantation in patients with lenticular colobomas and coexisting CB cyst. Selecting smaller lenticular colobomas and avoiding direct interaction between the weak zonules area and the ICL haptics are important steps to ensure the stability of implanted lens.
