Materials and method: The records of 40 patients operated for bilateral congenital cataract at GÜTF Eye Clinic between 2010-2018 were retrospectively analyzed. Peroperatively capsulotomy, lens aspiration, posterior capsulotomy and anterior vitrectomy were performed. Primary iol implantation was performed in cases over one year of age. Secondary IOL implantation was performed at 2 years of age unless contraindicated. Visual acuity, intraocular pressure, presence of strabismus, amblyopia, nystagmus and surgical complications were evaluated.

Results: The mean follow-up period was 4 years (1 month-8 years). 22 of the cases were male (55%) and 18 were female (45%). Seventeen patients (42.5%) underwent surgery before 3 months of age, and 23 patients (57.5%) underwent surgery after 3 months of age. 8 out of 30 patients who left aphakic went for secondary IOL implantation at the mean age of 5 years. The mean postoperative BCVA was 0.4 logMAR±0.4 (P +/ - 0 logMAR). The BCVA of the group undergoing IOL implantation was statistically higher (p = 0.007). Nystagmus was present in 6 out of 22 patients who left aphakic where postoperative nystagmus was recorded 3 out of 18 patients with IOL implanted. Two cases showed posterior capsule opasifi cation, where, 1 retinal detachment, 1 glaucoma and 1 IOL subluxation cases were recorded as complications.

Conclusion: IOL implantation was associated with good visual prognosis and the presence of nystagmus was associated with poor visual prognosis in bilateral childhood cataracts. Keywords : Pediatric cataract, Congenital cataract, Bilateral cataract, Nystagmus, Intraocular lens
