Background and purpose: Neonatal corneal opacities (NCO) are one of the common causes of visual impairment in infants. We present the two infants with penetrating keratoplasty (PKP) for unilateral NCO with different visual and graft outcomes, and illustrate the importance of timing of surgery, importance of visual rehabilitation, and the lack of necessity of a clear graft to achieve reasonable visual function in infants with NCO.
Patients and methods: Two infants with unilateral NCO (Peters anomaly) underwent PKP at age of 5.5 weeks (Case One) and 16 weeks (Case Two). Postoperative optical correction, amblyopia therapy, visual and graft outcomes were recorded.
Results: At the last follow-up (9.5 years in both the cases), Case One achieved a best-corrected visual acuity (BCVA) of 20/80 with -22 D of contact lens. The graft had a small clear zone centrally but otherwise was opacified to some extent. Case Two achieved a BCVA of 20/125 at 30 cms eccentrically with a clear graft. Case Two was uncooperative for amblyopia therapy and optical treatment.
Conclusion: For a successful visual outcome in NCO, early PKP, aggressive amblyopia therapy, optical correction, and commitment from the parents for longterm follow-up and demanding treatment are required.
