To report the outcomes of autologous cultivated limbal epithelial transplantation using the healthy part of the affected eye or the fellow eye as a source of limbal stem cells in patients with unilateral, partial limbal stem cell deficiency (LSCD).

Retrospective, nonrandomized, interventional case series.

setting: L. V. Prasad Eye Institute, Hyderabad, India. study population: Patients with unilateral, partial LSCD who underwent autologous cultivated limbal epithelial transplantation between 2001 and 2011. intervention: The limbal biopsy was taken either from the healthy part of the limbus of the same eye (ipsilateral group) or from the healthy fellow eye (contralateral group). Cells were cultivated using a xeno-free explant culture technique, and cultivated cells were transplanted onto the affected surface. primary outcome measure: Success of cultivated limbal epithelial transplantation, defined as a completely epithelialized, avascular, and clinically stable corneal surface.

Seventy eyes of 70 patients were studied. The mean follow up was 17.5 ± 7 months. In 34 eyes the limbal biopsy was taken from the ipsilateral eye and in the remaining 36 eyes from the contralateral eye. Clinical success was achieved in 70.59% of eyes in the ipsilateral group and 75% of eyes in the contralateral group (P = .79). Limbal transplant survival rates at the final follow-up visit were 65.1% ± 0.09% in the ipsilateral group and 53.6% ± 0.12% in the contralateral group (P = .74).

Ocular surface restoration in partial LSCD is possible with cell-based therapy. Outcomes are similar irrespective of whether the limbal biopsy is taken from the healthy part of the ipsilateral eye or the contralateral eye.
