A Study of Pterygium Surgery with Stem Cell Limbo-Conjunctival Graft in Preventing Recurrence.
Ophthalmol Update Jan ;13(1):15-8.

Purpose: The purpose of this study was to evaluate the efficacy, safety and recurrence rate by using superotemporal conjuntivo-limbal auto graft transplantation technique in the surgical management of pterygium in a population in which pterygia are more prevalent with maximum sun exposure. Material & Methods: A total of 74 patients with primary and recurrent pterygium was surgically treated by the technique of excision and covering with free conjunctivo ?limbal autograft between June 2010 and May 2013 at Ch Rehmat Memorial Hospital/Continental Medical College Lahore. All surgeries were performed under local anesthesia by using limbal counjunctival stem cell graft from the ipsilateral eye and stitched by using 10/0 nylon on to the bare area. During follow-up examination, the best corrected visual acuity, slit lamp examination and complication, recurrence rate were recorded. Results: Recurrence was seen in 4(5.4%) cases, graft disinsertion 2(2.70%) cases, pygonic granuloma 1(1.5%) case, these were dealt with minor surgical revision. Uncorrected visual acuity improved after surgery in 62(83.8%) cases. Conclusion: Conjuntivo-limbal autografting is a simple, safe and minimally invasive technique and it is recommended for the management of both primary and recurrent ptergia in Pakistani population.
