PURPOSE: There are very few studies that describe the technique and results of double-headed pterygium removal and most of these have recurrence rates higher than those described for single pterygium removal. P.E.R.F.E.C.T for PTERYGIUM has a very low recurrence rate, and this study describes the recurrence rate and cosmesis when used on double-headed pterygia. METHODS: A prospective intervention series was performed on 20 eyes with a follow-up of 1 year or more with examination for recurrence and cosmetic appearance...
