  • Title: Combined penetrating keratoplasty and trabeculectomy with mitomycin C.
    Author: WuDunn D, Alfonso E, Palmberg PF.
    Journal: Ophthalmology; 1999 Feb; 106(2):396-400. PubMed ID: 9951497.
    Abstract:
    OBJECTIVE: To evaluate corneal graft survival and intraocular pressure control in eyes that have undergone combined penetrating keratoplasty and trabeculectomy with mitomycin C (MMC). DESIGN: Retrospective noncomparative case series. INTERVENTION: Penetrating keratoplasty combined with trabeculectomy with MMC and other surgical procedures. PARTICIPANTS: Twenty-four eyes of 22 patients undergoing combined penetrating keratoplasty and trabeculectomy with mitomycin C. MAIN OUTCOME MEASURES: Corneal graft clarity and intraocular pressure control. RESULTS: The cumulative probability of corneal graft survival was 85% at 1 year and 60% at 2 years. The cumulative probability of adequate pressure control was 67% at 3 months, 55% at 12 months, and 50% at 24 months. The incidence of bleb failure was higher in cases involving additional concomitant procedures, such as anterior vitrectomy, lens implantation or exchange, and drainage tube implantation. CONCLUSIONS: Combined penetrating keratoplasty and trabeculectomy with mitomycin C is associated with good corneal graft survival but also a risk of early failure of intraocular pressure control. Other concomitant procedures during the combined penetrating keratoplasty/trabeculectomy may increase the risk of early bleb failure.
